Typing `selector -qa` into nu would cause a `panic!`
This was the case because the inner loop incremented the `idx`
that was only checked in the outer loop and used it to index into
`lite_cmd.parts[idx]`
With the fix we now break loop.

Now, Echo converts multiple values in a ValueStream, but it simply
forwards a single Value; if no PipelineData is detected as an input, an
empty string is returned as a single Value.
Values to echo need to be extracted from the call, and then converted
into PipelineData.
I also updated the first example so that its result is a List,
as in the reference implementation.
The introduction of `use <file.nu>` added the possibility of calling
`working_set.add_file()` more than once per parse pass. Some of the
logic handling the file contents offsets prevented it from working and
hopefully, this commit fixes it.
Currently, `use spam.nu` creates a module `spam`. Therefore, after the
first `use`, it is possible to call both `use spam.nu` and `use spam`
with the same effect.
In some rare cases, the global predeclarations would clash, for example:
> module spam { export def foo [] { "foo" } }; def foo [] { "bar" }
In the example, the `foo [] { "bar" }` would get predeclared first, then
the predeclaration would be overwritten and consumed by `foo [] {"foo"}`
inside the module, then when parsing the actual `foo [] { "bar" }`, it
would not find its predeclaration.
Hiding definitions now should work correctly with repeated use of 'use',
'def' and 'hide' keywords.
The key change is that 'hide foo' will hide all definitions of foo
that were defined/used within the scope (those from other scopes are
still available). This makes the logic simpler and I found it leads to a
simpler mental map: you don't need to remember the order of defined/used
commands withing the scope -- it just hides all.
See cc3653cfd9 for more on the `-c` flag.

Very often we need to work with tables (say extracted from unstructured data or some
kind of final report, timeseries, and the like).
It's inevitable we will be having columns that we can't know beforehand what their names
will be, or how many.
Also, we may end up with certain cells having values we may want to remove as we explore.
Here, `update cells` fundamentally goes over every cell in the table coming in and updates
the cell's contents with the output of the block passed. Basic example here:
```
> [
[ ty1, t2, ty];
[ 1, a, $nothing]
[(wrap), (0..<10), 1Mb]
[ 1s, ({}), 1000000]
[ $true, $false, ([[]])]
] | update cells { describe }
───┬───────────────────────┬───────────────────────────┬──────────
# │ ty1 │ t2 │ ty
───┼───────────────────────┼───────────────────────────┼──────────
0 │ integer │ string │ nothing
1 │ row Column(table of ) │ range[[integer, integer)] │ filesize
2 │ string │ nothing │ integer
3 │ boolean │ boolean │ table of
───┴───────────────────────┴───────────────────────────┴──────────
```
and another one (in the examples) for cases, say we have a timeseries table generated and
we want to remove the zeros and have empty strings and save it out to something like CSV.

Previously, `source` used `expand_path()` which does not follow

As a follow up, I improved the source error messages so they now tell
why the source file could not be canonicalized or read into string.
This means that commands cannot start with these characters.
However, we get the following benefits:
* Negative numbers > -10
* Ranges with negative numbers > -10..-1
* Left-unbounded ranges > ..10

```
Adding a more flexible approach for creating error values. One use case, for instance is the
idea of a test framework. A failed assertion instead of printing to the screen it could create
tables with more details of the failed assertion and pass it to this command for making a full
fledge error that Nu can show. This can (and should) be extended for capturing error values as well
in the pipeline. One could also use it for inspection.
For example: `.... | error inspect { # inspection here }`
or "error handling" as well, like so: `.... | error capture { fix here }`
However, we start here only with `error make` that creates an error value for you with limited support for the time being.
* Add subcommand `into filesize`
It's currently not possible to convert a number or a string containing a number
into a filesize. The only way to create an instance of filesize type today is
with a literal in nushell syntax. This commit adds the `into filesize`
subcommand so that file sizes can be created from the outputs of programs
producing numbers or strings, like standard unix tools.
There is a limitation with this - it doesn't currently parse values like `10 MB`
or `10 MiB`, it can only look at the number itself. If the desire is there, more
flexible parsing can be added.
* fixup! Add subcommand `into filesize`
* fixup! Add subcommand `into filesize`
* feat: spawn the executables directly if possible
This pull request changes nu-command so that it spawns the process directly if:
- They are a `.exe` on Windows
- They are not a `.sh` or `.bash` on not windows.
Benefits:
- As I explained in [this comment](https://github.com/nushell/nushell/issues/3898#issuecomment-894000812), this is another step towards making Nushell a standalone shell, that doesn't need to shell out unless it is running a script for a particular shell (cmd, sh, ps1, etc.).
- Fixes the bug with multiline strings
- Better performance due to direct spawning.
For example, this script shows ~20 ms less latency.

* Allow different names for ...rest
* Resolves#3945
* This change requires an explicit name for the rest argument in `WholeStreamCommand`,
which is why there are so many changed files.
* Remove redundant clone
* Add tests
* Allow environment variables to be hidden
This change allows environment variables in Nushell to have a value of
`Nothing`, which can be set by the user by passing `$nothing` to
`let-env` and friends.
Environment variables with a value of Nothing behave as if they are not
set at all. This allows a user to shadow the value of an environment
variable in a parent scope, effectively removing it from their current
scope. This was not possible before, because a scope can not affect its
parent scopes.
This is a workaround for issues like #3920.
Additionally, this allows a user to simultaneously set, change and
remove multiple environment variables via `load-env`. Any environment
variables set to $nothing will be hidden and thus act as if they are
removed. This simplifies working with virtual environments, which rely
on setting multiple environment variables, including PATH, to specific
values, and remove/change them on deactivation.
One surprising behavior is that an environment variable set to $nothing
will act as if it is not set when querying it (via $nu.env.X), but it is
still possible to remove it entirely via `unlet-env`. If the same
environment variable is present in the parent scope, the value in the
parent scope will be visible to the user. This might be surprising
behavior to users who are not familiar with the implementation details.
An additional corner case is the the shorthand form of `with-env` does
not work with this feature. Using `X=$nothing` will set $nu.env.X to the
string "$nothing". The long-form works as expected: `with-env [X
$nothing] {...}`.
* Remove unused import
* Allow all primitives to be convert to strings
Given we can write nu scripts. As the codebase grows, splitting into many smaller nu scripts is necessary.
In general, when we work with paths and files we seem to face quite a few difficulties. Here we just tackle one of them and it involves sourcing
files that also source other nu files and so forth. The current working directory becomes important here and being on a different directory
when sourcing scripts will not work. Mostly because we expand the path on the current working directory and parse the files when a source command
call is done.
For the moment, we introduce a `lib_dirs` configuration value and, unfortunately, introduce a new dependency in `nu-parser` (`nu-data`) to get
a handle of the configuration file to retrieve it. This should give clues and ideas as the new parser engine continues (introduce a way to also know paths)
With this PR we can do the following:
Let's assume we want to write a nu library called `my_library`. We will have the code in a directory called `project`: The file structure will looks like this:
```
project/my_library.nu
project/my_library/hello.nu
project/my_library/name.nu
```
This "pattern" works well, that is, when creating a library have a directory named `my_library` and next to it a `my_library.nu` file. Filling them like this:
```
source my_library/hello.nu
source my_library/name.nu
```
```
def hello [] {
"hello world"
}
```
```
def name [] {
"Nu"
end
```
Assuming this `project` directory is stored at `/path/to/lib/project`, we can do:
```
config set lib_dirs ['path/to/lib/project']
```
Given we have this `lib_dirs` configuration value, we can be anywhere while using Nu and do the following:
```
source my_library.nu
echo (hello) (name)
```
* Allow sourcing paths with emojis
* Add source command tests for emoji paths

We introduce it here and allow it to work with regular lists (tables with no columns) as well as symmetric tables. Say we have two lists and wish to zip them, like so:
```
[0 2 4 6 8] | zip {
[1 3 5 7 9]
} | flatten
───┬───
0 │ 0
1 │ 1
2 │ 2
3 │ 3
4 │ 4
5 │ 5
6 │ 6
7 │ 7
8 │ 8
9 │ 9
───┴───
```
In the case for two tables instead:
```
[[symbol]; ['('] ['['] ['{']] | zip {
[[symbol]; [')'] [']'] ['}']]
} | each {
get symbol | $'($in.0)nushell($in.1)'
}
───┬───────────
0 │ (nushell)
1 │ [nushell]
2 │ {nushell}
───┴───────────

* Mitigate history file bug in Rustyline
Rustyline's duplicate ignoring code has a bug that can cause data loss and
history file corruption. Testing seems to indicate that disabling this behavior
and allowing duplicates will prevent the bug from showing up. Many people have
complained about this issue, I think it is worthwhile to fix the bug at the cost
of permitting duplicate history entries.
Upstream bug: https://github.com/kkawakam/rustyline/issues/559
* Increase Rustyline historyfile limit
Rustyline will only store 100 history items by default. This is quite a small
limit for a shell that people use as a daily driver. Especially when the
deduplication code is removed, we will hit that limit quickly and start to lose
history. This commit bumps the limit up to 10k. We can discuss if this is an
inappropriate limit or if we should allow users to specify this setting in their
nushell config file instead.
We very well support `nth 0 2 3 --skip 1 4` to select particular rows and skip some using a flag. However, in practice we deal with tables (whether they come from parsing or loading files and whatnot) where we don't know the size of the table up front (and everytime we have these, they may have different sizes). There are also other use cases when we use intermediate tables during processing and wish to always drop certain rows and **keep the rest**.
Usage:
```
... | drop nth 0
... | drop nth 3 8
```
The nu-serde crate allows us to become much more generic with respect to how we
convert output to `nu-protocol::Value`s. This allows us to remove a lot of the

* Add the nu-serde crate
nu-serde is a crate that can be used to turn a value implementing
`serde::Serialize` into a `nu-protocol::Value`. This has the potential to
significantly simplify plugin authorship.
This crate was the previously independent
[serde-nu](https://github.com/lily-mara/serde-nu) but the nushell maintainers
expressed an interest in having it added to the mainline nushell repository.
* fixup! Add the nu-serde crate
Some environment variables, such as `RUST_LOG` include equals signs. Nushell
should support this in the shorthand environment variable syntax so that
developers using these variables can control them easily. We accomplish this by
swapping `std::str::split` for `std::str::splitn`, which ensures that we only
consider the first equals sign in the string instead of all of them, which we
did previously.

Select used to ignore absent values resulting in "squashing" where

* kind of works but not what we really want
* updated `into binary` and `first` to work better together
* attempt to fix wasm build problem
* attempt #2 to fix wasm stuff
This brings with it a reduction in the number of duplicated
dependencies that it has and the overhead it imposes on our
build.
The number of crates that need to be built for
`cargo build --features extra` drops by roughly 50.
On Windows, we used the `is-exeuctable` crate but on Unix, we
duplicated the check that it did, with one difference: We also
looked at whether or not it was a symlink.
The `is-executable` crate uses `std::fs::metadata` which follows
symlinks, so this scenario should never occur here, as it will
return the metadata for the target file.
Using the `is-executable` crate on both Unix and Windows lets us
make it non-optional. This lets us remove the `executable-support`
feature. (It is worth noting that this code didn't compile on
Windows when the `executable-support` feature was not specified.)
Right now, there is an alternate code path for `target_arch` being
`wasm32`. This isn't exactly correct as it should probably handle
something different for when the `target_os` is `wasi`.
Nothing used the `ptree` feature or optional dependency within
`nu-command` except to include it within the `version` output. This
may be related to when `nu-cli` also had a `ptree` feature, but
I'm not sure.
That leaves the code within `nu_plugin_tree` as the sole remaining
user of `ptree`, which is already covered by the feature `tree`
and included in the `version` output.

In Nu we have variables (E.g. $var-name) and these contain `Value` types.
This means we can bind to variables any structured data and column path syntax
(E.g. `$variable.path.to`) allows flexibility for "querying" said structures.
Here we offer completions for these. For example, in a Nushell session the
variable `$nu` contains environment values among other things. If we wanted to
see in the screen some environment variable (say the var `SHELL`) we do:
```
> echo $nu.env.SHELL
```
with completions we can now do: `echo $nu.env.S[\TAB]` and we get suggestions
that start at the column path `$nu.env` with vars starting with the letter `S`
in this case `SHELL` appears in the suggestions.

exception of duration for both tracks and the entire file itself because
there is still an issue. However, that will be fixed in the upcoming
patches
* fix: UntaggedValue::duration() serializes correctly now
Previous to this patch, there was an issue where when you would use
UntaggedValue::duration() it would result in an invalid JSONRPC
resulting string when using the protocol. This patch fixes this issue
* Mp4: Duration fixed for file and tracks
* plugins: Add plugin extra to src/plugins
* Mp4: Replace unwrap() with expect()
* Fix: Remove test mp4 file
We've relied on `clap` for building our cli app bootstrapping that figures out the positionals, flags, and other convenient facilities. Nu has been capable of solving this problem for quite some time. Given this and much more reasons (including the build time caused by `clap`) we start here working with our own.
* enable theming of the command line syntax
* added missing flatshape, sorted flatshapes for easier reading.
* sorted flat shapes again and saved it this time
* added sample rwb.json syntax them file to docs
* Fix and clarify description of 'exec'
Most importantly, I added the information that it replaces the current
process.
* Convert exec to OutputStream; Remove unused trait
* Remove dead code & unused imports on non-unix
* Sample command
* Join command with checks
* More dataframes commands
* Groupby and aggregate commands
* Missing feature dataframe flag
* Renamed file
* New commands for dataframes

* removed name from nu_dataframe
* commands to save to parquet and csv
* polars new version
* new dataframe commands
* series type and print
* Series basic arithmetics
* Add new column to dataframe
* Command names changed to nushell standard
* Throw an error if path failed to expand
Previously, it just repeated the non-expanded path.
* Allow expanding non-existent paths
This commit has a strange error in examples.
* Specify span manually in examples; Add an example
* Expand relative path without requiring cwd
* Remove redundant tilde expansion
This makes the tilde expansion in relative paths dependant on "dirs"
feature.
* Add missing example result
* Adjust path expand description
* Fix import error with missing feature
Previous to this commit, the sysinfo crate would show blank `brand` for
Apple M1 architectures whenever you would run `sys | get cpu`.
I have fixed the issue in sysinfo, so bumping the dependency version to 0.18.2
means brand now is retrieved successfully on M1 architectures.
Changes:
* Bug fix - bat adds markers only when a file path is passed and it can use git2
on it. It doesn't add markers when bytes are passed. Hence, the code is
adjusted accordingly. The sideeffect is files being opened multiple
times and its content being unnecessarily loaded in memory.
* Refactoring of the crate - Config is extracted to its struct file.
Repetitive blocks of code are dried and nested conditionals are
flattened.
* Sample command
* Join command with checks
* More dataframes commands
* Groupby and aggregate commands
* Missing feature dataframe flag
* Renamed file
* New commands for dataframes
* error parser and df reference
* filter command for dataframes
* removed name from nu_dataframe
* commands to save to parquet and csv
Using the `*` wildcard should not attempt to delete files with a leading dot
unless the more explicit `.*` is used. `rm *` should also not attempt to delete
the current directory or its parent directory (`.` and `..`). I have resolved
this bug as well in a less satisfactory way. I think it may be the case that we
can only disambiguate the `.` and `..` path segments by using `Path::display`.
Here is a short list of alternatives that I tried:
- `Path::ends_with()` can detect `/..` but not `/.`.
- `Path::iter()` and `Path::components()` leave out `/.`.
- `Path::file_name()` normalizes `/.` to the parent component's file name.
Fixes#3508
* Fix parser expanding dots where it shouldn't
Previously, the parser would expand "a...b" as "a../..b". Now, >2 dots
are only expanded when the whole path component consists of dots (i.e.,
"..." expands to "../.." while "a...b" stays as it is).
* Respect OS separator when expanding >2 dots
"..." now expands to either "../.." or "..\..", based on the host OS.
* Add the load-env command
load-env can be used to add environment variables dynamically via an
InputStream. This allows developers to create tools that output environment
variables as key-value pairs, then have the user load those variables in using
load-env. This supplants most of the need for an `eval` command, which is
mostly used in POSIX envs for setting env vars.
Fixes#3481
* fixup! Add the load-env command
Not all lite command's first part denotes a real command (for cases like sub commands that it's second lite part accounts for the command name). This is important so that we can refer to it's span correctly. Here we fix to include the command's name span correctly whether it's a command or sub command when reporting missing flag errors.
* Allow querying the current path separator
* Convert char command to engine-p
* Wrap char args into struct
* Add --list option to char command
This lists all the available character names, along with the character
and its unicode points.
* commands to engine
* Correction of error in parser
* Added detailed regex error to parse
* better regex error parsing
* clippy corrections
* parse example with test
* secondary error for regex
* removed clone in error parser
* Secondary error message
The `date utc` command was removed in this PR:

It was too error prone when positional arguments were used with the rest
arguments. Now, you need to explicitly state from which position you
want to count the rest args (e.g., `rest(0)`).

The ps plugin has an unnecessary call to `std:🧵:sleep(500ms)` that
delays runtime by 500ms. Additionally, there is a call to
`sysinfo::SystemExt::refresh_process`, which is not required as the previous
call to sysinfo::SystemExt::refresh_all handles the "refresh" of all processes
without a need to do this individually. Combining both of these improvements
means that running ps runs nearly instentaneously.
Fixes#3402
* Convert "random bool" to engine-p
Also implements FromValue for Tagged<BigDecimal> and Tagged<f64>.
* Convert "random dice" to engine-p
* Convert "random uuid" to engine-p
* Covert "random chars" to engine-p
* Convert "random" command to engine-p
* Implement minmax for Range; Simplify range command
* Port random integer to enginep; New FromValue impl
Now, FromValue is implemented for Tagged<Range> to allow extracting args
into this type.
* Make sure range value extraction fails properly
The range endpoint extraction methods now return error instead of
silently clipping the value. This now makes `random integer ..-4` fail
properly since -4 can't be cast as u64.
* Port random decimal to enginep & Refactor
This added a way to interpret Range limits as f64 and a Primitive helper
to get its value as f64.
A side effect of this commit is that it is now possible to specify the
command bounds as true decimals. E.g., `random decimal 0.0..3.14` does
not clip 3.14 to 3.
* Add first prototype of functionality to parse numbers in parantheses (). Needs testing and more wide-testing+integration
* Fix styling issue
* Try something else by copying existing matching code
* Fix formatting
* Fix the parser to accept numbers in paranthesis. Not really happy with the code, but let's see
* Refactor to only use once the parsing of strings into numbers
* Remove errors that are not used

If nu fails to load a user config on startup, no helper is set and the
later call to `rl.helper_mut()` will panic. There may be better ways to
handle this long-term, but printing an error about the failure to parse
the config and then starting with default values seems reasonable.
* Removes arg serialization
* action stream -> output stream
* uses nu_protocol::Range instead of NumericRange
* random missing newline I found in the code
* add nu-pretty-hex, add into binary, update binaryview
* updated parameter name, updated examples
* fixed nu-pretty-hex test
* fixed tests again! and added a no color option to pretty-hex
* Fix array index out of bounds error.
Error occured when computing levenshtein_distance of two strings where
str.len() is not equal to str.chars().collect::<Vec<_>>().len()
* Add test for levenshtein_distance
It compiles and works without errors, but the pager is not asynchronous
anymore (i.e., you need to wait for `seq 1 1000000` to finish before the
pager is displayed).
* Add new path parse subcommand
This includes a slight refactor to all the path subcommand `action()`
functions.
* Remove filestem and extension; Fix example
* Add additional description to path parse
* Put join arg behind flag; Fix missing import (Win)
* Fix error when column path is passed as arg
* Add structured path joining
Structured path is implicitly joined at every patch subcommand call.
* Fix existing path join tests; Fix rustfmt
* Remove redundant 'static lifetime (clippy)
* Add initial impl of path split subcommand
* Add ability to join path from parts
* Fix wrong results in path split examples
* Fix remaining asyncs after engine change
* Do not wrap split path parts into table
When the input is just a list of values, the `path split` command will
split each value directly into the output stream, similar to
`split-row`. Column path--specified values are still wrapped into a
table so they can still be used to replace table fields.
* Join list of values instead of going one-by-one
When `path join` encounters a list of values, it attempts to join them,
instead of going one-by-one like the rest of the path commands. You can
still `each { echo $it | path join }` to join them one-by-one, if the
values are, e.g., tables.
Now, the behavior of `path split` and `path join` should match the
`split-row` and `str collect` counterparts and should hopefully align
better with user's expectations.
* Make sure path join detects structured path
* Fix panic on empty input stream
Also, doesn't collect input into vector unnecessarily.
* Fix path join not appending value
* Remove argument serialization
* Make better errors; Misc refactor
* OsStr -> String encoding is now lossy, instead of throwing an error
* The consequence is action() now always returns Value instead of Result
* Removed redundant handle_value() call in `path join`
* Fix possible incorrect error detection in `path split`
* Applied rustfmt + clippy
* Add more usage, examples & test; Fix type error
The 'parent' column was required to be a path but didn't work with
string.
* Add more help & examples; Maybe fix Windows error
* Refactor operate function
Reducing code repetition
* Review usages and examples
* Add the option to manually specify the extension
* Add more tests; Fix failures on Windows
* Move path commands to engine-p
* Small refactor
* add query json plugin for experimentation
* add some error handling
* closer but Kind::Array is still horked
* unravel the table so the output looks right

If built without `trash_support`, nu should explicitly reject attempts to use `rm` with the `--trash` option, or with a config file which includes `rm_always_trash = true`.
As of 42fac72, there doesn't seem to be any guard in the `#[cfg(not(feature = "trash-support"))]` block of `filesystem_shell::rm`, leading to the behavior described in #3116, where builds without the trash-support feature will delete things permanently regardless of flags/config options.
This should close#3116

Before storing an entry into the history nushell will check if the entry
consists only of whitespaces and if so, it does not store it in the history and
this avoids newline repetition when user is navigating in the history.

We can check if `any` (or `all`) rows of tables match predicates.
Small `all?` example: Given the following table with `services` running:
```
> echo [[status]; [UP] [UP]]
───┬────────
# │ status
───┼────────
0 │ UP
1 │ UP
───┴────────
```
We can ask if all services are UP, like so:
```
> echo [[status]; [UP] [UP]] | all? status == UP
true
```
* Fix any? signature.

Improvements overall to Nu. Also among the changes here, we can also be more confident towards incorporating `3041`. End to end tests for checking envs properly exported to externals is not added here (since it's in the other PR)
A few things added in this PR (probably forgetting some too)
* no writes happen to history during test runs.
* environment syncing end to end coverage added.
* clean up / refactorings few areas.
* testing API for finer control (can write tests passing more than one pipeline)
* can pass environment variables in tests that nu will inherit when running.
* No longer needed.
* no longer under a module. No need to use super.
* add ability to cd to ~/blah. tested on windows.
* added dirs_next
* put change behind feature for linux-minimal/wasm
* clippy
* holy crap minimal, i'm about done with you!
* add support for timestamp-based time conversion by specifing timezone or 'UTC/Local'
* [fix] fix the wrong test sample
* code formating
* code formating and import missing mod to test
* code formating again
the initial setup-commands of nushell were executed without loading environment variables
this resulted in the PATH not being available at this point until an external command was run once
which resulted in env_vars being added

While the "main" separator in Windows is the backslash, it supports the
forward slash as a separator too.
Add support for this so that the behavior is similar to the way Windows
PowerShell handles the forward slash: it is recognized as a separator,
and when using <tab> for path completion the slash is reversed.
* Playground infraestructure (tests, etc) additions.
A few things to note:
* Nu can be started with a custom configuration file (`nu --config-file /path/to/sample_config.toml`). Useful for mocking the configuration on test runs.
* When given a custom configuration file Nu will save any changes to the file supplied appropiately.
* The `$nu.config-path` variable either shows the default configuration file (or the custom one, if given)
* We can now run end to end tests with finer grained control (currently, since this is baseline work, standard out) This will allow to check things like exit status, assert the contents with a format, etc)
* Remove (for another PR)
* Make opening a directory enter it.
Not sure if this change is wanted, but I'm not sure what else opening a directory could mean.
And I find myself accidentally using `open <dir>` to mean `enter <dir>`
* Add example to open directory
* Open dir should list it's contents
* Update example description and fix style
* update docs to refer to length instead of count
* rename count to length
* change all occurrences of 'count' to 'length' in tests
* format length command
* Move run_script to engine
* Add which dep and feature to engine
* Change unwrap to expect
* Add wasm specification
* Remove which from default, add specification correctly
* Add nu-platform-specifics
* Move is_external_cmd to platform_specifics
* Add is_external_cmd to host and use it instead of nu_platform directly
* Clean up if else logic in is_external_cmd
* Bump nu-platform-specifics version
* Pass context to print_err
* Commit cargo.lock
* Move print functions to own module inside nu-engine
* Hypocratic change to run windows-nightly again
* Add import for Ordering
* Move printing of error to host
* Move platform specific which functionality to basic host
* Allow no use of cmd_name
* Fix windows compile issue
For now the trash doesn't work because the trash-support flag isn't enabled in nu-engine
crate, so make it work by adding this flag.

* Split help message into brief and full help
Demonstrate on ansi command
Brief help is printed when running `help commands` so it doesn't clutter
the table. Full help is printed when normal help message is requested
(e.g., `help ansi`, `ansi --help`, etc.).
* Split long command descriptions
Some are not split, just edited to be shorter.
* Capitalize the usage of all commands
* Make sure every usage ends with dot
* Fix random typo
* use the InputHandler functionality from minus
* respond to Q and ESC character to quit
* use arijit79/minus main branch until new release is pushed
* rename NushellMinusInputHandler to MinusInputHandler
* Refactor path subcommand argument handling
DefaultArguments are no longer passed to each subcommand. Instead, each
subcommand has its own Path<xxx>Arguments. This means that it is no
longer necessary to edit every single path subcommand source file when
changing the arguments struct.
* Add new path join subcommand
Makes it easier to create new paths. It's just a wrapper around Rust's
Path.join().
* Add option to invert match command selection
* Fix rustfmt error
* Rename match --exclude to --invert
To be more descriptive and conform to e.g. grep or ripgrep -v flag.
Also simplified the --invert flag description.
* Fix formatting when description got shorter

`drop` is used for removing the last row. Passing a number allows dropping N rows.
Here we introduce the same logic for dropping columns instead.
You can certainly remove columns by using `reject`, however, there could be cases
where we are interested in removing columns from tables that contain, say, a big
number of columns. Using `reject` becomes impractical, especially when you don't
care about the column names that could either be known or not known when exploring
tables.
```
> echo [[lib, extension]; [nu-core, rs] [rake, rb]]
─────────┬───────────
lib │ extension
─────────┼───────────
nu-core │ rs
rake │ rb
─────────┴───────────
```
```
> echo [[lib, extension]; [nu-core, rs] [rake, rb]] | drop column
─────────
lib
─────────
nu-core
rake
─────────
```
There are many use cases. Here we introduce the following:
- The rows can be rolled `... | roll` (up) or `... | roll down`
- Columns can be rolled too (the default is on the `left`, you can pass `... | roll column --opposite` to roll in the other direction)
- You can `roll` the cells of a table and keeping the header names in the same order (`... | roll column --cells-only`)
- Above examples can also be passed (Ex. `... | roll down 3`) a number to tell how many places to roll.
Basic working example with rolling columns:
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit1 │ bit2 │ bit3 │ bit4 │ bit5 │ bit6 │ bit7 │ bit8
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 0 │ 0 │ 0 │ 1 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
We want to "shift" three bits to the left of the bitstring (four in decimal), let's try it:
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
| roll column 3
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit4 │ bit5 │ bit6 │ bit7 │ bit8 │ bit1 │ bit2 │ bit3
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 1 │ 0 │ 0 │ 0 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
The tables was rolled correctly (32 in decimal, for above bitstring). However, the *last three header names* look confusing.
We can roll the cell contents only to fix it.
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
| roll column 3 --cells-only
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit1 │ bit2 │ bit3 │ bit4 │ bit5 │ bit6 │ bit7 │ bit8
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 1 │ 0 │ 0 │ 0 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
There we go. Let's compute it's decimal value now (should be 32)
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| roll column 3 --cells-only
| pivot bit --ignore-titles
| get bit
| reverse
| each --numbered { = $it.item * (2 ** $it.index) }
| math sum
32

The autoenv logic mutates environment variables in the running session as
it operates and decides what to do for trusted directories containing `.nu-env`
files. Few of the ways to interact with it were all in a single test function.
We separate out all the ways that were done in the single test function to document
it better. This will greatly help once we start refactoring our way out from setting
environment variables this way to just setting them to `Scope`.
This is part of an on-going effort to keep variables (`PATH` and `ENV`)
in our `Scope` and rely on it for everything related to variables.
We expect to move away from setting (`std::*`) envrironment variables in the current
running process. This is non-trivial since we need to handle cases from vars
coming in from the outside world, prioritize, and also compare to the ones
we have both stored in memory and in configuration files.
Also to send out our in-memory (in `Scope`) variables properly to external
programs once we no longer rely on `std::env` vars from the running process.

* Rename param_flag_list to signature

* Fix clippy lint
* Change imports to new lexer structure
Before, ps would not insert a value if the process didn't have a parent.
Now, ps will insert an empty cell. This caused broken tables as some
rows didn't have all the columns.
* Document the lexer and lightly improve its names
The bulk of this pull request adds a substantial amount of new inline
documentation for the lexer. Along the way, I made a few minor changes
to the names in the lexer, most of which were internal.
The main change that affects other files is renaming `group` to `block`,
since the function is actually parsing a block (a list of groups).
* Further clean up the lexer
- Consolidate the logic of the various token builders into a single type
- Improve and clean up the event-driven BlockParser
- Clean up comment parsing. Comments now contain their original leading
whitespace as well as trailing whitespace, and know how to move some
leading whitespace back into the body based on how the lexer decides
to dedent the comments. This preserves the original whitespace
information while still making it straight-forward to eliminate leading
whitespace in help comments.

* Update def docs
* Add rest arg to def
This commit applied adds the ability to define the rest parameter of a def
command. It does not implement the functionality to expand the rest argument in
a user defined def function.
The rest argument has to be exactly worded "...rest".
Example after this PR is applied:
file test.nu
```shell
def my_command [
...rest:int # My rest arg
] {
echo 1 2 3
}
```
```shell
> source test.nu
> my_command -h
Usage:
> my_command ...args {flags}
Parameters:
...args: My rest arg
Flags:
-h, --help: Display this help message

* Put parse_definition related funcs into own module
* Add failing lexer test
* Implement Parsing of definition signature
This commit applied changes how the signature of a function is parsed. Before
there was a little bit of "quick-and-dirty" string-matching/parsing involved.
Now, a signature is a little bit more properly parsed.
The grammar of a definition signature understood by these parsing-functions is
as follows:
`[ (parameter | flag | <eol>)* ]`
where
parameter is:
`name (<:> type)? (<,> | <eol> | (#Comment <eol>))?`
flag is:
`--name (-shortform)? (<:> type)? (<,> | <eol> | (#Comment <eol>))?`
(Note: After the last item no <,> has to come.)
Note: It is now possible to pass comments to flags and parameters
Example:
[
d:int # The required d parameter
--x (-x):string # The all powerful x flag
--y (-y):int # The accompanying y flag
]
(Sadly there seems to be a bug (Or is this expected behaviour?) in the lexer, because of which `--x(-x)` would
be treated as one baseline token and is therefore not correctly recognized as 2. For
now a space has to be inserted)
During the implementation of the module, 2 question arose:
Should flag/parameter names be allowed to be type names?
Example case:
```shell
def f [ string ] { echo $string }
```
Currently an error is thrown
* Fix clippy lints
* Remove wrong comment
* Add spacing
* Add Cargo.lock
* move basic_shell_manager to nu-engine
* move basic_evaluation_context to nu-engine
* fix failing test in feature which commands/classified/external.rs
We split off the evaluation engine part of nu-cli into its own crate. This helps improve build times for nu-cli by 17% in my tests. It also helps us see a bit better what's the core engine portion vs the part specific to the interactive CLI piece.
There's more than can be done here, but I think it's a good start in the right direction.
* Obay precedence rules in which; Fix#2875
Before which did not obay the precedence of alias before def commands.
Furthermore, `which -a echo` would only report either an alias or a def command or an
internal command with the provided name. Not all.
With this commit applied its fixed :)
Example:
```shell
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> def echo [] {^echo hi}
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> echo
hi
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> which -a echo

* Fix clippy lint
* Fix vec always Some even if empty
This commit applied adds comments preceding a command to the LiteCommands new
field `comments`.
This can be usefull for example when defining a function with `def`. Nushell
could pick up the comments and display them when the user types `help my_def_func`.
Example
```shell
def my_echo [arg] { echo $arg }
```
The LiteCommand def will now contain the comments `My echo` and `It's much
better :)`.
The comment is not associated with the next command if there is a (or multiple) newline
between them.
Example
```shell
echo 42
```
This new functionality is similar to DocStrings. One might introduce a special
notation for such DocStrings, so that the parser can differentiate better
between discardable comments and usefull documentation.
* Update dependencies
* Document the lexer and lightly improve its names
The bulk of this pull request adds a substantial amount of new inline
documentation for the lexer. Along the way, I made a few minor changes
to the names in the lexer, most of which were internal.
The main change that affects other files is renaming `group` to `block`,
since the function is actually parsing a block (a list of groups).

v0.29.0 and earlier versions of `uom` fail to compile on nightly because
of now-ambiguous trait bounds. The issue was corrected in v0.30.0 of
`uom`. `uom` and `heim` dependencies have been updated to the
latest version to include this fix and allow nushell to compile on
nightly.

I think this still needs some refinement. Maybe we don't want to show
the separator all the time, omitting the defaults or the separator
on other formats.

2 new functions have been added: get_result_shape_of_math_expr and
get_result_shape_of_math_expr_or_insert_dependency
* Remove flattening of deep binary expressions
Previously deep binary expressions have been flattened through the insertion of
fake vars. This logic was quite complicated. Now if a variable depends on the
result shape of a binary expression and the result shape can't be computed,
the variable simply depends on the whole binary.

Continuing on anchoring and improvements on Nu's overall internal commands (#2635).
`move column` sub command has been turned into the command `move` since
we use it to move exclusively columns. Examples added as well.
Fixed it to carry along any anchor locations that might be in place if
table to be moved originates from other sources.
* Add parser improvements
Previously everything starting with "$" was parsed as a column path.
With this commit applied, the lite_arg starting with $ is parsed as
the most appropriate thing
- $true/$false ==> Expression::Boolean
- $(...) ==> Invocation
- $it ==> ColumnPath
- Anything with at least one '.' ==> ColumnPath
- Anything else ==> Variable

Multiline pastes wait for the user to hit enter before running,
because they enter a special paste mode in rustyline called
'bracketed paste' by default. This commit disables that mode
by default for nushell, causing multiline pastes to be executed
immediately, treating each new line as a separate command.

* update example, fix clippy
* removed commented char
Nu has many commands that allow the nuño to customize behavior such
as UI and behavior. Today, coloring can be customized, the line editor,
and other things. The more options there are, the higher the complexity
in managing them.
To mitigate this Nu can store configuration options as nested properties.
But to add and edit them can be taxing. With column path support we can
work with them easier.
* [wasi] Update time & instant crates
In https://github.com/nushell/nushell/pull/2643 instant was updated by adding it as a hard dependency in Cargo.toml, but it's better to avoid it and only update in Cargo.lock via `cargo update -p ...`.
Additionally, updated `time` crate so that now some basic commands like `ls` work too, although formatting is pretty bad.
* Update default terminal width to 80
If termsize can't return anything, use 80 chars (e.g. on WASI).

* Implement passthrough for benchmark
Add a new option -p,--passthrough to benchmark.
With this option, the benchmark command prints its results to stdout and passes the block's output to the next command in the pipeline.
* Add execution block for benchmark -p
`benchmark --passthrough` now takes a block where the benchmark output is sent.
Example:
`benchmark -p {save bench.toml} {ls}`
* Add global mode to str trim
The global mode allows skipping non-string values,
and processes rows and tables as well
* Add tests to action with ActionMode::Global
* Add system, user and idle times to benchmark command
* Feature-gate dependency on heim in benchmark
* Reorder let bindings in benchmark
* Fully feature-gate rich-benchmark and print 0sec on zero duration
* Remove completion code from help/value shells
* Tweak the `Completer` trait for nushell.
Previously, this trait was built around rustyline's completion traits, and for
`Shell` instances. Now it is built for individual completers inside of nushell
that will complete a specific location based on a partial string. For example,
for completing a partially typed command in the command position.
We introduce the `plugin` nu sub command (`nu plugin`) with basic plugin
loading support. We can choose to load plugins from a directory. Originally
introduced to make integration tests faster (by not loading any plugins on startup at all)
but `nu plugin --load some_path ; test_pipeline_that_uses_plugins_just_loaded` does not see it.
Therefore, a `nu_with_plugins!` macro for tests was introduced on top of nu`s `--skip-plugins`
switch executable which is set to true when running the integration tests that use the `nu!` macro now..
* Implement exclusive and inclusive ranges with .. and ..=
This commit adds right-exclusive ranges.
The original a..b inclusive syntax was changed to reflect the Rust notation.
New a..=b syntax was introduced to have the old behavior.
Currently, both a.. and b..= is valid, and it is unclear whether it's valid
to impose restrictions.
The original issue suggests .. for inclusive and ..< for exclusive ranges,
this can be implemented by making simple changes to this commit.
* Fix collect tests by changing ranges to ..=
* Fix clippy lints in exclusive range matching
* Implement exclusive ranges using `..<`
Previously, we weren't expanding `~`, so `std::fs::metadata` was failing. We now
make use of `PathSuggestion` to get the actual path, as represented by a
`PathBuf`.
* remove unused dependencies
* moved umask to cfg(unix)
* changed Inflector to inflector, hoping it fixes the issue.
* roll back Inflector
* removed commented out deps now that everything looks good.
* First commit updating `config` to use subcommands (#2119)
- Implemented `get` subcommand
* Implmented `config set` as a subcommand.
* Implemented `config set_into` as subcommand
* Fixed base `config` command
- Instead of outputting help, it now outputs the list of all
configuration parameters.
* Added `config clear` subcommand
* Added `config load` and `config remove` subcommands
* Added `config path` subcommand
* fixed clippy
* initial commit for implementing groups
* each group works
* each group is slightly cleaner + added example
* Added `each window` subcommand
- No support for stride flag yet
* each window stride implemented
* Added tests and minor documentation changes
* fixed clippy
* fixed clippy again
Previously, we'd check for a `~/` prefix and then return the home directory as
the base `PathBuf`. We failed to consider pushing any of the other possible path
components into this base dir, which prevent completions more than one level
deep (for example, `~/.config/<TAB>` would fail).

* Use the cursor position for the span when between locations.
This fixes a bug where completing

would result in replacing the entire line.
* Revert to the default update implementation.
Replacing the length of the elected value was intended to do replacement when
one moves inside a quote. The problem is that a long elected suggestion could
replace bits of a pipeline that are after the cursor. For example:
ls <TAB> | get name | str collect
We ensure the partially cimpleted item doesn't include the end quote. We also
ensure that the appropriate span is replaced, not just the suggested position up
to the cursor position.
- Ensure quotes surround suggestion replacement when there are spaces.
- Ensure an appropriate quote character is chosen based on other quoting
characters being in the suggestions.
Previously, we used rustyline's filename completer. This allowed us to make
progress on the completion engine without building all the parts at once. We now
need our own filename completer to make progress.
The primary driver to having our own filename completer is that it can better
integrate with our path constructs. For example, if we have
> ls .../<TAB>
we want to show a list of suggestions that includes all files two directories up
from the current working directory. The least jarring experience to a user would
be to maintain the three dots. The easiest way for us to do this is by building
our own completer and path constructs.
Doing 'cd .' or an equal command used to modify the prompt: It appended an './' and was even
repeatable, leading to strange prompts (believe me, I tested it for too long).
This fixes#2432
* Show directories and executable for command completion.
Previously we chose from two sets for completing the command position:
1. internal commands, and
2. executables relative to the PATH environment variable.
We now also show directories/executables that match the relative/absolute path
that has been partially typed.

Previously, lite parse would stack up opening delimiters in vec, and if we
didn't close everything off, it would simply return an error with a partial form
that didn't include the missing closing delimiters. This commits adds those
delimiters so that `classify_block` can parse correctly.
The parser sees this as a positional argument, but when requesting completions
this could be either a filename that starts with a hyphen, or it could be a
flag. This expands the completion engine's interface to return a vec of possible
completion locations instead of an optional one, because we want to show all
possibilities instead of assuming one or the either.
The completion engine maps completion locations to spans on a line, which
indicate whther to complete a command name, flag name, argument, and so on.
Initial implementation is simplistic, with some rough edges, since it relies
heavily on the parser's interpretation. For example
du -
if asking for completions, `-` is considered a positional argument by the
parser, but the user is likely looking for a flag. These scenarios will be
addressed in a series of progressive enhancements to the engine.

* publishing the case commands
* fix typo
* fix kebab case test
* formatting
The initial configuration refactoring already gave significant benefits
with my use case. On another note, Commands should know and ask for
configuration variables. We could, as we refactor, add the ability
for commands to tell what configuration variables knows about and
their types.
This way, completers can be used too when using `config` command if we
also add a sub command that config could set variables to.
Commands stating the config variables they know about will allow us
to implement it in `help` and display them.
* Changed time units as outlined in issue #2353.
Also applied changes to to_str for Unit - not sure if that was what was wanted.
* Forgot the tests!
* Updated primitive.rs to match changes.
* Updated where example to match changes.
* And the html test!
* Add commit to version command

* Make history location configurable
Add history-path to your config if you want an alternate history file
location
* use IndexMap.get() instead of index
Co-authored-by: Amanita Muscaria <nope>
* add 228 json html themes
removed old assets, added new zipped asset
added --list to get a list of the theme names
reworked some older theme code
added rust-embed and zip crate
removed the dark tests
* fmt
* Updated, removed excess comments
Changed usage a bit
Updated the error handling
Added some helper items in --list
* removed rustyline config duplication
set other rustyline defaults if line_editor section doesn't exist
updated keyseq_timeout to -1 if emacs mode is chosen
* change checking rustyline config to if lets
* removed some unneccessary code
Refactored out most of internal work for summarizing data opening
the door for generating charts from it. A model is introduced
to hold information needed for a summary, Histogram command is
an example of a partial usage. This is the beginning.
Removed implicit arithmetic traits on Value and Primitive to avoid
mixed types panics. The std operations traits can't fail and we
can't guarantee that. We can handle gracefully now since compute_values
was introduced after the parser changes four months ago. The handling
logic should be taken care of either explicitly or in compute_values.
The zero identity trait was also removed (and implementing this forced
us to also implement Add, Mult, etc)
Also: the `math` operations now remove in the output if a given column is not computable:
```
> ls | math sum
──────┬──────────
size │ 150.9 KB
──────┴──────────
```
* Delete unnecessary match
* Use `unwrap_or_else()`
* Whitespace was trim on file save
* Use `map_or_else()`
* Use a default to group all match arms with same output
* Clippy made me do it
* Move lite_parse tests into a submodule
* Have lite_parse return partial parses when error encountered.
Although a parse fails, we can generally still return what was successfully
parsed. This is useful, for example, when figuring out completions at some
cursor position, because we can map the cursor to something more structured
(e.g., cursor is at a flag name).
* Add two further path cmds - type and exists
* Update type.rs
Try a more universal directory
* Update type.rs
Co-authored-by: Jonathan Turner <jonathandturner@users.noreply.github.com>
* Add new path commands
basename, expand and extension. Currently there is no real error
handling. expand returns the initial path if it didn't work, the others
return empty string
* Optionally apply to path
- Removing old code for dealing with escaping, since that has moved elsewhere.
- Eliminating some match statements in favour of result/option methods.
- Fix an issue where completing inside quotes could remove the quote at the
beginning, if one already existed on the line but the replacement didn't have
a quote at the beginning.
* Refactor all completion logic into `NuCompleter`
This is the next step to improving completions. Previously, completion logic was
scattered about (`FilesystemShell`, `NuCompleter`, `Helper`, and `ShellManager`).
By unifying the core logic into a central location, it will be easier to take the
next steps in improving completion.
* Update context.rs
Co-authored-by: Jonathan Turner <jonathandturner@users.noreply.github.com>
In any other shell, stderr is inherited like normal, and only piped if you
request it explicitly (e.g., `2>/dev/null`). In the case of a command like
`fzf`, stderr is used for the interactive selection of files. By piping it,
something like
fzf | xargs echo
does not work. By removing all stderr piping we eliminate this issue. We can
return later with a way to deal with stderr piping when an actual use case
arises.
* added campbell theme to html colors
* updated test results. had to make change for ci.
* hopefully the last changes for this stupid test :)
* moved tests to html.rs
* remove unnecessary using statement.
* still fighting with tests and tests are winning.
* Rename `calc` to `math eval` and allow it to optionally take the expression as an argument
* Moved calc tests to math eval
Also added 2 tests and changed 1 test
* Move calc docs to math eval
* Introduce completion abstractions to nushell.
Currently, we rely on rustyline's completion structures. By abstracting this
away, we are more flexible to introduce someone elses completion engine, or our
own.
* Update value_shell.rs

command, letting the process spawning library deal with doing the appropriate
escaping.

* Use string lossy
* Run clippy
* Pin glob
* Better error messages
* Remove unneeded comment
Primarily, instead of building a parse pattern enum, we just build the regex
directly, with the appropriate capture group names so that the column name
codepaths can be shared between simple and `--regex` patterns.
Also removed capture group count compared to column name count. I don't think
this codepath can possibly be reached with the regex we now use for the
simplified capture form.

This changeset contains everything that a separate binary needs to
register its own commands (including the new help function). It is
very possible that this commit misses other pub use exports, but

* ran clippy and fixed warnings
* fix a clippy lint that was caught in pipeline
* fix dead code clippy lint for windows
* add cfg annotation to import
Both to and from without a subcommand only print the helptext. Expand the usage line a bit, so a glance at `help commands` indicates the existance of the subcommands and mentions some common formats.

* Fix: the symlink target column will only dispaly if either the `full` or `with_symlink_targets` options are given
* If the metadata for every item in the size column is None, do not show the size column
* Do not show the symlink target column if the metadata is None for all the items in the table
* fix: absolutize path against its parent if it was a symlink.
On Linux this happens because Rust calls readlink but doesn't canonicalize the resultant path.
* feat: playground function to create symlinks
* fix: use playground dirs
* feat: test for #1631, shift tests names
* Creation of FilesystemShell with custom location may fail
* Replace ichwh with which
* Creation of FilesystemShell with custom location may fail
* Replace ichwh with which
* fix: add ichwh again since it cannot be completely replaced
* fix: replace one more use of which
For example, when running the following:
crates/nu-cli/src
nushell currently parses this as an external command. Before running the command, we check to see if
it's a directory. If it is, we "auto cd" into that directory, otherwise we go through normal
external processing.
If we put a trailing slash on it though, shells typically interpret that as "user is explicitly
referencing directory". So
crates/nu-cli/src/
should not be interpreted as "run an external command". We intercept a trailing slash in the head
position of a command in a pipeline as such, and inject a `cd` internal command.

* Fix --headerless option of to-csv and to-tsv
Before to-csv --headerless split the "headerfull" output on lines,
skipped the first, and then concatenated them together. That meant
that all remaining output would be put on the same line, without
any delimiter, making it unusable. Now we replace the range of the
first line with the empty string, maintaining the rest of the
output unchanged.
* Remove extra space in indentation of to_delimited_data
* Add --separator <string> argument to to-csv
This functionaliy has been present before, but wasn't exposed
to the command.
* Refactor InputStream and affected commands.
First, making `values` private and leaning on the `Stream` implementation makes
consumes of `InputStream` less likely to have to change in the future, if we
change what an `InputStream` is internally.
Second, we're dropping `Option<InputStream>` as the input to pipelines,
internals, and externals. Instead, `InputStream.is_empty` can be used to check
for "emptiness". Empty streams are typically only ever used as the first input
to a pipeline.
* Add run_external internal command.
We want to push external commands closer to internal commands, eventually
eliminating the concept of "external" completely. This means we can consolidate
a couple of things:
- Variable evaluation (for example, `$it`, `$nu`, alias vars)
- Behaviour of whole stream vs per-item external execution
It should also make it easier for us to start introducing argument signatures
for external commands,

* Better explained
1. Fixed a bug where `--all` wasn't showing files at the root directories.
2. More use of `Result`'s `map` and `map_err` methods.
3. Making tables be homogeneous so one can, for example, `get directories`.
Previously, if the user didn't have the appropriate permissions to execute the
binary/script, they would see "command not found", which is confusing.
This commit eliminates the `which` crate in favour of `ichwh`, which deals
better with permissions by not dealing with them at all! This is closer to the
behaviour of `which` in many shells. Permission checks are then left up to the
caller to deal with.
Mostly, making more use of `map` and `map_err` in `Result`. One benefit
is that at least one location had duplicated logic for how to map the
error, which is no longer the case after this commit.
An interruptible stream can query an `AtomicBool. If that bool is true,
the stream will no longer produce any values.
Also introducing the `Interruptible` trait, which extends any `Stream`
with the `interruptible` function, to simplify the construction and
allow chaining.

* Show error message when given empty table
This makes the `binaries` function respect the `CARGO_TARGET_DIR` environment variable when set. If it's not present it falls back to the regular target directory used by Cargo.
* Fix '/' and '..' not being valid mv targets
If `/` or `../` is specified as the destination for `mv`, it will fail with an error message saying it's not a valid destination. This fixes it to account for the fact that `Path::file_name` return `None` when the file name evaluates to `/` or `..`. It will only take the slow(er) path if `Path::file_name` returns `None` in its initial check.

The extra newline character makes it hard to use nu as part of an
external processing pipeline, since the extra character could taint the
results. For example:
```
$ nu -c 'echo test | xxd'
00000000: 7465 7374 test
```
versus
```
nu -c 'echo test' | xxd
00000000: 7465 7374 0a test.
```

This improves incremental build time when working on what was previously
the root package. For example, previously all plugins would be rebuilt
with a change to `src/commands/classified/external.rs`, but now only
`nu-cli` will have to be rebuilt (and anything that depends on it).
In particular, one thing that we can't (properly) do before this commit
is consuming an infinite input stream. For example:
```
yes | grep y | head -n10
```
will give 10 "y"s in most shells, but blocks indefinitely in nu. This PR
resolves that by doing blocking I/O in threads, and reducing the `await`
calls we currently have in our pipeline code.

* Upgrade futures, async-stream, and futures_codec
These were the last three dependencies on futures-preview. `nu` itself
is now fully dependent on `futures@0.3`, as opposed to `futures-preview`
alpha.
Because the update to `futures` from `0.3.0-alpha.19` to `0.3.0` removed
the `Stream` implementation of `VecDeque` ([changelog][changelog]), most
commands that convert a `VecDeque` to an `OutputStream` broke and had to
be fixed.
The current solution is to now convert `VecDeque`s to a `Stream` via
`futures::stream::iter`. However, it may be useful for `futures` to
create an `IntoStream` trait, implemented on the `std::collections` (or
really any `IntoIterator`). If something like this happends, it may be
worthwhile to update the trait implementations on `OutputStream` and
refactor these commands again.
While upgrading `futures_codec`, we remove a custom implementation of
`LinesCodec`, as one has been added to the library. There's also a small
refactor to make the stream output more idiomatic.

Restructure and streamline token expansion
The purpose of this commit is to streamline the token expansion code, by
removing aspects of the code that are no longer relevant, removing
pointless duplication, and eliminating the need to pass the same
arguments to `expand_syntax`.
The first big-picture change in this commit is that instead of a handful
of `expand_` functions, which take a TokensIterator and ExpandContext, a
smaller number of methods on the `TokensIterator` do the same job.
The second big-picture change in this commit is fully eliminating the
coloring traits, making coloring a responsibility of the base expansion
implementations. This also means that the coloring tracer is merged into
the expansion tracer, so you can follow a single expansion and see how
the expansion process produced colored tokens.
One side effect of this change is that the expander itself is marginally
more error-correcting. The error correction works by switching from
structured expansion to `BackoffColoringMode` when an unexpected token
is found, which guarantees that all spans of the source are colored, but
may not be the most optimal error recovery strategy.
That said, because `BackoffColoringMode` only extends as far as a
closing delimiter (`)`, `]`, `}`) or pipe (`|`), it does result in
fairly granular correction strategy.
The current code still produces an `Err` (plus a complete list of
colored shapes) from the parsing process if any errors are encountered,
but this could easily be addressed now that the underlying expansion is
error-correcting.
This commit also colors any spans that are syntax errors in red, and
causes the parser to include some additional information about what
tokens were expected at any given point where an error was encountered,
so that completions and hinting could be more robust in the future.

This commit changes the way we shell out externals when using the `"$it"` argument. Also pipes per row to an external's stdin if no `"$it"` argument is present for external commands.
Further separation of logic (preparing the external's command arguments, getting the data for piping, emitting values, spawning processes) will give us a better idea for lower level details regarding external commands until we can find the right abstractions for making them more generic and unify within the pipeline calling logic of Nu internal's and external's.
