# Description
* I was dismayed to discover recently that UnsupportedInput and
TypeMismatch are used *extremely* inconsistently across the codebase.
UnsupportedInput is sometimes used for input type-checks (as per the
name!!), but *also* used for argument type-checks. TypeMismatch is also
used for both.
I thus devised the following standard: input type-checking *only* uses
UnsupportedInput, and argument type-checking *only* uses TypeMismatch.
Moreover, to differentiate them, UnsupportedInput now has *two* error
arrows (spans), one pointing at the command and the other at the input
origin, while TypeMismatch only has the one (because the command should
always be nearby)
* In order to apply that standard, a very large number of
UnsupportedInput uses were changed so that the input's span could be
retrieved and delivered to it.
* Additionally, I noticed many places where **errors are not propagated
correctly**: there are lots of `match` sites which take a Value::Error,
then throw it away and replace it with a new Value::Error with
less/misleading information (such as reporting the error as an
"incorrect type"). I believe that the earliest errors are the most
important, and should always be propagated where possible.
* Also, to standardise one broad subset of UnsupportedInput error
messages, who all used slightly different wordings of "expected
`<type>`, got `<type>`", I created OnlySupportsThisInputType as a
variant of it.
* Finally, a bunch of error sites that had "repeated spans" - i.e. where
an error expected two spans, but `call.head` was given for both - were
fixed to use different spans.

This PR changes `to text` so that when given a `ListStream`, it streams
the incoming values instead of collecting them all first.
The easiest way to observe/verify this PR is to convert a list to a very
slow `ListStream` with `each`:
```bash
ls | get name | each {|n| sleep 1sec; $n} | to text
```
The `to text` output will appear 1 item at a time.
# Description

# Description
Currently, `filesize_format`/`filesize_metric` conflicts are resolved as
follows: if the `filesize_format` ends in "ib", then that overrides
`filesize_metric`, otherwise, `filesize_metric` overrides
`filesize_format`. This removes this difficult-to-predict asymmetric
behaviour, and makes it so that `filesize_metric` always overrides
`filesize_format`.
This also adds tests for `$env.config.filesize.format` and
`$env.config.filesize.metric` values.
REMINDER: `filesize_metric` means "increments of 1000", and refers to
KB-MB-GB-TB etc.

`proptest` caught a failing test condition for `&&` as a literal string. It requires a quotation to be parsed correctly by current `from nuon`
https://github.com/nushell/nushell/actions/runs/3753242377/jobs/6376308675
The change in the parser that now returns an error was introduced by https://github.com/nushell/nushell/pull/7241
This in theory doesn't have to be an error (it is a diagnostic for nushell code) but it is probably better safe than sorry to require quotation here.
- Add a test for `&&` in `to nuon` from proptest fail
- Fix `to nuon` generating invalid `&&` literal
- Add a test for `,` in `to nuon`/`from nuon` cycle
- Bonus: should already be properly quoted
`table` handles slow `ListStream`s in a special way: every 100 items, it
checks whether 1 second has elapsed since the last table page, and if so
it outputs a new page with all the items in its buffer.
**I would like to remove the "every 100 items" condition and always
output whatever we have if a second has elapsed.** I think this will be
a better user experience for very slow streams.
As a motivating example, imagine tailing a log file and doing some
string parsing/projection on each line. The user will be really annoyed
if they have to wait for 100 lines to be written to the log before
seeing new results!
I did some quick performance measurements with Criterion, and the
elapsed-time check takes about 16ns on my machine (Linux, 12900k). I
think the performance impact of checking that for every item will be
negligible.

> I'm not sure how i feel about that. I mean if there are a lot of
columns, it should probably have a max width so 1 column doesn't take
the entire width of your screen. Ideally it would work closely like
table worked before we migrated to tabled, as far as how column widths
were allocated.
I believe it still not completely matched.
*To be honest I am not against the #7446 approach.
The PR makes a switch between logics on a premise of `termwidth`.
So if `termwidth > 120` we start prioritizing amount of columns we can
show (We try to show as many columns as we can).
Otherwise we do what I've described in #7446 (We show the least columns
but with least truncation involvement).
In case it's OK,
I guess we could make the value configurable.

A few small tweaks to the new `explore` command:
1. Rewrote the help text a bit.
1. I think it's important to mention `:try` up front.
2. Removed the info about `:help foo` because it's currently supported
by very few subcommands
2. Make `exit_esc` default to true. I want to avoid people getting stuck
in `explore` like they get stuck in Vim
3. ~~Always show the help message ("For help type :help") on startup~~
1. The message is small+unobtrusive and I don't this is worth a
configuration item
4. Exit the information view when Escape is pressed
5. General typo+grammar cleanup

eliminate non-record rows; I think that was an unintentional and
undesirable side-effect.

# Description
Closes#6909. You can now add closures to your `color_config` themes.
Whenever a value would be printed with `table`, the closure is run with
the value piped-in. The closure must return either a {fg,bg,attr} record
or a color name (`'light_red'` etc.). This returned style is used to
colour the value.
This is entirely backwards-compatible with existing config.nu files.
Example code excerpt:
```
let my_theme = {
header: green_bold
bool: { if $in { 'light_cyan' } else { 'light_red' } }
int: purple_bold
filesize: { |e| if $e == 0b { 'gray' } else if $e < 1mb { 'purple_bold' } else { 'cyan_bold' } }
duration: purple_bold
date: { (date now) - $in | if $in > 1wk { 'cyan_bold' } else if $in > 1day { 'green_bold' } else { 'yellow_bold' } }
range: yellow_bold
string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } }
nothing: white
```
Example output with this in effect:
Slightly important notes:
* Some color_config names, namely "separator", "empty" and "hints", pipe
in `null` instead of a value.
* Currently, doing anything non-trivial inside a closure has an
understandably big perf hit. I currently do not actually recommend
something like `string: { if $in =~ '^#\w{6}$' { $in } else { 'white' }
}` for serious work, mainly because of the abundance of string-type data
in the world. Nevertheless, lesser-used types like "date" and "duration"
work well with this.
* I had to do some reorganisation in order to make it possible to call
`eval_block()` that late in table rendering. I invented a new struct
called "StyleComputer" which holds the engine_state and stack of the
initial `table` command (implicit or explicit).
* StyleComputer has a `compute()` method which takes a color_config name
and a nu value, and always returns the correct Style, so you don't have
to worry about A) the color_config value was set at all, B) whether it
was set to a closure or not, or C) which default style to use in those
cases.
* Currently, errors encountered during execution of the closures are
thrown in the garbage. Any other ideas are welcome. (Nonetheless, errors
result in a huge perf hit when they are encountered. I think what should
be done is to assume something terrible happened to the user's config
and invalidate the StyleComputer for that `table` run, thus causing
subsequent output to just be Style::default().)
* More thorough tests are forthcoming - ran into some difficulty using
`nu!` to take an alternative config, and for some reason `let-env config
=` statements don't seem to work inside `nu!` pipelines(???)
* The default config.nu has not been updated to make use of this yet. Do
tell if you think I should incorporate that into this.

`echo` tends to confuse new Nu users; they expect it to work like
`print` when it just passes a value to the next stage of the pipeline.
We haven't quite figured out what to do about `echo` in the long run,
but I think a good start is to remove `echo` from command examples where
it would be unnecessary and arguably unidiomatic.

## Fix `nu-path` usage in `nu!` testing macro
The `nu-path` crate needs to be properly re-exported so the generated
code is valid if `nu-path` is not present among the dependencies of the
using crate.
Usage of crates in `macro_rules!` macros has to follow the
`$crate::symbol_in_crate` path pattern (With an absolute path-spec also
for macros defined in submodules)
## Move `nu-test-support` to devdeps in `nu-protocol`
Also remove the now unnecessary direct dependency on `nu-path`.
`nu!` macro had to be changed to make it a proper transitive dependency.
I've been working on streaming and pipeline interruption lately. It was
bothering me that checking ctrl+c (something we want to do often) always
requires a bunch of boilerplate like:
```rust
use std::sync::atomic::Ordering;
if let Some(ctrlc) = &engine_state.ctrlc {
if ctrlc.load(Ordering::SeqCst) {
...
```
I added a helper method to cut that down to:
```rust
if nu_utils::ctrl_c::was_pressed(&engine_state.ctrlc) {
...
```

A partial fix for #7477. `uniq` can be slow sometimes, so we should
check `ctrl-c` when it's running.
Tested on [this

I ran `open yield-curve-rates-1990-2021.csv | uniq` and confirmed that I
can now cancel the operation.
Future work is needed to figure out why `uniq` is so slow.

end[^1]. This problem was uncovered and exacerbated by the new
`display_output` hook which implicitly piped _everything_ to `table`.
## The Fix
`PagingTableCreator` now adds a newline to each page instead of relying
on later code to do it.
## Tests
I spent a while trying to write a regression test for this behaviour but
I couldn't get the test to fail before my fix! I think the test
infrastructure does something special with newlines when it's checking
command output. I eventually ran out of steam trying to investigate
that, sorry.
[^1]: unless the pipe to table was the implicit one that's done when
there is no `display_output` hook set. That situation was still working
OK.
Change in `mkdir` `-s` flag to `-v` to be similar to other commands
# Description
Other commands like `rm`, `mv`, `cp` have a `-v` (`--verbose`) flag.
`mkdir` has a `-s` (`--show-created-paths`), but should be consistent
with other commands.
# User-Facing Changes
- flag `-s` replaced by `-v` in `mkdir` command.

Reverts nushell/nushell#7448
Some surprising behavior in how we do this. For example:
```
〉if (true || false) { print "yes!" } else { print "no!" }
no!
〉if (true or false) { print "yes!" } else { print "no!" }
yes!
```
This means for folks who are using the old `||`, they possibly get the
wrong answer once they upgrade. I don't think we can ship with that as
it will catch too many people by surprise and just make it easier to
write buggy code.
Closes#7431. In a nutshell:
- `run_hook_block()` in repl.rs was collecting all input into a `Value`
instead of handling streaming input properly
- this was a problem because now we have a default `display_output` hook
that _everything_ gets piped to
- this PR fixes the problem by tweaking `run_hook_block()` to return a
`PipelineData` instead of a `Value`
After this change, individual pages are rendered as they finish. This is
a little easier to see if I tweak `STREAM_PAGE_SIZE` in table.rs to 10:

## About change
In `eval_block`, all pipelines(or called statements?) result will be
printed except the last one, the last one is returned by `eval_block`
function.
So if we want to print the last statement in eval block, we just need to
print that value.

# Description
This PR changes some commands that previously accepted row conditions
(like `$it > 5`) as parameter to accept closures instead. The reasons
are:
a) The commands would need to move into parser keywords in the future
while they feel more like commands to be implemented in Nushell code as
a part of standard library.
b) In scripts, it is useful to store the predicate condition in a
variable which you can't do with row conditions.
c) These commands are not used that often to benefit enough from the
shorter row condition syntax
# User-Facing Changes
The following commands now accept **closure** instead of a **row
condition**:
- `take until`
- `take while`
- `skip until`
- `skip while`
- `any`
- `all`
This is a part of an effort to move away from shape-directed parsing.

# Description
This PR moves the `where` command to a parser keyword. While it still
uses the shape-directed parsing dictated by the signature, we're free to
change the parsing code now to a custom one once we remove the syntax
shapes.
As a side effect, the `where -b` flag was removed and its functionality
has moved to the new `filter` command.
Just FYI, other commands that take row conditions:
- `take until`
- `take while`
- `skip until`
- `skip while`
- `any`
- `all`
We can either move these to the parser as well or make them accept a
closure instead of row condition.

Make split row works more like python or rust, especially, when the
input string stars/ends with separator, append a empty string to result.
Here are examples:
python:
```python
In [6]: "\nasdf\nghi\n".split("\n")
Out[6]: ['', 'asdf', 'ghi', '']
```
rust:
```rust
fn main() {
let x = "\nabc\ndef\n";
let y = x.split("\n").collect::<Vec<&str>>();
println!("{:?}", y); // outputs: ["", "abc", "def", ""]
}

# Description
Closes#7059. Rather than generate a new Record each time $env.config is
accessed (as described in that issue), instead `$env.config = ` now A)
parses the input record, then B) un-parses it into a clean Record with
only the valid values, and stores that as an env-var. The reasoning for
this is that I believe `config_to_nu_record()` (the method that performs
step B) will be useful in later PRs. (See below)
As a result, this also "fixes" the following "bug":
```
〉$env.config = 'butts'
$env.config is not a record
〉$env.config
butts
```
~~Instead, `$env.config = 'butts'` now turns `$env.config` into the
default (not the default config.nu, but `Config::default()`, which
notably has empty keybindings, color_config, menus and hooks vecs).~~
This doesn't attempt to fix#7110. cc @Kangaxx-0

# Description
While perusing Value.rs, I noticed the `Value::int()`, `Value::float()`,
`Value::boolean()` and `Value::string()` constructors, which seem
designed to make it easier to construct various Values, but which aren't
used often at all in the codebase. So, using a few find-replaces
regexes, I increased their usage. This reduces overall LOC because
structures like this:
```
Value::Int {
val: a,
span: head
}
```
are changed into
```
Value::int(a, head)
```
and are respected as such by the project's formatter.
There are little readability concerns because the second argument to all
of these is `span`, and it's almost always extremely obvious which is
the span at every callsite.

Adds new command `math log` that takes as a required positional argument
a base.
Specialized for `math log 2` and `math log 10` for better performance
and precision that matches the expectations there. This leads to
discontinuities in numerical error but should make a better trade-off
for common usecases.

# Description
Fixes#5424. Checking the code, apparently this was always supposed to
work; however, because it compared the `Suggestion`s directly, and
internal commands had descriptions while external commands did not, it
never did function properly.

This is a stop-gap fix until we remove type-directed parsing. With this,
you can create a `OneOf` shape that can be one of a list of syntax
shapes. This gives you a little more control than you get with `Any`,
allowing you to add `Block` without breaking other parsing rules.

# Description
Closes#7110. ~~Note that unlike "real" `mut` vars, $env can be deeply
mutated via stuff like `$env.PYTHON_IO_ENCODING = utf8` or
`$env.config.history.max_size = 2000`. So, it's a slightly awkward
special case, arguably justifiable because of what $env represents (the
environment variables of your system, which is essentially "outside"
normal Nushell regulations).~~
EDIT: Now allows all `mut` vars to be deeply mutated using `=`, on
request.

This change makes SQLite queries (`open foo.db`, `open foo.db | query db
"select ..."`) cancellable using `ctrl+c`. Previously they were not
cancellable, which made it unpleasant to accidentally open a very large
database or run an unexpectedly slow query!
UX-wise there's not too much to show:
## Notes
I was hoping to make SQLite queries streamable as part of this work, but
I ran into 2 problems:
1. `rusqlite` lifetimes are nightmarishly complex and they make it hard
to create a `ListStream` iterator
2. The functions on Nu's `CustomValue` trait return `Value` not
`PipelineData` and so `CustomValue` implementations can't stream data
AFAICT.

This PR changes the `schema` command for viewing the schema of a SQLite
database file. It removes 1 level of nesting (intended to handle
multiple databases in the same connection) that I believe is
unnecessary.
### Before
### After
## Rationale
A SQLite database connection can technically be associated with multiple
non-temporary databases using [the ATTACH DATABASE
command](https://www.sqlite.org/lang_attach.html). But it's not possible
to do that _in the context of Nushell_, and so I believe that there is
no benefit to displaying the schema as if there could be multiple
databases.
I initially raised this concern back in April, but we decided to keep
the database nesting because at the time we were still looking into more
generalized database functionality (i.e. not just SQLite). I believe
that rationale no longer applies.
Also, the existing code would not have worked correctly even if a
connection had multiple databases; for every database, it was looking up
tables without filtering them by database:
6295b20545/crates/nu-command/src/database/values/sqlite.rs (L104-L118)
## Future Work
I'd like to add information on views+triggers to the `schema` output.
I'm also working on making it possible to `ctrl+c` reading from a
database (which is turning into a massive yak shave).
# Description
This PR adds the ability to easily specific background colors using the
ansi command. It also allows you to use attributes.
I also updated the grid output to be clear that the output includes an
escape character, represented here by `\e`.
# User-Facing Changes

The motivation for this stems from #6431 where I've seen crashes due to
invalid slice indexing.

Darren noticed that `open /dev/random` could not be interrupted by
`ctrl+c`. Thankfully the solution was very simple; it looks like we just
forgot to check `ctrlc` in the `impl Iterator for RawStream`!
To reproduce this, just run `open /dev/random` and then cancel it with
`ctrl+c`.

* `$env.config.explore_config` renamed to `$env.config.explore`. This
follows the principle that config subrecords relating to single commands

`$env.config.explore` out of the "legacy options" section (which is
slated for removal in a later version).

# Description
The `where -b` flag was broken. The following now works:
```
let cond = {|x| $x.name !~ 'foo'}; ls | where -b $cond
```
This is just a quick fix. Ultimately, the `where` command shouldn't need
the flag and `where $cond` should work. The first step, however, is to
move `where` away from shape-directed parsing and make it a parser

# Description
This is one of many commands that needs the `input_output_types()` part
of the signature filled in so that `$nu.scope.commands` shows the
signature properly which leads to the documentation being updated
properly.
TIL that when commands like `cal` don't have Example tests that can
easily be expressed and require the use of `None` results that we need
to use this as part of the signature.

This upgrades the `windows` and `trash` crates so we are only compiling
1 version of the `windows` crate ([I recently upgraded the version used
in `trash`](https://github.com/Byron/trash-rs/pull/58)).
I was hoping that this would lead to some decent compile time
improvements, but unfortunately it did not. Compiling 1 version of
`windows` with all the features unified is about as slow as compiling 2
versions with distinct feature sets. Still, might as well upgrade.

Also, while not strictly considered an operator, i added `not` to avoid
some confusion.

We already have the binary `bit-xor` and the shortcircuiting logical
`or`(`||`) and `and`(`&&`).
This introduces `xor` as a compact form for both brevity and clarity.
You can express the operation through `not`/`and`/`or` with a slight
risk of introducing bugs through typos.
Operator precedence
`and` > `xor` > `or`
Added logic and precedence tests.

# Description
This PR is a response to the issues raised in
https://github.com/nushell/nushell/pull/7087. It consists of two
changes:
* `export-env`, when evaluated in `overlay use`, will see the original
environment. Previously, it would see the environment from previous
overlay activation.
* Added a new `--reload` flag that reloads the overlay. Custom
definitions will be kept but the original definitions and environment
will be reloaded.
This enables a pattern when an overlay is supposed to shadow an existing
environment variable, such as `PROMPT_COMMAND`, but `overlay use` would
keep loading the value from the first activation. You can easily test it
by defining a module
```
module prompt {
export-env {
let-env PROMPT_COMMAND = (date now | into string)
}
}
```
Calling `overlay use prompt` for the first time changes the prompt to
the current time, however, subsequent calls of `overlay use` won't
change the time. That's because overlays, once activated, store their
state so they can be hidden and restored at later time. To force-reload
the environment, use the new flag: Calling `overlay use --reload prompt`
repeatedly now updates the prompt with the current time each time.
# User-Facing Changes
* When calling `overlay use`, if the module has an `export-env` block,
the block will see the environment as it is _before_ the overlay is
activated. Previously, it was _after_.
* A new `overlay use --reload` flag.

# Description
This adds `break`, `continue`, `return`, and `loop`.
* `break` - breaks out a loop
* `continue` - continues a loop at the next iteration
* `return` - early return from a function call
* `loop` - loop forever (until the loop hits a break)
Examples:
```
for i in 1..10 {
if $i == 5 {
continue
}
print $i
}
```
```
for i in 1..10 {
if $i == 5 {
break
}
print $i
}
```
```
def foo [x] {
if true {
return 2
}
$x
}
foo 100
```
```
loop { print "hello, forever" }
```
```

A small follow-up to #7221. This changes the `catch` block from a block
to a closure, so that it can access the error returned from the `try`
block. This helps with a common scenario: "the `try` block failed, and I
want to log why it failed."
### Example
### Future Work
Nu's closure syntax is a little awkward here; it might be nicer to allow
something like `catch err { print $err }`. We discussed this on Discord
and it will require special parser code similar to what's already done
for `for`.
I'm not feeling confident enough in my parser knowledge to make that
change; I will spend some more time looking at the `for` code but I
doubt I will be able to implement anything in the next few days.
Volunteers welcome.
# Description
This adds `try` (with an optional `catch` piece). Much like other
languages, `try` will try to run a block. If the block fails to run
successfully, the optional `catch` block will run if it is available.

This adds the `try` command.

This PR closses issue #7155, where now providing a non valid color will
just ignore it and use the default.
Making the same changes as the original issue just starts nushell

# Description
While trying to add a new `uniq-by` command I refactored the `uniq`
command code to understand it and try to reuse. I think this is more
compact and easier to understand.
The part that I think it's a little confusing in this refactor is the
conditions inside `.filters()`, for example: `!flag_show_repeated ||
(value.1 > 1)`. I could use `if (flag_show_repeated) {value.1 > 1} else
{true}` but it is more verbose, what do you think?
PS: Not sure if you like this kind of PR, sorry if not.
# Tests + Formatting
I also added a test where the `uniq` has a table as input.

# Description
As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.
And if the command is executed directly like: `cat tmp`, the result
won't change.
Fixes: #6816Fixes: #3980
Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.
If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

Following up on #7180 with some feature cleanup:
- Move the `database` feature from `plugin` to `default`
- Rename the `database` feature to `sqlite`
- Remove `--features=extra` from a lot of scripts etc.
- No need to specify this, the `extra` feature is now the same as the
default feature set
- Remove the now-redundant 2nd Ubuntu test run
# Description
Support for this breaking change was raised in #7191. This affects
`sort`, `sort-by`, `str contains` and `find`. `--ignore-case` is used by
a few POSIX programs such as `less` and `grep`, as well as a few other
popular utils like `tree` and `wget`. Since long names aren't especially
popular (existing primarily for self-documentation purposes), I consider
this on the shallow end of the compat-break scale.
Note that the `-i` short flag is not affected.

This adds new pipeline connectors called out> and err> which redirect either stdout or stderr to a file. You can also use out+err> (or err+out>) to redirect both streams into a file.
Currently `last n` memory use is O(input), while it should be O(n). This
patch replaces code collecting all of last's input into a Vec<_> with
collecting into a bounded VecDeque<_>. UI/UX remain are unchanged.
Alters `all`, `any`, `each while`, `each`, `insert`, `par-each`, `reduce`, `update`, `upsert` and `where`,
so that their blocks take an optional parameter containing the index.
* Make json require string and pass around metadata
The json deserializer was accepting any inputs by coercing non-strings
into strings. As an example, if the input was `[1, 2]` the coercion
would turn into `[12]` and deserialize as a list containing number
twelve instead of a list of two numbers, one and two. This could lead
to silent data corruption.
Aside from that pipeline metadata wasn't passed aroud.
This commit fixes the type issue by adding a strict conversion
function that errors if the input type is not a string or external
stream. It then uses this function instead of the original
`collect_string()`. In addition, this function returns the pipeline
metadata so it can be passed along.
* Make other formats require string
The problem with json coercing non-string types to string was present in
all other text formats. This reuses the `collect_string_strict` function
to fix them.
* `IntoPipelineData` cleanup
The method `into_pipeline_data_with_metadata` can now be conveniently
used.
* add signature information when help on one command
* tell user that one command support operated on cell paths
Also, make type output to be more friendly, like `record<>` should just be `record`

This adds support for (limited) mutable variables. Mutable variables are created with mut much the same way immutable variables are made with let.
Mutable variables allow mutation via the assignment operator (=).
❯ mut x = 100
❯ $x = 200
❯ print $x
200
Mutable variables are limited in that they're only tended to be used in the local code block. Trying to capture a local variable will result in an error:
❯ mut x = 123; {|| $x }
Error: nu::parser::expected_keyword (link)
× Capture of mutable variable.
The intent of this limitation is to reduce some of the issues with mutable variables in general: namely they make code that's harder to reason about. By reducing the scope that a mutable variable can be used it, we can help create local reasoning about them.
Mutation can occur with fields as well, as in this case:
❯ mut y = {abc: 123}
❯ $y.abc = 456
❯ $y
On a historical note: mutable variables are something that we resisted for quite a long time, leaning as much as we could on the functional style of pipelines and dataflow. That said, we've watched folks struggle to work with reduce as an approximation for patterns that would be trivial to express with local mutation. With that in mind, we're leaning towards the happy path.

* Bump nushell-sytem dep to ntapi 0.4
0.3.7 trigger a warning about code being incompatible
with future rust versions. This is resolved in 0.4
https://github.com/MSxDOS/ntapi/issues/11

* make format filesize more flexible
* make code simpler
* finish refactor on bytes commands
* finish refactor on str commands
* fimplify code
* rename from column_paths to cell_paths
* fix: ✨ "saner" default for mv
fixes#6747
As highlighted in the issue, the default behavior of nu currently
is to overwrite the destination file without notice.
This is not a "standard" expectation users that want this behavior
can create a dedicated alias.
* fix: 📝 edit the comment
* fix: ✨ updated the tests
* fix: 🚧 use --force for case test
* Remove unused dependencies
Inspired by #6938 ran `cargo +nightly udeps --features extra`.
Removes 2 crates and should remove an unnecessary intra-workspace
dependency which might open up further opportunities for compilation.
* Make windows-only dependency conditional in toml
`omnipath` is only used on Windows and already behind a `#[cfg]` block
in the code. Made the dependency in `Cargo.toml` conditional as well.
* Make `nu-pretty-hex` example a proper example
This allows making `rand` a dev-dependency in this crate.
This reduces the number of dependencies to build for `cargo build` or
`cargo run` by around 19.
Will not speed up CI as we need to `cargo test` but should help for
`cargo install` or users just building from source.
Time saved on my machine ~0.8 secs so likely unnoticable in noise.
Larger future goal is reducing longer dependency chains to allow more
parallel compilation.
Avoids compiling the crate twice due to incompatible versions from
dependencies. This avoids binary bloat before linking as well.
Narrow our feature selection to the used modules/functions to save
compile time. On my machine reduces `nix` crate compile time from
around 9 secs to 0.9 secs.
Fixes#6895
Warning: `Iterator::map_while` does not return a `FusedIterator`!
Depending on the consuming adaptor or code (e.g. for loop) the iteration
may be stopped but this is not guaranteed.
Adds a test example but Examples handle iterators like
`FusedIterator` and thus don't catch the regression
Cleanup the message on another test
Disable backtrace on miette
- gimli crate requires several seconds
Disable diagnostics on wax
- depends on an outdated miette version
Builds fine, no observable loss in diagnostics quality of life
Removes 10 crates that have to be compiled.
* Remove unnecessary `#[allow]` annots
Reduce the number of lint exceptions that are not necessary with the
current state of the code (or more recent toolchain)
* Remove dead code from `FileStructure` in nu-command
* Replace `allow(unused)` with relevant feature switch
* Deal with `needless_collect` with annotations
* Change hack for needless_collect in `from json`
This change obviates the need for `allow(needless_collect)`
Removes a pessimistic allocation for empty strings, but increases
allocation size to `Value`
Probably not really worth it.
* Revert "Deal with `needless_collect` with annotations"
This reverts commit 05aca98445.
The previous state seems to better from a performance perspective as a
`Vec<String>` is lighter weight than `Vec<Value>`
* Wrap `open` parse errors from `from` commands
Minimal fix for #6843
This propagates the underlying errors from the called `from` commands
and adds a top-level error with the full path and the understood file
extension and resulting called command.
* Repoint inner span for `from ...` to `open`
* Add actionable message: refer to help or use --raw
* Add support to render right prompt on last line of the prompt
* reset reedline to main branch
* update reedline to fix right prompt to be rendered correctly
* reset reedline to main branch again
* Make Tab insert (partial) completion instead of select next menu item

* Reorder conditional deps for readability
* Pull reedline from the most recent main branch
* Map 'Submit' and 'SubmitOrNewline' events

* Filter out empty glob patterns
An empty argument to the "glob" command will now produce an empty result.
Working towards nushell/nushell#6653.
* Run `cargo fmt --all`
Just autoformatted the repo so that CI passes and we have a consistent code
format across modules.
* Treat empty glob argument as error
The glob command will now report an empty string argument as an error instead
of silently ignoring it.
See https://github.com/nushell/nushell/pull/6707#discussion_r993345013.
* Add tests for glob command
Two small tests for the glob command, one to check that the empty string errors
it, and another to sanity check the '*' glob, have been added.
* Rename glob sanity check star test

* fix issue 6602 (broken highlighting in find)
Find uses highlight_search_string to see where the string was found. The problem was that the style would just "append" to the existing haystack (including the ANSI escape codes of LS_COLORS).
This first strips the ANSI escape codes out of the haystack before formatting the
output string.

- We can reserve `?` syntax for any other nushell feature.

This PR merges all the completions tests into one file.

This allows for parallel test excecution.

`rstest = 0.12` added support for asynchronous timeouts during testing
thus requiring a larger set of dependencies. Since `rstest = 0.14` this
can be disabled if not used.
Should keep build times for local or CI tests in check.
The test was reading the operating system error message which is
dependent on the system locale.
Just test for the `(os error 2)` errorcode instead.
This should support both
unixoid systems and Windows in more locales.

I am not sure if this was correct and I am breaking it or if it was a

reuse spans and what should recreate new ones?
But yeah it felt weird that the Value's Span was being ignored since in

we can't really guess the format
- It calls `register` with format and plugin path

* Gate all plugin tests behind feature = "plugin" instead of one by one
* Remove format!-like behavior from nu_with_plugins
nu_with_plugins had format!-like behavior where it would allow calls
such as this:
```rs
nu_with_plugins!(
cwd: "dir/",
"open {} | get {}",
"Cargo.toml",
"package.version"
)
```
And although nifty it seems to have never been used before and the same
can be achieved with a format! like so:
```rs
nu_with_plugins!(
cwd: "dir/",
format!("open {} | get {}", "Cargo.toml", "package.version")
)
```
So I am removing it to keep the complexity of the macro in check

* Add plugin CLI argument
While working on supporting CustomValues in Plugins I stumbled upon the
test utilities defined in [nu-test-support][nu-test-support]
and thought these will come in handy, but they end up being outdated.
They haven't been used or since engine-q's was merged, so they are
currently using the old way engine-q handled plugins, where it would
just look into a specific folder for plugins and call them without
signatures or registration. While fixing that I realized that there is
currently no way to tell nushell to load and save signatures into a
specific path, and so those integration tests could end up potentially
conflicting with each other and with the local plugins the person
running them is using.
So this adds a new CLI argument to specify where to store and load
plugin signatures from
I am not super sure of the way I implemented this, mainly
I was a bit confused about the distinction between
[src/config_files.rs][src/config_files.rs] and
[crates/nu-cli/src/config_files.rs][crates/nu-cli/src/config_files.rs].
Should I be moving the plugin loading function from the `nu-cli` one to
the root one?

- Refactors code a bit and extends tests for encodings
- `decode base64` returns a binary `Value` (that may be decoded into a string using `decode` command)
* feat: add `--binary(-b)` flag to `decode base64`
Default output type is now string, but binary can be requested using this new flag.
* fixes the issue for 'open' and other commands that explicitly use `SyntaxShape::Filepath`
* fixes for `rm` and similar commands
* fixes for `ls`: potentially breaking?
* fmt
* a curious fix to the test
* a curious fix to the test, except for Windows this time

This PR adds support for an SQLite history via nushell/reedline#401
The SQLite history is enabled by setting history_file_format: "sqlite" in config.nu.
* somewhat working sqlite history
* Hook up history command
* Fix error in SQlitebacked with empty lines
When entering an empty line there previously was the "No command run"
error with `SqliteBackedHistory` during addition of the metadata
May be considered a temporary fix

Release notes: https://github.com/nushell/reedline/releases/tag/v0.6.0
This release contains several bug fixes and improvements to the vi-emulation and documentation.
- Improvements to the vi-style keybindings (@sadmac7000):
- `w` now correctly moves to the beginning of the word.
- `e` to move to the end of the word.
- Bugfixes:
- Support terminal emulators that erroneously report a size of 0x0 by assuming a default size to avoid panics and draw nevertheless (@DhruvDh)
- Fix `ListMenu` layout calculations. Avoids scrolling bug when wrapping occurs due to the line numbering (@ahkrr)
- Avoid allocating to the total history capacity which can cause the application to go out of memory (@sholderbach)
- Documentation improvements including addition of documentation intended for reedline developers (@petrisch, @sholderbach)
Schema `0o[77]` with the same padding behavior as the other binary literals
- this updates #5551
- test for parsing binary from octal
- test for string parsing

Changes to reedline since `v0.4.0`:
- vi normal mode `I` for inserting at line beginning
- `InsertNewline` edit command that can be bound to `Alt-Enter` if
desired to have line breaks without relying on the `Validator`
- `ClearScreen` will directly clear the visible screen. `Signal::CtrlL` has been
removed.
- `ClearScrollback` will clear the screen and scrollback. Can be used to
mimic macOS `Cmd-K` screen clearing. Helps with #5089
* nu-cli: added tests for file completions
* test adding extra sort
* Feature/refactor completion options (#5228)
* Copy completion filter to custom completions
* Remove filter function from completer
This function was a no-op for FileCompletion and CommandCompletion.
Flag- and VariableCompletion just filters with `starts_with` which
happens in both completers anyway and should therefore also be a no-op.
The remaining use case in CustomCompletion was moved into the
CustomCompletion source file.
Filtering should probably happen immediately while fetching completions
to avoid unnecessary memory allocations.
* Add get_sort_by() to Completer trait
* Remove CompletionOptions from Completer::fetch()
* Fix clippy lints
* Apply Completer changes to DotNuCompletion
* add os to $nu based on rust's understanding (#5243)
* add os to $nu based on rust's understanding

Prior to this change we would recover the names for known
externals by looking up the span in the engine state. This would fail
when using an alias for two reasons:
1. In cases where we don't have a subcommand, like this:
```
>>> extern bat [filename: string]
>>> alias b = bat
>>> bat some_file
'b' is not recognized as an internal or external command,
operable program or batch file.
```
The problem is that after alias expansion, we replace the span of the
expanded name with the original alias (this is done to alleviate
non-related issues). The span contents we look up therefore contain `b`,
the alias, instead of the expanded command name.
2. In cases where there's a subcommand:
```
>>> alias g = git
>>> g push
thread 'main' panicked at 'internal error: span missing in file contents cache', crates\nu-protocol\src\engine\engine_state.rs:474:9
note: run with `RUST_BACKTRACE=1` environment variable to display a
backtrace
```
In this case, the span in call starts where the expansion for the `g`
alias is defined and end after `push` on the last command entered. This
is not a proper span and causes a panic when we try to look it up. Note
that this is the case for all expanded aliases that involve a
subcommand, but we never actually try to retrieve the contents for that
span in other cases.
Anyway, the new way of looking up the name is arguably cleaner
regardless of the issues mentioned above. But it's nice that it fixes
them too.

This commit renders ANSI chars in order to provide shell integrations
such Kitty's opening feature that captures the output of the last
command in a pager such as less.
Fixes#5138
- With a change to reedline hints can now be hidden. This is useful when
no ANSI coloring is available as hints become indistinguishable from the
actual buffer
- remove commented out code
- order the logging calls according to the implementation
I don't personally agree with this; I'd prefer less magic,
and not expanding _anything_ except `~` as an initial path element

To remove a default keybinding for a particular edit mode, set the `event: null`:
e.g. to disable screen clearing with Ctrl-L

event: null
} ]}

* Include license text in all crates
Three crates already have license texts, so I'm keeping them, but

system and not Windows.
Also bump the copyright year to end in 2022.

* remove commas from default file
* added error message
* Remove panic from BlockCommands run function
Instead of panicing, the run method now returns an error to prevent
nushell from unexpected termination.
* Add ability to open command to run with blocks
The open command tries to parse the content of the file
if there is a command called 'from (file ending)'. This works
fine if the command was 'built in' because the run method doesn't
fail in this case. It did fail on a BlockCommand, though.
This change will first probe if the command contains a block and
evaluate it, if this is the case. If there is no block, it will run
the command the same way as before.
* Add test open files with BlockCommands
* Update open.rs
* Adjust file type on open with BlockCommand parser

Enables the use of some features on reedline
- Keeping the line when clearing the screen with `Ctrl-L`
- Using the internal cut buffer between lines
- Submitting external commands via keybinding and keeping the line
Additional effect:
Keep the history around and do basic syncs (performance improvement
minimal as session changes have to be read and written)
Additional change:
Give the option to defer writing/rereading the history file to the
closing of the session ($config.sync_history_on_enter)

* Add streaming support to save for ExternalStream data
Prior to this change, save would collect data from an ExternalStream (data
originating from externals) consuming memory for the full amount of data piped
to it,
This change adds streaming support for ExternalStream allowing saving of
arbitrarily large files and bounding memory usage.
* Remove broken save test
This test passes but not for the right reasons, since this test was
written filename has become a required parameter. The parser outputs
an error but the test still passes as is checking the original un-mutated
file assuming save has re-written the contents.
This change removes the test.

* Add test for passing binary data through externals
This change adds an ignored test to confirm that binary data is passed
correctly between externals to be enabled in a later commit along with
the fix.
To assist in platform agnostic testing of binary data a couple of
additional testbins were added to allow testing on `Value::Binary` inside
`ExternalStream`.
* Support binary data to stdin of run-external
Prior to this change, any pipeline producing binary data (not detected
as string) then feed into an external would be ignored due to
run-external only supporting `Value::String` on stdin.
This change adds binary stdin support for externals allowing something
like this for example:
〉^cat /dev/urandom | ^head -c 1MiB | ^pv -b | ignore
1.00MiB
This would previously output `0.00 B [0.00 B/s]` due to the data not
being pushed to stdin at each stage.
Prior to this change, a pipeline of externals would result in high memory
usage if any of the producers in the chain, produced data faster than
the consumers.
For example a pipeline:
> fast-producer | slow-consumer
Would cause a build up of `Value::{String,Binary}`'s in the mpsc channels
between each command as values are added to the channels faster than they
are consumed, eventually OOM'ing depnding on system resources, the volume
of data and speed diff. between fast v's slow.
This change replaces the unbounded channels with bounded channels
to limit the number of values that can build up and providing
back-pressure to limit ram usage.

* Fix path when expanding tilde
Expanding tilde with no other relative paths would result in:
`$HOME/` instead of `$HOME`. This occurs when users run `cd` with
no extra arguments. In that case, the user's PWD would include the
trailing separator. This does not happen when explicitly passing
a value, such as `cd ~`, because in that case, the path would be
canonicalized.
This happens because std::path::PathBuf::push always adds a separator,
even if adding an empty path, which is what happens when `cd` is
invoked.

At the moment `crossterm` apparently has a regression decoding certain important key combinations on Windows.
Thus reedline reverted to the previous version.
Some changes are necessary to remove the need for `crossterm` in the use of `lscolors`.
Introduces two local conversion traits.
Additionally update the `Highlighter` API to support the cursor
position.
This will enable brace/statement match highlighting.
Previously, the parser tried to look up the predecl also in the
permanent state and if a definition with that name already existed, it
would try to update it, which is illegal.
* Handle string->value env conv. with env. var.
Also adds the environment variable for Path/PATH and removes it from

* Fix indentation in default config
This restores a basic version of the `post` command.
Some source types have been omitted from this first take.
I copied from `fetch` and from `post`@0.40.0.
Part of #4356
* Fix failing pipeline()
The `skip(1)` was there likely to remove the welcome message.
* Fix typo
* Fix nu! test macro to enter cwd correctly
Nushell's current working directory is determined primarily by the PWD
environment variable.
* Add `date format --list`, and make format string optional (providing default)
* Make DRY
`into datetime --list` now uses `generate_strfttime_list` from `date format --list`
* refactor strftime to use current datetime
* Fix formatting of specification descriptions
Fixes issues caused when copying directly from docs.rs
* Change default format to rfc2822
Perhaps to make it more DRY, functions from `into datetime` can be used. However, currently `into datetime` is a bit tricky to use as it needs a separate time zone argument.
* Tweak in-shell docs to match modified behavior
* Show %#z format specifier in `into datetime --list` only
* cargo fmt
* Satisfy clippy
* Add different features combinations
* Specify styles manually
* Fix args

For the width calculations for table layout the `strip_ansi` function
has to be called frequently. By checking for the ASCII control chars
(0x00 to 0x1f) except `\n` that are stripped by `strip_ansi_escapes` the number of
necessary allocations can be reduced significantly for the simple case
of text not containing ANSI escapes.
**Benchmark:**
```
nu -c "for i in 0..1000 { ls } | flatten | table"
```
**Allocation reduction**
Running on the nushell repo root as the directory, this change reduces the
allocation volume by approximately 400 MB
(Measured run via KDE heaptrack)
**Speed improvement to output**
Measured via `/usr/bin/time -v`

On top of the original merge, this one should not collect a stream

Ansi-cut expects ranges of character numbers (of the non-ansi control
sequence characters) instead of byte indices.
This fixes the panics when wrapping of non-unicode lines (which exceed
the demanded number of characters as byte indices).
Also rectifies some wrong wrapping of unicdoe containing lines that
don't panic

* Use only $nu.env.PWD for getting current directory
Because setting and reading to/from std::env changes the global state
shich is problematic if we call `cd` from multiple threads (e.g., in a
`par-each` block).
With this change, when engine-q starts, it will either inherit existing
PWD env var, or create a new one from `std::env::current_dir()`.
Otherwise, everything that needs the current directory will get it from
`$nu.env.PWD`. Each spawned external command will get its current
directory per-process which should be thread-safe.
One thing left to do is to patch nu-path for this as well since it uses
`std::env::current_dir()` in its expansions.
* Rename nu-path functions
*_with is not *_relative which should be more descriptive and frees
"with" for use in a followup commit.
* Clone stack every each iter; Fix some commands
Cloning the stack each iteration of `each` makes sure we're not reusing
PWD between iterations.
Some fixes in commands to make them use the new PWD.
* Post-rebase cleanup, fmt, clippy
* Change back _relative to _with in nu-path funcs
Didn't use the idea I had for the new "_with".

I removed the Inflector dependency in favor of heck for two reasons:
- to close#3674.
- heck seems simpler and actively maintained
We could probably alter the structure of the `str_` module to expose the
individual casing behaviors better.
I did not feel as confident on changing those signatures.
So I took a lazier approach of a macro in the `mod.rs` that creates the public
shimming function to heck's traits.

We are passing commands into a shell underneath but we were not
escaping arguments correctly. This new version of the code also takes
into consideration the ";" and "&" characters, which have special
meaning in shells.
We would probably benefit from a more robust way to join arguments to
shell programs. Python's stdlib has shlex.join, and perhaps we can
take that implementation as a reference.
* clean up escaping of posix shell args
I believe the right place to do escaping of arguments was in the
spawn_sh_command function. Note that this change prevents things like:
^echo "$(ls)"
from executing the ls command. Instead, this will just print
$(ls)
The regex has been taken from the python stdlib implementation of shlex.quote

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.

* Fixes a panic with defining two commands with the same name caused by
declaration not found after predeclaration.
* Adds a new error if a custom command is defined more than once in one
block.
* Add some tests
* Hiding logic is simplified and fixed so you can hide and unhide the
same def repeatedly.
* Separates predeclared ids into its own data structure to protect them
from hiding. Otherwise, you could hide the predeclared variable and
the actual def would panic.
* compiles on nightly now. (breaking change)
* less deps
* Switch over to new resolver
(it's been stable for a while.)

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.

* Support completion when cursor inside an argument
Bash supports completion even when cursor is in an argument, this is very useful for some fixup after the initial completion.
Let add this feature as well.

It is implemented as a preliminary check when parsing a call and relies

There were some unnecessary Cow conversions leftover from the old

* Use canonicalize in source command; Improve errors
Previously, `source` used `expand_path()` which does not follow
symlinks.
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)
```
