* Add example test to zip
* Port merge command from Nushell
On top of the original merge, this one should not collect a stream
returned from the merged block and allows merging records.
* Switch to short-names when the path is a relative_path (a dir) and exit with an error if the path does not exist
* Remove debugging print line
* Show relative filenames... It does not work yet for ls ../
* Try something else to fix relative paths... it works, but the ../ code part is not very pretty

* Make env var eval order during "use" deterministic
Fixes#726.
* Merge delta after getting config
To make sure env vars are all in the engine state and not in the stack.
* 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".
* Remove leftover current_dir from rebase
* Add cwd sync at merge_delta()
This makes sure the parser and completer always have up-to-date cwd.
* Always pass absolute path to glob in ls
* Do not allow PWD a relative path; Allow recovery
Makes it possible to recover PWD by proceeding with the REPL cycle.
* Clone stack in each also for byte/string stream
* (WIP) Start moving env variables to engine state
* (WIP) Move env vars to engine state (ugly)
Quick and dirty code.
* (WIP) Remove unused mut and args; Fmt

It's no longer attached to a Block. Makes access to overlays more
streamlined by removing this one indirection. Also makes it easier to
create standalone overlays without a block which might come in handy.

* Switch to Overlays for use/hide
Works for decls only right now.

Now it is possible to `use` env var that was exported from a module.
This commit also adds some new errors and other small changes.
* Add env var hiding

Added tests for from eml
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.
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.)
* let's leave num-format for another PR
* Allow different names for ...rest
* Resolves#3945

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.

* plugin: basic from_mp4 implementation
This patch introduces a very basic implementation of from_mp4, with only
a few bits of meta-data available. The rest of the available meta-data
(which is more than half left), will be included in a later patch
* Mp4: Almost all track metadata is implemented
Only meta-data that is not implemented is duration, facing some weird
issue I am going to check on later
* Mp4: All meta-data fields implemented
All meta-data fields that can be retrieved are now retrieved, with the
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

* plugins: Add plugin extra to src/plugins
* Mp4: Replace unwrap() with expect()

* 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.
* 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()

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)
* 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
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.
* 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).
* Fix rustfmt
* Update lock

* Pick ...or_insert_dependency functions into pieces
Previously there was get_shape_of_expr_or_insert dependency, now there is
get_shape_of_expr and get_shape_of_expr_or_insert_dependency
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.
* Change Expression::Variable(Variable::It(...)) to Expression::Variable(...)

* Clarify comment

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
* Ignore failing tests
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.

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 `..<`
* remove unused dependencies

* Forgot the tests!
* Updated primitive.rs to match changes.
* Updated where example to match changes.
* And the html test!
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
