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.
* Add 'expor env' dummy command
* (WIP) Abstract away module exportables as Overlay
* Switch to Overlays for use/hide
Works for decls only right now.
* Fix passing import patterns of hide to eval
* Simplify use/hide of decls
* Add ImportPattern as Expr; Add use env eval
Still no parsing of "export env" so I can't test it yet.
* Refactor export parsing; Add InternalError
* Add env var export and activation; Misc changes
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
* Fix eval not recognizing hidden decls
Without this change, calling `hide foo`, the evaluator does not know
whether a custom command named "foo" was hidden during parsing,
therefore, it is not possible to reliably throw an error about the "foo"
name not found.
* Add use/hide/export env var tests; Cleanup; Notes
* Ignore hide env related tests for now
* Fix main branch merge mess
* Fixed multi-word export def
* Fix hiding tests on Windows
* Remove env var hiding for now
* 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
* Change path join signature
* Appending now works without flag
* Column path operation is behind a -c flag
* Move column path arg retrieval to a function
Also improves errors
* Fix path join tests
* Propagate column path changes to all path commands
* Update path command examples with columns paths
* Modernize path command examples by removing "echo"
* Improve structured path error message
* Fix typo
* Expand path when converting value -> PathBuf
Also includes Tagged<PathBuf>.
Fixes#3605
* Expand path for PATH env. variable
Fixes#1834
* Remove leftover Cows after nu-path refactor
There were some unnecessary Cow conversions leftover from the old
nu-path implementation.
* 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.
* Resolve rebase artifacts
* Remove leftover dependencies on removed feature
* Remove unnecessary 'pub'
* Start taking notes and fooling around
* Split canonicalize to two versions; Add TODOs
One that takes `relative_to` and one that doesn't.
More TODO notes.
* Merge absolutize to and rename resolve_dots
* Add custom absolutize fn and use it in path expand
* Convert a couple of dunce::canonicalize to ours
* Update nu-path description
* Replace all canonicalize with nu-path version
* Remove leftover dunce dependencies
* Fix broken autocd with trailing slash
Trailing slash is preserved *only* in paths that do not contain "." or
"..". This should be fixed in the future to cover all paths but for now
it at least covers basic cases.
* Use dunce::canonicalize for canonicalizing
* Alow cd recovery from non-existent cwd
* Disable removed canonicalize functionality tests
Remove unused import
* Break down nu-path into separate modules
* Remove unused public imports
* Remove abundant cow mapping
* Fix clippy warning
* Reformulate old canonicalize tests to expand_path
They wouldn't work with the new canonicalize.
* Canonicalize also ~ and ndots; Unify path joining
Also, add doc comments in nu_path::expansions.
* Add comment
* Avoid expanding ndots if path is not valid UTF-8
With this change, no lossy path->string conversion should happen in the
nu-path crate.

* Add trim trailing slashes tests
* Update nu-path dependency
* Remove unused import
* Regenerate lockfile
* 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] {...}`.

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.
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
* 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
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
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)`).
* 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.
* Removes arg serialization
* action stream -> output stream
* uses nu_protocol::Range instead of NumericRange
* random missing newline I found in the code
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

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!
* 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)
