Fixes#5593 (OOM introduced with #5587 when no config was present and an attempt was
made to allocate all memory in advance)
Includes also other changes to reedline:
- Vi word definition fixed and `w` and `e` work as expected
* only set cwd for child process if cwd exists, and avoid showing error when pwd is not exists
* better comment text

Currently the fully fledged help menu is bound to `Ctrl-Q`.
Help is widely associated with `F1`.
Before merging check that it is passed through on all platforms and
terminal emulators
* Change history menu keybinding to ctrl+r from ctrl+x
* Remove menupage actions from default config

* Updating formatting
* Removed commented out code for readability
* Fixed compile error on merge
* Add Nushell REPL simulator; Fix bug in overlay add
The `nu_repl` function takes an array of strings and processes them as
if they were REPL lines entered one by one. This helps to discover bugs
due to the state changes between the parse and eval stages.

same overlays, or the command will fail.
* Add merging on overlay remove
* Change help message and comment
* Add some remove-merge/discard tests
* (WIP) Track removed overlays properly
* Clippy; Fmt

* Add two more overlay tests
* Add ModuleId to OverlayFrame
* Fix env conversion accidentally activating overlay
It activated overlay from permanent state prematurely which would
cause `overlay add` to misbehave.
* Remove unused parameter; Add overlay list test
* Remove added traces
* Add overlay commands examples
* Modify TODO
* Fix $nu.scope iteration
* Disallow removing default overlay
* Refactor some parser errors
* Remove last overlay if no argument
* Diversify overlay examples
* Make it possible to update overlay's module
In case the origin module updates, the overlay add loads the new module,
makes it overlay's origin and applies the changes. Before, it was
impossible to update the overlay if the module changed.

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)

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
To remove a default keybinding for a particular edit mode, set the `event: null`:
e.g. to disable screen clearing with Ctrl-L
```
let $config = {keybindings: [{
modifier: control
keycode: char_l
mode: [emacs, vi_normal, vi_insert]
event: null
} ]}
```

* Include license text in all crates
Three crates already have license texts, so I'm keeping them, but
symlinking the `LICENSE` from the top level to the rest of the crate
directories. This works as long as `cargo publish` is done on a Unix-y
system and not Windows.
Also bump the copyright year to end in 2022.

* list of menus in config
* default value for menu
* menu from block
* generic menus examples
* change to reedline git path

* added error message
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)
* nu-completer with suggestions
* help menu with scrolling
* updates description rows based on space
* configuration for help menu
* update nu-ansi-term
* corrected test for update cells
* changed keybinding
* Refactor usage of is_perf_true to be a parameter passed around
* Move repl loop and command/script execution to nu_cli
* Move config setup out of nu_cli
* Update config_files.rs
* Update main.rs

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.
* 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
* (WIP) Fix dataframe tests
* (WIP) Fix missing args after rebase
* (WIP) Clone only env vars, not the whole stack
* (WIP) Add env var clone to `for` loop as well
* Minor edits
* Refactor merge_delta() to include stack merging.
Less error-prone than doing it manually.
* Clone env for each `update` command iteration
* Mark env var hidden only when found in eng. state
* Fix clippt warnings
* Add TODO about env var reading
* Do not clone empty environment in loops
* Remove extra cwd collection
* Split current_dir() into str and path; Fix autocd
* Make completions respect PWD env var
* Proof of concept treating env vars as Values
* Refactor env var collection and method name
* Remove unnecessary pub
* Move env translations into a new file
* Fix LS_COLORS to support any Value
* Fix spans during env var translation
* Add span to env var in cd
* Improve error diagnostics
* Fix non-string env vars failing string conversion
* Make PROMPT_COMMAND a Block instead of String
* Record host env vars to a fake file
This will give spans to env vars that would otherwise be without one.
Makes errors less confusing.
* Add 'env' command to list env vars
It will list also their values translated to strings
* Sort env command by name; Add env var type
* Remove obsolete test
* 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.
Seems we do `ctrl` feature checks in `nu-cli` and `nu-command`. We should find a better way to report the enabled features un the `version` command without using the conditionals (or somewhere else)
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
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.
* 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
With the current code it is possible to attach custom commands from
a custom binary, but only for interactive mode. This change makes
it possible to also customize the evaluation context for commands
and scripts.
* Use ctx.configs in all config commands
* Remove all setting/accessing of vars.("config-path")
* Add tests
* Add comment
* Reload cfg on remove
* Hypocratic ws change
* Use history_path in hist_or_default
* Make clippy happy
* Fix rebase stuff
* Fix clippy lint
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.
* Revert "History, more test coverage improvements, and refactorings. (#3217)"
This reverts commit 8fc8fc89aa.
* Add tests
* Refactor .nu-env
* Change logic of Config write to logic of read()
* Fix reload always appends to old vars
* Fix reload always takes last_modified of global config
* Add reload_config in evaluation context
* Reload config after writing to it in cfg set / cfg set_into
* Add --no-history to cli options
* Use --no-history in tests
* Add comment about maybe_print_errors
* Get ctrl_exit var from context.global_config
* Use context.global_config in command "config"
* Add Readme in engine how env vars are now handled
* Update docs from autoenv command
* Move history_path from engine to nu_data
* Move load history out of if
* No let before return
* Add import for indexmap
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.
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)

* Update Cargo.toml
Extend the optional features to nu-command
Co-authored-by: Jonathan Turner <jonathandturner@users.noreply.github.com>
* 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
───┬──────┬──────────────────────────┬─────────
# │ arg │ path │ builtin

/home/leo/repos/nushell(fix/which_reports_wrong_usage)> echo

/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.
