Re-implement aliases (#8123) # Description This PR adds an alternative alias implementation. Old aliases still work but you need to use `old-alias` instead of `alias`. Instead of replacing spans in the original code and re-parsing, which proved to be extremely error-prone and a constant source of panics, the new implementation creates a new command that references the old command. Consider the new alias defined as `alias ll = ls -l`. The parser creates a new command called `ll` and remembers that it is actually a `ls` command called with the `-l` flag. Then, when the parser sees the `ll` command, it will translate it to `ls -l` and passes to it any parameters that were passed to the call to `ll`. It works quite similar to how known externals defined with `extern` are implemented. The new alias implementation should work the same way as the old aliases, including exporting from modules, referencing both known and unknown externals. It seems to preserve custom completions and pipeline metadata. It is quite robust in most cases but there are some rough edges (see later).

skip comments and eols while parsing pipeline (#10149) This pr - fixes https://github.com/nushell/nushell/issues/10143 - fixes https://github.com/nushell/nushell/issues/5559 # Description Current `lite_parse` does not handle multiple line comments and eols in pipeline. When parsing the following tokens: | `"abcdefg"` | ` \|` | `# foobar` | ` \n` | `split chars` | | ------------- | ------------- |------------- |------------- |------------- | | [Command] | [Pipe] | [Comment] | [Eol] | [Command] | | | | Last Token |Current Token | | `TokenContent::Eol` handler only checks if `last_token` is `Pipe` but it will be broken if there exist any other thing, e.g. extra `[Comment]` in this example. This pr make the following change: - While parsing `[Eol]`, try to find the last non-comment token as `last_token` - Comment is supposed as `[Comment]+` or `([Comment] [Eol])+` - `[Eol]+` is still parsed just like current nu (i.e. generates `nothing`). Notice that this pr is just a quick patch if more comment/eol related issue occures, `lite_parser` may need a rewrite. # User-Facing Changes Now the following pipeline works: ```bash 1 | # comment each { |it| $it + 2 } | # comment math sum ``` Comment will not end the pipeline in interactive mode: ```bash ❯ 1 | # comment (now enter multiple line mode instead of end) ▶▶ # foo ▶▶ 2 ``` # Tests + Formatting - :green_circle: `toolkit fmt` - :green_circle: `toolkit clippy` - :green_circle: `toolkit test` - :green_circle: `toolkit test stdlib` # After Submitting None --------- Co-authored-by: Horasal <horsal@horsal.dev>

Fix panic on too few arguments for custom function (#10395) # Description Old code was comparing remaining positional arguments with total number of arguments, where it should've compared remaining positional with with remaining arguments of any kind. This means that if a function was given too few arguments, `calculate_end_span` would believe that it actually had too many arguments, since after parsing the first few arguments, the number of remaining arguments needed were fewer than the *total* number of arguments, of which we had used several. Fixes #9072 Fixes: https://github.com/nushell/nushell/issues/13930 Fixes: https://github.com/nushell/nushell/issues/12069 Fixes: https://github.com/nushell/nushell/issues/8385 Extracted from #10381 ## Bonus It also improves the error handling on missing positional arguments before keywords (no longer crashing since #9851). Instead of just giving the keyword to the parser for the missing positional, we give an explicit error about a missing positional argument. I would like better descriptions than "missing var_name" though, but I'm not sure if that's available without Old error ``` Error: nu::parser::parse_mismatch × Parse mismatch during operation. ╭─[entry #1:1:1] 1 │ let = if foo · ┬ · ╰── expected valid variable name ╰──── ``` New error ``` Error: nu::parser::missing_positional × Missing required positional argument. ╭─[entry #18:1:1] 1 │ let = foo · ┬ · ╰── missing var_name ╰──── help: Usage: let <var_name> = <initial_value> ``` # User-Facing Changes The program `alias = = =` is no longer accepted by the parser

remove let-env, focus on mutating $env (#9574) # Description For years, Nushell has used `let-env` to set a single environment variable. As our work on scoping continued, we refined what it meant for a variable to be in scope using `let` but never updated how `let-env` would work.

Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> Before this change, parsing `[[[[[[[[[[[[[[[[[[[[[[` would cause nushell to consume several gigabytes of memory, now it should be linear in time. The old code first tried parsing the head of the table as a list and then after that it checked if it got more arguments. If it didn't, it throws away the previous result and tries to parse the whole thing as a list, which means we call `parse_list_expression` twice for each call to `parse_table_expression`, resulting in the exponential growth The fix is to simply check that we have all the arguments we need before parsing the head of the table, so we know that we will either call parse_list_expression only on sub-expressions or on the whole thing, never both.

Deprecate `register` and add `plugin use` (#12607) # Description Adds a new keyword, `plugin use`. Unlike `register`, this merely loads the signatures from the plugin cache file. The file is configurable with the `--plugin-config` option either to `nu` or to `plugin use` itself, just like the other `plugin` family of commands. At the REPL, one might do this to replace `register`: ```nushell > plugin add ~/.cargo/bin/nu_plugin_foo > plugin use foo ``` This will not work in a script, because `plugin use` is a keyword and `plugin add` does not evaluate at parse time (intentionally). This means we no longer run random binaries during parse. The `--plugins` option has been added to allow running `nu` with certain plugins in one step. This is used especially for the `nu_with_plugins!` test macro, but I'd imagine is generally useful. The only weird quirk is that it has to be a list, and we don't really do this for any of our other CLI args at the moment. `register` now prints a deprecation parse warning. This should fix #11923, as we now have a complete alternative to `register`. # User-Facing Changes - Add `plugin use` command - Deprecate `register` - Add `--plugins` option to `nu` to replace a common use of `register` # Tests + Formatting I think I've tested it thoroughly enough and every existing test passes.

Rewrite run_external.rs (#12921) This PR is a complete rewrite of `run_external.rs`. The main goal of the rewrite is improving readability, but it also fixes some bugs related to argument handling and the PATH variable (fixes https://github.com/nushell/nushell/issues/6011). I'll discuss some technical details to make reviewing easier. ## Argument handling Quoting arguments for external commands is hard. Like, *really* hard. We've had more than a dozen issues and PRs dedicated to quoting arguments (see Appendix) but the current implementation is still buggy. Here's a demonstration of the buggy behavior: ```nu let foo = "'bar'" ^touch $foo # This creates a file named `bar`, but it should be `'bar'` ^touch ...[ "'bar'" ] # Same ``` I'll describe how this PR deals with argument handling. First, we'll introduce the concept of **bare strings**. Bare strings are **string literals** that are either **unquoted** or **quoted by backticks** [^1]. Strings within a list literal are NOT considered bare strings, even if they are unquoted or quoted by backticks. When a bare string is used as an argument to external process, we need to perform tilde-expansion, glob-expansion, and inner-quotes-removal, in that order. "Inner-quotes-removal" means transforming from `--option="value"` into `--option=value`. ## `.bat` files and CMD built-ins On Windows, `.bat` files and `.cmd` files are considered executable, but they need `CMD.exe` as the interpreter. The Rust standard library supports running `.bat` files directly and will spawn `CMD.exe` under the hood (see [documentation](https://doc.rust-lang.org/std/process/index.html#windows-argument-splitting)). However, other extensions are not supported [^2]. Nushell also supports a selected number of CMD built-ins. The problem with CMD is that it uses a different set of quoting rules. Correctly quoting for CMD requires using [Command::raw_arg()](https://doc.rust-lang.org/std/os/windows/process/trait.CommandExt.html#tymethod.raw_arg) and manually quoting CMD special characters, on top of quoting from the Nushell side. ~~I decided that this is too complex and chose to reject special characters in CMD built-ins instead [^3].

Rewrite run_external.rs (#12921) This PR is a complete rewrite of `run_external.rs`. The main goal of the rewrite is improving readability, but it also fixes some bugs related to argument handling and the PATH variable (fixes https://github.com/nushell/nushell/issues/6011). I'll discuss some technical details to make reviewing easier. ## Argument handling Quoting arguments for external commands is hard. Like, *really* hard. We've had more than a dozen issues and PRs dedicated to quoting arguments (see Appendix) but the current implementation is still buggy. Here's a demonstration of the buggy behavior: ```nu let foo = "'bar'" ^touch $foo # This creates a file named `bar`, but it should be `'bar'` ^touch ...[ "'bar'" ] # Same ``` I'll describe how this PR deals with argument handling. First, we'll introduce the concept of **bare strings**. Bare strings are **string literals** that are either **unquoted** or **quoted by backticks** [^1]. Strings within a list literal are NOT considered bare strings, even if they are unquoted or quoted by backticks. When a bare string is used as an argument to external process, we need to perform tilde-expansion, glob-expansion, and inner-quotes-removal, in that order. "Inner-quotes-removal" means transforming from `--option="value"` into `--option=value`. ## `.bat` files and CMD built-ins On Windows, `.bat` files and `.cmd` files are considered executable, but they need `CMD.exe` as the interpreter. The Rust standard library supports running `.bat` files directly and will spawn `CMD.exe` under the hood (see [documentation](https://doc.rust-lang.org/std/process/index.html#windows-argument-splitting)). However, other extensions are not supported [^2]. Nushell also supports a selected number of CMD built-ins. The problem with CMD is that it uses a different set of quoting rules. Correctly quoting for CMD requires using [Command::raw_arg()](https://doc.rust-lang.org/std/os/windows/process/trait.CommandExt.html#tymethod.raw_arg) and manually quoting CMD special characters, on top of quoting from the Nushell side. ~~I decided that this is too complex and chose to reject special characters in CMD built-ins instead [^3]. Hopefully this will not affact real-world use cases.~~ I've implemented escaping that works reasonably well. ## `which-support` feature The `which` crate is now a hard dependency of `nu-command`, making the `which-support` feature essentially useless. The `which` crate is already a hard dependency of `nu-cli`, and we should consider removing the `which-support` feature entirely. ## Appendix Here's a list of quoting-related issues and PRs in rough chronological order. * https://github.com/nushell/nushell/issues/4609 * https://github.com/nushell/nushell/issues/4631 * https://github.com/nushell/nushell/issues/4601 * https://github.com/nushell/nushell/pull/5846 * https://github.com/nushell/nushell/issues/5978 * https://github.com/nushell/nushell/pull/6014 * https://github.com/nushell/nushell/issues/6154 * https://github.com/nushell/nushell/pull/6161 * https://github.com/nushell/nushell/issues/6399 * https://github.com/nushell/nushell/pull/6420 * https://github.com/nushell/nushell/pull/6426 * https://github.com/nushell/nushell/issues/6465 * https://github.com/nushell/nushell/issues/6559 * https://github.com/nushell/nushell/pull/6560 [^1]: The idea that backtick-quoted strings act like bare strings was introduced by Kubouch and briefly mentioned in [the language reference](https://www.nushell.sh/lang-guide/chapters/strings_and_text.html#backtick-quotes).

Improve type hovers (#9515) # Description This PR does a few things to help improve type hovers and, in the process, fixes a few outstanding issues in the type system. Here's a list of the changes: * `for` now will try to infer the type of the iteration variable based on the expression it's given. This fixes things like `for x in [1, 2, 3] { }` where `x` now properly gets the int type. * Removed old input/output type fields from the signature, focuses on the vec of signatures. Updated a bunch of dataframe commands that hadn't moved over. This helps tie things together a bit better * Fixed inference of types from subexpressions to use the last expression in the block * Fixed handling of explicit types in `let` and `mut` calls, so we now respect that as the authoritative type I also tried to add `def` input/output type inference, but unfortunately we only know the predecl types universally, which means we won't have enough information to properly know what the types of the custom commands are. # User-Facing Changes Script typechecking will get tighter in some cases Hovers should be more accurate in some cases that previously resorted to any. # Tests + Formatting <!-- Don't forget to add tests that cover your changes.

Custom command input/output types (#9690) # Description This adds input/output types to custom commands. These are input/output pairs that related an input type to an output type. For example (a single int-to-int input/output pair): ``` def foo []: int -> int { ... } ``` You can also have multiple input/output pairs: ``` def bar []: [int -> string, string -> list<string>] { ... } ``` These types are checked during definition time in the parser. If the block does not match the type, the user will get a parser error. This `:` to begin the input/output signatures should immediately follow the argument signature as shown above. The PR also improves type parsing by re-using the shape parser. The shape parser is now the canonical way to parse types/shapes in user code. This PR also splits `extern` into `extern`/`extern-wrapped` because of the parser limitation that a multi-span argument (which Signature now is) can't precede an optional argument. `extern-wrapped` now takes the required block that was previously optional. # User-Facing Changes The change to `extern` to split into `extern` and `extern-wrapped` is a breaking change. # Tests + Formatting <!-- Don't forget to add tests that cover your changes.

If the record literal is big, an error message pointing to the start of where the parser thinks things went wrong should help people fix their code. # User-Facing Changes Below are screenshots of the new errors: If there's a stray record key right before the record ends, it highlights only that key and tells the user it expected a colon after it: ![image](https://github.com/nushell/nushell/assets/45539777/94503256-8ea2-47dd-b69a-4b520c66f7b6) If the record ends before the value for the last field was given, it highlights the key and colon of that field and tells the user it expected a value after the colon: ![image](https://github.com/nushell/nushell/assets/45539777/2f3837ec-3b35-4b81-8c57-706f8056ac04) If there are two consecutive expressions without a colon between them, it highlights everything from the second expression to the end of the record and tells the user it expected a colon. I was tempted to add a help message suggesting adding a colon in between, but that may not always be the right thing to do. ![image](https://github.com/nushell/nushell/assets/45539777/1abaaaa8-1896-4909-bbb7-9a38cece5250) # Tests + Formatting # After Submitting
