Move most of the peculiar argument handling for external calls into the parser (#13089)
# Description We've had a lot of different issues and PRs related to arg handling with externals since the rewrite of `run-external` in #12921: - #12950 - #12955 - #13000 - #13001 - #13021 - #13027 - #13028 - #13073 Many of these are caused by the argument handling of external calls and `run-external` being very special and involving the parser handing quoted strings over to `run-external` so that it knows whether to expand tildes and globs and so on. This is really unusual and also makes it harder to use `run-external`, and also harder to understand it (and probably is part of the reason why it was rewritten in the first place). This PR moves a lot more of that work over to the parser, so that by the time `run-external` gets it, it's dealing with much more normal Nushell values. In particular: - Unquoted strings are handled as globs with no expand - The unescaped-but-quoted handling of strings was removed, and the parser constructs normal looking strings instead, removing internal quotes so that `run-external` doesn't have to do it - Bare word interpolation is now supported and expansion is done in this case - Expressions typed as `Glob` containing `Expr::StringInterpolation` now produce `Value::Glob` instead, with the quoted status from the expr passed through so we know if it was a bare word - Bare word interpolation for values typed as `glob` now possible, but not implemented - Because expansion is now triggered by `Value::Glob(_, false)` instead of looking at the expr, externals now support glob types # User-Facing Changes - Bare word interpolation works for external command options, and otherwise embedded in other strings: ```nushell ^echo --foo=(2 + 2) # prints --foo=4 ^echo -foo=$"(2 + 2)" # prints -foo=4 ^echo foo="(2 + 2)" # prints (no interpolation!) foo=(2 + 2) ^echo foo,(2 + 2),bar # prints foo,4,bar ``` - Bare word interpolation expands for external command head/args: ```nushell let name = "exa" ~/.cargo/bin/($name) # this works, and expands the tilde ^$"~/.cargo/bin/($name)" # this doesn't expand the tilde ^echo ~/($name)/* # this glob is expanded ^echo $"~/($name)/*" # this isn't expanded ``` - Ndots are now supported for the head of an external command (`^.../foo` works) - Glob values are now supported for head/args of an external command, and expanded appropriately: ```nushell ^("~/.cargo/bin/exa" | into glob) # the tilde is expanded ^echo ("*.txt" | into glob) # this glob is expanded ``` - `run-external` now works more like any other command, without expecting a special call convention for its args: ```nushell run-external echo "'foo'" # before PR: 'foo' # after PR: foo run-external echo "*.txt" # before PR: (glob is expanded) # after PR: *.txt ``` # Tests + Formatting Lots of tests added and cleaned up. Some tests that weren't active on Windows changed to use `nu --testbin cococo` so that they can work. Added a test for Linux only to make sure tilde expansion of commands works, because changing `HOME` there causes `~` to reliably change. - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting - [ ] release notes: make sure to mention the new syntaxes that are supported
