Moves the separate quiet variable in the `Config` struct into the existing
verbosity field; the `Verbosity` enum now has a `Quiet` variant. When running, the
presence of the quiet flag will set the verbosity to `Quiet`, overriding any
number of verbosity flags in the CLI args.
The `--choose` subcommand runs a chooser to select a recipe to run. The
chooser should read lines containing recipe names from standard input,
and write one of those names to standard output.
The chooser defaults to `fzf`, a popular fuzzy finder, but can be
overridden by setting $JUST_CHOOSER or passing `--chooser <CHOOSER>`.
- Complete variable names after `--set`
- Complete recipe names
- Display recipe signature and body below command line
- Modify completions subcommand to produce enhanced zsh completion script
Trim whitespace at beginning and end of generated completions.
Additionally, since some editors will automatically insert a final
newline into text files, make sure a final newline is present.
Add a subcommand that prints out a space-separated list of the names of
top-level variables in the justfile.
The syntax is:
$ just --variables
a b c
This can be used for any purpose, but is mostly intended for completion
scripts, so that they can get the names of variables without using
`--evaluate`.
Additionally:
- Add `bin/generate-completions` script to regenerate checked-in
completions
- Update dependencies
- Regenerate checked-in completions
Make just print clap-generated shell completion scripts with `--completions`
command. Currently, Bash, Zsh, Fish, PowerShell, and Elvish are supported.
Additionally, the generated completion scripts are checked in to the
`completions` folder.
Add the `--shell-arg` and `--clear-shell-args` flags, which allow
setting and clearing arguments to the shell from the command line.
This allows full control over the shell from the command line. Additionally,
any shell-related arguments on the command line override
`set shell := [...]` in the Justfile, which I think will be the behavior that most
people expect.
During analysis, resolve alias targets from `Name`s to `Rc<Recipe>`,
giving us type-level assurance that alias resolution was performed, and
avoiding the need to look up alias targets in a separate table when
running.
When `--init` is passed on the command line, search upward for the
project root, identified by the presence of a VCS directory like `.git`,
falling back to the current directory, and create a default justfile in
that directory.
This diff makes positional argument parsing much cleaner, along with
adding a bunch of tests. Just's positional argument parsing is rather,
complex, so hopefully this reform allows it to both be correct and stay
correct.
User-visible changes:
- `just ..` is now accepted, with the same effect as `just ../`
- `just .` is also accepted, with the same effect as `just`
- It is now an error to pass arguments or overrides to subcommands
that do not accept them, namely `--dump`, `--edit`, `--list`,
`--show`, and `--summary`. It is also an error to pass arguments to
`--evaluate`, although `--evaluate` does of course still accept
overrides.
(This is a breaking change, but hopefully worth it, as it will allow us
to add arguments to subcommands which did not previously take
them, if we so desire.)
- Subcommands which do not accept arguments may now accept a
single search-directory argument, so `just --list ../` and
`just --dump foo/` are now accepted, with the former starting the
search for the justfile to list in the parent directory, and the latter
starting the search for the justfile to dump in `foo`.
- Instead of changing the current directory with `env::set_current_dir`
to be implicitly inherited by subprocesses, we now use
`Command::current_dir` to set it explicitly. This feels much better,
since we aren't dependent on the implicit state of the process's
current directory.
- Subcommand execution is much improved.
- Added a ton of tests for config parsing, config execution, working
dir, and search dir.
- Error messages are improved. Many more will be colored.
- The Config is now onwed, instead of borrowing from the arguments and
the `clap::ArgMatches` object. This is a huge ergonomic improvement,
especially in tests, and I don't think anyone will notice.
- `--edit` now uses `$VISUAL`, `$EDITOR`, or `vim`, in that order,
matching git, which I think is what most people will expect.
- Added a cute `tmptree!{}` macro, for creating temporary directories
populated with directories and files for tests.
- Admitted that grammer is LL(k) and I don't know what `k` is.
Moves the code which executes subcommands into Subcommand:run,
delegating to separate functions for each subcommand. This reduces the
disgustingness of `run::run` a bit, and paves the way for future
refactoring and cleanup.
Move `env::set_current_dir` outside of `Config::from_matches()` and into
`run()`. It's a bit cleaner this way, and sets us up to make the just
process not change its own directory at all, instead explicitly changing
the working directory of its child processes.
- Differentiate between `arg`s, which are flags and options, and `cmd`s,
which are mutually exclusive subcommands
- Replace string literals, like "EVALUATE", with constants, like
`cmd::EVALUATE`, since they're slightly less error prone.
- Remove `Config::evaluate`, and handle it like other subcommands
run::run() is pretty unwieldy. As a first step in improving it, this
commit pulls most of the argument parsing into the `config` module.
It also renames `Configuration` to `Config`, just to be easier to type.
