Modify the lexer to keep track of opening `({[` and closing `]})` delimiters.
When the lexer would emit an eol or indent outside of a recipe when there
is at least one open delimiter, emit a whitespace token instead.
This allows expressions to be split on multiple lines, like so:
x := if 'a' == 'b' {
'x'
} else {
'y'
}
This does not work inside of recipe body interpolations, although this
restriction might relaxed in the future.
Add conditional expressions of the form:
foo := if lhs == rhs { then } else { otherwise }
`lhs`, `rhs`, `then`, and `otherwise` are all arbitrary expressions, and
can recursively include other conditionals. Conditionals short-circuit,
so the branch not taken isn't evaluated.
It is also possible to test for inequality with `==`.
Remove all manual tracking of which tokens would have been accepted by
the parser in favor of having the parser add tokens that it checks for
to a set of expected tokens, clearing them when it accepts a token, and
using the current contents of the set in error messages.
This is a massive improvement, and will make the parser easier to
modify going forward.
And, this actually solves my sole issue with hand-written parsers.
Thanks to matklad on reddit for suggesting this!
Modifies the bash completion script to complete both recipes and flags.
`just <TAB>` will complete recipes, and `just -<TAB>` will complete
flags and options.
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>`.
Combine all integration test binaries into a single binary with the root
in `tests/lib.rs`. This also turns of automatic test discovery, so
when adding another set of integration tests, a mod statement will need
to be added to `tests/lib.rs`.
If an environment variable exists with the same key as a variable from a
`.env` file, skip the variable from the `.env` file in favor fo the key
from the environment.
On Windows, skip conversion if a shebang path does not include `/`. In
this case it is not a Unix path, and does not need to be converted to a
Windows path before running.
Add a `examples` directory, for holding example justfiles, along
with an example justfile, `examples/pre-commit.just`, that shows
ideas for using just with `pre-commit`.
