Moves platform specific functionality into its own module.
Thanks to @Meralis40 for starting this!
This also gets just building on windows \^_^/
Although a lot of tests still fail (✖╭╮✖)
The `PlatformInterface` trait contains functions which abstract
over platform specific functionality, with implementations for
different platforms behind #[cfg(*)] attributes.
- `make_shebang_command()` constructs a command which will execute
the given script as if by a shebang. On linux this executes the
file, on windows it runs the interpreter directly.
- `set_execute_permission()` sets the execute permission on a
file. This is a nop on windows, since all files are executable.
- `signal_from_exit_status()` extracts the signal a process was
halted by from its exit status, if it was halted by a signal.
Mostly for debugging purposes, so I can make sure behavior is
consistent across different shells. Although I suppose this might
also be of use if you've got a mega weird `sh` that you'd like to
avoid.
Defaults to `sh` so current behavior is preserved.
If the first argument to just contains a `/`, then it will be handled
specially. Everything before the last `/` is treated as a directory, and
just will search for the justfile starting there, instead of in the
current directory.
Causes all recipe lines to be printed, regardless of --quiet or `@`.
Prints the name of each recipe before running it. Hopefully useful for
diagnosing problems.
An invocation like `just foo=bar` would lead to no recipe being run due
to the way that override arguments were being processed.
Fix that and add a test that covers that case.
If a `#...` comment appears on the line immediately before a recipe, it
is considered to be a doc comment for that recipe.
Doc comments will be printed when recipes are `--list`ed or `--dump`ed.
Also adds some color to the `--list`ing.
Fixes#84
Already implemented Display for Justfile, so no reason not to expose it
to the user.
Also only allow one of --list, --dump, or --show, since they don't make
a lot of sense together.
This is a pretty gross commit, since it also includes a lot of
unrelated refactoring, especially of how error messages are printed.
Also adds a lint recipe that prints lines over 100 characters
To test, I added a `--color=[auto|always|never]` option that defaults to
auto in normal use, but can be forced to `always` for testing. In `auto`
mode it defers to `atty` to figure out if the current stream is a
terminal and uses color if so.
Color printing is controlled by the `alternate` formatting flag.
When printing an error message, using `{:#}` will print it with colors
and `{}` will print it normally.
