Add the `--list-heading` option, to override the heading text printed
before a list, defaulting to `Available recipes:\n`, and
`--list-prefix`, to override the indentation before each list item.
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!
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`.
