Now working on converting git-annex to use
|
|
[optparse-applicative](https://github.com/pcapriotti/optparse-applicative)
|
|
for its command line parsing. I've wanted to do this for a long time,
|
|
because the current code for options is generally horrible, runs in
|
|
IO, and is not at all type safe, while optparse-applicative has wonderful
|
|
composable parsers and lets each subcommand have its own data type
|
|
repesenting all its options.
|
|
|
|
What pushed me over the edge is that optparse-applicative has automatic
|
|
bash completion!
|
|
|
|
# source <(git-annex --bash-completion-script `which git-annex`)
|
|
# git-annex fsck -
|
|
--all --key -S
|
|
--from --more -U
|
|
|
|
Since nobody has managed to write a full bash completion for git-annex
|
|
before, let alone keep it up-to-date with changes to the code, automating
|
|
the problem away is a really nice win. :)
|
|
|
|
The conversion is a rather huge undertaking; the diff is already over 3000
|
|
lines large after 8 hours of work, and I'm maybe 1/3rd done, with
|
|
the groundwork laid (except for global options still todo) and a few
|
|
subcommands converted. This won't land for this week's release; it'll
|
|
need a lot of testing before it'll be ready for any release.
