Automatically generate a custom command-line option parser from just the long-form help text for your program.
I am happy to announce release 1.5 of optparse.
Optparse's home page is at https://github.com/gvvaughan/optparse, with documentation at https://gvvaughan.github.io/optparse.
This was the option parser I originally wrote for Specl, and later donated to lua-stdlib. Even though I’ve not yet completed the slimming down of lua-stdlib in preparation for the next release, you can continue to use optparse without installing stdlib.
This release fixes **another** long standing bug.
Install it with LuaRocks, using:
luarocks install optparse 1.5
## Noteworthy changes in release 1.5 (2022年07月30日) [stable]
### Bug fixes
- The parser no longer shadows the internal `optparse.version`
`on_handler` by also saving the last word of the parsed
`versiontext` into `optparse.version`.
But, we don't want to break existing clients that use the content
of the saved `optparse.version` string either. Since the
`on_handler` was never available to callers before due to being
shadowed, rename it to `optparse.showversion`.
### Incompatible changes
- For consistency with the renaming of `optparse.showversion`,
similarly rename `optparse.help` to `optparse.showhelp`. For
backwards compatibility, `optparse.help` continues to be available
too, but is now undocumented. Consider using the `showhelp` in
your projects, especially if you also start using `showversion`.
