refactor(cmdline): improve option completion

[soifou]

• Option info is now cached on first lookup instead of fetched every time.
• Shortname is shown in the label description for options.
• Fixed accepting option references (like echo &shiftwidth) in completions.

LGTM

[soifou]

I don't like this condition but only all fail while retrieving the provided options. And I'm not fund either by using pcall to guard against eventually an unhandled case... thought?

[Saghen]

I'm not opposed to the guard, but would be good to document why that's the case

[soifou]

Ok I'll add a note.

Also did a quick bench between vim.opt[name].get() and vim.api.nvim_get_option_info2 and the tradeoff is negligeable.

[soifou]

Merged, thanks for the quick review!

Side note: I just realized that the refactor commits do not appear in the changelog. Is this intentional? If so, I'll keep it in mind.

[Saghen]

Ah yeah, that's a side effect of using the conventional changelog. I ought to document (or automate really) how I do releases but basically I do:

NEW_VERSION=v1.4.1
git tag $NEW_VERSION -s -m $NEW_VERSION

nix-shell -p nodePackages_latest.conventional-changelog-cli # could grab via npx/bunx instead
conventional-changelog -o CHANGELOG.md --release-count 0 -p conventionalcommits

# Open the CHANGELOG.md and grab the latest release, discard the changes in git and paste the new release
# Update flake.nix

git tag -d $NEW_VERSION
git commit -m "chore: bump version to $NEW_VERSION"
git tag $NEW_VERSION -s -m $NEW_VERSION

# Update docs website
cd doc
npm run build:releas
bunx wrangler pages deploy .vitepress/dist --project-name=blink-cmp --branch=main

# Wait for CI to finish and copy from CHANGELOG.md to release notes
