Is there interest in generating fish completions? If so, I will do a thorough review and make any requested changes. See below for a TODO list and let me know what to add.

Full disclosure, I used Claude Code (Sonnet 4.5) to generate this while testing the model's capabilities and I was pleasantly surprised. Upon cursory review and testing it works.

Testing

# ensure no existing completions
llama-server --<TAB>
# nothing should appear

# generate and load on-the-fly (process substitution)
source (llama-server --completion-fish | psub)

# test
llama-server --<TAB>
# completions should appear

TODOs

• Reduce overlap with --completion-bash, i.e. list of executables
• Fix "executable list is not quite correct" noted by @slaren below
  • some of these programs don't use the common lib to parse the command line
    • like llama-bench, llama-quantize, llama-simple
  • and only the tools should need completions, not the examples
  • IIAC bash side needs fixed too?
• Compare to generated bash completions for anything that is missing
  • i.e. find out why -h<TAB> doesn't list -hf and similar single dash options
• Ensure code follows all guidelines
• Review escaping of strings
• Review complete argument generation, i.e. -s/l
• Rename bash equivalents?
  • common_params_print_completion(...) => common_params_print_completion_bash(...)
  • params.completion => params.completion_bash
• Do you want automated testing? If so please expand/shrink this list:
  • run llama-server --completion-fish and ensure zero exit code + generates output
  • optional - source it (like above) to make sure it doesn't fail
  • optional - unit tests for options/escaping logic
  • I don't see tests of --completion-bash, but would be happy to add some for it too, could do that in a separate PR too
• Suppress some (or all) of STDERR when generating? i.e. llama-server --completion-[fish/bash]?
• Generate files into ~/.cache/fish/generated_completions
  • Can I ask fish shell for location? So I don't have to replicate any logic in this repo?
  • and/or add smth like --completion-fish-path <PATH|->
  • - means STDOUT
  • make sure help notes include explanations of args
