Complete parameters of tasks

[mrdgo]

Is your feature request related to a problem? Please describe.

Usually, I run nur run. I set all globally sensible defaults in the nurfile and all local defaults in .nur/env.nu. But whenever I want a single invocation to use different parameters, I have to 1. memorize which ones it takes and 2. what type of argument it accepts. My main entry point got a bit messy:

def "nur run" [
  --test-case (-t): path@"nu-complete test" = "EMPTY" # Path to project to split
  --run-wrapper (-w) # whether to (re-)run this wrapper
  --run-split (-s) # whether to run `split`
  --build-enclaves (-e) # run make in $project
  --run-final-app (-a) # run final compartmentalized app
  --clone-artifact (-c) # only clone artifact to ssgx1
  --abstract (-A) # debugging only: run abstract lint
  --run-policy (-p) # run policy, otherwise requires one in schemata/*
  --collect-bounds (-l) # construct a call graph
  --in-gitlab-ci # then don't run -e in docker
  --server-dir-suffix (-S): string = ""
  --policy: string = "limitations-driven"
  --schema: path@"nu-complete path" = "EMPTY"
  --call-graph: path@"nu-complete path" = "EMPTY"
  --project: path@"nu-complete path" = "EMPTY"
  --target-dir: path@"nu-complete path" = "App"
  --skip-clean (-C)
] {
  ...
}

As you can see, I already tried to implement completions for certain parameters:

def "nu-complete path" [
  prefix: string
] {
  let word = $prefix | split row -r '\s+' | last
  glob $"($word)*" | path relative-to $env.PWD
}

def "nu-complete test" [prefix: string] {
  let word = $prefix | split row -r '\s+' | last
  glob $"tests/($word)*" | path relative-to $"($env.PWD)/tests"
}

But sadly, neither can nu complete the parameter names, nor their arguments.

Describe the solution you'd like

(I feel like this might be difficult to pull off, but)
I'd really enjoy being able to just type nur run --<tab> and get completion options. The same way, when I selected an option, I want to hit tab again and get the desired nu-complete completions.

Describe alternatives you've considered

I tried the aforementioned nu-complete syntax from vanilla nu.

Oh, wow, those are really a lot of parameters. There are the nur completion scripts in https://github.com/nur-taskrunner/nur/tree/main/scripts, but those are mainly meant to have auto-completion on the task name - so this won't help here.

I will look into this. It might be possible that nur needs to have the ability to be registered as a nu plugin (see #3) to get this kind of dynamic completion (I'm not sure to be frank). The issue otherwise might be that the completion of external commands in nu is meant for static sets of arguments. Like ls behaves the same in every instance. nur has context and the arguments depend heavily on which task you run, which is not predefined. But let me look into this, not sure yet :)
