Advanced commands in task completion

[tmeijn]

Hi, today I tried to make the preset:python a bit more fancy to learn a bit about tasks and argument completion.

When trying to have autocomplete on the python version I ran into the following error:

mise run preDEBUG ARGS: mise tasks --usage
DEBUG config: ~/.config/mise/config.toml
DEBUG read_to_string: "/home/tmeijn/.config/mise/tasks/preset/python"
DEBUG failed to parse task file with usage: Failed to parse KDL document

task file:

#!/usr/bin/env bash
#MISE dir="{{cwd}}"
#USAGE arg "<version>" help="Python version to use"
#USAGE complete "version" run="mise ls-remote python | grep -oP '^\d+\.\d+\.\d+$' | sort -r"

mise use python@$usage_version
mise use pre-commit
mise config set env._.python.venv.path .venv
mise config set env._.python.venv.create true -t bool
mise config set tasks.lint.run "pre-commit run -a"

Removing the grep part makes it work, but it only executes the command before the pipe:

mise run preset:python DEBUG ARGS: mise tasks --usage
DEBUG config: ~/.config/mise/config.toml
DEBUG read_to_string: "/home/tmeijn/.config/mise/tasks/preset/python"
DEBUG ARGS: mise ls-remote python

Partial task file:

#!/usr/bin/env bash
#MISE dir="{{cwd}}"
#USAGE arg "<version>" help="Python version to use"
#USAGE complete "version" run="mise ls-remote python | sort -r"

Trying to escape the | with \, produces the same error: DEBUG failed to parse task file with usage: Failed to parse KDL document

Is this known or is there some other way I could make this work?

I think it's the backslashes, try using a literal maybe:

#USAGE complete "version" run=#"mise ls-remote python | grep -oP '^\d+\.\d+\.\d+$' | sort -r"#

it'd be nice if there was a live kdl editor that showed how kdl gets parsed to test kdl in isolation but I don't think such a site exists

I need to look into https://github.com/kdl-org/vscode-kdl and see if we can reuse some of the code to add syntax highlighting for usage kdl syntax

That works @jdx, thanks! Note: sort-r doesn't work, I guess usage already sorts the output? 🤔 Or is it the shell completion... 🤔 ? Anyway, not really important.

I can't remember off-hand but I think sorting might depend on the shell
