Supply non-constant arguments to dynamic variable

Hello I want to use charm/gum with task. I.e. I want to download binary if it not exist and use it with custom arguments. Something like this, but that piece is not valid config. What should I do?

version: "3"
silent: true
vars:
  DIR: cache
  GUM:
    sh: go run github.com/charmbracelet/gum@latest {{.ARGS}}
tasks:
  clean:
    cmds:
      - |
        {{.GUM}} confirm "Clean?" && rm -rf {{.DIR}}

version: "3"
silent: true
vars:
  DIR: cache
  GUM:
    sh: go run github.com/charmbracelet/gum@latest {{.ARGS}}
tasks:
  clean:
    cmds:
      - |
        {{.GUM}} confirm "Clean?" && rm -rf {{.DIR}}

Hello ! Something like that should work :

version: "3"
silent: true
vars:
  DIR: cache
  GUM: go run github.com/charmbracelet/gum@latest
tasks:
  clean:
    cmds:
      - '{{.GUM}} confirm "Clean?" && rm -rf {{.DIR}}'

version: "3"
silent: true
vars:
  DIR: cache
  GUM: go run github.com/charmbracelet/gum@latest
tasks:
  clean:
    cmds:
      - '{{.GUM}} confirm "Clean?" && rm -rf {{.DIR}}'

Oh, so all I was need is to make variable static...

vmaerten•12mo ago

Yes 🙂 cmd in cmds are executed after being remplaced by the template engine

Btw, can we also ignore error code printing from task? I know we had issue for reworking --silent flag, but maybe there are workarounds?

You can use ignore_error: true For example:

version: "3"
silent: true
vars:
  DIR: cache
  GUM: go run github.com/charmbracelet/gum@latest
tasks:
  clean:
    ignore_error: true
    cmds:
      - '{{.GUM}} confirm "Clean?" && rm -rf {{.DIR}}'

version: "3"
silent: true
vars:
  DIR: cache
  GUM: go run github.com/charmbracelet/gum@latest
tasks:
  clean:
    ignore_error: true
    cmds:
      - '{{.GUM}} confirm "Clean?" && rm -rf {{.DIR}}'

The first one is with silent: true The second with silent: false

But it will still print the exit status, right?

Yes AFAIK, there is nothing to hide commands' output in Task You may need play with redirect stdout and stderr
