[feature] Add a "flag-per-file" token #2260
Description
Is your feature request related to a problem? Please describe.
Many command line tools will accept multiple configuration/ignore files by passing multiple files, one flag per.
prettier --ignore-path /.gitignore --ignore-path /.prettierignore --ignore-path project-specific-ignore ...
Describe the solution you'd like
It would be great to be able to use a token to just have the thing expand automatically.
fileGroups:
prettier-ignore:
# Global ignores in the root
- '/.gitignore'
- '/.prettierignore'
# Project specific ignores
- '.prettierignore'
- '.gitignore'
tasks:
format:
command:
- prettier
- --config
- '$workspaceRoot/.prettierrc'
- '@groupFlag("--ignore-path ", prettier-ignore)
The task would expand to:
tasks:
format:
command:
- prettier
- --config
- '~/home/workspace/.prettierrc'
- '--ignore-path'
- '/.gitignore'
- '--ignore-path'
- '/.prettierignore'
# and more `ignore-path` flags as needed for every file foundThis would also allow individual projects to override the fileGroup and add/remove arguments to the command.
Describe alternatives you've considered
An alternative would be to provide a facility in Pkl that allows you to cycle through the found files. That does ad a barrier to adoption (and if the facility already exists to do it that way, it wasn't immediately obvious)
