Question & Feature Request: How to build all sub packages?

[lqhuang]

Env setup

pdm-example-monorepo: a6b3f47
pdm: 2.5.3
python: 3.10
OS: macOS 13.3.1

Problem

1. Fail to setup in project root

$ pdm install

The saved Python interpreter doesn't match the project's requirement. Trying to find another one.
python.use_venv is on, creating a virtualenv for this project...
Virtualenv is created successfully at /Users/lqhuang/Src/pdm-example-monorepo/.venv
See /var/folders/9n/q2xsxp9x1l79r6rvgl_9h4sw0000gn/T/pdm-install-resolve-42si7wtx.log for detailed debug log.

Add '-v' to see the detailed traceback

2. No alias to build specific sub packages or all defined sub-packages ?

$ pdm build pkg-core
Usage: pdm [-h] [-V] [-c CONFIG] [-v] [-I] [--pep582 [SHELL]]
           {add,build,cache,completion,config,export,fix,import,info,init,install,list,lock,publish,remove,run,search,self,plugin,show,sync,update,use,venv} ...
pdm: error: unrecognized arguments: pkg-core 

If run pdm build directly under root project, pdm will info us current pyproject.toml is broken or missing essential metadata.

$ pdm build

Building packages by -p path option works well.

$ pdm build -p ./packages/pkg-core

What I expect?

1. Could we add an option like --all to easily build all sub packages?
2. (Optional) Using project alias or name (pdm build -n pkg-core) instead of path (-p) to build sub packages

Thanks for your efforts!

Best wishes,

Yes, this requires the interface change which is planned in pdm-project/pdm#1505.

We have to use what we have now.

@lqhuang you can do something like this:

ls packages | xargs -I % sh -c "pdm build -p packages/%"

or taking one step further, create a pdm.sh:

ls packages | xargs -I % sh -c "pdm ${@} -p packages/%"

[lqhuang]

@sinogermany Oh, thanks! That's a good idea and could be wrapped as an alias or shell function 😂
