Any way to automatically sync deps when running pdm run script?

[Wesztman]

I would like to remove my tox dependency from my project, but it's very simple for new user to just check out and run "tox" only, and the deps are synced automatically.

The new workflow would be to both run "pdm sync" and then "pdm run X" where X is a script with all tests and checks, same as tox runs.

Since tox just use the scripts from pdm/pyproject atm it seems like tox is not really necessary.

Is there any way to get "pdm run" to sync deps before executing? I.e make the script dependant on a group of deps so to say?

This would mean an equally simple workflow where the user checks out the repo and just run "pdm run X" which then creates venv, install deps and run command.

It seems that the run command creates a .venv before executing, but there are no deps installed in it.

This would also mean that I would not have multiple venv:s with the same deps since tox creates one and pdm creates one.

Maybe that got confusing... Feel free to ask if I should clarify something :p

Cheers
Carl

[tool.pdm.scripts]
pre_run = "{pdm} sync"

That works, but it run 3 times times for a composite with 3 scripts, any way to get it to run only one time?

EDIT: Changed to "pre_all" that works a little better 😊

But there is still alot of clutter, any way to not show the info prints? Tried to find a log level setting with no success 🤔

While I'm at it, a question on the INFO: The saved Python interpreter doesn't match the project's requirement. Trying to find another one. . I'm using Python 3.12.2 and my pyproject.toml sais requires-python = ">=3.9". Am I missing something if I get this print? 🤔 Because the python used should satisfy the requirements.

It runs on every invocation of pdm run, actually you don't need to call pdm run in tasks:

[tool.pdm.scripts]
pre_run = "{pdm} sync"
ruff-lint = "ruff check . --fix"
mypycheck = "mypy ."
lint = { composite = ["ruff-lint", "mypycheck"] }

Your solution pre_all only runs when running task all

You may have saved an incorrect python path in .pdm-python, check and remove it if necessary.

Thanks for all the answers :) last question, is there any configuration to not output the info logging prints?

The problem was that in my devcontainer I had set

But ${workspaceFolder} apparently does not expand properly in containerEnv for some reason.

Removing the PDM_PYTHON env var solved the issue (I don't need it anymore anyway).

Now it works like a charm 😄 final code

Works like a charm

I might do a PR sometime to add a "title" option to scripts, something like

[tool.pdm.scripts]
typecheck.cmd = "mypy ."
typecheck.title = "Running type checks"

Do you think it would be a feature that would get merged? 😊
