Hello there; has anyone here succesfully used the

pdm.backend

build system with a dynamic build version from scm through

pants package ::

? On our current project, we've been trying to use git tags to automatically setup build versions, i.e. with the following tag

subproject/X.Y.Z

, PDM can automatically fetch the tag version using

pdm build

to produce the corresponding distribution

dist/subproject-X.Y.Z-py3-none-any.whl

. However, through

pants package ::

, the backend doesn't seem to have access to those git tags. Has anyone else experienced this ? Is there a way to include those tags into the packaging process ?

Pants runs every process in a hermetic sandbox, so it does not have access to git state unless you take steps to make that happen

Hmmm, PDM allows passing the version directly as an environment variable using

PDM_BUILD_SCM_VERSION=X.Y.Z

; I'll check

[subprocess-environment]

next. Thanks for the idea !

Well but where would you get that VERSION from? I assume you want PDM to compute it?

Ideally, yes, the PDM backend should be able to parse the version from tags using the provided

tag_regex

( see repro ) Havent had the time to dwelve into PDM's implementation yet however so it may or may not depend on the

git tag

command; it could probably just be a simple glob search into

.git/refs/tags

folder However this backend does not requires to run PDM in the project's root folder; it does resolve the current git repository from the closest parent folder automatically.

Unfortunately the sandbox dirs are not under the repo
