Organization of large corporate project - mono/multi repo

[pbaetens]

Hi,
I'm looking for some ideas to organize our corporate python project.
Currently, we host about 30 python packages in multiple gitlab repositories. 1 package per repo. Each package has its own test scripts and version number.
Most of those packages have some dependencies to each other, with 1 package serving as 'main' repo.

Using git-submodules we checkout all packages to C:\companyfolder\

• C:\companyfolder\mainrepo
• C:\companyfolder\packageA
• C:\companyfolder\packageB

We want to be able to work on all packages at once.

main_repo/pyproject.toml looks like:
[tool.pdm.dev-dependencies]
local = [
"-e file:///C:/companyfolder/repoA",
"-e file:///C:/companyfolder/repoB",
.....
"-e file:///C:/companyfolder/repoZ",

to me, it feels rather complex, there must be a better way..
