requirements.txt + pip

1 - look for the following requirements files in the project:

  • setup.py,
  • all files matching req_.txt or req_.pip,
  • all files matching requirements/.txt or requirements/.pip,
  • buildout.cfg and versions.cfg,
  • tox.ini.

2 - Detect inconsistency of dependencies. Same library but multiple versions defined on requirements ( including dependencies that are not explicitly used in the project, but are installed by the libraries that are used in the project )

Example:
the library A depends on FOO >= 1.0 library and B library

B library depends on FOO <= 0.8

In the end you will have a problem because B installed an older version of the FOO library, but A depends on a recent version of FOO library

ps: Sorry my english, I'm still learning

@luzfcb Thanks for your suggestion!
Python community does not have a library for this type(like bundler, carton, david, composer) yet? Create this from scratch is a bit hard I think 😲

The only one I know of is the pip [1].

about 1: https://requires.io already does this well. See full example here[2]

about 2: pip can detect when there is explicit duplication of a library on requirements files (at least when using -r option)
example.: pip install -r foo_file.any_extension

but so far, not figure out if it detects, or force it to detect the inconsistencies of dependencies that are not explicit on defined on requirements files.

requires.io not do that at the moment, but it would be extremely useful

ps.: do not know deeply the mentioned tools. in fact the only one who got to use was the composer for php language

@sanemat

beyond the pip, and perhaps srclib[1] and srclib-python [2]

https://sourcegraph.com/ is a service ( I still do not understand exactly what it does) made upon srclib

@waghanza Sorry, There is no progress.
I recommend you to do like this https://moneyforward.com/engineers_blog/2017/08/31/bye-tachikoma-gem/#post-7045-md-12
I want to know your own solution! Thanks!

@sanemat I always used requirements.txt (or requirements-dev.txt) conventions on python module.

I haven't yet see the code, but I'll probably parse the pypi api
