Python module import analysis tool

Project description


FindImports extracts Python module dependencies by parsing source files. It can report names that are imported but not used, and it can generate module import graphs in ASCII or graphviz formats.

A distinguishing feature of findimports used to be that it could parse doctest code inside docstrings.

Note that not all cases are handled correctly, especially if you use ‘import’.

If you need to find unused imports in your codebase, I recommend Pyflakes instead – it’s better maintained and more reliable. For import graphs consider pydeps.

  • Add --package-externals/-pE to simplify the module graph.

  • Add --rmprefix PREFIX/-R PREFIX to remove a package prefix from displayed names.

  • Add --depth N/-D N to ignore import statements nested too deep in the syntax tree (e.g. in functions or if statements).

2.3.0 (2022-10-27)

  • Rewrote command-line parsing to use argparse. Options that select an action (--imports/--dot/--names/--unused) now conflict instead of all but the last one being ignored. See pull request #20.

  • Add --ignore-stdlib flag to ignore modules from the Python standard library.

2.1.0 (2021-05-16)

  • Add --ignore flag to ignore files and directories, it can be used multiple times. See pull request #14.

2.0.0 (2021-05-09)

  • Add support for Python 3.9.

  • Drop support for Python 3.5 and 2.7.

  • Fix a bug where the encoding of Python files was not determined in the same way as by Python itself. See issue 15. This requires the use of which is not in Python 2.7.

1.5.2 (2019-10-31)

  • Add support for Python 3.8.

  • Fix a bug where a package/module with a name that is a prefix of another package/module might accidentally be used instead of the other one (e.g. py instead of pylab). See issue 10.

1.5.1 (2019-04-23)

  • Drop support for Python 3.4.

1.5.0 (2019-03-18)

  • Drop support for Python 2.6 and 3.3.

  • Suppress duplicate import warnings if the line in question has a comment.

1.4.1 (2016-09-28)

  • Replace getopt with optparse. This changes the --help message as a side effect (#4).

1.4.0 (2015-06-04)

  • Python 3 support (3.3 and newer).

  • Use ast instead of compiler (#1).

1.3.2 (2015-04-13)

  • Fix “cannot find datetime” on Ubuntu 14.04 LTS (#3).

  • 100% test coverage.

1.3.1 (2014-04-16)

  • Added support for relative imports (e.g. from .. import foo).

1.3.0 (2013-04-10)

  • Moved to Github.

  • Drop Python 2.4 and 2.5 support.

  • Handle unicode docstrings with doctests.

1.2.11 (2011-03-30)

  • Fix ‘could not find cPickle’ errors on Python 2.6 and newer.

1.2.10 (2010-02-05)
