Makes entry_points specified in load more quickly

pip install fastentrypoints==0.12


Fast entry_points

Using entry_points in your makes scripts that start really slowly because it imports pkg_resources, which is a horrible thing to do if you want your trivial script to execute more or less instantly. check it out:

importing fastentrypoints in your file produces scripts that look like this:

# -*- coding: utf-8 -*-
import re
import sys

from package.module import entry_function

if __name__ == '__main__':
  sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])

This is ripped directly from the way wheels do it and is faster than whatever the heck the normal console scripts do.


This bug in setuptools only affects packages built with the normal method. Building wheels avoids the problem and has many other benefits as well. fastentrypoints simply ensures that your user scripts will not automatically import pkg_resources, no matter how they are built.


To use fastentrypoints, simply copy into your project folder in the same directory as, and import fastentrypoints in your file. This monkey-patches setuptools.command.easy_install.ScriptWriter.get_args() in the background, which in turn produces simple entry scripts (like the one above) when you install the package.

If you install fastentrypoints as a module, you have the fastep executable, which will copy into the working directory (or into a list of directories you give it as arguments) and append include to the file, and add an import statement to It is available from PyPI.

You can't really make it a proper dependency because setuptools has to import it to work, so chicken-egg. right? Luckily, the script is trivial and will not hurt you project much to copy this 60-line file into the folder. Be sure to add it to MANIFEST.ini if you want to distributie it on PyPI.

Alternatively, if you don't want to vendor the code, it is possible to install it from pypi with easy_install in the setup script:

    import fastentrypoints
except ImportError:
    from setuptools.command import easy_install
    import pkg_resources
    import fastentrypoint

Let me know if there are places where this doesn't work well. I've mostly tested it with console_scripts so far, since I don't write the other thing.
