Yep, it's by design to make installation as fast as copying some files from
a zip file.

Another option is to look at PEP 517-compatible tools like Enscons which
will give you more control over the wheel compilation process without
having to try to hack your way into Setuptools.

This can't be done.  `pip install` installs from wheel (.whl) files, and that 
installation process currently (and, I believe, by design) has no provision for 
running arbitrary code.  You have two options:

1. Extend the `setup.py bdist_wheel` command to compile & bundle the 
translation files as part of building the wheel.  I personally don't know how 
to do this, but I believe the process is somewhat similar to extending the 
`setup.py install` command.  Note that if the compiled translation files are 
architecture-dependent, you'll also need to add the appropriate tags to the 
wheel.

2. Give your library a `boot_em_all_compile_translations` command for compiling 
the translation files, which the user must then run manually after installation.

[Distutils] Execute command before pip install

[Jorge Maldonado Ventura]

I need to execute a command automatically when running `pip install` to 
solve https://notabug.org/jorgesumle/boot-em-all/issues/1


I need to do that to compile the translation files. I found that 
overriding the `setuptools.command.install` makes it work with `python3 
setup.py install`, but I want it to work with pip as well. Any advice or 
think I overlooked? Is there a clean or recommended way to do this?


The whole code is free software, so you can check my `setup.py` file. 
The repository can be cloned executing `git clone 
https://notabug.org/jorgesumle/boot-em-all`.
