I've tried to implement Compass compiling during setuptools' build
, but the following code runs compilation during explicit build
command and doesn't runs during install
.
#!/usr/bin/env python
import os
import setuptools
from distutils.command.build import build
SETUP_DIR = os.path.dirname(os.path.abspath(__file__))
class BuildCSS(setuptools.Command):
description = 'build CSS from SCSS'
user_options = []
def initialize_options(self):
pass
def run(self):
os.chdir(os.path.join(SETUP_DIR, 'django_project_dir', 'compass_project_dir'))
import platform
if 'Windows' == platform.system():
command = 'compass.bat compile'
else:
command = 'compass compile'
import subprocess
try:
subprocess.check_call(command.split())
except (subprocess.CalledProcessError, OSError):
print 'ERROR: problems with compiling Sass. Is Compass installed?'
raise SystemExit
os.chdir(SETUP_DIR)
def finalize_options(self):
pass
class Build(build):
sub_commands = build.sub_commands + [('build_css', None)]
setuptools.setup(
# Custom attrs here.
cmdclass={
'build': Build,
'build_css': BuildCSS,
},
)
Any custom instructions at Build.run
(e.g. some printing) doesn't apply during install
too, but dist
instance contains in commands
attribute only my build
command implementation instances. Incredible! But I think the trouble is in complex relations between setuptools
and distutils
. Does anybody knows how to make custom building run during install
on Python 2.7?
Update: Found that install
definitely doesn't calls build
command, but it calls bdist_egg
which runs build_ext
. Seems like I should implement "Compass" build extension.

Unfortunatelly, I haven't found the answer. Seems like the ability to run post-install scripts correctly there's only at Distutils 2. Now you can use this work-around:
Update: Because of setuptools' stack checks, we should override install.do_egg_install
, not run
method:
from setuptools.command.install import install
class Install(install):
def do_egg_install(self):
self.run_command('build_css')
install.do_egg_install(self)
Update2: easy_install
runs exactly bdist_egg
command which is used by install
too, so the most correct way (espetially if you want to make easy_install
work) is to override bdist_egg
command. Whole code:
#!/usr/bin/env python
import setuptools
from distutils.command.build import build as _build
from setuptools.command.bdist_egg import bdist_egg as _bdist_egg
class bdist_egg(_bdist_egg):
def run(self):
self.run_command('build_css')
_bdist_egg.run(self)
class build_css(setuptools.Command):
description = 'build CSS from SCSS'
user_options = []
def initialize_options(self):
pass
def finalize_options(self):
pass
def run(self):
pass # Here goes CSS compilation.
class build(_build):
sub_commands = _build.sub_commands + [('build_css', None)]
setuptools.setup(
# Here your setup args.
cmdclass={
'bdist_egg': bdist_egg,
'build': build,
'build_css': build_css,
},
)
You may see how I've used this here.
