Hello,
I am working on the pyfai package.
This pacakge contain one module with extensions (the important point)
The new upstream version 0.14.0 provide a build_man target via the setup.py
So in ordert to generate the doc I need to do
python setup.py build_man
Now if I look at this target, I can find this code
-----
class BuildMan(Command):
"""Command to build man pages"""
user_options = []
def initialize_options(self):
pass
def finalize_options(self):
pass
def entry_points_iterator(self):
"""Iterate other entry points available on the project."""
entry_points = self.distribution.entry_points
console_scripts = entry_points.get('console_scripts', [])
gui_scripts = entry_points.get('gui_scripts', [])
scripts = []
scripts.extend(console_scripts)
scripts.extend(gui_scripts)
for script in scripts:
elements = script.split("=")
target_name = elements[0].strip()
elements = elements[1].split(":")
module_name = elements[0].strip()
function_name = elements[1].strip()
yield target_name, module_name, function_name
def run(self):
build = self.get_finalized_command('build')
path = sys.path
path.insert(0, os.path.abspath(build.build_lib))
env = dict((str(k), str(v)) for k, v in os.environ.items())
env["PYTHONPATH"] = os.pathsep.join(path)
import subprocess
status = subprocess.call(["mkdir", "-p", "build/man"])
if status != 0:
raise RuntimeError("Fail to create build/man directory")
import tempfile
import stat
script_name = None
entry_points = self.entry_points_iterator()
for target_name, module_name, function_name in entry_points:
logger.info("Build man for entry-point target '%s'" % target_name)
# help2man expect a single executable file to extract the help
# we create it, execute it, and delete it at the end
py3 = sys.version_info >= (3, 0)
try:
# create a launcher using the right python interpreter
script_fid, script_name = tempfile.mkstemp(prefix="%s_" % target_name, text=True)
script = os.fdopen(script_fid, 'wt')
script.write("#!%s\n" % sys.executable)
script.write("import %s as app\n" % module_name)
script.write("app.%s()\n" % function_name)
script.close()
# make it executable
mode = os.stat(script_name).st_mode
os.chmod(script_name, mode + stat.S_IEXEC)
# execute help2man
man_file = "build/man/%s.1" % target_name
command_line = ["help2man", script_name, "-o", man_file]
if not py3:
# Before Python 3.4, ArgParser --version was using
# stderr to print the version
command_line.append("--no-discard-stderr")
p = subprocess.Popen(command_line, env=env)
status = p.wait()
if status != 0:
raise RuntimeError("Fail to generate '%s' man documentation" % target_name)
finally:
# clean up the script
if script_name is not None:
os.remove(script_name)

As you can see this create a launch script for each entry point found in the setup.py and run help2man on it.
For now I would like to use this setup.py without modification.
So what should I do to run
python setup.py build_man with the options provided by pybuild during the normal build in order to let the generated script find the pyFAI modules and its extensions ?
