I've gotten the bundled python interpreter to load extensions not bundled in
library.zip (absolute path on rhs in %HOMEPATH%\Mercurial.ini)...
Native installed python (python:extmodule.function) hooks, on the other hand
don't work as well. You can still specify an absolute path to a python file
(without python:), but since it executes in a subshell, you'll only be able
to access the variables passed through the os.environ dict.
If you have the time a patience, you can get native hooks working another
way:
1) All extensions in the binary distribution's Mercurial.ini MUST load
correctly
2) Write an extension that, from uisetup, calls ui.setconfig with the
appropriate section and name. BUT- Instead of passing a string for value,
pass a callable (defined or imported elsewhere by your extension)
This is in some c:\src\share\hgext\myhooks.py:
>>>
def dosomething(*args, **kwargs):
print "---- BEGIN my hook ----"
for k, v in kwargs.iteritems():
print "%s: %s"%(k, str(v))
print "---- END my hook ----"
def uisetup(ui):
ui.setconfig('hooks', 'pre-commit.peekvalues', dosomething)
<<<
Adding the following section to the repository or user local
hgrc/mercurial.ini:
>>>
[extensions]
myhooks=c:\src\share\hgext\myhooks.py
<<<
Will load said hook for a pre-commit command hook:
>>>
C:\foo\test4>hg -v --traceback commit
---- BEGIN my hook ----
repo: <hgext.mq.mqrepo object at 0x02A39470>
args: -v --traceback commit
ui: <mercurial.ui.ui object at 0x024B6570>
hooktype: pre-commit
---- END my hook ----
nothing changed
