Hi,
I update my MakeHuman svn source and the Blender svn source on a daily
basis. Currently the Blender folks did a change in the registration
code for Blender scripts. The MakeHuman folks provide a script, which
is needed to load the putput of MakeHuman into Blender. This script
isn't "new registration ready".
I have to do the following the changes to the Makehuman script (a
handfull):
change this: =======================================
def registration()
<script specific stuff
def unregistration()
<script specific stuff
into this: =========================================
def registration()
bpy.utils.register_module(__name__)
<script specific stuff
def unregistration()
bpy.utils.unregister_module(__name__)
<script specific stuff
until the MakeHuman folks have time to integrate my patch into their
code.
Since I do update often I would have to edit all these files by hand
every time.
It would be much more time saveing, if a sed-oneliner from the
commandline, saved into the shell history, could do this for me....
I googled a little in beforehand and found the "a" command, but I
didn't managed to get it working for me...so...
Best regards,
mcc
