Blender addons use a version identifier that consists of three numbers, for example:
bl_info = {
"name": "Awesome object generator",
"author": "Me",
"version": (1, 0, 20150425140302),
"blender": (2, 74, 0),
"location": "View3D > Add > Mesh",
"description": "Adds an awesome object at the 3d cursor",
"warning": "",
"wiki_url": "",
"tracker_url": "",
"category": "Add Mesh"}
I do virtually all addon development with the help of
Notepad++ and I really wanted to have a way to automatically update this version information when I change something. Cvs (and svn) have functionality to update specific strings but I wanted to use this addon version information because having two different tags doesn't sound logical to me. Fortunately with the help of the
Python Script plugin for Notepad++ it is quite simple to create a save event listener that does exactly what I want:
from datetime import datetime
# Just in case, we'll clear all the existing callbacks for FILEBEFORESAVE
notepad.clearCallbacks([NOTIFICATION.FILEBEFORESAVE])
def ts(m):
dt=datetime.now()
ds=dt.strftime("%Y%m%d%H%M%S")
return m.group(1)+ds+m.group(3)
# Define the function to call just before the file is saved
def addSaveStamp(args):
currentBufferID = notepad.getCurrentBufferID()
notepad.activateBufferID(args["bufferID"])
editor.rereplace(r"(version.*?\(\s*?\d+\s*,\s*\d+\s*,\s*)(\d+)(\s*\))", ts)
notepad.activateBufferID(currentBufferID)
# ... and register the callback
notepad.callback(addSaveStamp, [NOTIFICATION.FILEBEFORESAVE])
If you place that code in the
startup.py file (typically in your roaming profile, for example:
C:\Users\Michel\AppData\Roaming\Notepad++\plugins\config\PythonScript\scripts\startup.py ) and make sure the Python Script plugin is activated on startup (by selecting
Plugins -> Python script -> Configuration -> Initialization = ATSTARTUP and restarting Notepad++) then any subsequent save will look for a version identifier and will replace the third number with a timestamp.
