User:Jiangxin/Patch save extra attributes outof mmfile
From FreeMind
Jump to navigationJump to search
Why this patch?
All my .mm files are version controled using CVS/SVN. What FreeMind has scratched my personal itch:
- Some attributes of FreeMind's .mm file are not suitable for version control.
- e.g., 'FOLDED' attribute saved in .mm file, makes documents changed frequently and unnecessarily.
Overview
This patch is for saving extra node data into .mmx file. Attributes saved in .mmx file will be loaded when .mm file is open.
As how to take .mmx file as a reference when loading .mm file, is in another patch:
WhiteAttlist, BlackAttlist, and EmAttlist:
- attributes listed in WhiteAttlist are the only attributes should be saved to files.
- attributes listed in BlackAttlist are the attributes shouldn't be saved to files.
- attributes listed in EmAttlist will be list in a single line. (a kind of EMphasis)
Patch file
this patch is for freemind 0.9
