I always wanted to write an OD plug-in for myself. Finally referenced many codes. After copying the code of many people I have written an OD2.01 character search plugin.
I have never touched the OD plug-in before, and it took about two and a half days to write this.
I feel that the OD2.01 plug-in is simpler to write than 1.x because most of the code I refer to is 1.x, which feels a bit complicated. After trying to figure out the whole structure by myself, it feels quite simple.
The main difficulty is that there is no API manual. The API on the official website is not complete. Basically, it takes more time to test the API.
Can search ASCII and UNICODE. Includes "Find" and "FindNext" options.
