Hi, I'm writing a simple plugin for geany (which I will call LiveDiff) which allows for having indicators inside the editor for changed/added/modified lines, which is updated as you type. The base for comparing the buffer can be either the version of the file on disk or (which I will soon attempt to add) the latest version from the git repository, if the file is versioned so. This resembles what netbeans does (one something I really liked). So far it works OK but there are some quirks. I'm doing this out of spare time so dont expect a pretty serious commitement to it. I will however make it available on github.
I wanted to ask regarding the ScitillaObject handling. Currently my plugin needs to define RGBA markers (which are used to indicate the diff results per-line). What it is not really clear to me is that there appears to be one ScintillaObject associated with each GeanyDocument. However, some messages sent to the ScintillaObject (like changing the margin or defining markers) appear to be global across all instances (unless I'm mistaken). Is this so? What would be the proper handling? Is it ok to repeat the definition of the markers for each editor?
Moreover, I'm not sure how to handle correctly the size of the RGBA markers since it depends on the font size of the editor. I tried to set the marker scale using the text_height to image height ratio, but the marker still appears to be a bit taller than the line and this creates some visual artifacts.
Best, Matias
