GtkSourceView 2 API frozen
With yesterday night release of GtkSourceView 1.90.5 (which will likely become 2.0 next week) we consider the API frozen and in the future releases only API additions will happen.
Honestly we hoped to have more early adopters so that we could have more feedback on the API changes, but I can understand how painful it is to track a library that it is a bit of a moving target :)
Anyway, now it’s a good time to start porting your app to GtkSourceView 2 and an even better time to bind it to your favourite language (Python bindings are already available). Why? Because you get a way more accurate syntax highlighting and because you get support for style schemes.
I will not go into the details of the API changes (most of it should be straightforward), my advice is just to be careful with the memory management of the
StyleSchemeManager: unless you want to do advanced stuff like a style scheme editor or use two separate highlighting contexts in the same app, you should probably stick to the singletons provided by GtkSourceView itself.
That said, I should also point out that there are a few feature regressions with respect to GtkSourceView 1 and anyone getting ready to port his app should be aware of that:
- Printing support was dropped: GtkSourceView 1 depended on gnome-print which is now deprecated, this days printing should be done with gtk itself.
- GtkSourceMarkers were dropped: they were pretty much the only API that is not exercised by gedit and we didn’t feel comfortable enough with the API to set it in stone.
We are more than willing to reintroduce these features back in 2.2 (though printing is a bit of a gray area since bits of it really belong to gtk itself), but we need feedback from the apps using the library to get the API right!
