I'm running geany 1.30.1 on macOS sierra (10.12.3). Although the line wrapping feature is enabled in the preferences, lines are not wrapped. Geany 1.30 on Fedora 25 wraps the lines just fine.
Line wrapping has a per-document setting (*Document -> Line Wrapping*), and the global option only select the value for new files. Is the setting properly enabled for the incriminated files? If not, is it applied for new files?
Ah, okay, I see. The per-document setting was disabled, enabling it gives now properly wrapped documents. New files, however, do not pick the global setting, i.e, their lines are initially not wrapped.
I suggest to add a short note to the global options tooltip that there exist the per-document setting, like the warning that the indentation settings are overwritten by the project settings.
