4.1.6 Patcher Instances

The concept of subproject brings up the question of having Patcher working on different patches at the same time. It is possible under some conditions:

• You can have as many simultaneous Patcher instances as you want on projects that don't overlap.
• You can have as many simultaneous Patcher instances as you want on the same project, as long as there is no overlapping between each subproject. This means that you can't have source files, or even ChangeLog files in common.
• It is also possible, to some extent, to work simultaneously on overlapping instances of Patcher, although this is mostly uncharted territory. More precisely, Patcher keeps track of which project(s) refer to specific source or ChangeLog files, and knows how to associate a particular ChangeLog entry with a particular project. However, Patcher does not support interactive selection of patches (à la Darcs or Git) yet, and if you commit one of two overlapping projects, you will most likely need to rediff the other one.
