A user working on a project that is doing portions of Old Testament books (roughly 40% of the OT) and requested how to set up the project plan to only include those chapters. Paratext does not yet have a way to do this in the book selection tab for the project properties, but I think it is possible to do a workaround within the project plan.
I created a test project using the SIL Compact Plan. I added a task to the beginning of stage 1 called “Selection”, and i made sure the Exegesis task (formerly the first task in the stage) was set to begin when previous task was complete. Then in Assignments and Progress I marked as completed for the Selection task the chapters to be included. I found that subsequent tasks could be simply marked as all complete by clicking the box for All chapters, and that only marked the desired chapters as complete. I could use the + and - buttons to start marking chapters in numerical order as complete, and it would skip over the unselected chapters. Or one could bring up the list of chapters to indicate nonsequential progress, and the non-selected chapters would be grayed out, and Paratext wouldn’t accept a check there if someone clicked the wrong box.
One other issue, the book could not advance out of stage 1 because the chapter/verse check would report issues for all the empty chapters. (Either “verses missing” or “empty verses” depending on whether there were verse number markers present) But if I brought up the list of issues and denied all the “verses missing” or “empty verses” reports, then the automatic check reported no errors and I could mark stage 1 as complete and advance to the next stage.
