Lentic can serve as a reasoanble replacements for indirect-buffers now that it runs efficiently. For 0.9 there will be a “make-lentic-buffer” function that is a direct replacement for “make-indirect-buffer”.
Going to try updating polymode, minimap or sublimity-mode to use these as my test cases.
Currently, when sync-point is false (as is the case for a “view”), point can jump around the buffer. This happens when lentic falls back to a full buffer replace – as all of the contents of the buffer is deleted point has to move.
The fix to this is to put a marker in this-buffer for the location of that-buffer before the change, and then move the location for point to in that-buffer to the same location after the change; as a fall back (when for instance the location of point in that buffer is deleted, we can move to the start of the region deleted.
Currently, the orgel->org is not very good, so I want to improve this. In particular, I want to support :tags: because lots of people want them. The block detection improvement needs changing to support many different source blocks types in the same buffer. Finally, the export for orgel->org is not ideal. At least it needs to hide “Header” (without having to use :noexport: everytime).
I think that the headerline could be nice to show when lentic mode is invalid in some way.
