2014-08-31First part of a vi like frontendMarc André Tanner5-108/+363
Still very incomplete

2014-08-23text: invalidate line <-> pos mapping upon undo/redoMarc André Tanner1-0/+2
2014-08-23text: redesing mark implementationMarc André Tanner1-20/+16
Previously a mark was a byte offset from the start of the file which required updates whenever a text modification happened before it. Now it is simply a pointer into the underlying (mostly) append only buffer which remains valid throughout the whole life cycle.

2014-07-22Remove unnecessary special case for inserting into an empty documentMarc André Tanner1-21/+7
2014-07-22Fix bugs in caching layerMarc André Tanner1-8/+27
Thw lenght of the whole text (ed->size) also has to be updated. Also do not allocate changes if the operations are performed in the cache.
2014-07-22Add some more commentsMarc André Tanner1-2/+26
2014-07-21Introduce cache layerMarc André Tanner1-27/+108
If multiple consecutive modifications happen to lie within the same piece perform the operations "in place". In particular no new pieces will be allocated if the changes occur at the end of the most recently modified piece. In this case the piece is simply extended. However changes in the middle of a piece involve memove(3) calls which might hurt performance. Since no new pieces are created the changes can't be undone on an individual basis. The frontend should therefore call 'editor_snapshot' at appropriate times inorder to invalidate the cache.
