lino.modlib.memo.parser¶

See introduction in memo : The memo parser.

TODO:

the auto-completer might insert the full text into the editor after the pattern. The user can then decide whether to leave it or not.
The memo commands might also be defined as suggesters with a trigger of type “[ticket “. Note that in that case we need to add a new attribute “suffix”, which would be empty for # and @ but “]” for memo commands.
