Branch: refs/heads/master Author: Sylvan Mostert smostert.dev@gmail.com Committer: Sylvan Mostert smostert.dev@gmail.com Date: Fri, 09 Sep 2016 05:45:32 UTC Commit: f0fa9e8c150b36ae6b1be241299ad70266cf5367 https://github.com/geany/geany-plugins/commit/f0fa9e8c150b36ae6b1be241299ad7...
Log Message: ----------- lineoperations: added selection support
If there is a selection, the Operation will be applied to the lines in the selection, and if there is no selection, the Operation will be applied to the whole file.
Adjusted `rmemtyln` and `rmwhspln` to accept first line and end line for selection.
