From 767214e4f157ae4a74be0b557bd49e24d972970b Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Thu, 7 Jan 2016 18:23:09 +0100 Subject: Add pre-save and post-save hooks This adds support for hooks which are executed before/after saving calcurse data. Hooks can be placed under hooks/pre-save and hooks/post-save in the data directory and need to be executable. Potential use cases include: * Automatically commit any changes to the data files using a VCS. * Automatically sync with some sever component on data file changes.
