2016-02-07hooks.c: Fix window preparation in interactive modeLukas Fleischer
In commit 2857bac (Fix segfault when running hooks in non-interactive mode, 2016-01-16), we added checks to fix a segmentation fault in non-interactive mode. However, at the same time, that commit broke window preparation in interactive mode. When wins_prepare_external() is called, the UI mode is changed to command line, such that we cannot determine whether we need to call wins_unprepare_external() when returning from the hook. As a workaround, we now store the mode in a temporary variable. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

2016-01-07Add pre-save and post-save hooksLukas Fleischer
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.
