Unfortunately this breaks compability with the minimum GTK/GLib requirements. G-P uses the same minimum GTK/GLib versions as Geany and for GLib this is currently 2.28. However, g_hash_table_contains() is first available in GLib 2.32.
You could either tell autotools to build the plugin only if GLib 2.32 is available (i.e. depend on it) or maybe write some simple compatibily function to implement g_hash_table_contains() when GLib < 2.32 is used. I guess this can be easily done using g_hash_table_foreach() or maybe g_hash_table_lookup(). --- Reply to this email directly or view it on GitHub: https://github.com/geany/geany-plugins/commit/e71d268faceb8bbbb71bd09e176173e02e373f56#commitcomment-15491671
