Geany is a text editor using the GTK2 toolkit with basic features of an integrated development environment. It was developed to provide a small and fast IDE, which has only a few dependencies from other packages. It supports many filetypes and has some nice features. If you need the GTK Symbol completion tags (removed in Geany 0.16), get them (and other tag-files) from: http://download.geany.org/contrib/tags/ the easiest way to download them all is: lft -c "open http://download.geany.org/contrib/tags; mirror ." The first option is to put them in $CWD at the time you build the package. Then tell the SlackBuild to include support for tags: TAGS=yes ./geany.SlackBuild The second option is to download them and and place them in the ~/.config/geany/tags/ directory. You will then need to restart Geany for this to take effect.
