Geany editor themes

File paths

  • System-wide config files are in /usr/share/geany
  • USer-specific config files are in $HOME/.config/geany
  • Files placed in the user-specific folder will overwrite the code in files placed in the syste-specific folder
  • Don’t make changes directly in the system files, those will be overwritten when Geany is updated

File names and extensions

  • The general colorscheme for the editor is a .conf file in the colorschemes directory. For example: monokai.conf
  • The programming language specific file is a filetypes.ext file where .ext is your programming language extension. For example, filetypes.markdown for Markdown, filetypes.js for JavaScript and filetypes.sh for Bash files. These files placed in /$HOME/.config/geany/filedefs/ will overwrite the code in default files placed in /usr/share/geany/.

Making changes

  • Colors can be HEX values, prepended with either a # or a 0x. For example: #ff0000 or #f00 or 0xFF0000 are all valid values for Red.
  • You can save all your colors as named variables under the [named_colors] section

 3color_orange=#FF6400
 4color_light=#ECF0F1

15# bold and italic are true/false flags, i.e. boolean values (false is default)

17default=color_light;color_navy
18strong=color_mustard;color_navy;true;false
  • The styling takes 4 values for every key. The values are:
    • Foreground color (takes a named color or a HEX value)
    • Background color (takes a named color or a HEX value)
    • Bold (takes a true/false value)
    • Italic (takes a true/false value)

Below are all valid ways of writing the values
