How to set multiple indentation widths in Geany?

I use Geany mainly for Python, so I've set Indent Type to Spaces and Indent Width to 4. But when working with HTML, I'd like to use 2 spaces.

Is there any way to tell Geany to automatically switch to 2 spaces when working with HTML documents instead of being changing this manually all the time?

Solution

You can set indention by filetype or by project. To configure it via filetype copy the filetypes.filetypename from data folder of your Geany installation into your ~/.config/geany/filedefs folder and change

[indentation]
width=4
type=1

to what you like. Please check manual for details.
