How can I set widths of individual tab characters with a plugin? Follow Answered Matěj Bagar Created January 03, 2021 17:47 I'm trying to implement elastic tabstops for IntelliJ Idea. That requires calculating how far each tab should reach according to surrounding lines and stretching it that far. I can't find any mention of setting tab width in the SDK DevGuide. Automatically indenting with spaces is not viable because it doesn't work well with proportional fonts.
