propfont-mixed

Enable use of variable-width fonts for displaying symbols, in a way that does not conflict with fixed-width-space-based indentation.

Screenshot

Here is an example: it is a C-file in emacs source, which uses mixed space/tab indentation. Short words, special symbols, and those words that are judged to be anchors for other lines' indentation are displayed with the default font, other words are displayed with the variable-width font. Note that the indentation looks correct, unlike what it would be if I enabled the variable-pitch-mode instead.

Notes

• Customize propfont-mixed-inhibit-regexes to forbid some symbols from being shown with proportional fonts. See also propfont-mixed-inhibit-function, and propfont-mixed-inhibit-faces.

• It is probably necessary to adjust the face variable-pitch, so that the proportional font looks good and is the correct size.
