emacs-font-lock-studio 0.0.10

Interactive debugger for Font Lock keywords

Font Lock Studio is an interactive debugger for Emacs syntax highlighting rules, also called Font Lock keywords. It can single-step Font Lock keywords -- matchers, highlights, and anchored rules, to see what happens when a buffer is fontified. Breakpoints can be set on or inside rules. When inside a rule, matches are visualized using a palette of background colors. The explainer can describe a rule in plain-text English. Finally, tight integration with Edebug allows stepping into Lisp expressions that are part of the Font Lock keywords.
