Hi. I am trying to make me a log reading major mode. I want to be able to change face of text matching certain regexps. To achieve this, I set font-lock-defaults and this works.
My problem is that I would like to be able to change what text that is to be specially faced as I go along,
i.e. identify interesting texts and add - or subtract - them from the regexps without having to revisit the file.
Let say I usually want to highlight write, read and weblog. I use this: (defvar log-font-lock-keywords
'(("\\(\\write\\)" . font-lock-function-name-face)
("\\(\\weblog\\)" . font-lock-doc-face)
("\\(\\read\\)" . font-lock-keyword-face)
"Keyword highlighting specification for `log-mode'.")
As I read 061205.log, I decide not to highlight "weblog" any more. How do I disable it? Later on, I want to highlight "user" instead, now with font-lock-comment-face. How do I do that? I do not want to close the file to reopen it again.
Best Regards Matzi
This is my attempt so far. It is a surprisingly small amount of code, but then again, it does not do what I want. =)
