I mean that if I have 5 different summary line formats for 5 different "type of" Groups: nntp, private mail, mailing list, server logs .... For all Gnus uses gnus-summaryline-format and that's what it byte compiles too. But if I shift in the custom format to the gnus-summary-line-format, I have to byte compile, and when I shift in format2, I have to byte compile it again... So I wanted to pre-byte-compile these 5 different formats, so that I could do: (setq gnus-summary-line-format fmt1) (setq ...byte-compiled-definition fm1-byte-compiled) Instead of (setq gnus-summary-line-format fmt1) (gnus-update-format-specifications 'force) which would mean constant byte compiling whenever I would change Groups.... jari ^ permalink raw reply [flat|nested] 10+ messages in thread

It wastes > both disk and memory when a simpler solution already exists. Using that argument, you could also claim that saving bytecompiled specs to `.newsrc.eld' at all is "utterly and completely unnecessary", too. The whole point of caching the compiled specs is not having to invoke the byte-compiler each time you have to deal with them. Why this cache would suddenly become unnecessary when you deal with more than one specification is beyond me. > Hrvoje> I've never said it was bad to invoke the byte-compiler, but > Hrvoje> I did imply that the code should be designed so that its > Hrvoje> invocation is not mandatory. > > The invocation is *NOT* mandatory now.

Here's the recommended way to set `gnus-summary-line-format', taken from gnus-gl.el. Adapt it to your requirements: ;; Change how summary lines look (make-local-variable 'gnus-summary-line-format) (make-local-variable 'gnus-summary-line-format-spec) (setq gnus-summary-line-format gnus-summary-grouplens-line-format) (setq gnus-summary-line-format-spec nil) (gnus-update-format-specifications nil 'summary) (gnus-update-summary-mark-positions) replacing `gnus-summary-grouplens-line-format' with your prefered format. - Hari -- Raja R Harinath ------------------------------ harinath@cs.umn.edu "When all else fails, read the instructions." -- Cahn's Axiom "Our policy is, when in doubt, do the right thing." -- Roy L Ash ^ permalink raw reply [flat|nested] 10+ messages in thread
