Dired key: It would be nice to have a defcustom value that would specify a dired map key that would call doc-view on a file (with a new doc-view function that doesn't prompt for the file name). This would make it easier to browse pdf files in dired. Good idea. I'll add that. Do you have a good suggestion what key could be used and is free? How about b (for browse) or V (for View)? I think 'b' is available. However, you may find it useful to do what I did in my txutils.el package. I used defadvice around view-file (which is bound to v in dired). Since I was asked to include doc-view.el in Emacs I'm not sure if defadvice would be too good. AFAIK RMS doesn't like it too much. Actually, this is a misunderstanding of RMS' position. It is true he doesn't want defadvice used in packages that are part of emacs, but thats not because he doesn't like the mechanism. His view is that it could make debugging of problems harder because it can obscure what is going on. As a facility to change exisitnig functionality, he has no issue with it. So, yes, your right you shouldn't use it if the package is going to be part of emacs, but incorrect on the reason. However, since it will be part of emacs, there is no reason you couldn't ask for a change - either to how view-file works or to how/what is bound to the 'v' key in dired. For exmaple, you could create a new funciton that is bound to v which does things specific based on the file extension. So, now if I hit v on a pdf, ps, doc, ppt html etc file, it converts the file to either text or html and then displays it in a buffer (in the case of html output and .html files, it just uses browse-url to display the rendered version). At least for PS files that may not be the right thing. Users might want to view it with `ps-mode' instead. One of the nice things about advising view-file is that you still get standard behavior if you just hit enter i.e. if you hit enter on a ps file, it will just open the file in ps-mode. However, ps-mode is I think for hacking at the postscript level rather than for viewing. The nice thing about the txutils package is that all of this is controlled by a customizable variable. If you remove the translation entry for PostScript, then no conversion will occur.

Stefan Monnier [EMAIL PROTECTED] writes: [ Please guys, this is a sources-only newsgroup. ] I posted this reply to the emacs help newsgroup as well. Presumably any further discussion should occur there. Well, why do you think you have to wait? Go on with your work and eventually the *DocView* buffer pops up. (That's much better in the current version now.) The convert process seems very resource hungry as my Powerbook G4 slows to a crawl (and is basically unusable) when I'm converting a large (2MB) PDF file. On small PDF's, it's still usable (but slow). I thought that a batch option would provide an alternative that might not be as intrusive. Think about it hard: since you can do other things in Emacs in the mean time, it's already running in the background. If your G4 becomes basically unusable, the best guess is that the conversion process uses up all disk and memory resources, in which case there's not much you can do: even lowering its CPU-priority will not buy you much responsiveness. I was thinking more in terms of kicking off a process that wasn't tied to the Emacs calling process in any way (at present, there is a process sentinel that notifies the doc-view caller that the conversion has completed) and thus could be either reduced in priority or scheduled for a different time. - Bill ___ gnu-emacs-sources mailing list gnu-emacs-sources@gnu.org http://lists.gnu.org/mailman/listinfo/gnu-emacs-sources
