AH! The days before widespread revision control! HPGL looks like it would fit the bill, for line drawings, anyway. If I could get an off-the-shelf editor to read it and write it, anyway. It dose seem to be more like object code than source code, so to speak. It would work with revision control if I could put in newlines instead of semicolons. Or modify the revision control system to accept semicolons and treat them as it now handles newlines. Really, it should be possible for a revision control to understand file types and know what's special about them. One workaround is to write some code that transforms between a revision- friendly HPGl and regular HPGL in both directions, to use the revision- friendly HPGL as checked-in source code, and to turn an existing editor into one for this format by a shell command that converts back and forth ... Come to think of it, this might work with a lot of the other graphics file formats. As long as they don't contain arbitrary identifiers that change with every edit. I must investigate. I've faced the same problem with word-processor file formats, actually. At the moment the solution seems to be systems like markdown and asciidoc. But it's easier there because marked-up ASCII text is a lot closer to the format in which the final document is presented. It's still text, after all. There's opportunity for some low-level research here. -- hendrik -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
