We have the same document :) But it says that to be compliant (it says exactly that it would be a "limited conformance"), one must say which parts of it are implemented, or are not.

Vendor-specific extensions have an official place in the current standard. But as you said, the standard is huge, so just having a full implementation, or one without deprecated stuff (as modes) would be a probably more than what I will need :D But it could really be useful. > terminals are now implemented in software, it would be perfectly possible > to implement very advanced functionality such as SVG-compatible vector > graphics and OpenGL in terms of the escape command sequences (or an > equivalent alternative). Sounds interesting but I still see terminals as interfaces for text only, so I must admit I have some doubts about the usefulness of supporting SVG rendering. Also, the standard sounds like designed to be efficient in the use of bandwith, it uses text (numbers in fact) for parameters, but other stuff is not really text (but often have textual representations, of course), unlike SVG where stuff sounds really linked to character encoding (and in my opinion, not really efficient in terms of bandwidth usage like all XML stuff, but that's only my personal opinion). But I do not think it is a problem, since Ecma-48 voluntarily let spaces for further extensions. I guess the better solution here would be to use a plug-in system: having a basic standard set hard-coded (say, VT100, to mimic other terminals), and other sets + extensions implemented as plug-ins (dynamic or not is not the question here) so that they would be easier to implement and add/remove. > I've had plans to write a "new" terminal emulator for several years; A huge work for which I have no real clue about where to start. And I also have some other stuff to do before even trying to think about such a project :) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
