Crashes on vttest
Crashes on vttest 1 (cursor movements). Most other tests need work too.
There is some discussion on alacritty's vttest issue thread that may be useful. https://github.com/jwilm/alacritty/issues/240
This is really useful, thank you. I wasn't aware of vttest until now. I'll give it a run tomorrow.
No problem, I am always happy to see new terminals come up. Yours is quite popular, hope it fares well. FYI vttest is a bit of a bear to get through, but once done you will know the vt100/vt102 manuals inside and out. :)
Yep, I know this is going to be painful, but hopefully worth it. I'll probably split this into issues for each test, and possibly reimplement vttest internally so I can automatically test it passes on builds.
Oh, and I've just realised you have to switch to 80x24 before you attempt these, for anyone trying it.
Easiest way to do that is ctrl + shift + d/cmd + d and resize.
I crashed the first time too. :) (I crashed again long after passing vttest when I logged into a VMS system and ran the LSE editor. Man those DEC guys were brutal...)
Well, I'm no longer crashing on my test branch, but there's a long way to go.
One thing I've noticed is lots of \x1b[1g and \x1b[2g which I cannot find documented anywhere. The docs mention 0g meaning clear tab (I think this means move back to the last tab stop?) and 3g which means clear all tabs, but not those other two. Have you found a good resource that goes into detail on these codes? Most places just say "Tab Clear" which doesn't explain the expected behaviour at all.
In fact the VT100 manual says "Any other parameter values are ignored." so I guess vttest is making sure I ignore them.
Hmm, yes that is what my emulator does: unknown parameters are silently ignored. Also, if you haven't already seen xterm's control sequences page: https://invisible-island.net/xterm/ctlseqs/ctlseqs.html . I find it handy in that it shows VT220/320/420 sequences in one place, a little easier than searching through those manuals separately.
The zombie rises again. :) 0.0.10 darktile release crashes on the VT102 tests (test 8).
