multicolumn xterm output
Anyone heard of a way of splitting your terminal into 2 columns (newspaper style columns) where your eg. 180x49 sized xterm then becomes an emulated eg. 90x98 sized xterm? Preferably supporting the full ansi escape sequences. -- Tim Connors

I think any of tmux, screen, emacs, etc, will do this... -- Brian May <brian@microcomaustralia.com.au>

screen and tmux create new shells for each pane, AFAICS. I want just the one shell, which can be split and the shell subsequently recieves SIGWINCH and $COLUMNS doubles (or halves) and (if bash supported such an environment variable - I can get the equivalent from Term::ReadKey) $ROWS correspondingly halved (or doubles). Emacs can definitely do it, but is not so scriptable in a self contained bash script (hmmm, users might not appreciate me writing an emacs --no-init-file and big elisp bundle just for a small lightweight monitoring display). -- Tim Connors

As you hinted, M-x follow mode RET & comint, shell, compile or similar, poss. with M-x ansi color for comint mode on RET, which gives color sequences only. If you need stuff like tput cup, M-x ansi-term, but I doubt that works sanely with follow-mode. You can't have follow-mode in emacs -batch. The only other idea I have would be to do something wacky like rendering a long, thin xterm offscreen, then grabbing its top and bottom and displaying them side-by-side, using opengl or something (I skipped that class). I was talking to a guy yesterday who was doing something along those lines so he could have floating xterms embedded in his Oculus Rift 3d space.

That's amazing! I read the whole emacs manual a couple of years ago (a quite old versione, really), but I didn't remember anything like that. Do anyone know which version introduced this features? 2015-02-08 1:22 GMT+01:00 Tim Connors <tim.w.connors@gmail.com>:
hmmm. you may be able to do something with groff. or pr, maybe with something like '... | pr --columns=2 -a -l90 -t'
Heh, I like it.
I like it so much too. Thanks all! -- Mick

follow-mode has been there since at least 22. You might try reading the NEWS or ANTINEWS docs that ship with emacs. Emacs has a discoverability problem. (You know, that thing MS Word tried to solve with Clippy?) The best way I've found to discover emacs functionality is to lurk in the IRC channel or ML. That and to study other's init.el's.

Why such an interesting request! What's the purpose? Mick

Too many output lines in a machine status health display. Added a bunch more webservers yesterday that I want to be able to see! Modern screens are wide enough, but the manufacturers are still too cheap to make vertical pixels. -- Tim Connors

Rotate the display 90 degrees, i.e. portrait instead of landscape? -- Brian May <brian@microcomaustralia.com.au>

How about a wide display rotated in both software and physically. A large modern relatively high resolution TV should do a lot on that score. Might also be a lot less trouble to research and set up and configure. I seem to remember something about a utility to resize and reorient the display on the screen, especially linked to multi-headed display environments. Regards, Mark Trickett

Coincidence? Looks like we both sent the same response at pretty much the same time... (seems your clock is fast however, when I got it my clock was still saying 21:48) -- Brian May <brian@microcomaustralia.com.au>

http://mjg59.dreamwidth.org/8705.html TVs apparently tend to be bad for computer use. http://accessories.ap.dell.com/sna/sna.aspx?c=au&cs=audhs1&l=en&s=dhs&~topic... n-up-ultrasharp-monitors FullHd (1920*1080) isn't high resoltion anyway. Dell has a selection of monitors with higher resolutions and a list price of less than $700. Note that RACV members get discounts on the Dell web site so it's even cheaper. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

i think you'll have to modify your status display program to support multi-column or perhaps tabulated output. as i mentioned before, you can do that with curses. or if you don't want any of that fancy text windowing crap, you could write a filter that takes your output as input and prints it as two columns (perhaps as simple as reading the input into a buffer and then printing it with "row[n] row[n+90]" joined on the same line). hmmm. you may be able to do something with groff. or pr, maybe with something like '... | pr --columns=2 -a -l90 -t' craig -- craig sanders <cas@taz.net.au>

Limitation: it does not work interactivelly. It reads all the output, determines the number of columns based on the length of the longest row, and after an EOF it displays the output. In case you'd need interaction, emacs follow-mode is better ;-) -- Mick

i used to use splitvt for this. screen can do it as well. BTW, many programs will use the ROWS and COLUMNS environment variables - so you might be able to set COLUMNS=90 before running the program. actually, the coffee's kicked in and i just re-read your question so ignore all that. you want ONE terminal with two linked columns (bottom of first column extends to top of second column, like a newspaper). screen and splitvt (and tmux and others) create two (or more) completely independent ptys inside the terminal. i don't know of anything that does what you want - it would probably have to be written into the application itself, ncurses can be made to support multiple columns.....and web browsers can do it if the CSS and HTML tell them to. otherwise, if 90x98 is what you really need (and the two columns is just a compromise for a small monitor), you could buy a really big pivot screen and turn it on it's side so that it's tall rather than wide. craig -- craig sanders <cas@taz.net.au>

Helmut Grohne has Python code for a rudimentary multicolumn terminal which runs inside another terminal (BSD licence). It supports some ANSI sequences. http://subdivi.de/~helmut/tcvt/ Glenn -- sks-keyservers.net 0x6d656d65
