Override terminal width #606
Description
I wasn't sure if this should go here or in terminal_size but I think the latter is a minimal utility, and this feature is more context specific?
There are situations where I want to override the terminal size/wrap width. For instance, when capturing wrapped command output for a fixed-width document, or doing multi-column output (e.g. with diff -y) etc. Or alternatively, setting it to a very high number to effectively disable wrapping.
I think the COLUMNS environment variable is fairly standard for this in linux, e.g. ncurses has this documentation https://invisible-island.net/ncurses/man/ncurses.3x.html#h3-COLUMNS (used to override terminfo data). https://linux.die.net/man/1/resize, also it looks like vim reads that variable. https://linux.die.net/man/1/tput reads it too. E.g.:
export COLUMNS=80
./run_my_program
It'd be great if this supported that as well when using the terminal_width feature... or maybe it does and I just messed up updating my packages. I couldn't find any discussions about this elsewhere though.
