Checks for
stty
in path and uses it, if available, to set terminalwidth (
stty columns 149
). This guarantees that the desired terminalwidth is used for tests when the value comes from
ioctl
, since thathas priority over the
COLUMNS
env var.This addresses an issue where tests for the output of templates that
use the
termWidth
template function would fail when run in certainenvironments - in my case,
bash
running inrxvt-unicode-256color
in Fedora 30 - when the terminal width doesn't match
149
like thetest expects.
