Verified on the Mac, and three of the four things it taught were the
opposite of what the code assumed.
RunCommandAsShell is false. Under *true* Terminal takes the whole command
string as the name of a program and the window reads "Command not found:
MESHTERM_REOPENED=1 / Could not create a new process and open a
pseudo-tty". The key's name says otherwise; the measurement wins.
The environment rides on /usr/bin/env rather than on a VAR=value prefix,
for the same reason. env is a real executable, so the line is valid as a
bare argv and as a shell command both, and the window cannot land on that
message however Terminal decides to read the string.
Terminal names an imported settings set after the FILE, not the name key
inside it -- and re-importing the same bytes reuses that profile, while
different bytes under the same filename add "MeshTerm 1", then
"MeshTerm 2". Opening one file four times, three identical and one a word
apart, left exactly two profiles. So the command cannot live in the
profile: it carries argv and the reader's MESHTERM_* variables, and a
profile per command line would fill their settings list with junk only
they can remove. The variable part moved behind a fixed path instead --
the profile says ~/.meshterm/launch.sh and never changes, and the script
underneath says whatever this launch needs.
Three launches with three different command lines now leave one profile
named MeshTerm, the window drawing CascadiaMonoPL-Regular at 13pt on
opaque black at 80x30, with the app running in it. The reader's default
profile is still theirs, blur and all.
shellExitAction 1 while here: tidy the window away on a clean exit, keep
it on a crash, because a crash nobody sees is a bug report nobody writes.
