I'm told the following bit of code doesn't work on Solaris:

# A Unix savvy method to fetch the console columns, and rows.
def terminal_size
`stty size`.split.map { |x| x.to_i }.reverse
end

HighLine makes use of this method as does Capistrano by extension, so
we need find a portable solution.

Can anyone provide an equivalent technique that works on Solaris?

Thanks.

Ruport vendors this chunk of code, so sorry for the 'me too', but me too!

If it helps, the output from stty looks like the following:

-bash-3.00# stty size
unknown mode: size
-bash-3.00# stty
speed 38400 baud; -parity
rows = 24; columns = 80; ypixels = 0; xpixels = 0;
eol = -^?; eol2 = -^?; swtch = <undef>; flush = -^?; lnext = -^?;
brkint -inpck -istrip icrnl imaxbel onlcr tab3
echo echoe echok echoctl echoke iexten

Had a quick look at the man pages, there doesn't seem to be an alias
for size.

The man pages are also on the Sun site here: http://docs.sun.com/app/
docs/doc/816-5165/6mbb0m9tb?a=view

Hope this is of some help.

On FreeBSD:

[alex@panama ~/noodling/rubinius]$ stty
speed 38400 baud;
lflags: echoe echoke echoctl pendin
oflags: -oxtabs
cflags: cs8 -parenb

No rows or columns. How about stty -a?

[alex@panama ~/noodling/rubinius]$ stty -a
speed 38400 baud; 62 rows; 157 columns;
lflags: icanon isig iexten echo echoe -echok echoke -echonl echoctl
-echoprt -altwerase -noflsh -tostop -flusho pendin -nokerninfo
-extproc
iflags: -istrip icrnl -inlcr -igncr ixon -ixoff ixany imaxbel -ignbrk
brkint -inpck -ignpar -parmrk
oflags: opost onlcr -ocrnl -oxtabs -onocr -onlret
cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow
-dtrflow -mdmbuf
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
eol2 = <undef>; erase = ^?; erase2 = ^H; intr = ^C; kill = ^U;
lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q;
status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W;

Leave it to BSD to do everything backwards!

How's this:

[alex@panama ~/noodling/ruby]$ ruby t.rb
[157, 62]
[alex@panama ~/noodling/ruby]$ cat t.rb
def terminal_size
%r{([^;]*rows[^;]*([^;]*columns[^;]*}.match(`stty
-a`)[1..-1].map{|i| i.gsub(/\D/, '').to_i}.reverse
end

puts terminal_size.inspect


'Scuse the line break, but it works on FreeBSD, Linux and Cygwin+OCI...

Here's my stab at a cross-platform implementation:

def terminal_size
if /solaris/ =~ RUBY_PLATFORM
output = `stty`
[output.match('columns = (\d+)')[1].to_i,
output.match('rows = (\d+)')[1].to_i]
else
`stty size`.split.map { |x| x.to_i }.reverse
end
end

I did a quick test on Solaris (9 and 10), FreeBSD and Linux, and got
the same results in every case. (No guarantees on AIX, HP-UX, etc.)

I assume the current code (using `stty size`) works on FreeBSD. Does
it not?

It does. I was aiming at something that would work everywhere.
