[gentoo-dev] output from qpkg / gentoolkit without ESC codes

[gentoo-dev] output from qpkg / gentoolkit without ESC codes

[Tim Ruehsen]

Hi,

I redirected output from 'qpkg' into a file. Now it contains these ESC color 
codes (that might are nice on a console). How do I switch ESC codes off?

Or: Where can I find a list of all available packages?

Regards, Tim Ruehsen

qpkg --help tells you to use qpkg -nc

# qpkg --help | grep color
  -nc, --no-color       don't use colors

Also, 'less -R' will let you view files containing control chars correctly.

qpkg -nc (-nc is no color)

Part of the problem with the colors is that Gentoo does not read the
terminfo database for the current terminal type to determine whether or
not color codes are supported or how to display them.  Not all of the
Gentoo tools check where stdout is going either.  This is the kind of
thing that many people would not think important today, but by not
performing these tests we harm our own reputation in the eyes of those
people who are long-time unix hands and know the difference between flash
and function.  The wrong codes sent to the wrong terminal can be truly
catastrophic.

I have heard from people whose opinions I respect that this is a problem
with certain other Linux distributions.  The people in question have not
taken a long look at Gentoo, but they would have the same complaints here
I think.  Fixing this is certainly not top priority, but it is certainly a
professional touch which should not be ignored.

Catastrophic in the same way as trying to use kpackage with apt-install and a colored bash prompt, or just mildly irritating?:)

Catastrophic as in that it us usually a user who winds up doing this and
they wind up with a hosed screen..  Then they come crying to their admin
to fix it for them.  The hapless admin of course doesn't even know what
caused this problem and the equally hapless user can't explain what he did
to cause the problem.

Then of course the sysadmin who has already been driven insane goes on a
killing spree because he just can't take anymore abuse.  ;)


Ever accidentally sent enough binary to the screen to change your console
to the alt charset?  It sucks, but we are able to undo the problem,
whatever it was.  Sending terminal codes a terminal doesn't understand is
how you get these kinds of problems.

I have had proposed that color codes should not be output if the output 
stream is not tty (like ls(1) does with the setting --color=auto). This 
is default with emerge now.

I'm still one of the persons working with non-ANSI terminals and 
expecting colorful output under no circumstances. Maybe that's 
old-fashioned, but maybe the use of ls(1) (e.g.) itself is rather 
old-fashioned. ;->

Kind regards,
k.j.

You're right about not checking where output is going.. one thing Ive noticed recently is runscript (used by init scripts)
doesn't even have a way to control colors via -nc. Only recently has this become something to think about, as I recently
bought a wireless card. now when inserting the wireless card it logs the output from /etc/init.d/net.eth1 start into the
system logs, color codes and all.

example:
Mar 12 03:28:03 [cardmgr] executing: './network start eth1'
Mar 12 03:28:04 [cardmgr] +   [32;01m* [0m Bringing eth1 up...
Mar 12 03:28:08 [cardmgr] +  [A [-7G   [34;01m[  [32;01mok  [34;01m] [0m
Mar 12 03:28:08 [cardmgr] exiting

I looked over runscript.sh, and it looks easy enough to keep it from outputting color; just unset all the variables where teh
color codes are defined.

That is a bug. Please report it in bugzilla.
