I think the quoting and controling syntax is wrong. The following string works here fine in a Gnome terminal.

Quoted 1 line

echo -ne "\033[2msomething\033[0m other text\n"

Or with a underline and in green.

Quoted 1 line

echo -ne "\033[4;32msomething\033[0m other text\n"

You need to set up the starting thing with '\033["$foo-color"' and finally switch at the end to the to the default back '\033[0m'

More info around colors in the Bash can be found on
http://www.tldp.org/HOWTO/Bash-Prompt-HOWTO/x329.html
But that's only for the Bash!

The change Fran?ois is suggesting is for the terminal title window, it does not change anything about coloring.

The above commands you gave do not change anything in the title bar for me, nor in Konsole, nor in gnome-terminal. The second command does show the green underlined text in both terminals, but as said the title bar is unchanged.

$ env | grep  "SHELL\|TERM"
TERM=xterm
SHELL=/bin/bash
COLORTERM=gnome-terminal

env | grep "SHELL\|TERM"

Although I like the idea, it does not work for me. I'm running Linux Mint, with a Konsole terminal. The above does nothing at all. I also tried manually:

echo -ne "\033]0;something\007"

but it doesn't change a thing.
It does work in gnome-terminal. I haven't tested in other situations.

Could you have a look at Konsole?

I know that Gentoo has this feature for its portage package installation/compilation tool. When you run 'emerge', the titles are constantly updated with the package that is being handled, also in Konsole. You may be able to find out what the 'right way' is based on their sources.

Thanks,
Thomas

Thomas,

at the end of the command, the initial title is restored, so try something like :

$ echo -e "\033]2;Foo\007" && wait

Are you sure this works for you with emerge? I RTFM'ed it and according to
the konsole manual, you have to add '%w' to the tab title string to get the string set by the shell. Perhaps Gentoo simply sets the default tab title string to something including %w.

It does work for emerge, but it seems you are right: the default tab title in Gentoo is set to %w (I didn't set it explicitly). I tried Francois' patch on a non-gentoo system before (didn't work for Konsole) but after explicitly setting %w in the tab title it also works there. So that issue is cleared out.

However, while testing again, I noticed an annoyance: if the build process stops prematurely, for example because the build fails or the user interrupts it, the last tab title remains. I would much prefer that we can cleanly restore this no matter how buildroot/make stops.

Currently it is indeed, but that could easily be fixed by adding an extra such print at the end.

I think this patch is only really suitable for people who have

something similar in their PS1. Otherwise it will just mess up your window title.

Quoted 2 lines

Also, it should only be done if $TERM == xterm, otherwise you get

annoying stuff when running buildroot from a text console. And in fact, the same is true of the colouring itself, so we don't get these annoying escape characters in log files and continuous integration web interfaces.

Agreed.

Best regards,
Thomas

A print of what? An empty string? Then your window won't have a title
anymore... There is no way to save the previous window title, so I really think that if PS1 doesn't set the window title, then buildroot shouldn't either.

Other programs, like gentoo portage, are able to restore the window title correctly. I don't know how, but it is possible.

That said, although I like the idea of easily seeing which package is currently building, I also think it should either be perfect or not be at all.

As an alternative, is it possible to count the number of make targets / packages remaining, and show that in the MESSAGEs? Then you only have to scroll up to the last message to get an idea...
