gentoo tcsh colour scheme [SOLVED]

mrpringle · 2009-08-05 09:44:29

Hey,
Gentoo came with a nice terminal colour scheme and prompt, and I would like to have a similar setup on my laptop running arch linux.

I downloaded the gentoo-bashrc package from the AUR and copied the bashrc file to ~/.bashrc, but the colour scheme and prompt doesn't appear unless I start the bash shell. The problem being I use tcsh.

Does anyone know how to make the same prompt appear if I use any shelll? I don't know how it worked under gentoo, but the bashrc prompt seemed to be inherited by all the shells.

For anyone interested I did some digging and came up with a solution.

I had a look (on my gentoo box) at a file named csh.cshrc and found it had some code which seemed to produce the colourful custom prompt. I extracted the parts of code which created the prompt and placed it in my ~/.tcshrc file. I could have overwritten Arch Linux's csh.cshrc file, but then if I ever upgraded tcsh it would be lost.
As a side note the tcsh.tcshrc file that came with Arch Linux has no custom prompt or colourisation, however it claims to be taken from the gentoo distribution :-)

I then had a couple of issues. The csh.cshrc file referenced /usr/bin/dircolors, which is in the /bin directory under Arch. It also referenced a DIR_COLORS file which modifies the colour coding for different extensions when 'ls' is run. This didn't exist on my Arch PC, so I copied it across from my gentoo PC.

Here is the .tcshrc file and DIR_COLORS file if anyone uses tcsh or csh and wants a colourful prompt.

Save as ~/.tcshrc

# Set some variables for interactive shells
if ( $?prompt ) then
    if ( -r /etc/DIR_COLORS ) then
        if ( $?TERM ) then
            set colour = `/bin/egrep "^TERM ${TERM}"'$' /etc/DIR_COLORS`
        endif
    endif

    # Set a Gentoo-ish prompt and setup colourful stuff if we have colour
    set promptchars = "%#"
    if ( $?colour ) then
        if ( "$uid" == "0" ) then
            set prompt = "%{\033[0;1;34m%}(%{\033[0;1;31m%}%m%{\033[0m%}:%{\033[0;1;34m%}%c3%{\033[0;1;34m%}) %{\033[0;1;31m%}%#%{\033[0m%} "
        else
            set prompt = "%{\033[0;1;34m%}(%{\033[0;1;32m%}%m%{\033[0m%}:%{\033[0;1;34m%}%c3%{\033[0;1;34m%}) %{\033[0;1;32m%}%n%{\033[0;1;32m%}%#%{\033[0m%} "
        endif

        # Enable colours for ls, etc.  Prefer ~/.dir_colors
        if ( -f "${HOME}"/.dir_colors ) then
            eval `/bin/dircolors -c "${HOME}"/.dir_colors`
        else if ( -f /etc/DIR_COLORS ) then
            eval `/bin/dircolors -c /etc/DIR_COLORS`
        endif

        alias ls 'ls --color=auto'
        alias grep 'grep --color=auto'
    else
        if ( "$uid" == "0" ) then
            set prompt = "(%m:%c3) %# "
        else
            set prompt = "(%m:%c3) %n%# "
        endif
    endif
    unset colour
endif

Save as /etc/DIR_COLORS

Hello Mrpingle!

I think It can be solved with other terminals too, just with setting the desired shell config.
