tmux

I followed Getting 256 colors to work in tmux:

• I have alias tmux='TERM=xterm-256color tmux' in ~/.bashrc
• and also set-option -g default-terminal "screen-256color" in ~/.tmux.conf

In konsole:

$ echo $TERM
xterm

In tmux:

$ echo $TERM
screen-256color

Still colors doesn't work in tmux:

boris@vasilisa:~$ PROMPT_GREEN=`tput setf 2`
boris@vasilisa:~$ PROMPT_RED=`tput setf 4`
boris@vasilisa:~$ PROMPT_BLACK=`tput setf 8`
boris@vasilisa:~$ PS1='\[$PROMPT_RED\]\w\[$PROMPT_GREEN\]:\[$PROMPT_BLACK\] '

Results in a black-and-white color prompt. Also no color with ls.

screen

I have force_color_prompt=yes in ~/.bashrc. Still:

boris@vasilisa:~$ PROMPT_GREEN=`tput setf 2`
boris@vasilisa:~$ PROMPT_RED=`tput setf 4`
boris@vasilisa:~$ PROMPT_BLACK=`tput setf 8`
boris@vasilisa:~$ PS1='\[$PROMPT_RED\]\w\[$PROMPT_GREEN\]:\[$PROMPT_BLACK\] '

Doesn't make prompt colorful. But in contrast to tmux — ls lists files with color.

So

I guess tput setf just shouldn't work with terminal multiplexers?

Edit

I had to change setf to setaf, and also change the color codes:

PROMPT_BLACK=`tput setaf 0`
PROMPT_RED=`tput setaf 1`
PROMPT_GREEN=`tput setaf 2`
PS1='\[$PROMPT_RED\]\w\[$PROMPT_GREEN\]:\[$PROMPT_BLACK\] '

I don't need to aliase tmux, setting

set-option -g default-terminal "screen-256color"

in ~/.tmux.conf is suffice.

So I put

# colorful prompt
PROMPT_BLACK=`tput setaf 0`
PROMPT_RED=`tput setaf 1`
PROMPT_GREEN=`tput setaf 2`
PS1='\[$PROMPT_RED\]\w\[$PROMPT_GREEN\]:\[$PROMPT_BLACK\] '

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto --group-directories-first'
    alias dir='dir --color=auto'
    alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'
fi

# man pages with color!
export LESS_TERMCAP_mb=$'\E[01;31m'
export LESS_TERMCAP_md=$'\E[01;31m'
export LESS_TERMCAP_me=$'\E[0m'
export LESS_TERMCAP_se=$'\E[0m'
export LESS_TERMCAP_so=$'\E[01;44;33m'
export LESS_TERMCAP_ue=$'\E[0m'
export LESS_TERMCAP_us=$'\E[01;32m'

# enable colors:
force_color_prompt=yes

in both: ~/.bashrc and ~/.bash_login and then colors work in tmux.
