Tmux 2.3 problem

[enderahmetyurt]

Hi, I did everthing on README but it cannot display in a project which has git repo. I am using tmux 2.3. How can I fix the problem?

[arl]

Hi,

Did you use the default or custom installation? Can you show me the content of your tmux.conf.

I tested tmux-gitbar on tmux 2.3 and I use versions 1.9 and 2.0 everyday.

[enderahmetyurt]

I used the deafult installation.

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

# hjkl pane traversal
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

set -g base-index 1 # make the windows index start at 1 instead 0
set -g pane-base-index 1 # make the pane index start at 1 instead of 0

# splitting panes
bind | split-window -h
bind - split-window -v

# remap prefix to Control + a
set -g prefix C-a
unbind C-b
bind C-a send-prefix
#
# force a reload of the config file
unbind r
bind r source-file ~/.tmux.conf
#
# quick pane cycling
unbind ^A
bind ^A select-pane -t :.+

# Enable mouse mode (tmux 2.1 and above)
set -g mouse on
set-window-option -g window-status-current-bg colour22

source-file "$HOME/.tmux-gitbar/tmux-gitbar.tmux"
# increase space on right status bar
set -g status-right-length 100
# remove everything on the right (just tmux-gitbar will show up)
set -g status-right ""

Ok thanks, I forgot to ask you, what is your default shell? Bash or something else, as tmux-gitbar is supports only bash for now

[enderahmetyurt]

It's bash

[arl]

Ok i just tried with tmux.conf your provided and tmux 1.9 and 2.3 and the git information is show in tmux status bar. So it must be something else... Can you try to comment the line regarding tmux-gitbar from tmux.conf (source-file),open a tmux session, cd into a git working tree directory and run:

set -x
~/.tmux-gitbar/update-gitbar

Can you see something?

[enderahmetyurt]

Yes. It's working after running set -x ~/.tmux-gitbar/update-gitbar

[arl]

Uhm, i can't seem to see which obvious thing it is, let me sum up:

• update-gitbar, when called, does what it's expected to (so its not a status bar settings problem)
• your $PROMPT_COMMAND could be overwritten somewhat, do you have a non trivial PS1 or PROMPT_COMMAND in .bashrc or somewhere else that might be overwriting it?
• the path to tmux-gitbar, as defined in tmux.conf could differs from the actual path. But it doesn't seem to be the case...

From what i understand, the tmux-gitbar specific $PROMPT_COMMAND, which should simply call ~/.tmux-gitbar/update-gitbar doesn't seem to be installed. May i ask you to post here the output of set -x and echo $PROMPT_COMMAND when you are inside tmux?

[enderahmetyurt]

In my .bashrc I set something for PS1 and PROMPT_COMMAND. I cannot want to paste result of set -x because it's so long :(

I removed PS1 and PROMPT_COMMAND in my .bash_profile and It is fixed now. You are right. They are overwrite tmux-gitbar config.

[arl]

Glad to hear it's working for you now.

Just so you know, you don't have to remove your $PROMPT_COMMAND modifications, just be sure to not overwite what might be previously defined. You probably had a line similar to that in your .bashrc:

export PROMPT_COMMAND=my_prompt_cmd

This will be run by tmux each time it creates a new window, and will reset any previously set $PROMPT_COMMAND.

Instead, if you add something like that in your .bashrc (replace date with whatever was your command):

my_prompt_cmd=date
if ! echo $PROMPT_COMMAND | grep "$my_prompt_cmd" -q ; then
  export PROMPT_COMMAND="$my_prompt_cmd;$PROMPT_COMMAND"
fi

This checks if the my_prompt_cmd command is present in $PROMPT_COMMAND, if yes it does nothing, if no it concatenates it. If you don't do this check, you may end with the same command run multiple times.

$PS1 has nothing to do with tmux-gitbar, so you can let it.

@aurelien-rainone this is my .bash_profile how can I configure it like you pointed. Could you help me?

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
export PATH="$PATH:/usr/local/m-cli"
export PATH="$PATH:/path/to/elixir/bin"

if [ -f "$HOME/.profile" ]; then
  source "$HOME/.profile"
fi

source ~/.git-prompt.sh
source ~/.git-completion.bash

# h is the host name, w the complete path
export PS1="\h\w$ "

##
## Git shortcut
##

g() {
      if [[ $# == '0' ]]; then
          git status
      else
          case $1 in
              fuss)
                  shift
                  git rebase -i HEAD~"$1";;
              *)
                  git "$@";;
          esac
      fi
  }

export CLICOLOR=1
export LSCOLORS=ExFxCxDxBxegedabagacad
export PS1="$PS1\$(git-radar --bash --fetch)"

function prompt {
  local RESET="\[\e[0m\]"
  local BLACK="\[\e[1;30m\]"
  local RED="\[\e[0;31m\]"
  local BLUE="\[\e[1;34m\]"
  local LIGHTBLUE="\[\e[1;35m\]"

  local RVM_GEMSET="$(~/.rvm/bin/rvm-prompt g | tr -d '\n')"

  if [ -n "${RVM_GEMSET}" ]; then
    local RVM_PROMPT="${RED}[$RVM_GEMSET]${RESET}"
  else
    local RVM_PROMPT=""
  fi

  if test -z "$VIRTUAL_ENV" ; then
      local VIRTUALENV_PROMPT=""
  else
      local VIRTUALENV_PROMPT="${RED}[`basename \"$VIRTUAL_ENV\"`]${RESET} "
  fi

  local PATH_PROMPT="${LIGHTBLUE}\w${RESET}"
  local TITLEBAR='\[\e]2;`pwdtail`\a'
  local GIT_RADAR="$GIT_RADAR\$(git-radar --bash --fetch)"

  PS1="${BLUE}\h:${VIRTUALENV_PROMPT}${RVM_PROMPT}${GIT_RADAR} ${PATH_PROMPT}\n${RESET}> "

}

PROMPT_COMMAND=prompt
PROMPT_COMMAND="tab_title ; $PROMPT_COMMAND"

tab_title () {
  echo -n -e "\033]0;${PWD##*/}\007"
}

[arl]

From what i understand, your prompt function is what sets up your prompt (colors, git-radar, etc.), but it should not be included in the $PROMPT_COMMAND variable, I now it's misguiding... Only tab_title should be added/concatenated to $PROMPT_COMMAND.

So i would remove both lines starting with PROMPT_COMMAND= and adds this at the end of the file (after tab_title definition):

# check if tab_title has already been installed as PROMPT_COMMAND
if ! echo $PROMPT_COMMAND | grep "tab_title" -q ; then
  export PROMPT_COMMAND="tab_title;$PROMPT_COMMAND"
fi

# defines my bash prompt
prompt

[enderahmetyurt]

I removed

PROMPT_COMMAND=prompt
PROMPT_COMMAND="tab_title ; $PROMPT_COMMAND"

and set as you say but now bash cannot change the RVM ruby gemset name.

[arl]

Ok, so prompt does need to be part of the $PROMPT_COMMAND, this should do the trick:

if ! echo $PROMPT_COMMAND | grep "tab_title;prompt" -q ; then
  export PROMPT_COMMAND="tab_title;prompt;$PROMPT_COMMAND"
fi

Ok thank you for your all help 🍰 🍵

You're welcome
