Make sure config file is always sourced at startup

[carlosfmesilva]

I have different colors to be used in tmux depending if a variable is defined or not.

A typical use case is when I start tmux in linux console and another one at X environment. For example, I have the following line at ~/.tmux.conf:

if-shell '[ -z ${DISPLAY} ]' 'set-option -g status-style fg=blue,bg=red' 'set-option -g status-style fg=red,bg=blue'

However, I noticed that the line is only executed at the first time the tmux command is launched. The second time tmux is launched, the config file is not sourced (?), thus the colors are not correctly set.

How can I make sure that the config file is always sourced?

If you want the config file to be sourced again you need to start a different server with -L but you will then not be able to switch between sessions (because they will exist in different servers).

You may be better to change it based on TERM, for example something like:

set -g status-style 'bg=#{?#{==:#{client_termname},linux},red,blue}'

Nice thanks. I didn't know that and it seems to work as expected.

But a question remains. Is it possible to achieve the same effect with an variable environment variable. For example, image that a var is defined in ~/.bashrc, and may have value a or b.

The definition:

set -g status-style 'bg=#{?#{==:#{var},b},red,blue}'

Will not work, right?!
