Formats expand in the run-shell argument?

[japin li]

Hi,

As $subject said, I want to get TMUX directory in .tmux.conf, since I have the following configuration layout.

$ tree ~/.tmux
/home/japin/.tmux
├── personal.conf
├── README.md
├── scripts
│   └── fzf-session.sh
└── tmux.conf

And I have the following setting in tmux.conf

bind J run-shell "tmux popup -E -w 40% -h %30 #{d:current_file}/scripts/fzf-session.sh"

When I execute C-b J, it complains as following:
'tmux popup -E -w 40% -h %30 /scripts/fzf-session.sh' returned 1

According to the documentation [1],  formats are expanded in the run-shell argument.
It seems that #{d:current_file} is empty.  How can I fix this? Or is it possible to get the tmux directory?

You're not running it from a config file, you're running it from a key binding, so there is no current file.

Put this in .tmux.conf and then use #{d:CONFIG_FILE} instead:

setenv -ghF CONFIG_FILE '#{current_file}'

Or you could use #{config_files} instead which is always set, but be careful if you have >1 config file.

Thank you! The #{config_files} works for me, and I have only one config file.
