From c9c70d624125dfa25461f7586b9bbd2bc7ff2372 Mon Sep 17 00:00:00 2001 From: Tyler Hall Date: Sun, 30 Jun 2013 16:16:19 -0400 Subject: terminal: Run command using a wrapper script Some terminals may not pass the environment into the child process. This is true when using "tmux split-window." If tmux is already running, it will start the command with the tmux session environment, ignoring the environment where the command was issued. This could possibly be worked around when launching tmux by injecting variables into the user's session environment or adding the variables to the "update-environment" tmux setting. However, both methods would permanently alter the user's session, which is undesirable. By using a wrapper script, we have full control over the final environment. Replace the env dictionary with an empty data smart that will contain the exported variables and a wrapper function that execs the original command.
