environment option not work on PATH variable

[joselbr2099]

I am trying to load the PATH variable in a tmuxp session and this variable should be available in any new window of the session:

global_options:
default-command: /bin/bash 
environment:
  EDITOR: /usr/bin/vim
  PATH: ${PATH}$HOME/.config/myproj/
session_name: myproj
windows:
- window_name: main-dev
  focus: true
  layout: horizontal
  panes:
  - shell_command:
    - printf '\033]2;%s\033\\' 'Editor' 
    focus: true

${PATH}$HOME/.config/myproj/ it only loads in the current window but when a new window is created the variable disappears
while EDITOR is loaded in any new window and does not disappear

Step 2: Provide tmuxp details

• Python 2.7.6
• system PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/opt/bin:/usr/bin/core_perl:/usr/games/bin:/home/robot/.local/bin:/root/.gem/ruby/2.3.0/bin:/opt/android-sdk/tools:/opt/android-sdk/platform-tools:/opt/android-sdktools/:/opt/android-sdkplatform-tools/:
• tmux 2.9a
• tmuxp 1.5.1
• tmux /usr/bin/tmux
• tmuxp ~/.local/bin,
• libtmux ?
• shell bash
• output of

    `myproj: 2 windows (created Tue May 14 01:26:02 2019) (attached)`,

Step 3: Describe your environment

• Architecture: x86_64 GNU/Linux
• OS version: Arch Linux 5.0.11-arch1-1-ARCH

Step 4: Describe the problem:

Steps to reproduce:

1. create dev.yam file
2. tmuxp load dev.yaml
3. in the current window: echo $PATH and echo $EDITOR
   the variable $HOME/.config/myproj/ appears
   $EDITOR show "vim"
   ctrl+b+c //new window
   in new windows: echo $PATH and echo $EDITOR
   the variable $HOME/.config/myproj/ does not appears
   $EDITOR show "vim"

Observed Results:

• the $HOME/.config/myproj/ variable is not displayed in new windows

Expected Results:

• that the $HOME/.config/myproj/ in PATH variable can be accessed from any created window, just like the variable EDITOR

I had the same issue with 1.5.4. Then I upgrade to 1.6.2 to see if it was fixed but no :( but I found that doing the following works:

session_name: myproject
shell_command_before:
  - PATH=$PATH:$(pwd)/bin/
  - '[ -d `pipenv --venv` ] && source `pipenv --venv`/bin/activate && reset'
  - nvm use default
windows:
...

That is my workaround, not sure how accurate that is but it works for me :) I hope it can be helpful for someone.

Note: As you can see I'm using pipenv and nvm here, and I need to place the PATH instruction first otherwise it will get overwritten by pipenv and nvm

@boertel Happy that you were able to find a workaround

For both you and @joselbr2099 (and anyone else who bumps into this):If we had this recreated in a test PR (to recreate the issue), that would be ideal (I could write a fix for it)
