horizontal pane inside vertical pane with tmuxinator

Question

I want to setup a new window with tmuxinator with the panes like this:

#########
# 1 #   #
##### 3 #
# 2 #   #
#########

i.e., two main-vertical panes with the first one having an horizontal one inside of it, something along the lines of:

windows:
  - editor:
      layout: main-vertical
      panes:
        - gst
        - layout: horizontal
          - gulp
          - python script.py

Is there a simple way to achieve this without using window dimensions as in this answer ? Or some alternative to tmuxinator?

Answer 1

You can get close to that pretty easily with

windows:
   - cli:
       layout: main-vertical
       panes:
         - one:
           - gst
         - two:
           - gulp
         - three:
           - python script.py

produces

#########
#   # 2 #
# 1 ##### 
#   # 3 #
#########

Answer 2

I started to use tmxup instead, here's the solution:

session_name: statuspage
windows:
- window_name: main dev
  layout: main-vertical
  shell_command_before:
    - workon statuspage
  panes:
    - shell_command:
        - python statuspage.py
    - gst
    - pwd
