Automate Tabs & Commands in iTerm2

iterm_tabs_and_panes.py

#!/usr/bin/env python3.7

# As described by Daniela Baron -> https://danielabaron.me/blog/iterm-automation/
#
# The contents of a sample commands definition file may look like so:
# [
#   {
#     "title": "usrv",
#     "panes": [
#       {
#         "commands": [
#           "cd /Volumes/Data/workspaces/awesome-app/usrv",
#           "make clean",
#           "make run"
#         ]
#       },
#       {
#         "commands": [
#           "cd /Volumes/Data/workspaces/awesome-app",
#           "code ."
#         ]
#       }
#     ]
#   }
# ]
#
# The above definition creates two panes, in one pane I change to my project directory and launch one of my applications.
# In the other pane I change to my workspace directory and launch Visual Studio code. I use this pane for CI commands later.
