Discussion on: Can I see your terminal?

[Dave Jacoby]

It helps if you have Font Awesome set up on your system.

This needs cleaning up. As pasted from my prompt.sh

# prompt.sh

# the unified prompt for Dave Jacoby, based on system settings
# and capabilities.

# if a capability is absent for an entry, such as TaskWarrior
# or ACPI, the prompt will drop that in favor of entries it
# can handle.

# Tasks

#   * I have partially added Font Awesome to the prompt,
#     especially for the buttons. I need to more fully 
#     integrate FA fonts. For example, with TaskWarrior 
#     icons

# TASK WARRIOR INTO MY PROMPT
# this part is just fun-with-utf8
