OS segment: display WSL distro name (not OS)

Description

I run a number of WSL distros of the same type (Ubuntu 20.04 mainly) for different projects by cloning and renaming my base distro (see instructions here). It would be very useful to be able to display the WSL distro name as a segment rather than just the OS name/logo. Is this possible? Many thanks.

Environment

• Oh my Posh version: 3.96.0
• Theme: negligible
• Operating System: Ubuntu 20.04.2 LTS (5.4.72-microsoft-standard-WSL2)
• Shell: bash
• Terminal: Windows Terminal 1.5

@charlesroper do you know a command to get this information from within the WSL instance?

@charlesroper sounds like this is held in the environment variable $WSL_DISTRO_NAME which you can confirm using the command echo $WSL_DISTRO_NAME

With that in mind, you should be able to display this in your prompt by adding a envvar segment to your theme. envvar docs here

Superb, thank you! I didn't think of using an environment var. I've customised my local copy of the negligible theme to include the distro name. Screenshot and content of theme file below.
