# Layers.ps1 - tweak one layer at a time. # # A theme is a composition of slots (scheme / palette / prompt / font / opacity / # acrylic / font size). These commands change a single slot on top of whatever you # last applied, so you can keep your prompt and just swap the color scheme, etc. # The active composition is remembered in ~/.poshpalette/current.json. $script:CurrentPath = Join-Path $HOME '.poshpalette/current.json' # The composition behind the current look.
