# IMPORTANT: Add this to the END of your fish config (~/.config/fish/config.fish):
# whi init fish | source
# This must be at the END so whi captures your final PATH after all modifications.
# Also remove any old "# whi: Load saved PATH" sections from your config -
# saved PATH loading is now included at the top of this integration script.
# Or run in the current shell:
# whi init fish | source
# Prompt integration: whi automatically adds "[name]" or "[name:locked]" to the right prompt.
# Customize by editing __whi_prompt or overriding fish_right_prompt after sourcing if
# you prefer a different placement.
