# Zsh completion for CCS (Claude Code Switch)
# Compatible with zsh 5.0+
#
# Installation:
#   Add to ~/.zshrc:
#     fpath=(~/.zsh/completion $fpath)
#     autoload -Uz compinit && compinit
#     source /path/to/ccs/scripts/completion/ccs.zsh
#
#   Or install system-wide:
#     sudo cp scripts/completion/ccs.zsh /usr/local/share/zsh/site-functions/_ccs

# Set up completion styles for better formatting and colors
# Color codes: 0;34=blue, 0;32=green, 0;33=yellow, 2;37=dim white
# Pattern format: =(#b)(group1)(group2)==color_for_group1=color_for_group2
# The leading '=' means no color for whole match, then each '=' assigns to each group
