# Claude Code Statusline — dark theme
# https://gist.github.com/mikaturunen/784c3eedb2f808c610d15b971b8c97b3
#
# Shows: model · git branch · cost in EUR · context remaining
#        rate limits: 5-hour and 7-day windows (Claude.ai subscribers only)
#
# ── INSTALL ───────────────────────────────────────────────────────────────────
#
#  1. Download the script:
#
#       curl -fsSL https://gist.githubusercontent.com/mikaturunen/784c3eedb2f808c610d15b971b8c97b3/raw/statusline.sh \
#         -o ~/.claude/statusline.sh && chmod +x ~/.claude/statusline.sh
#
#  2. Add to ~/.claude/settings.json  (create the file if it doesn't exist):
#
#       {
#         "statusLine": {
#           "type": "command",
#           "command": "~/.claude/statusline.sh"
#         }
#       }
#
#     If you already have a settings.json, add just the "statusLine" key
#     alongside your existing keys.
#
#  3. Restart Claude Code — the statusline appears immediately.
#
#  Requirements: bash, jq, git, awk  (all standard on macOS and Linux)
