setup.sh

#!/usr/bin/env bash
# setup.sh — first-run setup for Code-RAG.
#
# What it does:
#   1. Copies application.ini.example -> application.ini if the real file
#      does not yet exist, and fills the shared secret with a random UUID.
#   2. Copies rag-projects.json.example -> rag-projects.json (only the
#      first time — your edits are never overwritten).
#
# Safe to re-run. If your application.ini or rag-projects.json already exist,
# they are left strictly alone.
#
# Requires: bash, python3.

Setup complete. Next steps:
  1. Edit src/main/backend/rag-projects.json to point at your real code roots.
  2. Make sure PostgreSQL (with pgvector) and Ollama are running. See Running.md.
  3. Start the server:  ./bld -v start
  4. Register the MCP server with Claude Code (see Running.md §5).
  5. The shared secret you need is in src/main/backend/application.ini under
     RAGMCPSharedSecret.
