Useful development tools

This readme contains some hints on how to set up some optional development tools.

ccls

ccls is a c/c++ language server. It requires some setup to work well. There are different ways to do it but here's what works for me:

  1. Make a common parent directory for all your common neon projects. (for example, ~/src/neondatabase/)
  2. Go to vendor/postgres-v15
  3. Run make clean && ./configure
  4. Install bear, and run bear -- make -j4
  5. Copy the generated compile_commands.json to ~/src/neondatabase (or equivalent)
  6. Run touch ~/src/neondatabase/.ccls-root this will make the compile_commands.json file discoverable in all subdirectories

With this setup you will get decent lsp mileage inside the postgres repo, and also any postgres extensions that you put in ~/src/neondatabase/, like pg_embedding, or inside ~/src/neondatabase/neon/pgxn as well.

Some additional tips for various IDEs:

Emacs

To improve performance: (setq lsp-lens-enable nil)
