Features

  • Format-on-save for Teal (.tl) files.
  • Fast session daemon with no startup cost on save.
  • Zero config when ceru is on your PATH. One setting (cerulean.cliPath) if it isn't.
  • Coexists with pdesaulniers.vscode-teal, install both.

Requirements

The ceru binary must be on PATH, or cerulean.cliPath must point at it. Run luarocks install cerulean to install it. See Cerulean repo for documentation.

Verify the install:

ceru --version

  2. Open a .tl file, make changes, and save.
