t_make

Build and Run a Pipeline File

Reads, parses, evaluates, and builds a T pipeline script path. This is a high-level orchestrator often used from the interactive T REPL to trigger full builds.

Signatures

• Named Signature:

  t_make(filename = "src/pipeline.t", nix_options = [...], verbose = 1, failfast = false)

• Positional Signature:

  t_make(filename, nix_options, verbose, failfast)

Parameters

• filename (String): (Optional) The pipeline build script path. Must be "src/pipeline.t". Defaults to "src/pipeline.t".
• nix_options (Dict): (Optional) A dictionary of Nix orchestration options:
  • max_jobs (Int): The maximum parallel build jobs. Maps to --max-jobs.
  • max_cores (Int): The maximum number of cores per job. Maps to --cores.
  • cache (String): Cachix cache name to use as a binary substituter.
  • targets (String|List[String]): Specific node names to build. Maps to -A.
  • force (Bool): Force rebuilds even if cached. Maps to --check.
  • dry_run (Bool): Plan and show what would be built without executing. Maps to --dry-run.
  • builders (String): Nix remote builders configuration.
  • keep_env (String|List[String]): Environment variables to pass through to the sandbox.
  • sandbox (Bool|String): Nix isolation sandbox policy ("relaxed", "strict", "none").
• verbose (Int): (Optional) The Nix build verbosity level. 0 is quiet, values > 0 enable build output and failure diagnostics.
• failfast (Bool): (Optional) If true, stops immediately on evaluation/build errors. Defaults to false.

Examples

Using named parameters:

t_make(nix_options = [max_jobs: 4, dry_run: true])

Using the positional signature:

t_make("src/pipeline.t", [max_jobs: 8], 2, true)
