Module render 

Per-instance values substituted into a file the project commits.

Ports reach a command as {{ports.x}} and as an env var. Most tools do not take them that way: Supabase reads supabase/config.toml, Expo reads .env, Compose reads compose.yaml. Without this, every project that hits it writes the same config rewriter inside its prepare hook.

There is no template file. port = 54321 is not a placeholder, it is the project’s working default — a clone without newgit still starts on it. newgit substitutes into the committed content and writes the result into one workspace. See Render in newgit-v1-mvp.md.

Structs

AppliedReplacement

A replacement with its template already rendered, so the inverse is exact.

RenderRecord

What a render actually did, recorded on the binding record so capture can reverse it without re-deriving the values from a definition that may have been edited since.

RenderSpec

One file a resource renders per-instance values into.

Replacement

A literal substitution. find is never a regex: a pattern language reintroduces the “did it match what I meant” doubt that Replacement::count exists to remove, and it would leave the inverse undefined.

Functions

apply

Substitute into committed, the file’s committed content — never what is currently on disk.

reverse

Undo a render: rewrite this instance’s values back to the committed ones.

substitute

Apply already-resolved replacements as one simultaneous batch, enforcing each rule’s declared match count against the input.

validate_disjoint

Two resources rendering the same path is a config error, not a merge: they would race, and the second would render over the first’s output and fail its own match check for reasons nothing in the definition explains.
