Precompiled.Match (precompiled v0.2.0)

Copy Markdown View Source

The key: when a precompiled build may stand in for a local compile. Pure functions over the project's lock, the manifest entry and the toolchain, so every rule is testable without a network or a build.

Summary

Types

ctx()

Functions

candidate?(dep, lock, except, tooling \\ nil)
compile_env_from_app(app_path)
compile_env_ok(items, config)
files_hash(entry)

The identity of a build's bytes: sha256 over its files' path, sha256 and mode, in path order. Two manifest entries with the same hash install the same files. nil for an entry with a malformed file list, or a path with a NUL or newline, which could pass one file off as another's line.

nerves_children(lock)

Lock-closure children of nerves; nerves_bootstrap recompiles them whenever it compiles nerves.

select(manifest, ctx)
tooling?(name)
