A tiny hermetic build system.

Source + README: git.ryansepassi.com/xb

Install

go install xb.ryansepassi.com/cmd/xb@latest

Use as a library

xb is also importable as a Go library:

import xb "xb.ryansepassi.com"            // embed the build engine
import "xb.ryansepassi.com/recipe"         // talk to the engine from a Go recipe

See doc/library-api.md (embedder API) and doc/recipe-client.md (recipe-protocol client).
