Lua API Overview

Lua API Overview

Beez scripts (build.lua) and Lua step callbacks have access to a global beez table. Use it to read configuration, touch the filesystem, fetch URLs, hash artifacts, and more — without shelling out for every task.

All file paths in the Lua API are relative to the project root (the directory that contains build.lua).

Where APIs are available

Context	beez.*	ctx:spawn / wait
Top-level build.lua	yes	no
step({ run = function(ctx) ... })	yes	yes

Error handling

• Invalid arguments and I/O errors usually throw a Lua error.
• beez.net.* REST helpers return { ok = false } for HTTP 4xx/5xx; network failures throw.
• beez.data.validate throws when data does not match the schema.

Example build script

beez.config({
cache= { enabled=true },
})
localversion=beez.env("RELEASE_VERSION") or"dev"localartifacts=beez.fs.glob("dist/**/*")
step({
name="upload",
phase="publish",
scope="release",
run=function(ctx)
beez.archive.compress("dist", "bundle-" ..version..".zip")
localhash=beez.crypto.hash_file("bundle-" ..version..".zip", "sha256")
print("uploading", hash)
return0end,
})
