Embeddable Scripting Languages

24 projects

Embedding a scripting language lets users or operators change behavior without recompiling your Go program: rules engines, plugins, configuration logic, game scripts and user-defined filters. Options range from small expression evaluators that cannot loop, through sandboxed configuration languages, to full JavaScript and Lua interpreters. Most entries are written in pure Go, so they need no cgo.

expr evaluates expressions with optional static type checking and is a common choice for business rules, and Google's cel-go implements the Common Expression Language used in Kubernetes and elsewhere. gval is another customizable expression language. dop251/goja is an ECMAScript 5.1+ engine in pure Go with some newer features, used by tools such as k6. yuin/gopher-lua implements Lua 5.1, Shopify's go-lua ports Lua 5.2, and golua binds the C Lua API. google/starlark-go implements Starlark, the Python-like language from Bazel with deterministic, hermetic evaluation. tengo is a bytecode-compiled scripting language designed for Go. FrankenPHP is a PHP application server that embeds PHP in Go.

Prefer the most limited option that works. For filters and rules, expr or CEL are safe because they are not Turing complete. For configuration with functions, Starlark is deterministic and sandboxed. Choose goja or gopher-lua when users need general-purpose scripting, and always set execution limits so a script cannot hang your service.
