history
Project history and usage
Tengo is a small, dynamic scripting language for Go, implemented as bytecode executed on a stack-based virtual machine. The project positions it as fast, secure, embeddable, extensible, and usable either through Go APIs or as a standalone CLI and REPL.
Project history
The GitHub repository was created in January 2019 and the first listed GitHub release, v0.9.1, followed later that month. The project grew around the need for a lightweight scripting layer that Go programs could embed without cgo or external runtime dependencies.
Adoption history
Tengo's adoption is mostly in the Go ecosystem: the README demonstrates embedding scripts through `github.com/d5/tengo/v2`, points to Go package documentation, and links language docs for syntax, object types, runtime types, interoperability, CLI use, and the standard library. Homebrew packaging adds a package-manager path for users who want the `tengo` executable.
How it is used
Developers use Tengo to evaluate expressions, run user-provided scripts with controlled inputs, or ship rule engines, state machines, data pipelines, and transpiler workflows inside Go applications. The CLI also exposes Tengo as a standalone language for scripting and REPL-style use.
Why package nerds care
Tengo matters to package nerds because it is both a library and a command-line language runtime: it packages a tiny VM, standard library, CLI, and docs as a Go-native tool. Its benchmark table compares it with embedded Lua, JavaScript, Starlark, Python, Yaegi, and other interpreters, which is exactly the sort of tradeoff package curators track when choosing embeddable runtimes.
