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. ### Timeline - 2019-01-09: GitHub repository created. - 2019-01-30: v0.9.1 release published. - 2022-09-26: v2.13.0 release published. - 2024-02-29: v2.17.0 release published. - 2025-05-24: v3.0.0 release published. ### Related projects - The README compares Tengo benchmark results with go-lua, GopherLua, goja, starlark-go, gpython, Yaegi, otto, and Anko, and links related projects such as go-fsm and tengo2lua. ### Sources - - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** tengo - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://pkg.so/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://pkg.so/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Language runtime packages](https://pkg.so/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [go](https://pkg.so/brew/go/) - Build dependency declared by Homebrew. - [fzf](https://pkg.so/brew/fzf/) - Shares pkgdb curated category or tags: cli, developer-tools, go. - [hugo](https://pkg.so/brew/hugo/) - Shares pkgdb curated category or tags: cli, developer-tools, go. - [golangci-lint](https://pkg.so/brew/golangci-lint/) - Shares pkgdb curated category or tags: cli, developer-tools, go. - [powershell](https://pkg.so/brew/powershell/) - Shares pkgdb curated category or tags: cli, developer-tools, scripting-language. - [k6](https://pkg.so/brew/k6/) - Shares pkgdb curated category or tags: cli, developer-tools, go. - [shfmt](https://pkg.so/brew/shfmt/) - Shares pkgdb curated category or tags: cli, developer-tools, go. - [overmind](https://pkg.so/brew/overmind/) - Shares pkgdb curated category or tags: cli, developer-tools, go. - [grpcurl](https://pkg.so/brew/grpcurl/) - Shares pkgdb curated category or tags: cli, developer-tools, go. - [d2](https://pkg.so/brew/d2/) - Local package facts share a topical domain.
