## What it is
gomacro is an almost complete Go interpreter written in pure Go, providing an interactive REPL with line editing and completion, a scripting mode, a debugger, and Lisp-like macros with generics support. It can also be embedded as a library to add Eval() and scripting capabilities to Go programs.

## Use cases
- experiment with Go code in an interactive REPL
- add Eval() and scripting to a Go application
- debug Go source code interactively
- try out Go generics quickly
- use Go scientific libraries interactively like a notebook
- script in Go without a Go toolchain at runtime

## When to choose
- you want an interactive Go REPL or scripting environment
- you need to embed dynamic code evaluation in a Go program
- you want to experiment with Go generics or macros
- you want a Jupyter-style Go experience via Gophernotes

## When to avoid
- you need full compatibility with all Go features and standard toolchain behavior
- you need maximum performance for production execution
- your project cannot accept MPL-2.0 licensing restrictions

## Facets
- artifact type: library
- maturity: active
- function: interpreter, cli, developer-tools
- domain: programming-languages, developer-tools, education
- platform: go, windows, cross-platform, cli
- tags: go-interpreter, repl, eval, lisp-macros, debugger, scripting, generics, command-line, linux, macos
