## Project history and usage

Evans is a command-line and interactive gRPC client built for inspecting, calling, and scripting gRPC APIs from a terminal.

### Project history

The project describes its motivation as making gRPC clients easier to use than existing tools. Its README splits the design into REPL mode for manual API inspection and CLI mode for scriptable, one-command calls.

### Adoption history

The project distributes binaries through GitHub Releases, recommends Homebrew on macOS, publishes a container image, and supports `go install`, placing it in the usual packaging paths for Go-based infrastructure CLIs.

### How it is used

Users point Evans at proto files or use gRPC reflection, then call services interactively in the REPL or pipe JSON through CLI mode. A project-root `.evans.toml` can provide defaults such as proto file, package, and service.

### Why package nerds care

Evans matters to package-manager users because it packages a repeatable gRPC debugging workflow: shell-friendly JSON in CLI mode, completion in REPL mode, reflection support, Docker images, and Homebrew installation.

### Timeline

- 2019: README artwork and early documentation frame Evans around easier gRPC inspection and scripting.
- README documents official installation paths via GitHub Releases, Homebrew, Docker, and `go install`.

### Related projects

- The README compares CLI mode to grpc-ecosystem/polyglot and documents compatibility with gRPC reflection and gRPC-Web.
