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. ### Sources - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
