About Ktr0731 Evans

From the project's README at github.com/ktr0731/evans. Lightly cleaned for readability; for the full source see the upstream repo.

[](https://github.com/ktr0731/evans/actions) [](https://codecov.io/gh/ktr0731/evans) [](https://pkg.go.dev/github.com/ktr0731/evans) Motivation Evans has been created to use easier than other existing gRPC clients. If you want to keep your product quality, you must use CI with gRPC testing, should not do use manual testing. Evans will complete your other use cases just like: Manually gRPC API inspection To automate some tasks by scripting

The above use cases are corresponding to Evans's two modes, REPL mode, and CLI mode. REPL mode

REPL mode is the solution for first use case. You can use it without thinking like the package name, service name, RPC name, command usage, and so on because REPL mode has powerful completion! CLI mode

CLI mode is a stateless mode just like grpc-ecosystem/polyglot. It sends one request per one command as its name suggests. So it is based on UNIX philosophy.
