WireMan
What WireMan is
WireMan is a terminal-based gRPC client for developers testing gRPC endpoints on Linux. It reads .proto files named in a configuration file and supports unary, server-side streaming, client-side streaming, and bidirectional streaming methods. For servers that provide reflection, WireMan can use gRPC server reflection, with optional authentication headers. Requests can include authentication and metadata headers, including bearer tokens supplied by a shell script. The client keeps request history and autosaves it by default, and a current request can be copied as a grpcurl command. The interface offers vim-style navigation, and users can open fields in the system editor. Custom UI skins are supported, with premade themes in a separate repository. WireMan can also be used inside Neovim through the wireman.nvim floating-terminal integration. The project is free and open source under the MIT license. The README lists installation through Cargo, Homebrew, X-CMD, downloaded binaries, or building from source, and sets Rust 1.70 as the minimum required version. The releases page shows v0.3.8 as the latest release. Users seeking assistance are directed to open a GitHub issue.

Getting started
- Open the WireMan GitHub repository.
- Choose an installation route: Cargo, Homebrew, X-CMD, a downloaded binary, or build from source.
