What is WireMan?

WireMan is a terminal-based gRPC client with a user-friendly interface. It reads .proto files from a config file and keeps a history of requests. WireMan is an ideal choice for developers testing gRPC endpoints directly from the terminal.

Getting Started with WireMan

This guide will walk you through the steps to set up and run WireMan.

Prerequisites

Rust: [Minimum required Rust version is 1.70] (Installation Guide)

Installation

Install with cargo

cargo install wireman

Install manually

Clone the repository:

git clone https://github.com/preiter93/wireman.git

Build in release mode:
```
cd wireman
cargo build --release
```

Copy the binary to your PATH, e.g.:

cp target/release/wireman /usr/local/bin

Alternatively, you can create an alias to the binary in your .bashrc or .zshrc file:

echo "alias wireman='CURRENT_DIRECTORY/target/release/wireman'" >> ~/.zshrc

Configuration

Set the WIREMAN_CONFIG_DIR environment variable to specify the directory where your configuration file will be located:
```
export WIREMAN_CONFIG_DIR=~/.config/wireman
```
Create the directory specified in WIREMAN_CONFIG_DIR:
```
mkdir -p ~/.config/wireman
```

Create a wireman.toml file in the specified directory. Here's an example configuration:

includes = [
    "$HOME/your-project"
]

files = [
    "a-proto-file-in-your-project.proto"
]

[server]
default_address = "http://localhost:50051"

[history]
directory = "$WIREMAN_CONFIG_DIR/history"  # Optional. Defaults to $WIREMAN_CONFIG_DIR/history.
autosave = true                            # Optional. Autosaves history on request. Defaults to true.
disabled = false                           # Optional. History is enabled by default.

[logging]
directory = "$WIREMAN_CONFIG_DIR"          # Optional. Defaults to $WIREMAN_CONFIG_DIR.
level = "Debug"                            # Optional. Defaults to Debug.

# [ui]
# skin = "$WIREMAN_CONFIG_DIR/skins/dracula.toml"  # Optional. Set a UI theme.

Replace with the appropriate values for your project.

Optionally, you can now verify the setup configuration
```
wireman check 
```

Usage

After adding the protos in the config, start wireman.
Basic key mappings are displayed in the footer of each page. For extended help, press ? and close with ? or Esc. If you want to close the app entirely, type Ctrl+c.
The first page of Wireman will list your grpc services and their methods. You can navigate with up/down or j/k, select with Enter or unselect with Esc, then click Tab.
The second page is the message screen. Edit your request message, you can format it with Ctrl+f. Then click tab. The navigation of the editor is vim-inspired: use h, j, k, l for motion, go into insert mode with i, and escape insert mode with Esc. For more details, refer to edtui.
The third page is the config screen where you can edit the address or metadata. Wireman allows for using bash scripts to get your tokens. Place the name of your script in the bearer token field, which must be in your PATH, between $(). For example, if you have a bash script named getToken.sh that prints the Bearer token ey..., you would use $(getToken.sh) (the script output should not include the word 'Bearer', as it is automatically added). Additional headers can be added with Ctrl+a and deleted with Ctrl+d. Go to the request page with Shift+Tab or click tab twice.
Now you can make the request by clicking Enter. You can save it with Ctrl+s. Saved requests are stored in spots 1 to 5. Switch to a spot by clicking the respective number. You can restore the default request with Ctrl+d, which deletes the history. You can also cancel a request with Esc. To copy the response: Navigate to the response by clicking down, enter visual mode by pressing v, select everything and copy the selected text by pressing y. Or follow step 6.
If you want to get the current request as a gRPCurl command, click Ctrl+y on the request tab, and it's copied to your clipboard.

Troubleshooting

Wireman logs important information and errors to assist in troubleshooting. By default, logs are stored in $WIREMAN_CONFIG_DIR/wireman.log.Make sure to check this log file if you encounter any unexpected behavior or errors while using the application.

If you are unable to resolve the issue on your own or need further assistance, please don't hesitate to open an issue.

Custom Skins

Wireman allows users to customize the appearance of the UI by adding custom skins. To do this, simply specify the desired skin file in the wireman.toml file config:

[ui]
skin = "path_to_file/custom_skin.toml"

For a collection of pre-made themes, check out the Wireman themes repository.

Demo

Server Reflection

Wireman also supports server reflection of gRPC servers. To activate reflection mode, press Ctrl + r on the selection tab, enter the host along with optional authentication headers, and then press Enter. To switch back from reflection mode to file mode press Ctrl + r again.
