🚀 Usage

Here is a simple example of how to use the library:

use ghactions::prelude::*;

#[derive(Actions)]
struct MyAction {}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialise the Action
    let action = MyAction::init()?;

    group!("Main Workflow");

    // Do something...

    Ok(())
}

Advance Usage

Another feature of ghactions is the ability to automatically parse inputs and outputs from the action.

use ghactions::prelude::*;

#[derive(Actions, Debug, Clone)]
#[action(
    // Action Name
    name = "My Action",
    // Action Description
    description = "My Action Description",
)]
struct MyAction {
    /// My Input
    #[input(
        // Change the name of the input from `my_mode` to `mode`
        name = "mode",
        // Input Description
        description = "My Input Description",
        // Default Value
        default = "default"
    )]
    my_mode: String,

    // Automatical type conversion
    #[input(
        // Input Description
        description = "My Input Description",
        default = "42",
    )]
    my_int: i32,

    // Multiple Inputs
    #[input(
        // Input Description
        description = "My Second Input Description",
        // Automatically split the input by `,`
        split = ",",
    )]
    mutiple: Vec<String>,

    // Output called `version`
    #[output(
        // Output Description
        description = "My Output Description",
    )]
    version: String,
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialise the Action
    let action = MyAction::init()?;

    group!("Main Workflow");
    info!("Action :: {:?}", action);

    info!("My Input Mode :: `{}`", action.my_mode);
    info!("My Multiple Input :: `{:?}`", action.mutiple);
    info!("My Output Version :: `{}`", action.version);

    groupend!();

    // Using the toolcache feature
    group!("ToolCache");
    
    // Load the ToolCache from the `examples/toolcache` folder
    let toolcache = ToolCache::from("examples/toolcache");
    // Find the Node.js 18.4.0 tool
    let tool = toolcache.find("node", "18.4.0").await?;
    info!("Tool :: {:?}", tool);

    groupend!();

    // There are 3 ways to set the output
    group!("Set Outputs");

    // Using the dynamically name Action method
    action.set_version("1.0.0");
    // Using the `set_output` method
    MyAction::set_output("version", "1.0.0")?;
    // Or the Macro `setoutput!` directly
    setoutput!("version", "1.0.0");

    groupend!();

    Ok(())
}

Generating the `action.yml` file

The generate feature will allow you to generate the action.yml file from the code.

use ghactions::prelude::*;

#[derive(Actions, Debug, Clone)]
#[action(
    // Action Name
    name = "My Action",
    // Action Location (use `generate` feature to generate action.yml file)
    path = "./action.yml",
    // Set the Actions Dockerfile image
    // `ghactions` will check the Dockerfile exists
    image = "./examples/advanced/Dockerfile",
)]
struct MyAction {
    /// My Input
    #[input(
        // Input Description
        description = "My Input Description",
        // Default Value
        default = "default"
    )]
    my_input: String,

    #[output(
        // Output Description
        description = "My Output Description",
    )]
    my_output: String,
}

At build time, the action.yml file will be generated with the following content:

name: My Action
inputs:
  my_input:
    description: My Input Description
    default: default
outputs:
  my_output:
    description: My Output Description
runs:
  using: "docker"
  image: "Dockerfile"

Using Octocrab

Enabling the octocrab feature will allow you to use the Octocrab library.

use ghactions::prelude::*;

#[derive(Actions, Debug, Clone)]
struct MyAction {}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let action = MyAction::init()?;

    group!("Octocrab");
    // Automatically setup Octocrab with the GitHub Instance and Token
    let octocrab = action.octocrab()?;

    // ... Do something...

    Ok(())
}

Using Template (cargo-generate)

You can use the cargo-generate tool to create a new GitHub Action project with the library.

cargo generate --git https://github.com/42ByteLabs/ghactions
