action.yml
file automatically from code- feature:
generate
- feature:

octocrab
- feature:
- Actions ToolCache support
- Locating tools in the toolcache
- feature:
toolcache
🚀 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
