## GitHub Actions Go (aka golang) Toolkit

The GitHub Actions Go ToolKit provides a set of packages to make creating actions easier.

This toolkit is a pure go port of the official [@actions/toolkit](https://github.com/actions/toolkit)

## Creating an Action with the Toolkit

:question: [Choosing an action type](https://github.com/actions/toolkit/docs/action-types.md)

Outlines the differences and why you would want to create a JavaScript or a container based action.




:curly_loop: [Versioning](https://github.com/actions/toolkit/docs/action-versioning.md)

Actions are downloaded and run from the GitHub graph of repos. This contains guidance for versioning actions and safe releases.



:warning: [Problem Matchers](https://github.com/actions/toolkit/docs/problem-matchers.md)

Problem Matchers are a way to scan the output of actions for a specified regex pattern and surface that information prominently in the UI.



Hello World Go Action

Illustrates how to create a simple hello world javascript action.

```go
import "github.com/actions-go/toolkit/core"

func main() {
whoToGreet := core.GetInput("who-to-greet")
fmt.Println("Hello", whoToGreet)
}
```

Hello World JavaScript Action

Illustrates how to create a simple hello world javascript action.

```javascript
...
const nameToGreet = core.getInput('who-to-greet');
console.log(`Hello ${nameToGreet}!`);
...
```

JavaScript Action Walkthrough



Walkthrough and template for creating a JavaScript Action with tests, linting, workflow, publishing, and versioning.

```javascript
async function run() {
try {
const ms = core.getInput('milliseconds');
console.log(`Waiting ${ms} milliseconds ...`)
...
```
```javascript
PASS ./index.test.js
✓ throws invalid number
✓ wait 500 ms
✓ test runs

Test Suites: 1 passed, 1 total
Tests: 3 passed, 3 total
```

TypeScript Action Walkthrough

Walkthrough creating a TypeScript Action with compilation, tests, linting, workflow, publishing, and versioning.

```javascript
import * as core from '@actions/core';

async function run() {
try {
const ms = core.getInput('milliseconds');
console.log(`Waiting ${ms} milliseconds ...`)
...
```
```javascript
PASS ./index.test.js
✓ throws invalid number
✓ wait 500 ms
✓ test runs

Test Suites: 1 passed, 1 total
Tests: 3 passed, 3 total
```



Docker Action Walkthrough

Create an action that is delivered as a container and run with docker.

```docker
FROM alpine:3.10
COPY LICENSE README.md /
COPY entrypoint.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
```

Docker Action Walkthrough with Octokit

Create an action that is delivered as a container which uses the toolkit. This example uses the GitHub context to construct an Octokit client.

```docker
FROM node:slim
COPY . .
RUN npm install --production
ENTRYPOINT ["node", "/lib/main.js"]
```
```javascript
const myInput = core.getInput('myInput');
core.debug(`Hello ${myInput} from inside a container`);

const context = github.context;
console.log(`We can even get context data, like the repo: ${context.repo.repo}`)
```
