# TODO to Issue Action
This action will convert your `# TODO` comments to GitHub issues when a new commit is pushed.
The new issue will contain a link to the line in the file containing the TODO, together with a code snippet. The action performs a `GET` request to retrieve GitHub's [`languages.yml` file](https://raw.githubusercontent.com/github/linguist/master/lib/linguist/languages.yml) file to apply highlighting to the snippet.
It will also close an issue when a `# TODO` is removed in a pushed commit. A comment will be posted
with the ref of the commit that it was closed by.
The `# TODO` comment is commonly used in Python, but this can be customised to whatever you want.
## Usage
Create a workflow file in your .github/workflows directory as follows:
### workflow.yaml
name: "Workflow"
on: ["push"]
jobs:
build:
runs-on: "ubuntu-latest"
steps:
- uses: "actions/checkout@master"
- name: "TODO to Issue"
uses: "alstr/todo-to-issue-action@master"
with:
REPO: ${{ github.repository }}
BEFORE: ${{ github.event.before }}
SHA: ${{ github.sha }}
TOKEN: ${{ secrets.GITHUB_TOKEN }}
LABEL: "# TODO"
COMMENT_MARKER: "#"
id: "todo"
### Inputs
| Input | Description |
|----------|-------------|
| `REPO` | The path to the repository where the action will be used, e.g. 'alstr/my-repo' (automatically set) |
| `BEFORE` | The SHA of the last pushed commit (automatically set) |
| `SHA` | The SHA of the latest commit (automatically set) |
| `TOKEN` | The GitHub access token to allow us to retrieve, create and update issues (automatically set) |
| `LABEL` | The label that will be used to identify TODO comments (by default this is `# TODO` for Python) |
| `COMMENT_MARKER` | The marker used to signify a line comment in your code (by default this is `#` for Python) |
## Examples
### Adding TODOs
def hello_world():
# TODO Come up with a more imaginative greeting
print('Hello world!')
This will create an issue called "Come up with a more imaginative greeting".
**The action expects a space to follow the `TODO` label.**
Should the title be longer than 50 characters, it will be truncated for the issue title.
The full title will be included in the issue body and a `todo` label will be attached to the issue.
### Multiline TODOs
def hello_world():
# TODO Come up with a more imaginative greeting
# Everyone uses hello world and it's boring.
print('Hello world!')
You can create a multiline todo by continuing below the initial TODO declaration with a comment.
The extra line(s) will be posted in the body of the issue.
The `COMMENT_MARKER` input must be set to the correct syntax (e.g. `#` for Python).
### Removing TODOs
def hello_world():
print('Hello world!')
Removing the `# TODO` comment will close the issue on push.
### Updating TODOs
def hello_world():
# TODO Come up with a more imaginative greeting, like "Greetings world!"
print('Hello world!')
Should you change the `# TODO` text, this will currently create a new issue, so bear that in mind.
This may be updated in future.
