# forgejo-todo-checker
Checks your source files for TODO and FIXME comments, where they don't have an open issue number.

A ForgeJo Action.
(Inspired by https://woodpecker-ci.org/plugins/TODO-Checker)
## Comments Format
This Action only pays attention to comments in a particular format. e.g:
```
// TODO: (#19) This is the comment
// FIXME (#29) This is the other comment
# TODO (#19) This is the comment
# FIXME: (#29) This is the other comment
```
These are all considered valid comments. Pick the format that fits your language or file best.
Comments are found by matching them against this regular expression: `(#|//)\s*(TODO|FIXME)`
i.e.: be a comment by starting with either '#' or '//', then the word `TODO` or `FIXME` in all caps.
Once we have a line with such a comment we look for the Issue Number with: `\(#?(?P<ISSUE_NUMBER>\d+)\)`
i.e.: a number in `()`, with or without a leading `#` (inside the braces).
The `ISSUE_NUMBER` must correspond to an **OPEN** Issue in the repo that the Action is running against.
If the issue has been closed or can't be found then the comment is marked as an error and the Check with fail.
## Example Use as a ForgeJo Action Step
```yaml
jobs:
tests:
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Check TODOs
2024-09-20 21:51:01 +01:00
uses: https://git.kemitix.net/kemitix/forgejo-todo-checker@v1.0.0
2024-09-20 17:15:16 +01:00
```
The output will be similar to the following if there are any errors:
```
Forgejo TODO Checker!
Repo: kemitix/my-projext
Prefix: (#|//)\s*(TODO|FIXME)
Issues: ( |)(\(|\(#)(?P<ISSUE_NUMBER>\d+)(\))
- Invalid: src/main.rs#38:
// TODO: implement this cool feature and get rich!
- Closed : (19) README.md#12:
// TODO: (#19) This is the comment
Error: Invalid or closed TODO/FIXMEs found
```
The first error is because there is no issue number associated with the TODO comment.
The second error is because the issue has already been closed.
