# gh-starred-to-opml

Generates OPML 2.0 files to track the syndication of Releases from your favorite Github repositories. In their whole or by listings.

----


## Introduction

Each repository's Releases page on Github has a [link](https://github.com/user/repository/releases.atom) to an atom file.

This **syndication feeds** allows, among other things :
  - to monitor the appearance of new releases,
  - without having to bother with notifications,
  - to monitor the disappearance of a repository.

Moreover with the recent feature of **[starred repositories lists](https://github.blog/changelog/2021-12-09-lists-are-now-available-as-a-public-beta/)**, you can choose to **follow only some personal categories** of releases.

- The **1st issue** lies in the fact tha **Github's interface does not provide** any feature to **export** these atom file in bulk.

- Github's API does provide an [endpoint](https://docs.github.com/en/rest/activity/starring?apiVersion=2022-11-28#list-repositories-starred-by-a-user) to fetch all the repositories starred by an user, it's easy to generate the atom list from here.

- But, a **2nd issue** is that this **[API does not yet provide](https://github.com/community/community/discussions/8293)** an endpoint to **filter the starred repositories by a List** created by the user.

**gh-starred-to-opml** is a bash script that will fetch these informations for you and generate a file that can be imported in most Feed Reader applications, like [Miniflux](https://github.com/miniflux/v2).


## Requirements

- Run with bash 5.+
- curl (sudo apt install curl)
- [jq](https://github.com/stedolan/jq/) (sudo apt install jq)
- [pup](https://github.com/ericchiang/pup) (go install github.com/ericchiang/pup@latest)


## Usage

```bash
./gh-starred-to-opml.sh -h
Generate an OPML 2.0 file to follow releases of starred repositories on Github
Default to all starred repos of the user, or a specific list with [-l list].

Syntax: ./gh-starred-to-opml.sh [-h] -u user [-l listname] [-d date] [-o filename] [-n filename]
options:
-h              Print this Help
-u string       required: Github username
-l string       optional: Github Stars List (url shortname)
-d string       optional: ISO8601 date to filter out starred before (YYYY-mm-ddTHH:MM:SSZ)
-o string.opml  optional: destination opml filename
-n string.opml  Use a previous file to generate updates,
                it does not require any other option,
                but it uses starred_at dates, not starred in a list.
```

The resulting file can be imported in a Feed Reader.
  - The first `<outline text="">` will provide the category's name.
  - `<dateCreated>` & `<dateModified>` respresent the oldest & most recent dates where repositories in the list where starred. It can help for updates.

## Example

Cropped OPML extract from my Favorites list:

```xml
<?xml version="1.0" encoding="UTF-8"?>
    <opml version="2.0">
        <head>

            </outline>
        </body>
    </opml>
```


## To be done

Some repositories do not offer Releases but will update Tags to signify a milestone.
- See if I can add an option to track tags.
