Usage
Init Gists via Git
Opengist allows you to create new snippets via Git over HTTP.
Simply init a new Git repository where your file(s) is/are located:
shell
git init
git add .
git commit -m "My cool snippet"
Then add this Opengist special remote URL and push your changes:
shell
git remote add origin http://localhost:6157/init
git push -u origin master
Log in with your Opengist account credentials, and your snippet will be created at the specified URL:
shell
Username for 'http://localhost:6157': thomas
Password for 'http://thomas@localhost:6157':

remote:
remote: If you want to keep working with your gist, you could set the remote URL via:
remote: git remote set-url origin http://localhost:6157/thomas/6051e930f140429f9a2f3bb1fa101066
remote:
To http://localhost:6157/init
* [new branch] master -> master
Embed a Gist to your webpage
To embed a Gist to your webpage, you can add a script tag with the URL of your gist followed by .js to your HTML page:
html
<script src="http://opengist.url/user/gist-url.js"></script>
<!-- Dark mode: -->
<script src="http://opengist.url/user/gist-url.js?dark"></script>
Retrieve Gist as JSON
To retrieve a Gist as JSON, you can add .json to the end of the URL of your gist:
shell
curl http://opengist.url/thomas/my-gist.json | jq '.'
It returns a JSON object with the following structure similar to this one:
json
