Is it YAML?

About

"Is it YAML?" is a Django application for checking whether text is YAML ("a human friendly data serialization standard for all programming languages"), or not. Users type and/or copy and paste text and clicks the "Submit" button above. If valid YAML has been entered, the input is presented in canonical form. If not, the application presents an error message.

YAML is just a text format for exchanging data. It exists for cases where XML is too much overhead. I like YAML. I find it more robust in practice than XML (where one missing angle bracket could corrupt a whole file), yet easier to type by hand.

I conjured up "Is it YAML?" while writing a specification for YPath - a language for addressing parts of a YAML document, as XPath does for XML. To do a proper job of things, I had to write YAML example files. However, I sometimes needed to check if the example files are good and proper. "Is it YAML?" gave me a test bed where I can copy-and-paste my examples, and see if they really are YAML.

Installation and Dependencies

Apart from Django, the app depends on PyYAML, a Python parser for YAML. You can get the application from PyPI through the command:

pip install isityaml

Once installed, just add "isityaml" to your INSTALLED_APPS list in settings.py, and add the desired URL in one of the urls.py files.

The HTML template file used to generate HTML has been redesigned to work with the Mezzanine CMS. The redesign removed any explicit references to particular stylesheets found with earlier versions. Feel free to customise: the app is released under a 3 clause BSD license. See LICENSE.txt for more information. If you wish to do any changes, pop over to the GitHub repository for the app.
