Jevko for hackers

For do-it-yourself-oriented tinkerers, hackers, or minimalists plain Jevko is ready to be used to define custom formats for all kinds of applications that deal with tree-structured information.

Experimental software

Use Jevko today

For solution-oriented users, Jevko formats like those shown above are in development and available to experiment with via the Jevko CLI or the Jevko Interface for Visual Studio Code.

Jevko CLI and Jevko for VS Code

You can try out the formats you see above today with the experimental Jevko Command Line Interface or the Jevko Interface for Visual Studio Code. These can convert Jevko into JSON, HTML, or various XML-based formats. This allows for easy integration with existing applications.

Jevko formats give you the full power of the target format via JSON or XML literals and data-model compatibility. On top of that you get features such as here documents (via the backwards-compatible Jevko syntax extension), extremely lean comments, ability to disable (“comment out”) an entire Jevko subtree by prefixing it with “-”, autotrimmed unquoted strings, or quoted multiline strings.

All this in a very simple human-friendly syntax.

Syntax highlighting

Experimental Jevko syntax highlighting extensions for Visual Studio Code are available for the following formats/file types:

• Data interchange: .jevkodata
• Configuration: .jevkocfg (same extension as .jevkodata for now)
• Markup: .jevkoml
• Generic: .jevko

There are also experimental Jevko syntax highlighting definitions for other environments:

• Generic: .jevko – KDE KatePart Syntax Highlight System, CodeMirror6
