If you just want to use eno, see the guide. If you want to implement an eno library or otherwise need deeper insight on the language, this is the right resource, read on.


Eno documents must be encoded as UTF-8.

Filename Extension

When saved to disk, eno documents should use the .eno extension.


There are plans to officialy apply to the IANA to get text/eno registered as an offical MIME type for eno documents. If you would like to follow that process or bring in expertise and support you are very welcome to do so in the respective issue on github.


Eno contains only ordered data structures. The order of elements as authored in a document is always retained by parsers.


In eno there is no type differentiation on the language level, there are only textual representations ("strings"), which are always referred to as values.
