PRT (POP Rich Text) is a safe, small and strict rich text serialisation protocol which can be used in server - client communication. The protocol is JSON compatible.

document         ::=   { type_pair, version_pair, dialect_pair, elements_pair }
type_pair        ::=   'type' : 'PRTDocument'
version_pair     ::=   'version' : version_string
version_string   ::=   'unsigned integer.unsigned integer'
dialect_pair     ::=   <optional 'dialect' : string>
elements_pair    ::=   'elements' : elements
elements         ::=   null | text | <sequence of element>
element          ::=   null | text | [ identifier, attributes, elements ]
attributes       ::=   null | { <sequence of attribute_pair> }
attribute_pair   ::=   attribute_name : attribute_value ,
attribute_name   ::=   string
attribute_value  ::=   string
text             ::=   string
identifier       ::=   unsigned integer

The following examples are all in JSON.

1. This example is the smallest possible PRT document:

   {
       "type": "PRTDocument",
       "version": "2.0",
       "elements": null
   }

2. The classic hello-world example:

   {
       "type": "PRTDocument",
       "version": "2.0",
       "dialect": "pop",
       "elements":
       [
           [2, {"id": "source"}, [13, null, ["hello, ", [1, null, "world"], "!"]]]
       ]
   }

   And this can be translated to:

   <code id="source"><pre>hello, <b>world</b>!</pre></code>

• Server side (python)
  • Install: pip install prt
• Client side (javascript) (Reactified implementation)
  • Install: npm install --save prt-client
• GUI binding (javascript) (Draft.js binding)
  • Install: npm install --save prt-draft-js

• 'dialect': 'pop'

• 0x00: 'a'
• 0x01: 'b'
• 0x02: 'code'
• 0x03: 'h1'
• 0x04: 'h2'
• 0x05: 'h3'
• 0x06: 'h4'
• 0x07: 'h5'
