A Python driver for Contextual19 markup language

Project description

Read here about Contextual19

Contextual19 Python Interpreter

This module provides you 2 classes to work with Ctx19.


This is just regular parser that takes rules in object representation.


To initialize this class, just call it and take there rules in object representation:

from ctx19 import Contextual19Parser
data = [
		"if": ...,
		"then": ...
parser = Contextual19Parser(data)

Data you passed will be stored in


  • apply(sentence: list) -> list
    This method apply rules, stored in to the sentence you passed.
    sentence is the list of dictionaries which represents tokens with their properties. It can look like this:

     		"tense": "past",
     		"gender": "neutral",
     		"some_other_stuff": "other_value"
     		"tense": "future",
     		"voice": "active",
     		"another_property": "another_value"

    If some property will be missing while rule applying then it will be skipped.

  • save(filepath: str) -> void
    This method will simply save the rules stored in into file you passed as filepath.

  • applyToSentence(rule: dict, sentence: list) -> list This method will apply the given rule to every token in the sentence if possible.

Private methods

There's also some methods that should not be used in your code, but they are widely used in Contextual19Parser.apply method and they can be useful in some cases.

  • applyRule(rule: dict, token: dict) -> dict
    Apply assignments from some rule to the given token. This won't check if the given rule is really appliable to the token in this context. Resulting token will be returned.
  • ruleIsAppliable(rule: dict, sentence: list, token: int) -> bool
    Check if the given rule is appliable to the tokenth token in the sentence. It'll check the context.
  • applyIfPossible(rule: dict, sentence: list, token: int) -> list
    It will apply some rule to the token if it's appliable in this context. Resulting sentence will be returned.
  • applyRulesTo(rules: list, sentence: list, token: int) -> list
    Apply each rule in the given list to the token-th token in the sentence if they're appliable.


This is the children of ctx19.Contextual19Parser with the changed initialization method.


To initialize this parser just pass path to file with rules as the filepath parameter:

from ctx19 import Contextual19FileParser
parser = Contextual19FileParser("path/to/file.ctx19")

Since this is the Contextual19Parser children, it'll inherit all the parent methods, but one new private was added.

Private methods

  • parseFile(void) -> void
    This will parse Contextual19 syntax from the file saved in self.file. You can change the file and call this method again.

Reading other object notation formats

From 1.2 version JSON and YAML parsers was moved in order to make ctx19 independent from other packages, but you can still do it yourself. Here's the example:

import json
from ctx19 import Contextual19Parser
ctx = Contextual19Parser(json.load("path/to/file.json"))
