Lingu is extensible programming language that is operating with domain abstractions and not their implementation details.

This technology is WIP and exploring ideas similar to concept programming and intentional programming.

Check out TodoMVC app implemetation with Lingu here.

Lingu sentences are divided into these categories:

1. Data structure definitions
2. Action sentences
3. Query definitions
4. Translations

Each action sentence is constructed out of words. Each word is either plugin, handler, evaluator, value, query, selector or datatype.

(words, parseState, appState) => ({mutateState: (s) => s, parseState, cursor})

Lingu.handlers.keyUp = (words) => {
  Lingu.domEventHandlers.push({
    selector: words[0],
    handler: (event) => {
      const parseState = {
        event: event
      };
      Lingu.methods.parseActionLine(words.slice(1), parseState);
    },
    event: 'keyup'
  });
};

triggered on first run of the app

triggered when change in data is detected

triggered on element click

triggered on input element blur

triggerred when click happens outside element

triggered on element double click

triggered on keyUp in input

triggered on escape key in input

triggered on enter key in input

(words, parseState, appState) => ({value: [], parseState, cursor})

returns value from selected elements

evaluates to true if selected elements have empty value, otherwise evaluates to false

evaluates to true if query returns items that equal value, otherwise evaluates to false

evaluates to true if query returns any items, otherwise evaluates to false

evalutes to true if value is false, otherwise evaluates to false

converts query result to value

You can extend language by adding your own custom plugins, evaluators and handlers to Lingu.plugins, Lingu.evaluators and Lingu.handlers.
