Interval Notation

[m3cubed]

Description

Compute engine can't recognize interval notation from mathlive

Steps to Reproduce

Actual Result

Expected Result

Not sure what the proper MathJSON would be but perhaps something like ["Interval", 3, 4]. I'm not sure how to show a closed interval on one side thought.

Interval Notation Parsing: Added support for parsing mathematical interval notation from LaTeX, including half-open intervals.

// Half-open intervals (American notation)
ce.parse('[3, 4)').json;   // → ["Interval", 3, ["Open", 4]]
ce.parse('(3, 4]').json;   // → ["Interval", ["Open", 3], 4]

// Open intervals (ISO/European notation)
ce.parse(']3, 4[').json;   // → ["Interval", ["Open", 3], ["Open", 4]]

// LaTeX bracket commands
ce.parse('\\lbrack 3, 4\\rparen').json;  // → ["Interval", 3, ["Open", 4]]

Contextual Parsing: Lists and tuples are automatically converted to intervals when used in set contexts (Element, Union, Intersection, etc.):

ce.parse('x \\in [0, 1]').json;
// → ["Element", "x", ["Interval", 0, 1]]

ce.parse('[0, 1] \\cup [2, 3]').json;
// → ["Union", ["Interval", 0, 1], ["Interval", 2, 3]]

// Standalone notation remains backward compatible
ce.parse('[0, 1]').json;  // → ["List", 0, 1]
ce.parse('(0, 1)').json;  // → ["Tuple", 0, 1]

compute engine can recognize it but it still has trouble recognizing the mathfield inputs
