An alternative grammar for parsing mathematical expressions for LaTeXML, implemented in Marpa::R2
perl Makefile.PL ; make
make test # Tests LaTeXML::MathSyntax
make test_classic # Tests LaTeXML::MathGrammar
Aims to also provide:
- A comprehensive test suite for parsing mathematical expressions into content MathML
- An automated test harness for developing math grammars for LaTeXML
- Convenient domain-specific languages for writing down tests (e.g. a write-efficient serialization for Content MathML)
- Gradually formalising all of DLMF's ~10,000 equations.
- Intending to formalize ~1,000 or more formulas from arXiv.org
- Each item in the test suite consists of a
<TeX formula, Content MathML tree>tuple. - The TeX can be any input written in a real-world mathematical document.
- The Content MathML tree must be written in the strict CMML syntax, complying with existing content dictionaries.
- The CMML tree must avoid large semantic rewrites of the input expression.
Example: In the case of an ellipssis (...) the annotation should ideally preserve the ellipsis explicitly
via a special underspecified symbol, such as :underspecified:ellipsis.
Full formalization is not only difficult, but also not always possible, for ellided content.
The rule of thumb should always be to consider whether a math grammar should realistically be expected to perform
the analysis necessary for the rewrite.
