NAME

MathML::itex2MML - Convert itex to MathML

SYNOPSIS

 use MathML::itex2MML;

 $text    = 'This is an inline equation: $\sin(\pi/2)=1$.';

 # convert embedded itex equations to MathML:
 $converted = itex_html_filter($text);  # This is an inline equation: <math xmlns='http://www.w3.org/1998/Math/MathML' display='inline'><semantics><mrow><mi>sin</mi><mo stretchy="false">(</mo><mi>&pi;</mi><mo stretchy="false">/</mo><mn>2</mn><mo stretchy="false">)</mo><mo>=</mo><mn>1</mn></mrow><annotation encoding='application/x-tex'>\sin(\pi/2)=1</annotation></semantics></math>.

 # just the equations:
 $converted = itex_filter($text);  # <math xmlns='http://www.w3.org/1998/Math/MathML' display='inline'><semantics><mrow><mi>sin</mi><mo stretchy="false">(</mo><mi>&pi;</mi><mo stretchy="false">/</mo><mn>2</mn><mo stretchy="false">)</mo><mo>=</mo><mn>1</mn></mrow><annotation encoding='application/x-tex'>\sin(\pi/2)=1</annotation></semantics></math>

 $text    = '\sin(\pi/2)=1';

 # inline equation (without the $'s)
 $converted = itex_inline_filter($text);  # <math xmlns='http://www.w3.org/1998/Math/MathML' display='inline'><semantics><mrow><mi>sin</mi><mo stretchy="false">(</mo><mi>&pi;</mi><mo stretchy="false">/</mo><mn>2</mn><mo stretchy="false">)</mo><mo>=</mo><mn>1</mn></mrow><annotation encoding='application/x-tex'>\sin(\pi/2)=1</annotation></semantics></math>

 # block equation (without the $$'s)
 $converted = itex_block_filter($text);  # <math xmlns='http://www.w3.org/1998/Math/MathML' display='block'><semantics><mrow><mi>sin</mi><mo stretchy="false">(</mo><mi>&pi;</mi><mo stretchy="false">/</mo><mn>2</mn><mo stretchy="false">)</mo><mo>=</mo><mn>1</mn></mrow><annotation encoding='application/x-tex'>\sin(\pi/2)=1</annotation></semantics></math>

DESCRIPTION

MathML::itex2MML converts itex (a dialect of LaTeX) equations into MathML. Inline equations are demarcated by $..$ or \(...\). Display equations are demarcated by $$...$$ or \[...\]. The syntax supported is described here.

It is strongly suggested that you run the output through MathML::Entities, to convert named entities into either numeric character references or UTF-8 characters, if you intend putting the result on the Web.

MathML::itex2MML is based on the commandline converter, itex2MML.

FUNCTIONS

The following functions are exported by default.

  • itex2MML_html_filter

    Take a text string, with embedded itex equations, and convert all the equations to MathML, passing through the rest of the text.

  • itex2MML_filter

    Take a text string, with embedded itex equations, and convert all the equations to MathML, dropping the rest of the text.

  • itex2MML_inline_filter

    Convert a single equation (without the enclosing $'s) to inline MathML.

  • itex2MML_block_filter

    Convert a single equation (without the enclosing $$'s) to block-display MathML.
