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>π</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>π</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>π</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)

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.
