Strict Content MathML Editor

This editor helps to create Strict Content MathML 3.0 expressions.

Features

• Support of custom symbols, e.g. type Umax and get the single symbol U_max instead of the product Umax in the formula editor
• Support of SI prefixes and units
• Support of piecewise-defined expressions
• Automatic detection of integers, real numbers and rational numbers

Result

This Strict Content MathML Editor is based on Guppy which is licensed under the MIT License.

Custom Symbols

You can define custom mathematical/physical symbols for later use in the formula.

Example: By defining a custom symbol U_max, you can type Umax in the formula editor and get the single symbol U_max instead of the product Umax. In this case, the resulting MathML is <ci>Umax</ci>.

Definition

You may use an underscore to separate the main symbol from a subscript.

Usage

To use a custom symbol, just enter its (case-sensitive) name in the editor.

If a symbol has a subscript, enter its name without underscore in the editor.

Installation

See README.md.

Usage

See README.md.
