Math equation js

Write math equations for the browser in html in a simple format, the script converts it into math ml

I got inspiration from the math typesetting from typst https://typst.app/docs/reference/math/. But as of now there isn't a simple way to write math equations in the browser html.

Mathml features

MathML is divided into two parts:

Presentation MathML: Focuses on how mathematical notation is displayed visually.
Content MathML: Describes the structure and meaning of math expressions in a semantic way.

Attribute	Description	Example
msup	Superscript: like `a^2`	$a^{2}$
msub	Subscript: like `a_2`	$a_{2}$
mfrac	Fraction: like `a/b`	$\frac{a}{b}$
msqrt	Square root: like `sqrt(2)`	$\sqrt{2}$
msubsup	Integral: like `int_a^b(x^2)`	$\int_{a}^{b} x^{2}$
mo	Operator: like `a -> b`	$a \to b$
mi	Identifier: like `x`	$x$
mn	Number: like `2`	$2$
mfenced	Group: like `(a + b)`	$(a + b)$
mspace	Space: like `a b`	$a b$
mstyle	Style: like `bold(a)`	$a$
Matrix	like `[1 2; 3 4]`	$[\begin{matrix} 1 & 2 \\ 3 & 4 \end{matrix}]$
mtable, mtr, mtd	Table: like `(1 2 3; 4 5 6)`	$(\begin{matrix} 1 & 2 & 3 \\ 4 & 5 & 6 \end{matrix})$
Quadratic formula	like `(-b +- sqrt(b^2 - 4ac)) / 2a`	$x = \frac{- b \pm \sqrt{b^{2} - 4 a c}}{2 a}$
Summation	like `sum_(i=1)^infinity 1/i^2`	$\sum_{i = 1}^{\infty} \frac{1}{i^{2}}$
Limits	like `lim_(x->0) sin(x)/x`	$lim_{x \to 0} \frac{\sin (x)}{x}$
Logarithm	like `log_2(8)`	$\log_{2} (8)$
Derivative	like `d(f(x))/dx`	$\frac{d f (x)}{d x}$

Grammar

The grammar is simple, it is similar to asciimath but goal is to cover all the functionality of typst.


    expression := unary_expression ~ (binary_op ~ unary_expression)*
    unary_expression := primary_expression | prefix_expression | postfix_expression
    primary_expression :=  number | identifier | array | function_call | "(" ~ expression ~ ")" 
    array := "[" ~ expression ~ ("," ~ expression)* ~ "]"
    function_call := identifier ~ ("(" ~ (expression ~ ("," ~ c_expression)*)? ~ ")")+ 
    prefix_expression := unary_op ~ primary_expression 
    postfix_expression := primary_expression ~ unary_op 
    binary_op := "+" | "-" | "*" | "/" | "^" | "==" | "!=" | "<" | ">" | "<=" | ">=" | "&&" | "||"
    unary_op := "-" | "!" | "++" | "--"
