Sympy generator from LaTeX expressions.

Project description

# latex2sympy

latex2sympy parses LaTeX math expressions and converts it into the
equivalent SymPy form.

## Installation

[ANTLR]( is used to generate the parser:

$ antlr4 PS.g4 -o gen

## Usage

In Python 2.7:

from process_latex import process_sympy

process_sympy("\\frac{d}{dx} x^{2}")
# => "diff(x**(2), x)"

## Examples

|LaTeX|Image|Generated SymPy|
|`x^{3}`|![](| `x**3`|
|`\frac{d}{dx} |t|x`|![](|`Derivative(x*Abs(t), x)`|
|`\sum_{i = 1}^{n} i`|![](|`Sum(i, (i, 1, n))`|
|`\int_{a}^{b} \frac{dt}{t}`|![](|`Integral(1/t, (t, a, b))`|
|`(2x^3 - x + z)|_{x=3}`|![](|`z + 51`
