Dependencies

Build/Dev

• GNU Make
• docker

Libraries

required

• pandoc (e.g. apt-get install pandoc for Debian-based, or pacman -S pandoc for Arch Linux)

(optional) For headless browser functionality (uses selenium):

• pyenv
• libxext6
• libxt6
• geckodriver and firefox

Compatibility

• python3.10

• NOTE: working on expanding compatibility...

• NOTE: still a work in progress for sure.

Helpful tips

...definitely recommend using a virtual environment, e.g. via docker or conda.

Install

From PyPi:

python3 -m pip install desmos2python

Examples

DesmosLatexParser API Example:

import desmos2python as d2p

# `file` contains a JSON-formatted list of latex equations
# loads the example defined in 'resources/latex_json/ex.json'
dlp = d2p.DesmosLatexParser(file='ex.json')

# `pycode_string` contains the ready-to-eval Desmos model namespace 
print(dlp.pycode_string)

# Instantiate a model namespace
# The attributes define any formulas, parameters from the specified Desmos graph
dmn = dlp.DesmosModelNS()

# for example, evaluate the function E(x) over the domain x=(1, 2, 3)
result = dmn.E([1, 2, 3])
print(result)

# see ./tests for more examples!
