Introduction

pyecharts-javascripthon helps translate Python functions into javascript ones. It uses javascripthon and dukpy to blend Python codes into javascript runtime. It supports python 2.7, 3.4, 3.5 and 3.6. It works on Linux, MacOS and Windows platforms.

Sample python function:

def renderItem(params, api):
    values = [api.value(0), api.value(1)]
    coord = api.coord(values)
    size = api.size([1, 1], values)
    return {
        "type": 'sector',
        "shape": {
            "cx": params['coordSys']['cx'],
            "startAngle": coord[3] - size[1] / 2
            }
        }

Compiled python functions:

function renderItem(params, api) {
    var coord, size, values;
    values = [api.value(0), api.value(1)];
    coord = api.coord(values);
    size = api.size([1, 1], values);
    return {"type": "sector", "shape": {"cx": params["coordSys"]["cx"], "startAngle": (coord[3] - (size[1] / 2))}};
}

From Python 2.7 to Python 3.4

Internet access is required because it uses javascripthon api as a free service. Down the line, community sponsorship will be required to cover the running cost of the service.

Because the service is still under development, the default api key and api host are subjected to change. When it does happen please declare these environment variables to continue:

for unix alike systems:

export SCRIPTHON_HOST=new_ip_address_or_domain_name
export SCRIPTION_API_TOKEN=new_api_key

for windows systems:

set SCRIPTHON_HOST=new_ip_address_or_domain_name
set SCRIPTION_API_TOKEN=new_api_key

Python 3.5 - 3.6

No internet access is required.

Usage

1. Only Python 3.5+ code can be transcompiled. If you use python 2.7 or 3.4, you are obliged to use generic Python codes so that python 2.7 and 3.4 interpreter do not complain.

  1. For browsers DOM object, please include some of these statements so as to ‘blind’ python interpreter:
from pyecharts_javascripthon.dom.objects import window    # for window object
from pyecharts_javascripthon.dom.objects import Document  # for Document object
from pyecharts_javascripthon.dom.objects import Date      # for Date object
