To generate flow charts from simple pseudo-codes

txtoflow (Translate To Flowchart)

The Python library can be used to generate flowcharts from pseudo-code.

Installation

You may need to install the following graphviz tools and libraries first

On Ubuntu ...

sudo apt-get install graphviz libgraphviz-dev pkg-config

Then

pip install txtoflow

Usage

from txtoflow import txtoflow

txtoflow.generate(
    '''
    if (A) {
        B;
    } else {
        C;
        D;
        while (E) {
            F;
        }
        G;
    }
    H;
    '''
)

Will generate an image named flowchart.jpg in current dir that looks like below

All the conditions and states can be arbitrary strings too

from txtoflow import txtoflow

txtoflow.generate(
    '''
    First Node;
    if (A != 10) {
        B;
    } else if (Just a String) {
        Another String;
    } else {
        Else Body;
        More Statements;
        while (While also works) {
            While Body;
        }
        Link back;
    }
    Final Node;
    '''
)

Will still generate image like below
