Topic: Python script to generate vertical line numbers for ladder style

I have been bending QElectroTech to do my bidding which right now is ladder style diagrams. I still see a huge number of these style diagrams even on new equipment here in the USA.

Input: Starting number, Increment, Y increment in pixels, Max height in pixels. It will generate code to copy to the clipboard which you can then paste into your folio in QElectroTech.

Re: Python script to generate vertical line numbers for ladder style

Saw file did not show up, here is the code itself you could copy and paste to a new python file:

import tkinter as tk
from tkinter import ttk, scrolledtext

HTML_TEMPLATE = '''        <input y="{y}" x="0" text="&lt;!DOCTYPE HTML PUBLIC &quot;-//W3C//DTD HTML 4.0//EN&quot; &quot;http://www.w3.org/TR/REC-html40/strict.dtd&quot;>&#xa;&lt;html>&lt;head>&lt;meta name=&quot;qrichtext&quot; content=&quot;1&quot; />&lt;style type=&quot;text/css&quot;>&#xa;p, li {{ white-space: pre-wrap; }}&#xa;&lt;/style>&lt;/head>&lt;body style=&quot; font-family:'Liberation Sans'; font-size:9pt; font-weight:400; font-style:normal;&quot;>&#xa;&lt;p style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;>{number}&lt;/p>&lt;/body>&lt;/html>" font="Liberation Sans,9,-1,5,50,0,0,0,0,0,Regular" rotation="0"/>'''

def generate():

    count = max_height // y_step
    inputs = []
    for i in range(count):
        number = start + i * step
        y = i * y_step
        inputs.append(HTML_TEMPLATE.format(number=number, y=y))
