TagUI-for-Python

To install this Python package for digital process automation (also known as RPA) -

pip install tagui

To use TagUI for Python in Jupyter notebook, Python script or interactive shell -

import tagui as t

To deploy in environments without internet access, join the discussion here -

t.init(); t.url('https://github.com/tebelorg/TagUI-Python/issues/36')

Use Cases

TagUI for Python's simple, expressive and powerful API makes digital process automation fun and easy!

WEB AUTOMATION

t.init()
t.url('https://www.google.com')
t.type('q', 'decentralization[enter]')
t.snap('page', 'results.png')
t.close()

VISUAL AUTOMATION

t.init(visual_automation = True)
t.dclick('outlook_icon.png')
t.click('new_mail.png')
...
t.type('message_box.png', 'message')
t.click('send_button.png')
t.close()

OCR AUTOMATION

t.init(visual_automation = True)
t.echo(t.read('pdf_window.png'))
t.echo(t.read('image_preview.png'))
t.hover('anchor_element.png')
t.echo(t.read(t.mouse_x(), t.mouse_y(), t.mouse_x() + 400, t.mouse_y() + 200))
t.close()

KEYBOARD AUTOMATION

t.init(visual_automation = True, chrome_browser = False)
t.keyboard('[cmd][space]')
t.keyboard('safari[enter]')
t.keyboard('[cmd]t')
t.keyboard('avengers[enter]')
t.wait(2.5)
t.snap('page.png', 'results.png')
t.close()

MOUSE AUTOMATION

t.init(visual_automation = True)
t.type(600, 300, 'open source')
t.click(900, 300)
t.snap('page.bmp', 'results.bmp')
t.hover('button_to_drag.bmp')
t.mouse('down')
t.hover(t.mouse_x() + 300, t.mouse_y())
t.mouse('up')
t.close()

API Reference

Check out sample Python script and RedMart groceries example.

  • For web automation, web element identifier can be XPath selector, CSS selector or the following attributes - id, name, class, title, aria-label, text(), href (in decreasing order of priority). There is automatic waiting for an element to appear before timeout happens, and error is returned that the element cannot be found. To change the default timeout of 10 seconds, use timeout() function.

  • An element identifier can also be a .png or .bmp image snapshot representing the UI element (can be on desktop applications or web browser). x, y coordinates of elements on the screen work as well. Transparency (0% opacity) is supported in .png images, for eg using an image of an UI element with transparent background to enable clicking on an UI element that appears on different backgrounds on different occasions.

  • A further example is an image of the window or frame (PDF viewer, MS Word, textbox etc) with the center content of the image set as transparent. This allows using read() and snap() to perform OCR and save snapshots of application windows, containers, frames, textboxes with varying content. Also for read() and snap(), x1, y1, x2, y2 coordinates pair can be used to define the region of interest on the screen to perform OCR or capture snapshot.

About & Credits

TagUI is the number #1 open-source RPA software with thousands of active users. It was created in 2016-2017 when I left DBS Bank as a test automation engineer, to embark on a one-year sabbatical to Eastern Europe. Most of its code base was written in Novi Sad Serbia. My wife and I also spent a couple of months in Budapest Hungary, as well as Chiang Mai Thailand for visa runs. In 2018, I joined AI Singapore to continue development of TagUI.

Over the past 2 months I took on a daddy role full-time, taking care of my newborn baby girl and wife. In between nannying and caregiving, I decided to use my time pockets to create a Python package for TagUI. I would like to bring RPA into the heart of machine learning - the Python ecosystem. I hope that TagUI for Python and ML frameworks would be a match made in heaven, and that pip install tagui would make lives easier for Python users.

Lastly, at a mere 1000 lines of code, it would make my day to see developers of other languages porting this project over to their favourite programming language. It would be an interesting exercise and should not be difficult, given the ample comments I sprinkled all over this single-file package in tagui.py, and its intuitive architecture.
