Import External Library (QRCodeGenerator)

[Cator]

Hoping to help someone build custom apps in Alibre Script, I’m sharing the process that led me to create this script for generating QR Codes.

When you want to create a project that does not use the libraries present in IronPython of Alibre Script, the procedure to follow is this:

---

1. **Download the `qrcode-6.1.tar.gz` library compatible with Python 2.7:**
Qrcode 6.1

---

2. **Extract the content and copy the folder to:**
`C:\Program Files\Alibre Design 28.0.1.28098\Program\Addons\AlibreScript\PythonLib\site-packages`

---

3. **Start AlibreScript and in an empty script, test the import:**

---

import qrcode

**and press RUN**

We will receive an error ☹. To make an imported library work, it is necessary to specify the path each time.

---

4. **So, at the beginning of each script, we will use:**

  import sys
   sys.path.append("C:\\Program Files\\Alibre Design 28.0.1.28098\\Program\\Addons\\AlibreScript\\PythonLib\\site-packages\\qrcode-6.1")
   import qrcode

At this point, you will still receive an error. `qrcode` has a dependency, a missing library: `six`.

---

5. **Let's repeat the same procedure for the `six` library:**
six-1.16.tar.gz

---

6. **Extract the content and copy the folder to:**
`C:\Program Files\Alibre Design 28.0.1.28098\Program\Addons\AlibreScript\PythonLib\site-packages`

---

7. **Then we will import both libraries and can use them simply:**

 import sys
   sys.path.append("C:\\Program Files\\Alibre Design 28.0.1.28098\\Program\\Addons\\AlibreScript\\PythonLib\\site-packages\\qrcode-6.1")
   sys.path.append("C:\\Program Files\\Alibre Design 28.0.1.28098\\Program\\Addons\\AlibreScript\\PythonLib\\site-packages\\six-1.16.0")
   import os
   import qrcode
   import qrcode.image.svg

With this code, you should be able to use the `qrcode` library in Alibre Script without any issues.

---

import sys
# Add the paths for the qrcode and six libraries to the system path
sys.path.append("C:\Program Files\Alibre Design 28.0.1.28098\Program\Addons\AlibreScript\PythonLib\site-packages\qrcode-6.1")
sys.path.append("C:\Program Files\Alibre Design 28.0.1.28098\Program\Addons\AlibreScript\PythonLib\site-packages\six-1.16.0")

import os
import qrcode
import qrcode.image.svg

# Create a Windows dialog for user interaction
Win = Windows()
ScriptName = 'Export QRCode'

Options = []
# Add an option for the user to input their part number
Options.append(['Design Data', WindowsInputTypes.String, 'Insert your part number'])
# Add an option for the user to choose the file save location
Options.append(['File', WindowsInputTypes.SaveFile, os.path.expanduser("~"), 'File', 'SVG|*.svg', '.svg'])
# Add a label for the user
Options.append(['Label', WindowsInputTypes.Label, 'Export the QR Code in SVG on your Desktop'])
Values = Win.OptionsDialog(ScriptName, Options, 200)
if Values is None:
    sys.exit()

# Data for the QR code
data = Values[0]

# Create the QR Code with an SVG renderer
factory = qrcode.image.svg.SvgPathImage
qr = qrcode.QRCode(
    version=1,
    error_correction=qrcode.constants.ERROR_CORRECT_L,
    box_size=10,
    border=4,
    image_factory=factory,
)

qr.add_data(data)
qr.make(fit=True)

# Generate the QR image
img = qr.make_image()

file_path = Values[1]

# Save the image to an SVG file on the desktop
with open(file_path, "w") as f:
    img.save(f)

print("The QR code has been saved to: {}".format(file_path))

I hope everyone and especially @NateLiquidGravity and @stepalibre, that you can check it out, I'd love to know what you think.
