Repo Structure

This repo contains the QGIS plugin for Speckle 2.0. It is written in python and uses our fantastic Python SDK. The Speckle Server is providing all the web-facing functionality and can be found here.

Try it out!! Although we're still in early development stages, we encourage you to try out the latest stable release. Just follow the instructions on this file, and head to the Releases page to download the necessary files and dependencies.

What can it do?

Currently, the plugin allows to send data from a single layer to a Speckle server using one of the accounts configured on your computer. It will extract all the features of that layer along side their properties and, when possible, geometry too. The following geometry types are supported for now:

  • Point
  • Multipoint
  • Polyline (LineString)
  • MultiLineString
  • Polygon
  • MultiPolygon
  • More to come!!

Installation

QGIS Marketplace

You can find Speckle QGIS in the QGIS Plugins -> Manage and install plugins menu item.

The plugin is currently published as experimental, so make sure you go to Settings and activate the Show also experimental plugins checkbox.

Then go to the All tab and search for Speckle. You should see the plugin appear in the list:

alt

Manual install

You'll need to place the speckle_qgis folder into your plugins folder. To find this folder, go to the "Settings" menu and select "User Profiles" > "Open Active Profile Folder".

active project folder

Inside this folder, navigate into the python folder then the plugins folder. Once inside the plugins folder, drop your speckle_qgis folder into it.

Speckle Dependencies

You no longer need to take care of installing the dependencies! This will be done automatically if the package is not found.

Launching the Plugin

You should now launch QGIS and you should see SpeckleQGIS in your installed plugins. Click the blue brick in the toolbar to open the plugin.

Developing

Setup

Setup is a bit cumbersome for now. The following is adapted from this tutorial

Qt Creator

To edit the UI of the plugin, you'll want to install Qt creator. You can find the free installers on this page in the "Qt Creator" tab. On Windows, you'll be prompted to create an account during the installation process.

qt creator install

Python Qt Bindings

For Windows, the bindings are already included in the QGIS installation.

For Mac, you can install PyQt using homebrew.

brew install pyqt

Install pb_tool

pb_tool allows you to compile resource files from into something python will understand.

For this plugin we only have one file to convert:

  • resources.qrc -> resources.py

To install pb_tool, just run:

pip install pb_tool

or

YOUR_PYTHON_EXECUTABLE -m pip install pb_tool

For convenience, the pre-compiled resources.py file so you don't really have to do anything here.

Dev Environment

For a better development experience in your editor, we recommend creating a virtual environment. In the venv, you'll just need to install specklepy. You will also need to copy over the qgis module into the {venv}/Lib/site-packages. You can find the qgis module in your QGIS install directory:

  • Windows: C:\Program Files\QGIS 3.20.1\apps\qgis\python
  • MacOS: /Applications/QGIS.app/Contents/Resources/python

qgis dependency for venv

QGIS Plugins

Though it is not required, we recommend installing these plugins from the QGIS Plugin Manager:

  • Plugin Reloader (allows you to reload the plugin without restarting QGIS)
  • Remote Debugger (enables interactive debugging)
  • First Aid (shows errors before crashing QGIS, sometimes)

Debugging

Visual Studio Code

First, you'll need to uncomment these 2 lines in the __init__.py file:

    # from speckle.utils import enable_remote_debugging
    # enable_remote_debugging()

This will automatically setup ptvsd if it's not already installed, and start listening to port 5678.

In VS Code, you can use the built in python debugger. You'll need to create a debug configuration by creating a launch.json file.

Create Debug Config

Select the "Python" -> "Remote Attach" option. Your launch.json should look like this:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python: Remote Attach",
      "type": "python",
      "request": "attach",
      "port": 5678,
      "host": "localhost",
      "pathMappings": [
        {
          "localRoot": "${workspaceFolder}",
          "remoteRoot": "${workspaceFolder}"
        }
      ]
    }
  ]
}

To start debugging, you'll need to first launch QGIS. Once it's running, run your debug Python: Remote Attach configuration.

That's all there is to it! Now any breakpoints you create should be hit.

successful debugging in vs code

If you want to have the debugger wait for you to connect using VSCode, you can uncomment this line in the speckle/utils.py file:

  #ptvsd.wait_for_attach()

Enjoy!
