This Fork

The primary goal has been to get Deepnest buildable again, which has been achieved.

Prerequisites

• Node 14/16/18/20: Node.js. You can use the Node Version Manager (nvm):
  • nvm-windows to download Node and change versions.
• Python 3.7.9 You can use the Python Version Manager (pyenv):
  • pyenv-win to download and change versions.
• Visual Studio with Desktop Development with C++ extension
  • Install VS2022 from https://visualstudio.microsoft.com/vs/features/cplusplus/
  • or, as an administrator via npm install --global windows-build-tools (older VS version)

For ubuntu (or when you're not sure how to build) look at the build workflow:

https://github.com/deepnest-io/Deepnest/blob/master/.github/workflows/build.yml#L28

Possible Problems

• On Windows 10 1905 or newer, you might need to disable the built-in Python launcher via
  • Start > "Manage App Execution Aliases" and turning off the "App Installer" aliases for Python"
• close-and-open all command shells and your IDE to activate the latest setup

Building

git clone https://github.com/deepnest-io/Deepnest
cd Deepnest
npm install
npm run build
npm run start

Rebuild

# If you change the electron-related files (web files, javascript), a build with 
npm run build

# If you change the the Minkowski files (the `.cc` or `.h` files):
npm run build-all

Running

• npm run start

Clean builds

npm run clean  && npm run build

# full clean, incl. `node_modules`
npm run clean-all && npm install && npm run build

Create a Distribution

npm run dist

# During development, you can combine `clean-all, build-all and dist` via:
npm run dist-all

The resulting files will be located in .\deepnest-<version>-win32-x64.

Create a zip file of this folder for a simple distribution.

Debugging

If the environment variable "deepnest_debug" has a value of "1", Deepnest will open the browser dev tools (debugger/inspector).
