IAF Editor Toolkit

With gratitude to Milijan Đokić

This extension is a tribute to Milijan Đokić, the creator of the IAF programming language and one of the pioneers of programming in Yugoslavia and later Serbia. I began my programming journey with IAF and learned a great deal from him. Thank you, Milijan, for the knowledge, patience, and inspiration that have stayed with me throughout my career.

Local usage

Open this folder in VS Code and press F5 to start an Extension Development Host.

To install locally as a VSIX:

npm install -g @vscode/vsce
cd iaf-vscode-extension
vsce package
code --install-extension .\iaf-language-support-0.1.1.vsix

To regenerate help metadata after changing files in IAFHelp:

npm run generate-help-index

IAF Help

The original IAF HTML documentation is included with this extension, so full help pages are available immediately after installation.

To use another copy, run IAF: Select Help Folder from the Command Palette and select an IAFHelp directory. The selected path is saved in your global VS Code settings. The extension checks this path first, then the current workspace and its parent directory, and finally the bundled documentation.

Privacy

The extension works locally. It does not upload source code or IAF Help content.

License
