A VS Code extension that adds a custom editor for .gds (GDSII layout)
files: open one and it's parsed and rendered in a WebGL2 canvas, with
support for loading a KLayout .lyp file to drive layer colors.
Features
Parses and renders GDSII layouts directly in a VS Code webview.
Optional KLayout .lyp file loading for custom layer colors.
Handles SREF/AREF (including array references), rotation, mirroring, and
magnification via gdstk's flattening.
Per-layer visibility toggles and an infill (fill pattern) toggle.
Usage
Open any .gds file in VS Code and it opens in the GDS Lens viewer:
Pan / zoom — drag to pan, scroll to zoom.
Layers — toggle individual layer visibility from the panel.
Infill — toggle the hatched layer fill on or off from the panel.
Reset View — refit the layout to the window from the panel.
Load KLayout .lyp File — apply custom layer colors from a .lyp file.
GDSLens: Toggle Debug Tools — command palette entry that shows/hides
the render stats readout and debug log.
