About

Themed SVG Studio edits version 1 themed-SVG manifests alongside source SVGs. Its scope is semantic theme data: tokens, presets, palette overrides, and explicit selector bindings. Geometry editing is intentionally out of scope.

The reusable D library contains the editor model, manifest types, diagnostics, undo/redo, and an isolated JSON/JSONL subprocess boundary for @dev-centr/themed-svg. Protocol version 1 reserves inspect, validate, transform, sanitize, and export.

Build

dub test -c unittest
dub build -c cli
dub build -c gui-headless
dub build -c gui # native Windows host

All product configurations select TGC. DUI is the application layer over Dew. The registry dependency chain uses DUI 0.1.4, Dew 0.1.7, vello-d 0.1.4 where the GPU configuration needs it, and TGC 0.1.1.

Install the versioned transformation companion before running previews or exports:

npm install --global @dev-centr/themed-svg@0.2.1

CLI

.\themed-svg-studio-cli.exe smoke
.\themed-svg-studio-cli.exe validate --svg diagram.svg --manifest diagram.theme.json

The external bridge command defaults to themed-svg-stdio from @dev-centr/themed-svg 0.2.1. Use --bridge when testing another executable path. The app also honors THEMED_SVG_STDIO; on Windows it checks the normal per-user npm executable directory when the command is not already on PATH.

Product surfaces

The GUI exposes token, preset, and binding inspectors; source, fixed, light, dark, standalone-adaptive, and host previews; About, Help, redacted debug dump, and honest update status. v0.1.0 does not claim automatic update application.
