# STP2GLB Desktop GUI Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Build a green-distribution Windows desktop GUI that lets external users run single-file and batch directory STEP-to-GLB conversions through the existing `STP2GLB.exe` without using the command line.
**Architecture:** Add a Tauri desktop shell under a new `desktop/` workspace. The frontend handles form input, mode switching, validation, and log/result presentation. The Tauri Rust backend locates sibling executables, builds CLI arguments, executes `STP2GLB.exe`, streams logs back to the UI, and validates output existence before reporting success.
**Tech Stack:** Tauri, Vite, TypeScript, React, Vitest, Rust, Cargo tests

### Task 1: Scaffold the desktop workspace
**Files:**
- Create: `desktop/package.json`
- Create: `desktop/tsconfig.json`
- Create: `desktop/vite.config.ts`
- Create: `desktop/index.html`
- Create: `desktop/src/main.tsx`
- Create: `desktop/src/App.tsx`
- Create: `desktop/src/styles.css`
- Create: `desktop/src-tauri/Cargo.toml`
- Create: `desktop/src-tauri/tauri.conf.json`
- Create: `desktop/src-tauri/build.rs`
- Create: `desktop/src-tauri/src/main.rs`
- Modify: `.gitignore`
- [ ] **Step 1: Write the failing workspace smoke check**
Create `desktop/package.json` scripts first, then run the install command before files are complete to confirm the workspace does not build yet.
```json
{
"name": "stp2glb-desktop",
"private": true,
"version": "0.1.0",
"type": "module",
"scripts": {
"dev": "vite",
"build": "tsc && vite build",
"test": "vitest run",
"tauri:dev": "tauri dev",
"tauri:build": "tauri build"
}
}
```
- [ ] **Step 2: Run the workspace smoke check to verify it fails**
Run: `npm install`
Expected: install succeeds or partially succeeds, but `npm run build` fails with missing source/config files.
- [ ] **Step 3: Add the minimal desktop scaffold**
Add the minimal Vite + Tauri shell.
```tsx
// desktop/src/main.tsx
import React from "react";
import ReactDOM from "react-dom/client";
import App from "./App";
import "./styles.css";
ReactDOM.createRoot(document.getElementById("root")!).render(
<React.StrictMode>
<App />
</React.StrictMode>,
);
```
```tsx
// desktop/src/App.tsx
export default function App() {
return (
<main className="app-shell">
<header className="hero">
<h1>STP2GLB Converter</h1>
<p>Desktop GUI bootstrap complete.</p>
</header>
</main>
);
}
```
```rust
// desktop/src-tauri/src/main.rs
#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]
fn main() {
tauri::Builder::default()
.run(tauri::generate_context!())
.expect("failed to run tauri application");
}
```
- [ ] **Step 4: Run the build checks to verify the scaffold passes**
Run: `npm run build`
Expected: Vite build passes.
Run: `cargo test`
Workdir: `desktop/src-tauri`
Expected: `running 0 tests` and PASS.
- [ ] **Step 5: Commit**
```bash
git add .gitignore desktop
git commit -m "feat: scaffold desktop gui workspace"
```
### Task 2: Define form types, presets, and frontend validation
**Files:**

- Create: `desktop/src/lib/presets.ts`
- Create: `desktop/src/lib/validation.ts`
- Create: `desktop/src/components/__tests__/validation.test.ts`
- Create: `desktop/src/components/__tests__/preset-mapping.test.ts`
- Modify: `desktop/package.json`
- [ ] **Step 1: Write the failing preset and validation tests**
```ts
// desktop/src/components/__tests__/preset-mapping.test.ts
import { describe, expect, it } from "vitest";
import { getPresetValues } from "../../lib/presets";
describe("getPresetValues", () => {
it("returns standard precision defaults", () => {
expect(getPresetValues("standard")).toEqual({
linearDeflection: 0.1,
angularDeflection: 0.5,
});
});
});
```
```ts
// desktop/src/components/__tests__/validation.test.ts
import { describe, expect, it } from "vitest";
import { validateForm } from "../../lib/validation";
describe("validateForm", () => {
it("rejects missing input path", () => {
const result = validateForm({
mode: "single",
inputPath: "",
outputPath: "D:/output/model.glb",
compressionMode: "replace",
});
expect(result.valid).toBe(false);
expect(result.errors.inputPath).toContain("请选择输入文件");
});
});
```
- [ ] **Step 2: Run tests to verify they fail**
Run: `npm run test`
Expected: FAIL with module-not-found or exported-function-not-found errors.
- [ ] **Step 3: Add minimal types, presets, and validation**
```ts
// desktop/src/types.ts
export type ConversionMode = "single" | "batch";
export type PrecisionPreset = "low" | "standard" | "high" | "custom";
export type CompressionMode = "replace" | "separate";
export interface FormState {
mode: ConversionMode;
inputPath: string;
outputPath: string;
compressionMode: CompressionMode;
compressedOutputPath?: string;
precisionPreset?: PrecisionPreset;
linearDeflection?: number;
angularDeflection?: number;
}
```
```ts
// desktop/src/lib/presets.ts
import type { PrecisionPreset } from "../types";
const presetMap = {
low: { linearDeflection: 0.5, angularDeflection: 0.8 },
standard: { linearDeflection: 0.1, angularDeflection: 0.5 },
high: { linearDeflection: 0.01, angularDeflection: 0.1 },
custom: { linearDeflection: 0.1, angularDeflection: 0.5 },
} satisfies Record<PrecisionPreset, { linearDeflection: number; angularDeflection: number }>;
export function getPresetValues(preset: PrecisionPreset) {
return presetMap[preset];
}
```
```ts
// desktop/src/lib/validation.ts
import type { FormState } from "../types";
export function validateForm(form: FormState) {
const errors: Record<string, string> = {};
if (!form.inputPath.trim()) {
errors.inputPath = "请选择输入文件或输入目录";
}
if (!form.outputPath.trim()) {
errors.outputPath = "请选择输出位置";
}
if (form.mode === "single" && !form.outputPath.toLowerCase().endsWith(".glb")) {
errors.outputPath = "单文件模式下,输出文件必须为 .glb";
}
if (form.compressionMode === "separate" && !form.compressedOutputPath?.trim()) {
errors.compressedOutputPath = "请选择压缩输出位置";
}
return {
valid: Object.keys(errors).length === 0,
errors,
};
}
```
- [ ] **Step 4: Run tests to verify they pass**
Run: `npm run test`
Expected: PASS for the two new test files.
- [ ] **Step 5: Commit**
```bash
git add desktop/package.json desktop/src

```ts
// desktop/src/components/__tests__/app-shell.test.tsx
import { render, screen } from "@testing-library/react";
import { describe, expect, it } from "vitest";
import App from "../../App";
describe("App shell", () => {
it("renders the four primary sections", () => {
render(<App />);
expect(screen.getByText("转换来源")).toBeInTheDocument();
expect(screen.getByText("输出位置")).toBeInTheDocument();
expect(screen.getByText("转换参数")).toBeInTheDocument();
expect(screen.getByText("执行状态")).toBeInTheDocument();
});
});
```
- [ ] **Step 2: Run tests to verify they fail**
Run: `npm run test`
Expected: FAIL because the section titles are not rendered yet.
- [ ] **Step 3: Implement the minimal professional shell**
```tsx
// desktop/src/App.tsx
import { useMemo, useState } from "react";
import type { FormState } from "./types";
const initialForm: FormState = {
mode: "single",
inputPath: "",

};
export default function App() {
const [form, setForm] = useState<FormState>(initialForm);
const title = useMemo(
() => (form.mode === "single" ? "单文件转换" : "批量目录转换"),
[form.mode],
);
return (
<main className="app-shell">
<header className="hero">
<div>

```rust
// desktop/src-tauri/src/tests.rs
#[cfg(test)]
mod tests {
use crate::command_builder::{build_args, ConversionRequest, Mode};
#[test]
fn builds_single_file_args() {
let request = ConversionRequest {
mode: Mode::Single,
input_path: "D:/input/a.stp".into(),
output_path: "D:/output/a.glb".into(),
linear_deflection: 0.1,
angular_deflection: 0.5,
relative_deflection: false,
solid_only: false,
debug: false,

}
}
```
- [ ] **Step 2: Run tests to verify they fail**
Run: `cargo test`
Workdir: `desktop/src-tauri`
Expected: FAIL because `command_builder` and request types do not exist.
- [ ] **Step 3: Add minimal request types and CLI builder**
```rust

```rust
#[test]
fn output_verification_requires_expected_file() {
use crate::runner::verify_single_output;
use std::path::Path;
assert!(!verify_single_output(Path::new("D:/missing/output.glb")));
}
```
- [ ] **Step 2: Run tests to verify they fail**
Run: `cargo test`
Workdir: `desktop/src-tauri`
Expected: FAIL with missing runner function.
- [ ] **Step 3: Implement minimal execution path**
```rust
// desktop/src-tauri/src/runner.rs
use std::path::Path;
use std::process::{Command, Stdio};
pub fn verify_single_output(path: &Path) -> bool {
path.exists() && path.is_file()
}
pub fn run_process(executable: &Path, args: &[String]) -> std::io::Result<std::process::Child> {
Command::new(executable)
.args(args)
.stdout(Stdio::piped())
.stderr(Stdio::piped())
.spawn()
}
```
```rust
// desktop/src-tauri/src/main.rs
#[tauri::command]
fn count_step_files(input_dir: String) -> Result<usize, String> {
crate::fs_ops::count_step_files(input_dir).map_err(|err| err.to_string())
}
#[tauri::command]
fn run_conversion(request: crate::types::ConversionRequest) -> Result<(), String> {
let executable = crate::executable::find_converter().map_err(|err| err.to_string())?;
let args = crate::command_builder::build_args(&request);
let child = crate::runner::run_process(&executable, &args).map_err(|err| err.to_string())?;

- Modify: `desktop/src/components/RunPanel.tsx`
- Modify: `desktop/src/components/LogPanel.tsx`
- Test: `desktop/src/components/__tests__/app-shell.test.tsx`
- [ ] **Step 1: Extend the failing UI test for execution feedback**
```ts
it("disables the run button when the form is invalid", () => {
render(<App />);
expect(screen.getByRole("button", { name: "开始转换" })).toBeDisabled();
});
```
- [ ] **Step 2: Run tests to verify they fail**

Expected: FAIL because the button state and command wiring are not implemented.
- [ ] **Step 3: Add minimal invoke wiring and app state**
```ts
// desktop/src/lib/command.ts
import { invoke } from "@tauri-apps/api/core";
import type { FormState } from "../types";
export function runConversion(form: FormState) {
return invoke("run_conversion", {
request: {
mode: form.mode === "single" ? "single" : "batch",
inputPath: form.inputPath,
outputPath: form.outputPath,
linearDeflection: form.linearDeflection ?? 0.1,
angularDeflection: form.angularDeflection ?? 0.5,
relativeDeflection: false,
solidOnly: false,
debug: false,

setStatus("error");
} finally {
setIsRunning(false);
}
}
```
- [ ] **Step 4: Run tests and build to verify the integration passes**
Run: `npm run test`
Expected: PASS.
Run: `npm run build`
Expected: PASS.
- [ ] **Step 5: Commit**

git commit -m "feat: wire desktop gui to conversion backend"
```
### Task 7: Finish green-distribution packaging and operator documentation
**Files:**
- Create: `docs/desktop-gui-release.md`
- Modify: `README.md`
- Modify: `desktop/src-tauri/tauri.conf.json`
- [ ] **Step 1: Write the failing release checklist as documentation**
Create `docs/desktop-gui-release.md` with a checklist that references files and commands that do not exist yet.
```md
# Desktop GUI Release
- Build frontend
- Build Tauri app
- Copy STP2GLB.exe next to the GUI executable
- Verify single conversion on a clean machine
```
- [ ] **Step 2: Run the release build to verify the packaging is incomplete**
Run: `npm run tauri:build`
Expected: build fails or produces an app bundle without the converter binary copied into the expected release location.
- [ ] **Step 3: Add the minimal packaging configuration and docs**
```json
// desktop/src-tauri/tauri.conf.json
{
"productName": "STP2GLB Converter",
"version": "0.1.0",
"build": {
"frontendDist": "../dist"
},
"bundle": {
"active": true,
"targets": "nsis",
"externalBin": [
"../bin/STP2GLB.exe",
"../bin/gltfpack.exe"
]
}
}
```
```md
<!-- docs/desktop-gui-release.md -->
# Desktop GUI Release
## Build
1. Run `npm install`
2. Run `npm run build`
3. Run `npm run tauri:build`
## Green distribution directory
- Place `STP2GLB.exe` next to the desktop executable or in the configured sidecar path.
- Place `gltfpack.exe` in the same distribution directory when compression is enabled.
- Verify one single-file conversion and one batch conversion before shipment.
```
- [ ] **Step 4: Run the final release build checks**
Run: `npm run build`
Expected: PASS.
Run: `npm run tauri:build`
Expected: PASS and generate a distributable desktop build.
- [ ] **Step 5: Commit**
```bash
git add README.md docs desktop/src-tauri/tauri.conf.json
git commit -m "docs: add desktop gui release flow"
```

## Self-Review
### Spec coverage
- Single-file conversion: Covered by Tasks 2, 4, 5, 6.
- Batch directory conversion: Covered by Tasks 2, 5, 6.
- Professional single-window UI: Covered by Task 3.
- Basic + advanced options: Covered by Tasks 2, 3, 6.
- Live logs and execution status: Covered by Tasks 5 and 6.
- Green-distribution release path: Covered by Task 7.
- Output verification and understandable failures: Covered by Tasks 5 and 6.
### Placeholder scan
- No `TODO`, `TBD`, or “implement later” placeholders remain in tasks.
- Each task lists exact files.
- Each code step includes concrete code snippets.
- Each verification step includes commands and expected outcomes.
### Type consistency
- UI uses `FormState`, `PrecisionPreset`, and `CompressionMode` consistently across validation and command invocation.
- Backend uses `ConversionRequest` and `Mode` consistently across command building and execution.
- The request fields in `command.ts` match the backend `camelCase` names defined in `types.rs`.
