# PDF Engine — Developer Command Reference
---
## ⚠️ Windows — Activate MSVC Before Anything Else
Run this once per terminal session before any `cmake` command:
**Option A — Open a new PowerShell with MSVC loaded**
```powershell
cmd /c '"C:\Program Files (x86)\Microsoft Visual Studio\18\BuildTools\VC\Auxiliary\Build\vcvars64.bat" && powershell'
```
**Option B — Load MSVC into your current PowerShell window**
```powershell
cmd /c '"C:\Program Files (x86)\Microsoft Visual Studio\18\BuildTools\VC\Auxiliary\Build\vcvars64.bat" && set' |
Where-Object { $_ -match '=' } |
ForEach-Object {
$name, $value = $_ -split '=', 2
[System.Environment]::SetEnvironmentVariable($name, $value, 'Process')
}
$env:VCPKG_ROOT = "C:\Users\furqa\vcpkg"
```
If you skip this step, cmake will fail with:
`CMake Error: No CMAKE_CXX_COMPILER could be found.`
---
## One-Time Setup (new machine only)
```powershell
pwsh scripts/bootstrap.ps1
```
```sh
./scripts/bootstrap.sh
```
---
## Component 1 — C++ Engine
### Configure
Run on first setup, after adding `.cpp` files, or after changing `CMakeLists.txt`.
```powershell
cmake --preset windows-debug
```
### Build
Run after changing any C++ source file.
```powershell
cmake --build --preset windows-debug
```
### Test
```powershell
ctest --preset windows-debug
```
Expected output: `100% tests passed`
### Fresh / Clean Rebuild
Use when you see cache errors or strange Ninja errors.
```powershell
cmake --preset windows-debug --fresh
cmake --build --preset windows-debug
```
### Rule R2 Boundary Check
Verifies no raw `FPDF_*` calls exist outside `engine/src/parser/`.
```powershell
pwsh scripts/check_pdfium_boundary.ps1
```
---
## Component 2 — Gateway (FastAPI / Python)
```powershell
cd gateway
python -m pip install -e ".[dev]"
python -m ruff check .
python -m ruff format --check .
python -m pytest
```
---
## Component 3 — Frontend (React / TypeScript)
```powershell
cd frontend
npm install
npm run dev
npm run build
npm run lint
```
---
## Component 4 — WASM (Emscripten)
Activate Emscripten first (one-time install):
```powershell
Get-Content wasm/emsdk.pinned
./emsdk install <version>
./emsdk activate <version>
./emsdk_env.ps1
```
Build and test:
```powershell
cmake --preset wasm
cmake --build --preset wasm
node wasm/hello.test.mjs
```
Expected output:
```
[wasm-smoke] OK — add(2,3)=5, hello_version()=1, cwrap add(40,2)=42
```
Browser test (optional):
```powershell
npx serve .
```
Open `http://localhost:3000/test.html` and check the browser console (F12).
---
## C++ Code Style (clang-format)
Install once (CI is pinned to 22.1.5):
```powershell
pip install clang-format==22.1.5
```
Check formatting:
```powershell
Get-ChildItem -Recurse engine -Include *.cpp,*.cc,*.h,*.hpp |
ForEach-Object { clang-format --dry-run --Werror $_.FullName }
```
Auto-format in place:
```powershell
Get-ChildItem -Recurse engine -Include *.cpp,*.cc,*.h,*.hpp |
ForEach-Object { clang-format -i $_.FullName }
```
---
## Run Everything at Once
Runs all components and prints one pass/fail per component.
```powershell
pwsh scripts/test_phase0.ps1 -Preset windows-debug
pwsh scripts/test_phase0.ps1 -Preset windows-debug -SkipWasm
```
```sh
./scripts/test_phase0.sh
SKIP_WASM=1 ./scripts/test_phase0.sh
```
---
## Automated Convenience Scripts
We have created several PowerShell scripts in the `scripts/` directory to automate setting up the MSVC compiler environments, building, running tests, and starting the FastAPI gateway server. You can run these from the project root:
* **Build C++ Engine & Python Bindings**:
```powershell
powershell -ExecutionPolicy Bypass -File scripts/build_cpp.ps1
```
* **Run C++ Core Unit Tests**:
```powershell
powershell -ExecutionPolicy Bypass -File scripts/test_cpp.ps1
```
* **Run Gateway pytest Integration Tests**:
```powershell
powershell -ExecutionPolicy Bypass -File scripts/test_gateway.ps1
```
* **Start the Local FastAPI Dev Server**:
```powershell
powershell -ExecutionPolicy Bypass -File scripts/start_gateway.ps1
```
