# Phase 4 Plan 01: Script Generator (Install) Summary
|
||||
|
||||
**One-liner:** Jinja2-based install.ps1 generator with WOW64 guard, UAC elevation, pnputil two-step, and duplex mapping
|
||||
|
||||
## What Was Built
|
||||
|
||||
A TDD-developed module `imptune/generators/script_generator.py` with a single public function `render_install()` that renders the `install.ps1.j2` Jinja2 template into a complete, production-ready PowerShell printer install script.
|
||||
|
||||
### render_install() function
|
||||
|
||||
- Takes plain string arguments (no ORM dependency) for easy unit testing
|
||||
- Translates `duplex_mode` via `_duplex_map` before passing to template
|
||||
- Converts Python booleans to lowercase strings (`"true"`/`"false"`) for PowerShell `$true`/`$false` rendering
|
||||
|
||||
### install.ps1.j2 template structure (in order)
|
||||
|
||||
1. Header comment with printer name and required Intune install command
|
||||
2. WOW64 guard (`$env:PROCESSOR_ARCHITECTURE` + `SysNative` relaunch) — FIRST executable block
|
||||
3. SYSTEM vs admin detection (`[WindowsIdentity]::GetCurrent()`, `IsSystem`, `IsInRole(Administrator)`) + UAC self-elevation via `Start-Process -Verb Runas`
|
||||
4. pnputil two-step: `/add-driver` to stage INF, then `Add-PrinterDriver` to register
|
||||
5. Idempotent port creation: `Get-PrinterPort` check before `Add-PrinterPort`
|
||||
6. Idempotent printer creation: `Get-Printer` check before `Add-Printer`
|
||||
7. `Set-PrintConfiguration` with translated duplex, color, paper size, collate
|
||||
|
||||
## TDD Execution
|
||||
|
||||
### RED Phase (commit b4f2c64)
|
||||
|
||||
7 tests written in `tests/test_script_generator.py` covering SCRPT-01, SCRPT-04, SCRPT-05. All failed with `ModuleNotFoundError` (confirmed RED).
|
||||
|
||||
### GREEN Phase (commit 8193e9d)
|
||||
|
||||
- `imptune/generators/script_generator.py` created
|
||||
- `imptune/templates/scripts/install.ps1.j2` created
|
||||
|
||||
One auto-fix required during GREEN: template comment contained `"pnputil.exe"` before the WOW64 `PROCESSOR_ARCHITECTURE` check text, causing the ordering assertion in `test_render_install_wow64_guard` to fail. Fixed by removing `.exe` from the comment text. Not a logic error — purely a textual ordering issue in the rendered output.
|
||||
|
||||
All 7 new tests pass. Full suite: 68/68 passing.

|

| Hash | Type | Description |

|------|------|-------------|
|
||||

|
||||
## Deviations from Plan
|
||||
|
||||
### Auto-fixed Issues
|
||||
|
||||
**1. [Rule 1 - Bug] Template comment contained 'pnputil.exe' before WOW64 guard text**
|
||||
- **Found during:** GREEN phase test run
|
||||
- **Issue:** Comment in the WOW64 guard block header said "pnputil.exe is 64-bit only", so the string "pnputil.exe" appeared in the rendered output before "PROCESSOR_ARCHITECTURE", breaking the ordering assertion in `test_render_install_wow64_guard`
|
||||
- **Fix:** Changed "pnputil.exe is 64-bit only" to "pnputil is 64-bit only" in the template comment
|
||||
- **Files modified:** `imptune/templates/scripts/install.ps1.j2`
|
||||
- **Commit:** 8193e9d (included in same GREEN commit)
