# 25 — Rewrite notes and idiosyncrasies
|
||
|
||
The new ICCery is **not** Tauri. Keep the product name, cone artwork, unmanaged-print semantics, and Argyll process boundary.
|
||
|
||
## Four different meanings of `-d`
|
||
|
||
| Tool | `-d` means |
|
||
|------|------------|
|
||
| `targen` | colourant combination (`2` RGB, `4` CMYK) |
|
||
| `printtarg` | custom **label** string (fork) |
|
||
| `iccgamut` | surface **density** (number, e.g. `10`) |
|
||
| `colprof` | output viewing condition |
|
||
|
||
Passing the wrong `-d` is the #1 class of silent misconfiguration (#112).
|
||
|
||
## Flags that look similar
|
||
|
||
- printtarg `-r` = no randomize / raster layout; targen `-r` = full-spread algorithm
|
||
- printtarg `-R seed` vs targen `-R` algorithm
|
||
- applycal `-u` = **unapply** curves, **not** JSON
|
||
- chartread `-Y l` (letter L) = LEDs; original ticket proposed `-L`
|
||
|
||
## JSON prefixes are inconsistent (fork)
|
||
|
||
| Tool | `-u` stdout |
|
||
|------|-------------|
|
||
| `chartread` | **`ROW_COLORS_JSON: `** + compact JSON |
|
||
| `printtarg` | pretty-printed **bare** JSON manifest |
|
||
| `profcheck` | one compact **bare** JSON line |
|
||
| `targen` / `colprof` | compact JSON (fork) — ICCery currently **does not** pass `-u` |
|
||
| `instlist` | pretty JSON, no `-u` needed |
|
||
|
||
Only chartread lines are intercepted by ProcessManager. Manifest/profcheck JSON arrives as `process:stdout` and must be parsed from the accumulator.
|
||
|
||
## Windows musts
|
||
|
||
- `CREATE_NO_WINDOW` (`0x08000000`) on every Argyll spawn
|
||
- `.exe` candidate first (`resolve_binary`)
|
||
- `.icm` default extension
|
||
- GDI `SetICMMode(ICM_OFF)` + `DMICMMETHOD_NONE`
|
||
- Cache full DEVMODE bytes from DocumentProperties (#36) — applying fields onto a fresh DEVMODE drops driver extras
|
||
- Hide CUPS checkbox (`#cupsOptionsGroup`)
|
||
- PeekNamedPipe fork + `ARGYLL_NOT_INTERACTIVE=1`
|
||
- TIFF→PNG in host, not in the webview
|
||
|
||
## macOS musts
|
||
|
||
- Preferences = **NSPrintPanel on the AppKit main thread**, never System Settings URL, never cupsctl web UI (#188 comments 1–5)
|
||
- `PMPrinterCreateFromPrinterID(CUPS id)` then `display_name` → `NSPrinter::printerWithName`
|
||
- Private SPI via `dlsym`: **2-argument** `(PMPrintSession, *const CFString) -> i32`. Passing integer `1` as a lock flag **SIGSEGV**. Try Lock, then Mode, then NoLock. Modes: `AP_ApplicationColorMatching` then `ApplicationColorMatching` only
|
||
- Dual keys `AP_ColorMatchingMode` and dotted `AP.ColorMatchingMode`
|
||
- Mirror into `NSPrintInfo.printSettings` dictionary (PDEs read this)
|
||
- Pre-select Canon `CNIJIntent2=4`, Epson `EPIJ_CMat=3` (or `EPIJ_CCor=0`), Gutenprint `StpColorCorrection=Uncorrected`
|
||
- `lp` always includes both AP_* options + captured cups_options + bypass if missing
|
||
- Cancel = `Ok(None)`, not an error
|
||
- Dark WKWebView: `drawsBackground=NO`, under-page colour, window hidden until paint
|
||
- `minimumSystemVersion` 12.0
|
||
- Ad-hoc sign Argyll Mach-O sidecars on Apple Silicon (#165)
|
||
- TargetPrint companion uses **different** ColorSync keys (`APCustomColorMatching`). Do not mix the two dictionaries.
|
||
|
||
## Linux musts
|
||
|
||
- `lp` not `lpr`
|
||
- Default `-o raw`; fallback `ColorModel=Gray` + `cm-calibration` if `#chkPpdFallback`
|
||
- Enumerate `lpstat -e/-p/-d` + `lpoptions -p -l` + `/etc/cups/ppd/{name}.ppd`
|
||
|
||
## Frontend musts
|
||
|
||
- No WebGL until Stage 5 visible; pause rAF on leave; survive context lost
|
||
- `iccgamut -d 10` density
|
||
- Average snapshots delete canonical `.ti3`
|
||
- Open dialogs for import; save dialogs only when saving
|
||
- No `innerHTML` for user-supplied preset/dataset names
|
||
- Atomic history writes
|
||
- Deterministic printtarg `-R 1`
|
||
- Honour patch count `-f`
|
||
|
||
## Suggested characterisation tests (from tickets)
|
||
|
||
Lock these before rewriting UI:
|
||
|
||
1. `build_*_args` golden vectors (already in Rust unit tests — port them)
|
||
2. `classifyChartreadLine` 39 cases
|
||
3. `parseGamutFile` multi-`BEGIN_DATA`, comments, OOB vertices
|
||
4. `parseProfcheckReport` JSON + legacy + empty→warning
|
||
5. Color bypass detector: Canon/Epson/Gutenprint samples
|
||
6. `filter_cups_options_string` drops `com.apple.*`, keeps `EPIJ_CMat`
|
||
7. `build_lp_args` always emits both AP_* keys
|
||
8. Threshold validation `good < warning`
|
||
9. `snapshot_ti3` 1-based and removes canonical
|
||
10. DEVMODE round-trip size
|
||
|
||
## Host command list (complete)
|
||
|
||
From `lib.rs` `generate_handler!` — a rewrite should provide equivalents with the **same argument names** (Tauri command arguments are `camelCase` at the IPC boundary, Rust fields `snake_case` inside structs).

## Licence / AGPL
|
||
|
||
GUI: proprietary EULA (`LICENCE.md`). Argyll sidecars: AGPLv3, subprocess-only. Third-party: Three.js r128 MIT, OrbitControls, CSS2DRenderer, quickhull. Rewrite may swap the renderer but must not link Argyll.
