# source2rosetta-gen

Render a published [source2rosetta](../../README.md) gamedata release into whatever format your framework
reads. `source2rosetta` does the hard part — deriving CS2 / Dota 2 gamedata from the stripped engine and
validating it on a live server — and publishes two JSON files per game. `source2rosetta-gen` turns those into
CounterStrikeSharp, Metamod/SourceMod, ModSharp, Swiftly, Plugify, or a typed C# SDK, locally, in a second.

It's deliberately tiny: it links only `source2rosetta-core` (serde + the format emitters) — **no** ELF reader,
no disassembler, no ptrace. So a consumer who "just wants the files" downloads one release + this small binary
and generates exactly what they need, instead of every format being pre-baked into the release.

## Get it

Grab the prebuilt `source2rosetta-gen` from the release page, or build it from source:

```sh
cargo build --release -p source2rosetta-core
# -> target/release/source2rosetta-gen
```

(The `gen` binary lives in the `source2rosetta-core` crate, so a plain `cargo build --release` at the repo root
does **not** build it — use `-p source2rosetta-core` or `--workspace`.)

## Use it

Download the two artifacts for your game from the release page:

- `gamedata-<game>.json` — the derived gamedata (function signatures + vtable offsets), tiered by confidence.
- `netvars-<game>.json` — the typed schema (every class's field offsets + runtime types).

Then point `gen` at whichever you need and pick a `--format`. Output goes to `--out`, or stdout if omitted.

```sh
# CounterStrikeSharp combined gamedata (the default)
source2rosetta-gen --from gamedata-cs2.json --format cssharp   --out gamedata.json

# Metamod / SourceMod gamedata VDF (one .games.txt)
source2rosetta-gen --from gamedata-cs2.json --format metamod   --out csgo.games.txt

# Swiftly / ModSharp / Plugify gamedata
source2rosetta-gen --from gamedata-cs2.json --format swiftly   --out gamedata.json

# Typed C# SDK from the schema — one `static class` per engine class, `const` field offsets + types
source2rosetta-gen --netvars netvars-cs2.json --format cs-sdk  --out Schema.cs

# Flat netvar offset map (class -> field -> offset)
source2rosetta-gen --netvars netvars-cs2.json --format netvars --out netvars.json
```

## Formats

| `--format` | needs | output |
|---|---|---|
| `cssharp` *(default)* | `--from` | CounterStrikeSharp combined gamedata (a commented, sectioned file) |
| `metamod` | `--from` | Metamod:Source / SourceMod gamedata VDF (`.games.txt`) |
| `modsharp` | `--from` | ModSharp gamedata JSON |
| `swiftly` | `--from` | Swiftly gamedata JSON |
| `plugify` | `--from` | Plugify gamedata JSON |
| `model` | `--from` | the canonical model, re-serialized (format-neutral) |
| `cs-sdk` | `--netvars` | typed C# SDK — `static class` per schema class, `const int` field offsets tagged with their type |
| `netvars` | `--netvars` | flat schema map, `{ class: { field: offset } }` |

## Confidence tier

The gamedata formats (the `--from` ones) take a `--tier`, cumulative and defaulting to `high_confidence`:

| `--tier` | includes |
|---|---|
| `core` | only the guaranteed, first-class entries |
| `high_confidence` *(default)* | `core` + the promoted (verified-name) entries |
| `experimental` | the above + every graded name guess (each has a resolvable locator, but an **unverified** name) |

```sh
# only the rock-solid set:
source2rosetta-gen --from gamedata-cs2.json --format cssharp --tier core --out gamedata.json
```

The schema formats (`cs-sdk`, `netvars`) ignore `--tier`.
