# sow-tools

Shared NWN build tooling for Shadows Over Westgate.

This repository owns the Go-based `sow-toolkit` binary used by the separate module and assets repositories.

## Build

Build the development binary into `tools/sow-toolkit`:

```bash
./build-tool.sh
```

Or run directly with Go:

```bash
GOCACHE="$PWD/.cache/go-build" go run ./cmd/nwn-tool --help
```

## Repository Layout

```text
cmd/nwn-tool/      CLI entrypoint
internal/app/      command wiring and console UX
internal/erf/      ERF/MOD/HAK reading and writing
internal/gff/      canonical GFF JSON and binary conversion
internal/pipeline/ build, extract, compare, and manifest workflows
internal/project/  config loading and repo scanning
internal/validator/validation and diagnostics
tools/             built development binary output
```

## Intended Consumers

- `sow-module` uses `sow-toolkit` for `build-module`, `extract`, `validate`, `compare`, and `apply-hak-manifest`
- `sow-assets` uses `sow-toolkit` for `build-haks` and validation
  - validation now fails early if duplicate asset resources would collide inside the same generated HAK
  - duplicate resources split across different HAK groups remain warnings because later HAK order can still override earlier content at runtime
- `sow-module` now also uses `sow-toolkit` for topdata:
  - `validate-topdata`
  - `build-topdata`
  - `compare-topdata`
  - `convert-topdata`

During development, sibling repositories can point at `../sow-tools/tools/sow-toolkit`. For pinned releases, each consumer repo can instead carry its own copy at `tools/sow-toolkit`.


## Release Automation

This repo publishes:

- `sow-toolkit-linux-amd64.tar.gz`
- `sow-toolkit-windows-amd64.exe`

Consumer repos can fetch those binaries into their local `tools/` directory with:

- `install-tool.sh` on Linux/macOS
- `install-tool.ps1` on Windows

## TopData

The native topdata system is implemented in this repo and authored in `sow-module`.

High-level ownership split:

- `sow-tools`
  - owns the `sow-toolkit` implementation
  - owns topdata validation, build, compare, conversion, and dataset-resolution logic
- `sow-module`
  - owns canonical topdata authored data under `topdata/data/`
  - owns the user-facing topdata workflow scripts

For a human-readable front-to-back explanation of how the native topdata builder works
and how to use it, see:

- [sow-module/topdata/README.md](../sow-module/topdata/README.md)

Important topdata contracts still live here under `internal/topdata/` because they are
code-adjacent implementation contracts, not user workflow docs.
