* docs: standardise language naming and add binding security sections
Canonical binding list everywhere: Rust, Python, Node.js, WASM, C, C++, C#,
Go, Java, R. Use C# (not .NET) as the language label, WASM (not WebAssembly)
in prose, and frame the C ABI as a hub rather than a list item.
- Bump stale indicator counts (200+ -> 514) and family count (sixteen ->
twenty-four) in the Node/Python/WASM and docs READMEs.
- Add a short Security section to all eight binding READMEs.
- Relabel benchmark rows (C -> C / C++, C# / .NET -> C#).
- Fix the 'language stecker' wording in the C#/Go/R API intros.
- Documentation only; no code or public API changes.
* release.yml: extend install snippets and expose version output
Add the missing registry installs to the release body (dotnet, go, Gradle/
Maven Central, r-universe) alongside cargo/pip/npm, and expose a v-stripped
'version' output from the tag step for the Gradle coordinate. Also fix the
C-ABI language order in the assets note (C# before Go).
* release.yml: correct the release body (10 languages, all registries)
Reframe the tagline to '10 languages' (native Rust/Python/Node.js/WASM + a C
ABI hub for C, C++, C#, Go, Java, R) instead of '4 language registries', note
that C#/Java/Go/R publish to NuGet/Maven/Go/r-universe via their own jobs, and
tidy the Node.js label and the C-ABI hub list.
The first language stecker on the C ABI hub: a .NET binding exposing all 514
indicators as idiomatic `IDisposable` classes, generated from `wickra.h`.
## What's here
- **`bindings/csharp/`** — the `Wickra` .NET 8 package. `[LibraryImport]`
source-generated P/Invoke (`NativeMethods.g.cs`) plus idiomatic wrappers
(`Indicators.g.cs`), both generated from the committed `bindings/c/include/wickra.h`.
The binding owns no indicator maths — it only marshals types across the C ABI.
- **Marshalling, verified end-to-end against the native library.** Opaque handles
cross as `nint` kept alive per call via a `SafeHandle`; `bool` as
`[MarshalAs(U1)]` (Rust `bool` is one byte); a self-correcting
`DllImportResolver` validates the loaded library actually exports the Wickra
ABI. Tests cover one representative per FFI archetype (scalar, candle, pairwise,
multi-output, bars, profile, values-profile, order-book / array-input) plus
exact Sma reference values.
- **NuGet packaging** — `dotnet pack` produces `Wickra.<version>.nupkg`; the
release pipeline stages prebuilt native libraries under `runtimes/<rid>/native/`
for six target triples (win/linux/osx × x64/arm64).
- **`examples/csharp/`** — nine examples mirroring `examples/c/`: streaming,
backtest, multi_timeframe, parallel_assets, three strategies, and
fetch_btcusdt + live_binance.
- **CI** — a `csharp` job on the three OSes builds the C ABI, tests the binding,
and runs the offline examples. **Release** — a gated `csharp-publish` job packs
and pushes to NuGet (gated on `NUGET_API_KEY`, independent of the GitHub-release
job so a C# hiccup never blocks the C/C++ asset release).
- **Docs consistency wave** — README, CONTRIBUTING, CHANGELOG, examples/README,
the issue / PR templates, `sync-about.yml`, and `.gitattributes`.
The native Python / Node / WASM bindings and the C ABI are untouched; this is
additive. Publishing to NuGet stays gated behind the release tag and the secret.
