Bumps the workspace from 0.7.9 to 0.8.0 and adds the release-time mirror of the Go module to a standalone `wickra-go` repository. ## release.yml: `go-mirror` job Adds a `go-mirror` job (independent of `github-release`, `needs: c-abi-build`) that on every `v*` tag: - assembles the standalone Go module from `bindings/go` (single-package source + the vendored `include/wickra.h`), - stages the six prebuilt C ABI libraries from the `c-abi-build` artifacts under `lib/<goos>_<goarch>/` (committed in the mirror, unlike the in-repo `lib/.gitignore`), - rewrites `go.mod` to `module github.com/wickra-lib/wickra-go`, - commits and tags the result in `wickra-lib/wickra-go` using the `WICKRA_GO_MIRROR_TOKEN` fine-grained PAT. This makes `go get github.com/wickra-lib/wickra-go` build with no extra steps, closing the gap where the in-repo `bindings/go` module only built inside a full repository checkout. The mirror is a derived artifact, so its bot commit is intentionally unsigned. ## Version bump 0.7.9 -> 0.8.0 Patch never reaches double digits (`0.7.9` -> `0.8.0`). Touchpoints: `Cargo.toml` (+ `Cargo.lock` via build), `bindings/python/pyproject.toml`, `bindings/node/package.json` + 6 platform `npm/*/package.json` + both `package-lock.json` files, `bindings/java/pom.xml` + `examples/java/pom.xml` + Maven/Gradle snippets in `bindings/java/README.md`, and `CHANGELOG.md`. The C# `Wickra.csproj` (version set per tag) and `bindings/c` (inherits the workspace version) are intentionally untouched. Tagging `v0.8.0` (which triggers the publish + the new mirror) stays gated on explicit confirmation.
Wickra examples — Java
Runnable examples for the Wickra Java binding. Each
example is a small main class that uses the org.wickra:wickra artifact and
resolves the native library automatically (from target/release during local
development, or the bundled per-platform library when packaged).
Build the native library and install the binding to your local Maven repo
first, then run any example with the exec plugin:
cargo build -p wickra-c --release
mvn -f bindings/java install -DskipTests
mvn -f examples/java compile
mvn -f examples/java exec:exec -Dexec.mainClass=org.wickra.examples.Streaming
(The exec:exec goal forks a JVM with --enable-native-access=ALL-UNNAMED, the
flag the FFM API needs.)
| Example | What it does | Main class |
|---|---|---|
streaming |
Feed a synthetic price series through SMA / EMA / RSI / MACD tick by tick. | org.wickra.examples.Streaming |
backtest |
Compute a basket of indicators over an OHLCV series and print a summary. | org.wickra.examples.Backtest |
multi_timeframe |
Resample a 1-minute series into 5m / 15m and print an indicator per timeframe. | org.wickra.examples.MultiTimeframe |
parallel_assets |
SMA(20) batch over a panel of assets, serial vs parallel streams, with speedup. | org.wickra.examples.ParallelAssets |
strategy_rsi_mean_reversion |
RSI(14) mean-reversion with a PnL / Sharpe / max-DD summary. | org.wickra.examples.StrategyRsiMeanReversion |
strategy_macd_adx |
MACD crossover entries gated by ADX(14) > 20. | org.wickra.examples.StrategyMacdAdx |
strategy_bollinger_squeeze |
Bollinger-squeeze breakout with an ATR(14) trailing stop. | org.wickra.examples.StrategyBollingerSqueeze |
fetch_btcusdt |
Download real BTCUSDT klines from the Binance REST API into a CSV. | org.wickra.examples.FetchBtcusdt |
live_binance |
Stream live Binance klines through EMA(20) over a WebSocket. | org.wickra.examples.LiveBinance |
fetch_btcusdt and live_binance require network access; the rest run offline
on deterministic synthetic data. Shared helpers (synthetic data, CSV loader,
equity summary) live in MarketData and Equity.
