Adding a parser

Add a class that extends MerchantParser, then register it in MerchantRegistry.builtInParsers.

ExampleMerchantParser.kt

object ExampleMerchantParser : MerchantParser() {
    override val merchantId = "merchant_id"
    override val displayName = "Merchant Name"
    override val merchantPackages = listOf("package.name.merchant")

    private val successKeywords = listOf("qris", "success", "paid")
    private val ignoreKeywords = listOf("failed", "refund", "promo")

    override fun parse(notification: ObservedNotification): QrisPaymentEvent? {
        // Implement merchant-specific parsing here.
        return null
    }
}

Code lives in app/src/main/java/io/github/suriyadi15/qrishook/merchant/. Use an existing parser (e.g. GoPayMerchantParser.kt) and its tests under app/src/test/.../merchant/ as a reference. Run ./gradlew testDebugUnitTest before opening a pull request.
