How can I contact someone, I have problem with custom data and reader. My reader for my data class isn't generated but I don't know why. If you have advice or can help I would appreciate that.

• Update Gradle Versions.
• Update Kotlin from 1.5 to 1.5.30.
• Add KSP processor and provider but valid implementation not yet implemented.

TODO:

• Implement KSP processors and generators.
• Remove KAPT.

Hello, Kotlin 1.5.0-RC is around the corner and I checked if it played nicely with KtRssReader, but due to the new Duration api changes it wasn't happy about it;

java.lang.NoSuchMethodError: No static method getDays(I)D in class Lkotlin/time/DurationKt; or its super classes (declaration of 'kotlin.time.DurationKt' appears in /data/app/~~8tbLKXsRF-XaLJOxrS_dhQ==/com.example.test.android.app-6jJoF5SXNmXOC7dOK8x6_g==/base.apk!classes26.dex)

I started here: https://github.com/ivanisidrowu/KtRssReader/pull/70 but I havent tried it yet since I couldn't figure out where you change the project version so I could publish locally and try it in my own project..

edit: I did some further investigation and its still unclear what causes this crash, only did the problem go away if I uninstalled the kotlin plugin in android studio (canary) and reinstalled the latest stable one via File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle.

Take a look at the feed of Inside Java podcast:

They use HTML markup for descriptions, but they have the same text in itunes:summary and itunes:subtitle, but without any tags. It would be really great to support them.

I noticed that the library seems to work for most part with API version 21. Is there some reason that the minimum version is 23?

Thanks for the nice library.

Description

• Integrate KSP for generating parsers.
• Remove KAPT from KtRssReader completely.
• Update KotlinPoet to 1.10.2.
• Use kotlinpoet-ksp interop lib. https://square.github.io/kotlinpoet/interop-ksp/
• Run and pass all the instrumented and JVM unit tests.

Todo

• Final checks before releasing version 2.2.

Screenshots

此次新增與調整項目

1. 新增 kapt argument 來讓 annotation processor 決定要產生純 Kotlin 或是 Android 的 parser 。
2. 調整 extension generator 和 parser generator 的結構，讓某些功能可以共用。
3. 新增 純 Kotlin annotation processor 的測試，共三個 class ，測項沿用之前的測項。

純。Kotlin Parser Generation

新增用法

在 build.gradle 裡面寫上 kapt 專用的 argument 。

kapt {
    arguments {
        arg("pureKotlinParser", true)
    }
}

這樣就可以讓 annotation processor gen 出純 Kotlin 的 parser 了。 這麼做的好處是可以共用 annotation processor 和 generator 部分功能，不必另開 module 去處理。

Generator 結構調整

Generator   ----> ExtensionGenerator ----> AndroidExtensionGenerator, KotlinExtensionGenerator
<interface>  |
             | -> ParserGenerator    ----> AndroidParserGenerator, KotlinParserGenerator

備註

• 如果想看 gen 出來的 code 可以直接 check out 這麼 branch ，然後 rebuild project，找 TestRssDataParser、RawRssDataParser 或 MixRssDataParser 看看效果。
• 產生的程式碼都在 tw.ktrssreader.generated package 下面。
• Kotlin Poet document: https://square.github.io/kotlinpoet/

• Made 'testCommon' a pure Kotlin module.
• Moved common classes to the kotlin module.
  • ChannelItemTestData: From module android to testCommon.
• Fixed tests.
  • DatabaseRssCacheLocalTest: applicationContext is not initiated.
• Added pure Kotlin parser RssStandardParser in kotlin module.
  • Used JAVA DOMParser to parse XML. I tried SAX and SAtX, but they do not support getting value by specific tags. Even thought it consumes much more memory, but the kotlin module mostly for non-mobile environment. I think it's acceptable.
• Added pure Kotlin parser RssStandardParser tests.

• Renamed parsers in android module by adding prefix "Android".
  • ParserBase -> AndroidParserBase
  • GoogleParser -> AndroidGoogleParser
  • ITunesParser -> AndroidITunesParser
  • AutoMixParser -> AndroidAutoMixParser

Move common classes from the android module to the pure Kotlin module

Classes included...

• PaserConst
• Channel
• Cloud
• Image
• Owner
• TextInput
• Category
• Enclosure
• Guid
• Items
• Source
• Parser

• Add the Gradle artifacts.
• Avoid compiler errors of the generated code for the Kotlin 1.3 users because of the trailing commas and the mixed index function parameters.

It seems that the implementation uses internal (non-exported) classes:

class tw.ktrssreader.kotlin.parser.ParserBase (in unnamed module @0x443effcb) cannot access class com.sun.org.apache.xerces.internal.dom.DeferredElementImpl (in module java.xml) because module java.xml does not export com.sun.org.apache.xerces.internal.dom to unnamed module @0x443effcb
java.lang.IllegalAccessError: class tw.ktrssreader.kotlin.parser.ParserBase (in unnamed module @0x443effcb) cannot access class com.sun.org.apache.xerces.internal.dom.DeferredElementImpl (in module java.xml) because module java.xml does not export com.sun.org.apache.xerces.internal.dom to unnamed module @0x443effcb
	at tw.ktrssreader.kotlin.parser.ParserBase.readString(ParserBase.kt:229)
	at tw.ktrssreader.kotlin.parser.AutoMixParser.parseChannelTags(AutoMixParser.kt:136)
	at tw.ktrssreader.kotlin.parser.AutoMixParser.parse(AutoMixParser.kt:89)

Environment: Java 17, Kotlin 1.7.20
