Kotlin a little too hard.

 Public Fun readbloghtml (blog:string): observable<string> {    return  Observable.just (blog                    ), assembleurl (blog)}                    , readhtml (URL)}}

I was a little confused ...

And in fact Flatmap is not needed, because Kotlin read the source of the Web page is a word ...

 Public Fun readhtml (url:string): observable<string> {    return Observable.create<string> {        - subscriber.onnext (URL). ReadText ()); Subscriber.oncompleted ()    }}

It's better not to observable ...

And so it becomes this:

 Public Fun readbloghtml (blog:string): observable<string> = observable.just (blog)                    , assembleurl (blog)}                     readhtml (URL)}private fun Assembleurl (blog:string?): String = "//$blog. tumblr.com/page/ Public Fun readhtml (url:string): String = URL (url). ReadText ()

Do you want to write this code again?

Huh?

Rxjava No More ...

can become this:

Fun Test () {    Async {        = readbloghtml ("blog")        uithread {update (HTML)    }}} public Fun readbloghtml (blog:string): String = readhtml (assembleurl (blog))private Fun Assembleurl ( Blog:string?): String = "http://$blog . tumblr.com/page/" Public Fun readhtml (url:string) string = URL (url). rea Dtext ()

Ah??
