Support Grammar

RxMarkdown now provides 2 factories to parse markdown, TextFactory and EditFactory .

TextFactory : Supports most of the markdown grammars，but it will destroy the integrity of the content. So, it applies to render in TextView .

EditFactory : Supports some grammars，and it won't destroy the integrity of the content, the parsing speed is faster than TextFactory , So, it applies to real-time preview in EditText .

compile 'com.yydcdut:rxmarkdown:0.0.7'

compile 'io.reactivex:rxandroid:1.2.0'

Configuration

All options in Configuration builder are optional. Use only those you really want to customize.

RxMDConfiguration rxMDConfiguration = new RxMDConfiguration.Builder(context)
        .setDefaultImageSize(100, 100)//default image width & height
        .setBlockQuotesColor(Color.LTGRAY)//default color of block quotes
        .setHeader1RelativeSize(1.6f)//default relative size of header1
        .setHeader2RelativeSize(1.5f)//default relative size of header2
        .setHeader3RelativeSize(1.4f)//default relative size of header3
        .setHeader4RelativeSize(1.3f)//default relative size of header4
        .setHeader5RelativeSize(1.2f)//default relative size of header5
        .setHeader6RelativeSize(1.1f)//default relative size of header6
        .setHorizontalRulesColor(Color.LTGRAY)//default color of horizontal rules's background
        .setInlineCodeBgColor(Color.LTGRAY)//default color of inline code's background
        .setCodeBgColor(Color.LTGRAY)//default color of code's background
        .setTodoColor(Color.DKGRAY)//default color of todo

        .setRxMDImageLoader(new DefaultLoader(context))//default image loader
        .setDebug(true)//default value of debug
        .setOnLinkClickCallback(new OnLinkClickCallback() {//link click callback
        	@Override
        	public void onLinkClicked(View view, String link) {
        	}
        })
        .build();

Usage

EditText , live preview :

RxMarkdown.live(rxMDEditText)
        .config(rxMDConfiguration)
        .factory(EditFactory.create())
        .intoObservable()
        .subscribe();

cancel real-time preview :
```
rxMDEditText.clear();
```

TextView render :

RxMarkdown.with(content, this)
        .config(rxMDConfiguration)
        .factory(TextFactory.create())
        .intoObservable()
        .subscribeOn(Schedulers.computation())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(new Subscriber<CharSequence>() {
            @Override
            public void onCompleted() {}

            @Override
            public void onError(Throwable e) {}

            @Override
            public void onNext(CharSequence charSequence) {
                rxMDTextView.setText(charSequence, TextView.BufferType.SPANNABLE);
            }
        });

Note

RxMDImageLoader

Acceptable URIs examples

"http://web.com/image.png" // from Web
"file:///mnt/sdcard/image.png" // from SD card
"assets://image.png" // from assets
"drawable://" + R.drawable.img // from drawables (non-9patch images)

Custom image loader

public class MDLoader implements RxMDImageLoader {
    @Nullable
    @Override
    public byte[] loadSync(@NonNull String url) throws IOException {
        return new byte[0];
    }
}

Image Size

The image of 320 pixels width and 320 pixels height will display on the screen :
