Can you make it public or add method getTextProcessor()? TextProcessor has a lot of useful methods

Best regards

CodeEditor widget always applies 100 margins, see the code below

Extract from source code
recyclerViewParam.setMargins(0, height - 100, 0, 0);
paramsTxtprocessor.setMargins(0, 0, 0, 100);

Can you set it to 0 instead of 100?

In the project README, you have:

<com.github.ahmadaghazadeh.editor.widget.CodeEditor
            bind:code="<html></html>"
            bind:lang="html"
            bind:isReadOnly="true"
             bind:isShowExtendedKeyboard="false"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

However, this is invalid XML. That HTML needs to be escaped:

<com.github.ahmadaghazadeh.editor.widget.CodeEditor
            bind:code="&lt;html&gt;&lt;/html&gt;"
            bind:lang="html"
            bind:isReadOnly="true"
             bind:isShowExtendedKeyboard="false"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

When installing on some devices listed below, an extra white bar appears between the default keyboard and the extended one.

Hello,

i have a problem with the following code snipped:

codeEditor = findViewById(R.id.codeeditor);
codeEditor.setText("TEST", 1);
codeEditor.getText(); // method getText() returns "TESTTEST"

The text which gets returned is doubled.
Am i doing something wrong or is this a bug?

Regards

Give some descriptions on this library. It is hard to understand how to use this library. Sample app is also hard because of view bindings and models. Make it easier!

Hi

lineNumbers is in TextProcessor， so GutterView is useless?
