I am building a custom Javascript-Like custom language plugin. This custom language will be based on Ecmascript 6/Javascript. I want to add extra custom tags and keywords on top of Javascript. Most importantly, I want to make my code syntax highlighting look the same as Javascript together with auto-complete etc. I tested syntax highlighting with the Java Language and it worked.
Inside my MyScriptLanguage.java file I added this constructor and highlighting worked after debugging my plugin:
protected MyScriptLanguage() {
super(JavaLanguage.INSTANCE, "MyScript", "text/ms", "application/ms");
}
Then I switched to the Javascript Language like this:
protected MyScriptLanguage() {
super(JavascriptLanguage.INSTANCE, "MyScript", "text/ms", "application/ms");
}
After switching on to Javascript debug stopped working with some language conflict errors (Language with ID 'JavaScript' is already registered: class com.intellij.lang.javascript.JavascriptLanguage) below:

Can someone help me out. I just need to extend the Javascript highlighting and Autocomplete functions on top of my own custom ones.
