flexmark-ext-toc SimTocExtension ignores TITLE_LEVEL > 1 (patch included)

[maassg]

Version flexmark-all-0.62.2

SimTocExtension ignores TITLE_LEVEL > 1 like this: [TOC levels=3-5]: ### "A Title"

Title level > 1 can only be set via Parser option, e.g.: options.set( SimTocExtension.TITLE_LEVEL, 3 );

In my opinion the following 2 classes are responsible for this bug:

• com.vladsch.flexmark.ext.toc.internal.SimTocBlockParser
• com.vladsch.flexmark.ext.toc.SimTocBlock

The corrected versions can be found in the appendix.

The changes are as follows:

• com.vladsch.flexmark.ext.toc.internal.SimTocBlockParser

  class TocParsing: changed Pattern from  ...#(... to  ...#+(...
  changed constructor to:
  SimTocBlockParser( MutableDataHolder options, ... ) {
     block = new SimTocBlock(tocChars, styleChars, titleChars);
     options.set( SimTocExtension.TITLE_LEVEL, block.getTitleLevel() );
     this.options = new TocOptions( options, true );
  } 
  

• com.vladsch.flexmark.ext.toc.SimTocBlock

  changed constructor to:
  public SimTocBlock(BasedSequence chars, BasedSequence styleChars, BasedSequence titleChars) {
     ...
     // anchorMarker = chars.subSequence(anchorPos, anchorPos + 1);
     int anchorEndPos = anchorPos+1;
     for( ; chars.charAt(anchorEndPos) == '#'; anchorEndPos++ );
     if( anchorEndPos - anchorPos > 6 ) {
        throw new IllegalStateException( "Invalid TOC block sequence: " + chars.subSequence( anchorPos) );
     }
     anchorMarker = chars.subSequence( anchorPos, anchorEndPos );
     ...
  }
  added method:
  public int getTitleLevel() {
      return anchorMarker.length();
  }
