MarkdownDialectGitHub

[clarify]

The cardinal rule of good programming is, never put unexplained literal numbers in code, because nobody knows what they mean and it causes confusion and "WTF"'s.

Case in point in Qt 5:

    MarkdownDialectGitHub = 0x0004 | 0x0008 | 0x0400 | 0x0100 | 0x0200 | 0x0800

Whatever do these numbers mean? Are they deep secrets that only James Bond can decode?

The "answer" is in class Q_GUI_EXPORT QTextMarkdownImporter https://codebrowser.dev/qt6/qtbase/src/gui/text/qtextmarkdownimporter_p.h.html#QTextMarkdownImporter::Feature

    enum Feature {
        FeatureCollapseWhitespace =       0x0001,
        FeaturePermissiveATXHeaders =     0x0002,
        FeaturePermissiveURLAutoLinks =   0x0004,
        FeaturePermissiveMailAutoLinks =  0x0008,
        FeatureNoIndentedCodeBlocks =     0x0010,
        FeatureNoHTMLBlocks =             0x0020,
        FeatureNoHTMLSpans =              0x0040,
        FeatureTables =                   0x0100,
        FeatureStrikeThrough =            0x0200,
        FeaturePermissiveWWWAutoLinks =   0x0400,
        FeatureTasklists =                0x0800,
        FeatureUnderline =                0x4000,
        // composite flags
        FeaturePermissiveAutoLinks = FeaturePermissiveMailAutoLinks
            | FeaturePermissiveURLAutoLinks | FeaturePermissiveWWWAutoLinks,
        FeatureNoHTML = QTextDocument::MarkdownNoHTML,
        DialectCommonMark = QTextDocument::MarkdownDialectCommonMark,
        DialectGitHub = QTextDocument::MarkdownDialectGitHub
    };

@JonB That would explain why my underlined text is showing up as italic.
Github dialect doesn't have 0x4000.

But Qt 5 doesn't seem to have QTextMarkdownImporter.

And weirdly: MarkdownDialectCommonMark = 0
