I am writing component for viewing huge files > 4 GiB, which are not loaded to memory. (https://github.com/siplasplas/qt-textviewer)
I want add syntax highlighting (and maybe folding), but I can’t use QTextDocument because my fro ground widget not keep whole text in memory and number lines is unknown. Also I can’t probably use KsyntaxHighlighting::SyntaxHighlighter because it requires QtextDocument I wanna use KsyntaxHighlighting::Repository, KsyntaxHighlighting::Definition and KSyntaxHighlighting::Format. Definition has methods/fields such as foldingEnabled or multiLineCommentMarker. Format has method returning at once text styles for thema, and I can’t find methods for rules, for example rule to detect int decimal or octal or string. I have cloned https://invent.kde.org/frameworks/syntax-highlighting,but I can’t find there code to explain me. For example, in SyntaxHighlighter::highlightBlock is ``` const auto nextBlock = currentBlock().next(); if (nextBlock.isValid()) { QMetaObject::invokeMethod(this, "rehighlightBlock", Qt::QueuedConnection, Q_ARG(QTextBlock, nextBlock)); } ``` but I don't find "rehighlightBlock" in any other place in whole repository.
