* QTextMarkdownWriter: write fenced code blocks with language declarationShawn Rutledge2019-06-041-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MD4C now makes it possible to detect indented and fenced code blocks: Fenced code blocks have the advantages of being easier to write by hand, and having an "info string" following the opening fence, which is commonly used to declare the language. Also, the HTML parser now recognizes tags of the form <pre class="language-foo"> which is one convention for declaring the programming language (as opposed to human language, for which the lang attribute would be used): So it's possible to read HTML and write markdown without losing this information. It's also possible to read markdown with any type of code block: fenced with ``` or ~~~, or indented, and rewrite it the same way.

* Markdown: blockquotes, code blocks, and generalized nestingShawn Rutledge2019-05-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Can now detect nested quotes and code blocks inside quotes, and can rewrite the markdown too. QTextHtmlParser sets hard-coded left and right margins, so we need to do the same to be able to read HTML and write markdown, or vice-versa, and to ensure that all views (QTextEdit, QTextBrowser, QML Text etc.) will render it with margins. But now we add a semantic memory too: BlockQuoteLevel is similar to HeadingLevel, which was added in 310daae53926628f80c08e4415b94b90ad525c8f to preserve H1..H6 heading levels, because detecting it via font size didn't make sense in QTextMarkdownWriter. Likewise detecting quote level by its margins didn't make sense; markdown supports nesting quotes; and indenting nested quotes via 40 pixels may be a bit too much, so we should consider it subject to change (and perhaps be able to change it via CSS later on). Since we're adding BlockQuoteLevel and depending on it in QTextMarkdownWriter, it's necessary to set it in QTextHtmlParser to enable HTML->markdown conversion. (But so far, nested blockquotes in HTML are not supported.) Quotes (and nested quotes) can contain indented code blocks, but it seems the reverse is not true (according to ) Quotes can contain fenced code blocks. Quotes can contain lists. Nested lists can be interrupted with nested code blocks and nested quotes. So far the writer assumes all code blocks are the indented type. It will be necessary to add another attribute to remember whether the code block is indented or fenced (assuming that's necessary). Fenced code blocks would work better for writing inside block quotes and list items because the fence is less ambiguous than the indent. Postponing cursor->insertBlock() as long as possible helps with nesting. cursor->insertBlock() needs to be done "just in time" before inserting text that will go in the block. The block and char formats aren't necessarily known until that time. When a nested block (such as a nested quote) ends, the context reverts to the previous block format, which then needs to be re-determined and set before we insert text into the outer block; but if no text will be inserted, no new block is necessary. But we can't use QTextBlockFormat itself as storage, because for some reason bullets become very "sticky" and it becomes impossible to have plain continuation paragraphs inside list items: they all get bullets. Somehow QTextBlockFormat remembers, if we copy it. But we can create a new one each time and it's OK. Change-Id: Icd0529eb90d2b6a3cb57f0104bf78a7be81ede52 Reviewed-by: Gatis Paeglis <>
* Change QTextMarkdownWriter to pass by const pointer and QAIMShawn Rutledge2019-05-081-2/+2

* Markdown: fix several issues with lists and continuationsShawn Rutledge2019-05-081-0/+11
| | | | | | | | | | | | | | | | | | | | Importer fixes: - the first list item after a heading doesn't keep the heading font - the first text fragment after a bullet is the bullet text, not a separate paragraph - detect continuation lines and append to the list item text - detect continuation paragraphs and indent them properly - indent nested list items properly - add a test for QTextMarkdownImporter Writer fixes: - after bullet items, continuation lines and paragraphs are indented - indentation of continuations isn't affected by checkboxes - add extra newlines between list items in "loose" lists - avoid writing triple newlines - enhance the test for QTextMarkdownWriter Change-Id: Ib1dda514832f6dc0cdad177aa9a423a7038ac8c6 Reviewed-by: Gatis Paeglis <>
* Add QTextMarkdownWriter::writeTable(QAbstractTableModel)Shawn Rutledge2019-05-021-0/+2
| | | | | | | | | | This provides the ability to write live data from a table to Markdown, which can be useful to load it into a text document or a wiki. But so far QTextMarkdownWriter is still a private class, intended to be used experimentally from QtQuick and perhaps later exposed in other ways.

A QTextDocument can now be written out in Markdown format. - Add the QTextMarkdownWriter as a private class for now - Add QTextDocument::toMarkdown() - QTextDocumentWriter uses QTextMarkdownWriter if setFormat("markdown") is called or if the file suffix is .md or .mkd - Add QTextEdit::toMarkdown() and the markdown property [ChangeLog][QtGui][Text] Markdown (CommonMark or GitHub dialect) is now a supported format for reading into and writing from QTextDocument.
