LibWeb: Start building the tree building part of the new HTML parser This patch adds a new HTMLDocumentParser class. It keeps a tokenizer object internally and feeds itself with one token at a time from it. The names and idioms in this class are expressed as closely to the actual HTML parsing spec as possible, to make development as easy and bug free as possible. :^) This is going to become pretty large, but it's pretty cool!

~HTMLDocumentParser();
LibWeb: Implement encoding sniffing algorithm This patch implements the HTML specification's "encoding sniffing algorithm", which is used when no encoding can be obtained from the Content-Type header (either because it doesn't contain a charset=...) value or the file has not been opened via HTTP (as with local files). It also modifies the creator of the HTMLDocumentParser to use the new HTMLDocumentParser::create_with_uncertain_encoding static method, which runs the encoding sniffing algorithm before instantiating the parser. This now allows us to load local HTML pages (or remote pages without a charset specified in the 'Content-Type' header) with a non-UTF-8 encoding such as 'windows-1252'. This would previously crash the browser. :^)

It says that if it occurs when not parsing a fragment, then it is a specification error. We should probably assume at this point that it's an implementation error. This fixes a few little mistakes that were caught out by this. Also moves the context element outside insertion mode reset, as other (unimplemented) parts refer to it, such as "adjusted current node". Also cleans up insertion mode reset.

LibWeb: A whole bunch of work towards spec-compliant <script> elements This is still very unfinished, but there's at least a skeleton of code.

LibWeb: Bring up basic external script execution in the new parser This only works in some narrow cases, but should be enough for our own welcome.html at least. :^)

LibWeb: Add a way to stop the new HTML parser Some things are specced to "stop parsing", which basically just means to stop fetching tokens and jump to "The end"

LibWeb: Start building the tree building part of the new HTML parser This patch adds a new HTMLDocumentParser class. It keeps a tokenizer object internally and feeds itself with one token at a time from it. The names and idioms in this class are expressed as closely to the actual HTML parsing spec as possible, to make development as easy and bug free as possible. :^) This is going to become pretty large, but it's pretty cool!

LibWeb: Make HTMLDocumentParser take an existing document We shouldn't really be creating the document objects inside the parser, since that makes it hard to hook up e.g JavaScript bindings early on.

LibWeb: Move DOM classes into the Web::DOM namespace LibWeb keeps growing and the Web namespace is filling up fast. Let's put DOM stuff into Web::DOM, just like we already started doing with SVG stuff in Web::SVG.

LibWeb: Buffer text node character insertions in the new parser Instead of appending character-at-a-time, we now buffer character insertions in a StringBuilder, and flush them to the relevant node whenever we start inserting into a new node (and when parsing ends.)
