Lexbor Files

Hello,

I'm glad to announce a new release of Lexbor library.

Major improvements/changes in version 2.7.0:

• Amalgamation - added support for amalgamation (combining source files into a single file). Simplifies embedding the library into projects — just connect one file instead of the entire build system. See the documentation for details: https://lexbor.com/amalgamation/
• Major refactoring of CSS Parsing code to prepare for layout.
• Added validation of incoming stream in HTML parser (this is only needed to output parse errors according to the specification). Disabled by default. See: https://lexbor.com/modules/html/#tokenizer-options
• General code preparation for the release of the layout engine.
• General improvements and bug fixes.

Added

• Added amalgamation support.
• Encoding: added prescan validation and BOM sniffing functions.
• HTML: added lxb_html_encoding_prescan() function.
• HTML: added scope categories to <select> element per specification.
• HTML: added descriptions for Tree Builder and Tokenizer errors.
• DOM: added lxb_dom_node_type() function.
• Build: added -DLEXBOR_TEST_AMALGAMATION.
• Test::HTML: added chunks tests for html5lib tests.
• Test::HTML: added more html5lib tests.

• CSS::Syntax: fixed integer overflow when parsing number exponent.
• CSS::Syntax: fixed undef token instead of URL token.
• Style: fixed use-after-free when destroying multiple stylesheets.
• Selectors: fixed returning state if not found in nth-child().

• URL: fixed "use-after-poison" for an empty path entry.
• URL: the cloning function does not copy the type for IPv4 and IPv6.
