html2text

• [added] Add support for XHTML (for the cases where it doesn't quite behave like HTML).

• [changed] Split html2text example into html2text-cli crate
• [fixed] A possible panic when syntax-highlighting
• [changed] Update html5ever to 0.39.0

• [added] Support <b> tags as bold (thanks amir)
• [changed] Update html5ever to 0.38.0 (thanks mtorromeo)

• [changed] Update html5ever and tendril dependencies.

• [fixed] Fix a subtract with underflow with rowspans and empty rows (thanks mdierksen)

• [fixed] Further fix for RcDom::serialize() when there is a <doctype>.

• [fixed] RcDom::serialize() panicked.
• [changed] Bumped html5ever dependency
• [fixed] Fixed a subtraction underflow in the html2term example.

Remove debug accidentally left in.

• [fixed] Removed spurious dbg!() accidentally left in.

• [added] Add Config::empty_img_mode() to configure how images with no alt text are handled.

• [changed] Updated MSRV to 1.85.
• [fixed] Fix a panic in debug mode (subtraction underflow) with some table/rowspan edge cases (thanks mtorromeo)

• [fixed] Fix an assertion and some missing styles with rowspan cells in rich mode.

• [added] Support handling rowspan in tables.

• [fixed] Parse <noscript> tags as if scripting is disabled (thanks craigchiang)
• [fixed] Treat inline <svg> as images (thanks craigchiang)

• [fixed] Fix whitespace-only tables being shown as "─" (thanks fuelen)
• [fixed] Fix wrapping with non-breaking spaces, zero-width spaces, and some similar equivalents.

• [added] CSS: Support basic attribute selectors (div[attr="bar"]).
• [changed] Various improvements to syntax highlighting:
  • It uses the priority of the x-syntax rule.
  • Now supported on non-<pre> elements.
  • No longer strips contained tags when highlighting
  • Compatible with display: x-raw-dom extension (e.g. to colour the HTML)
• [fixed] With pad_block_width enabled, do a better job of padding blocks. In particular, the padding gets the block's background colour (when CSS etc. are being used).

• [added] Syntax highlighting support for <pre> blocks (Config::register_highlighter and CSS x-syntax: foo)
• [changed] CSS extensions (until now display: x-raw-dom, and only if the css_ext Cargo feature is enabled) are now only available in agent and user CSS. This is a breaking change, but is not likely to affect many users.

• [added] RcDom::serialize, and expose a few more of the RcDom types.
• [added] Online demo page

• [changed] Updated dependencies, including html5ever 0.31.

• [fixed] An issue with multiple verions of markup5ever being included. (thanks anna-hope)

• [fixed] An infinite loop if tabs inside <pre> wrapped past the width (thanks nshp)

• [changed] Various small refactors (thanks sftse)
• [changed] Config::rich() no longer includes decorations around <em> etc. - use Config::rich().do_decorate() to get the old behaviour.
• [fixed] Remove unnecessary empty lines at the start of lists (thanks russellbanks)
• [added] New CSS support: ::before/::after and content: "string", which is now used for simple decorations. With CSS enabled, this allows for customising the display of <em>foo</em> without writing a decorator.
• [added] Add support for <h5> and <h6> (thanks noahbaculi)
• [changed] Link footnotes are now configurable independently of the decorator, and on by default for config::plain() but can be enabled or disabled with config.link_footnotes(true/false). The footnote references (e.g. [1]) are added in the main renderer, and the actual footnotes are written in a default implementation of TextDecorator::finalise() so can be customised.

• [fixed] Fixed issue parsing CSS rules with known rules but unknown values, which caused parsing to stop instead of just skipping the unkown rule.

• [added] CSS support for :nth-child() (not yet with the of foo).
• [added] Non-standard display: x-raw-dom for debugging (with css_ext feature flag).
• [fixed] An issue which could (apparently rarely) miss out some output depending on wrapping

• [fixed] Some edge cases with CSS styles on whitespace

• [added] Support CSS white-space: pre-wrap (and normal, pre).

• [changed] Updated html5ever and markup5ever crate versions. This has meant updating the MSRV, which is now set to 1.72.
• [fixed] Add Config::no_link_wrapping() (thanks JadeBlueEyes)
• [fixed] Fix panic with empty table inside a list (thanks sftse)
• [changed] Top level convenience functions (from_read etc.) now return Result<..> instead of panicking (thanks sftse)
• [fixed] Fix panic with very large HTML colspan (thanks pycui)
• [changed] CSS updates:
  • Separate user agent, author, and user CSS layers
  • Improve the style precedence between layers and implement specificity.

• [fixed] Table rows with colours would disappear. (thanks tkapias)

• [changed] Replaced LightningCSS with a smaller CSS parser. There is a chance that some CSS edge cases which no longer work; if so this would be a bug.

• [removed] Some previously pub items and methods which are either internal implementation details or considered redundant have been removed or made private (thanks sftse). Please open an issue for anything removed that was being used.

  Of note, RenderTree::render_plain() and RenderTree::render_rich() have been removed. Replace code like:

  let text = html2text::parse(html)?
      .render_plain(80)?
      .into_string()?;
  

  with:

  let text = html2text::config::plain()
      .render_to_string(html2text::parse(html)?)?
  

• [changed] Some names moved out of text_renderer module, so some use statements may need updating.

• [changed] Replace some unwrap() with improved patterns (thanks sftse).

• [changed] Updated some dependencies

• [changed] Updated some dependencies
• [added] The html2text example now has --ignore-css-colour, which ignores CSS colour information but still uses display: none, for example.
• [added] The html2text example now has --only-css option, to not use default colours when CSS colours are being used.
• [fixed] Make the dummy dashmap depenency optional so it's not included unnecessarily when CSS isn't enabled (thanks xmakro)

• [changed] Update the previous max-height: 0 to also look at height: 0 and require overflow: hidden as well. This helps with a hack some e-mail senders use for e-mail previews. (thanks tkapias)

• [changed] Treat max-height: 0 as if it's display: none when CSS is enabled. This helps with a hack some e-mail senders use for e-mail previews. (thanks tkapias)

• [changed] Bump version of lightningcss dependency to fix build failures.

• [fixed] CSS: rules marked !important were ignored.
• [changed] html_trace feature now uses the log crate.

• [changed] Improve layout of tables thanks to sftse:
  • Table column size estimates have been improved when the source HTML has a lot of unnecessary whitespace.
  • Move the URL footnotes out to the top level, also improving layout of tables containing links.
