[subbu@earth mwvagrant] parse.js --html2wt < /tmp/html
[error/html2wt/link][enwiki/Main Page] Bad title text <a href=";platform=all-access&amp;agent=all-agents&amp;range=last-month&amp;pages=Wikipedia:VisualEditor|Wikipedia:VisualEditor/User_guide">foobar</a>

  flush (/home/subbu/work/wmf/deploy/node_modules/babybird/node_modules/asap/raw.js:50:29)
  process._tickCallback (node.js:415:13)

Looks like some test / regexp for whether the link should be serialized as a wikilink / extlink is broken ... it tries to serialize it as a wikilink for some weird reason and encounters a bad title text error.

@Esanders, I don't think it is related to a pipe

[subbu@earth mwvagrant] echo '<a href="|y">foo</a>' | parse.js --html2wt
[|y foo]
