Wed Jul 31 11:55:59 BST 2013 Edsko de Vries <edsko@well-typed.com> * Make lexer monadic (avoid use of 'error') Ignore-this: 18ade47907e883b16d1ba5fadd6b6b4d Importing package metadata was failing because the packageAddHook added by the Search feature was parsing the package description, and if this had a lexical error (as far as the Haddock lexer was concerned) it would throw a runtime error which would eventually result in a Internal Error 500 error. The lexical now returns a value in the Either String monad, just like the parser, so that we can run Haddock.tokenise >=> Haddock.parseHaddockParagraphs to savely lex and parse, without worrying about exceptions in pure code.
