I'm currently an undergraduate at the University of Maryland and am starting a project using Ur/Web. I was wondering if there was a standard library for file reading and writing. I had read previously that users were expected to use C FFI for this functionality, but perhaps things have changed since then.
As Marc noted, standard file IO APIs are incompatible with Ur/Web's transactional model. I'm not a big fan of files, in any context. If you explain what your underlying goal is, then we may be able to suggest good ways to achieve it in Ur/Web.
One more thing I noticed is I get the following error when including "©" in xml tags: Unsupported XML character entity copy Parse failure I believe that this should be valid html.
The error message isn't meant to suggest it's invalid HTML, but merely that the Ur/Web lexer doesn't support it yet. I could copy-and-paste a table of all valid HTML entities into the Ur/Web lexer/parser source code. Is that the best way to support all these little shorthands? (You're not losing expressive power, as far as I know, since the "&#NNN;" form is already supported.)
