Making your editor suck less for editing Web content

Emacs

XHTML5 or polyglot documents

Emacs ships with nxml-mode, a major mode for editing XML which does on-the-fly validation with RELAX NG schema. You can plug fantasai and hsivonen's schema into nxml-mode. The necessary shim code is included in the hober/html5-el project on github.

HTML5 text/html syntax

As of July 2009, none of the several major modes for editing HTML have special support for HTML5 elements, attributes, or syntax.

https://vim.svn.sourceforge.net/svnroot/vim/vim7/runtime/autoload/xml/ and :help xml-omni-datafile might help you get started.

vim

See the HTML5 conformance checking in Vim blog entry for an introduction.

Idea is to integrate Web services via curl with your editor that supports Validator.nu_GNU_Output, e.g. vim:

• HTML validation with validator.nu script
• JavaScript validation with JSlint script - service source
• CSS validation is being worked on

Quick setup

nox:~/.vim/ftplugin% svn co http://svn.natalian.org/projects/html5/ .
nox:~/.vim/ftplugin% sudo ln -s `pwd`/validate-html.sh /usr/bin/validate-html.sh
nox:~/.vim/ftplugin% sudo ln -s `pwd`/validate-js.sh /usr/bin/validate-js.sh

Improving the scripts

Any suggestions? Please get in contact with hendry

Caveats:

• Vim's makeprg syntax requires some horrible escaping, hence the need for an external script
• Vim's errorformat has issues parsing anything too complex, so best edit the stream for the errorformat (not the other way around)
• Vim's quickfix list (:cope) seems to require a filename (%f) in the error format
