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

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

Ideally some sort of tool to convert http://syntax.whattf.org/relaxng/ into a xml-omni-datafile is required. Updating https://vim.svn.sourceforge.net/svnroot/vim/vim7/runtime/autoload/xml/html40s.vim looks a bit too painful.

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
