# User:CRGreathouse/lang tags

This report (last run Mar 29 2012) is based on the output of Rosetta Code/Find bare lang tags and gives instances of <lang> tags on pages. The results of the run were encouraging: over 98% of the code snippets were marked with language names. C is the worst offender with 64 (about 10%) bare <lang> tags, probably because many of its outputs are coded with <lang> rather than <pre>.

Compared to last year, this represents a serious improvement. There are two dark spots, though: it seems that many new CoffeeScript and Mercury programs have been added which do not have lang tags. These should be fixed!

See Help:Syntax Highlighting for a list of language codes.
