[web-devel] questions about hamlet syntax, and yesod-examples-.0.7.0.1

Wed Apr 13 01:35:44 CEST 2011

It is the same syntax. The closing bracket, '>' is optional if there is no
inner text. The principle of hamlet is to make any redundant part of html
optional, and to remove closing tags in favor of indentation. We are
considering always using the closing bracket for examples to make It easier
to digest for newcomers. It also makes for easier use of some html syntax
highlighters (vim works well enough for me).
