Welcome to herml, the Haml-like templating language! Building: 1) Install leex 0.3 or greater. (Putting it in your $ERLANG_HOME/lib is best) 2) Clone the herml repo from Github. 3) Run make 4) Put the herml/ebin directory somewhere on your code path: 4a) Symlink the top-level herml directory into your $ERLANG_HOME/lib directory -or- 4b) Use the -pz or -pa switches on erl to place herml/ebin onto your code path Using in Sinan: 1) Clone the herml repo from Github 2) Run `make special` in the herml directory 3) Make sure your sinan project can find the herml repo 3a) Clone inside your projects lib directory -or- 3b) Symlink the herml directory to your projects lib directory 4) Keep it up to date: a) Pull down latest changes b) `make clean` c) `make special` Running tests: 1) Run make clean tests Using herml: The interface for herml is a work-in-progress currently. Eventually herml will sport a slick n' simple interface but, for now, its' a two step process: 1) 'Compile' your herml template using herml_parser: 1> CompiledTemplate = herml_parser:file("/path/to/template/file.herml"). Note: You can cache the compiled template and use it over and over. 2) 'Execute' the compiled template using herml_htmlizer: 2> Result = herml_htmlizer:render(CompiledTemplate, Env). Note: Env is a proplist containing the execution environment for the template. herml expects all variable names to be Erlang strings. For example, here's a valid environment proplists: [{"UserName", "herml"}]. The UserName variable would be referenced from herml as @UserName. Another note: herml_htmlizer returns iolists when it executes templates. This is for efficiency reasons. If you want to view the template output as a standard string, you can use the io module to flatten the iolist: 3> io:format("~s", [Result]).
