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]).
