Render a mustache template.

Renders a mustache template with a data scope and inline partial capability.

Arguments:

template – A file-like object or a string containing the template

data – A python dictionary with your data scope

partials_path – The path to where your partials are stored

If set to None, then partials won’t be loaded from the file system (defaults to ‘.’)

partials_ext – The extension that you want the parser to look for

(defaults to ‘mustache’)

partials_dict – A python dictionary which will be search for partials

before the filesystem is. {‘include’: ‘foo’} is the same as a file called include.mustache (defaults to {})

padding – This is for padding partials, and shouldn’t be used

(but can be if you really want to)

def_ldel – The default left delimiter

(“{{” by default, as in spec compliant mustache)

def_rdel – The default right delimiter

(“}}” by default, as in spec compliant mustache)

scopes – The list of scopes that get_key will look through

warn – Log a warning when a template substitution isn’t found in the data

keep – Keep unreplaced tags when a substitution isn’t found in the data

Returns:

A string containing the rendered template.
