A python implementation of the mustache templating language.

Why chevron?

I'm glad you asked!

chevron is fast

Chevron runs in less than half the time of pystache (Which is not even up to date on the spec).
And in about 70% the time of Stache (A 'trimmed' version of mustache, also not spec compliant).

chevron is pep8

The flake8 command is run by travis to ensure consistency.

chevron is spec compliant

Chevron passes all the unittests provided by the spec (in every version listed below).

If you find a test that chevron does not pass, please report it.

chevron is Python 2 and 3 compatible

Python 2.6, 2.7, 3.2, 3.3, 3.4, 3.5, and 3.6 are all tested by travis.

                        The default right delimiter, "}}" by default.

Python usage with strings

import chevron

chevron.render('Hello, {{ mustache }}!', {'mustache': 'World'})

Python usage with file

import chevron

with open('file.mustache', 'r') as f:
    chevron.render(f, {'mustache': 'World'})

Python usage with unpacking

import chevron

args = {
  'template': 'Hello, {{ mustache }}!',

  'data': {
    'mustache': 'World'
  }
}

chevron.render(**args)

chevron supports partials (via dictionaries)

import chevron

args = {
    'template': 'Hello, {{> thing }}!',

    'partials_dict': {
        'thing': 'World'
    }
}

chevron.render(**args)

chevron supports partials (via the filesystem)

import chevron

args = {
    'template': 'Hello, {{> thing }}!',

    # defaults to .
    'partials_path': 'partials/',

    # defaults to mustache
    'partials_ext': 'ms',
}

# ./partials/thing.ms will be read and rendered
chevron.render(**args)

chevron supports lambdas

import chevron

def first(text, render):
    # return only first occurance of items
    result = render(text)
    return [ x.strip() for x in result.split(" || ") if x.strip() ][0]

def inject_x(text, render):
    # inject data into scope
    return render(text, {'x': 'data'})

args = {
    'template': 'Hello, {{# first}} {{x}} || {{y}} || {{z}} {{/ first}}!  {{# inject_x}} {{x}} {{/ inject_x}}',

    'data': {
        'y': 'foo',
        'z': 'bar',
        'first': first,
        'inject_x': inject_x
    }
}
