Using Plim with bottlepy

How to use plim template, with micro framework

Posted by @krazedkrish on May 16, 2016


Plim is a Python port of Ruby's Slim template language built on top of Mako Templates. It uses Mako's preprocessor feature to translate its syntax into a valid HTML/Mako markup.


Bottle is a fast, simple and lightweight WSGI micro web-framework for Python. It is distributed as a single file module and has no dependencies other than the Python Standard Library.

BTW it is the best framework to be used with Raspberry Pi

Using Plim with Bottle

All you need to do is create a wrapper. Mine is called


import functools
from  bottle import template, view, BaseTemplate, DEBUG

class PlimTemplate(BaseTemplate):
    def prepare(self, **options):
        from mako.template import Template
        from mako.lookup import TemplateLookup
        from plim import preprocessor
        options.setdefault('format_exceptions', bool(DEBUG))
        lookup = TemplateLookup(directories=self.lookup, **options)
        if self.source:
            self.tpl = Template(self.source, preprocessor = preprocessor, lookup=lookup, **options)
            self.tpl = Template(, preprocessor = preprocessor, filename=self.filename, lookup=lookup, **options)

    def render(self, *args, **kwargs):
        for dictarg in args: kwargs.update(dictarg)
        _defaults = self.defaults.copy()
        return self.tpl.render(**_defaults)

plim_template = functools.partial(template, template_adapter=PlimTemplate)
plim_view = functools.partial(view, template_adapter=PlimTemplate)

Then you can use PlimTemplate by importing plim_template, here is an example

# the import lines
from bottlim import plim_template as template, plim_view as view

def index():
    # the view file name is expected to have extension .html
    # in the following case it will use the template file index.html
    return template('index')

If you don't have your index.html in plim template ready. Copy paste these

doctype html
    h1 Hello World
