Create simple websites fast, now.

Poole is an easy to use Markdown driven static website generator. You write
the content of your pages in Markdown and Poole creates a nice and simple site
with a navigation menu. You don't need to learn a template or preprocessing

Though Poole is made for simple sites, it has basic support for content
generation by embedding Python code in page source files. This is a dirty merge
of content and logic but for simple sites it's a pragmatic way to get things
done fast and easy -- if you know Python you're ready to start.

Build status


You should know Markdown and optionally Python if you want to use Poole's
dirty content generation capability.

Your system should have installed Python ≥ 2.7 and python-markdown.
Poole has been tested on Linux but should also work on other Unix systems and
Windows (in theory, report an issue if it fails).

Getting Started

Clone or download (zip, tgz) the repository and then put
poole.py to your PATH:

$ hg clone http://bitbucket.org/obensonne/poole/ /some/where/poole
$ export PATH=$PATH:/some/where/poole

TIP: You might want to add the last command to your ~/.bashrc.

Python3: Download the packages from the py3 branch (zip,
tgz) or check out the py3 branch when cloned.

Create and build a site project:

$ mkdir /path/to/site/project
$ cd /path/to/site/project
$ poole.py --init --theme minimal
$ poole.py --build
$ poole.py --serve

Done. You've just created a website! Browse http://localhost:8080/ and watch
the example pages which have been created during initialization. To write your
own pages, use the example pages in the input folder as a starting point.

Next to the miniaml theme, there are some other choices available.

Run poole.py --build whenever you've made some changes in the input folder.

How It Works

Poole takes files from a project's input directory and copies them to the
output directory. In this process files ending with md, mkd, mdown or
markdown get converted to HTML using the project's page.html as a template
(unless a custom template is set on an individual page).

Additionally Poole expands any macros used in a page. Don't care about that for
now ..

When running poole.py --build in a Poole project, an input directory like

|- input
    |- index.md
    |- news.mkd
    |- foo.mdown
    |- images
        |- bar.png

will result in an output folder like that:

|- output
    |- index.html
    |- news.html
    |- foo.html
    |- images
        |- bar.png

Page Layout

Every Poole page is based on the skeleton file page.html. Hence adjusting the
site layout means adjusting page.html and extending or replacing its CSS file

The only thing you should keep in page.html are the embedded
{{__content__}} and {{__encoding__}} expressions. Below is an almost
minimal page.html file. It does not look nice but it's a clean starting point
to build your own layout from scratch.

Minimal page.html:

    <meta http-equiv="Content-Type" content="text/html; charset={{ __encoding__ }}" />
    {{ __content__ }}

It's easy to apply one of the numerous free CSS templates out there to a Poole
site. For more information read this blog post with step-by-step

In case you need special templates for individual pages, you can add the
property tempalte in the front matter of each page:

title: This looks different
template: a-special-page-template.html

In that case the given file is used as the page template instead of the default
page.html file.

Content Generation

Poole allows you to embed Python code in your pages to generate content:


Here is normal text in *markdown* flavor.
print "hello poole"
Did you know? The sum of 2 and 2 is {{ 2 + 2 }}.

This example demonstrates two ways to embed Python code, either as statements or
as expressions:

  1. Everything between {% and %} are statements and whatever is printed
    to stdout during their execution is going to be part of the final HTML
  2. Everything between {{ and }} are expressions and their evaluation is
    going to be part of the final page.

TIP: Instead of the outer curly brackets { and } you can also use
<!-- and --> to prevent syntax highlighting markdown editors from getting
confused by the Python code.

TIP: To print the code surrounding tags literally, simply escape the
opening tag with a backslash.

Outsource complex or frequently used code

To keep embedded code short and compact or to reuse it in several pages, it can
be outsourced into a file called macros.py in a project's root folder (where
the page.html file is located). Every public attribute in macros.py is
available within embedded Python code blocks:


from datetime import date
def today():
    return date.today().strftime("%B %d, %Y")

author = "Popeye"


This site has been updated on {{ today() }} by {{ author }}.

Builtin macros

Builtin macros can be used from the macros module as well as from python
code in your pages and templates (just as if they are defined within
your macros.py).

Currently, there is only one builtin macro available.


Replace the characters that are special within HTML (&, <, > and ")
with their equivalent character entity (e.g., &amp;). This should be
called whenever an arbitrary string is inserted into HTML (i.e. use
{{ hx(variable) }} instead of {{ variable }}). You do not need this
within a markdown context.

Note that " is not special in most HTML, only within attributes.
However, since escaping it does not hurt within normal HTML, it is
just escaped unconditionally.

Working with pages

Next to stuff defined in macros.py the objects page and pages are
available in embedded Python code. The first one is a dictionary describing the
page in which the code is embedded. The second one is a list of all pages in
the project.

The following attributes are always set in a page dictionary:

  • title: The page's title, by default its filename without extension
    (setting alternatives is described in the next section).
  • fname: Path to the page's source file, e.g.
  • url: The page's relative URL, e.g. for a source page
    input/stuff/news.md this is stuff/news.html.

The example page.html file in a freshly initialized site project uses a
page's title attribute:

<div id="header">
     <h1>a poole site</h1>
     <h2>{{ page["title"] }}</h2>

TIP: All items in a page dictionary are exposed as attributes, i.e.
page["foobar"] is identical to page.foobar. Dictionary access is useful if
an item may not be set, e.g.: page.get("foobar", "...").

Setting page attributes

Page attributes can be set at the top of a page's source file, in Python's
configuration file style
. They are delimited from the page's content
by a line with 3 or more dashes.


title: Hot News
foobar: King Kong
Here are some news about {{ page.foobar }}.
Did I say {% print(page.foobar) %}?

That way you can also set a page's title explicitly, instead of using the file
name. Other useful attributes to set are description and keywords, which
get used by the default page.html file to set HTML meta tags. Here it comes
in handy to set default page attributes in the macros.py file:


page = { "description": "some stuff", "keywords": "stuff" }

That way you can safely use the description and keywords attributes without
bothering if they are really defined in every page.

Accessing page objects in the macros module

The objects pages and page are also available within macros.py. That
means you can define them as dummys and reference them in macros.py. Poole
updates them when loading the macros module.


page = {} # you can also set defaults here, see previous section
pages = []

def something():
    # when executing this, the page and pages objects above are up-to-date
    print page["title"]

Options and paths

Similarly to page and pages the following objects are available within
embedded Python code and within the macros module:

  • options: The command line arguments given to Poole as parsed by
    Python's optparse module. For instance the base URL can be
    retrieved by options.base_url.
  • project: Path to the project's root directory.
  • input: Path to the project's input directory.
  • output: Path to the project's output directory.

Character encodings

In case you use non-ASCII characters, check the encoding options of Poole. In
most cases working with non-ASCII strings should work straight forward if the
options are set properly (default is UTF-8).

However, be aware that page variables defined within page source files and
derived from a page's file name internally are handled as Python unicode
objects. That means if you want to refer to non-ASCII page variable names and
values form within embedded Python code or from macros.py, make sure to use
unicode strings to reference them.

Custom file converters

If you use LESS or CleverCSS you'll be happy about the possibility to
define custom converters Poole applies to selected files in its building
process. Custom converters may be defined in macros.py using a dictionary
named 'converter' with file name patterns as keys and a converter function as
well as a target file name extension as values:

converter = {
    r'\.ccss': (ccss_to_css, 'css'),

The converter function ccss_to_css must accept the source file name and the
destination file name as arguments. The destination file name is a suggestion
(the source filename mapped to the project's output directory with the
extension given in the converter dictionary) - you are free to choose another

import clevercss

def ccss_to_css(src, dst):
    # when `src` is '/path/to/project/input/foo.ccss'
    # then `dst` is '/path/to/project/output/foo.css'
    ccss = open(src).read()
    css = clevercss.convert(ccss)
    open(dst, 'w').write(css)

Pre- and post-convert hooks

All pages converted by Poole may be processed by custom code in macros.py
using hook functions. In particular, any function whose name starts with
hook_preconvert_ is run after source markdown files have been parsed but
not yet converted. Similarly, any function whose name starts with
hook_postconvert_ is run after the content of pages has been converted to
HTML (but still without the skeleton HTML given in the project's page.html

Pre-convert hooks are useful to preprocess the markdown source and/or to
generate new virtual pages based on existing real pages:

def hook_preconvert_foo():
    # important: replace all foos by bars in every page
    for p in pages:
        p.source = p.source.replace("foo", "bar")
    # create a new virtual page which still has a foo
    p = Page("foo.md", virtual="The only page with a *foo*.", title="Foony")

Virtual pages can be created by providing a virtual source filename relative
to the project's input folder and corresponding markdown content. Page
attributes (e.g. title) may be given as additional keyword arguments but
may also be encoded in the markdown source as in real markdown input files.

A common use case for post-convert hooks is to generate full content RSS feeds:

def hook_postconvert_rss():
    # this is kind of pseudo code
    rss = ...
    for p in pages:
        rss.add_item(..., r.html)

More practical and detailed usage examples of hooks and virtual pages can be
found in the recipes.


You can do some pretty fancy and useful things with inlined Python code and
the macros module, for instance generate a list of blog posts or create an RSS
file. Check out the example recipes.
