— Yup - Windows, Linux, Mac, Phones, Pads and Vitas all running the game in here. If you don’t develop all at once, you can end up with a main version and ports. Not good. (via tonyrevdev)

Markdown2 vs Markdown

While working on a style-overhaul. I noticed that portions of our views are generated with markdown2, which as it turns out, produces terrible markup.

Markdown like

###This

Produces HTML like

<h3><p>This</p></h3>

When it ought to be

<h3>This</h3>

This is something that the original python markdown module does as it should. The 2 in markdown 2 is a little misleading; the original markdown module is still being actively maintained.

After the switch, it necessary for me to port over our markdown extensions. Namely, we want some blocks of markdown to open their links in a new tab because they will always refer to external resources. Fortunately markdown has a robust extensions API and the end result looked like so:

# -*- coding: utf-8 -*-

""" Text generation and transformation utilities """

import markdown as md
from markdown.extensions import Extension
from markdown.treeprocessors import Treeprocessor


class NewTabLinksTreeProcessor(Treeprocessor):
    def link_process(self, element):
        """ Traverse the element tree. """
        children = element.getchildren()
        for child in children:
            if child.tag == 'a':
                child.attrib['target'] = '_blank'
            self.link_process(child)

    def run(self, root):
        self.link_process(root)
        return root


class NewTabLinksExtension(Extension):
    """ Makes links open in a new tab. """
    def extendMarkdown(self, md, md_globals):
        md.registerExtension(self)
        md.treeprocessors.add("newtablinks",
                              NewTabLinksTreeProcessor(self), "_end")


def markdown(text):
    """ Return markdown `text` rendered in HTML. """
    return md.markdown(text, [NewTabLinksExtension()])

Bilingual Money Regex

When entering money into a form, there’s all sorts of potential ways a person could want to format the value, especially when you’re trying to serve a bilingual user base. To match every possible format (I could think of) I came up with the following regular expression:

^(\$?\d{1,3}((,\d{3})*|( \d{3})*|\d*)(\.\d{2})?|\d{1,3}((,\d{3})*|( \d{3})*|\d*)(\.\d{2})?\$)$

This matches:

  • Big long numbers: 99999999
  • Leading and trailing dollar signs: $99, 99$
  • Space delimited numbers: 99 999 999$
  • Comma delimited numbers: $99,999,999
  • Cents: $99.99

This DOES NOT match:

  • Improper use of delimters: $9 99, 999 9 etc.
  • Mixed delimters: $99,999 999
  • Mixed dollar signs: $99$

Drop this regex in your validator and enjoy!

Today at Goodwill, I found this:

(sorry for poor image quality, i only had my cell phone available today)

It is a magnificent Model 500 telephone, with only very minor damage, for a princely 3.99. This was a find, as I’d been wanting one of these for some time. What follows is what I did…
