  Emacs and Python

  I use Emacs as a python IDE. The web already offers a significant number of resources on the subject but I've made a couple of specialized tweaks that I feel may be worth sharing. So here we go.

  Why am I doing this? Well, the simple answer is that I like using Emacs. I do most of my writing in it. I use it as my task manager and TODO list. I have, in the past, used it as my email client. So it makes sense that I would use it as my python development environment. Your mileage may vary.

  Coming to Terms With the Nightmare That Is Python Packaging

  I started YAWT a while ago, in python, because a) I wanted to learn a dynamically typed programming language and b) python seemed like a relatively easy, fun, popular, not insensible choice. To be fair, it is a fun language to use.

  At the time, I gave very little thought actually packaging yawt - i.e. making it easy for someone to actually install and use. Mostly, I simply didn't think I'd ever have to do this - yawt was my baby, and I was the only one using it, so why bother?

  Thoughts on Modularizing Flask Applications

  I've been playing around with the Flask web framework for a while now. It's the basis for YAWT, the CMS/blogging system I'm currently developing (mostly as an exercise in familiarizing myself with Python)

  With Flask, it's dead simple to get a very basic web application up and running:

  :::python
  from flask import Flask
  
  app = Flask(__name__)
  
  @app.route("/")
  def hello():
      return "Hello World!"
  
  @app.route("/blah")
  def blah():
      return "Hello Blah!"
  
  if __name__ == "__main__":
      app.run()

  Error Handling in Perl

  Okay, this won't be the most exciting entry in the world. There are several different ways of logging or recording errors and warnings in perl, and I find I easily get confused. So this entry will serve as a very, very basic reference for me. Other people may find it useful. Or not.

  Scoping in Perl

  I just read a very clear tutorial on Perl scoping mechanisms:

  http://perl.plover.com/FAQs/Namespaces.html

  I often get bitten by scoping issues but unfortunately (or fortunately?) it's usually easier in Perl to work around your problem than to understand the reasons behind it.

  One part I found interesting was the section labelled "The Current Package" which explains the use of the package command in Perl. There is a tendency (or, at least, I have a tendency) to conflate the use of the Perl package command and, say, the use of the Java package declaration because they are often used to achieve the same effect, namely the separation of namespaces, and also because, by convention, they are used in a syntactically similar way. Because of this, it is easy to forget that the package command in Perl is just that: a command. You can call it from anywhere, multiple time from the same file even, and the effect is simply to change the current package - which in itself doesn't have a huge effect on how you write your code, just the way to access your variables.
