The goto module was an April Fools joke, published on 1st April 2004. Yes, it works, but its a joke nevertheless. Please dont use it in real codeDo you want to release a Python script, library, framework, or application Excellent. The world needs more Python code. Python 3 comes with a packaging framework called Distutils. Distutils is many things a build tool for you, an installation tool for your users, a package metadata format for search engines, and more. It integrates with the Python Package Index Py. PI, a central repository for open source Python libraries. All of these facets of Distutils center around the setup script, traditionally called setup. In fact, youve already seen several Distutils setup scripts in this book. You used Distutils to install httplib. HTTP Web Services and again to install chardet in Case Study Porting chardet to Python 3. In this chapter, youll learn how the setup scripts for chardet and httplib. Python software. chardet and httplib. Python libraries under any particular license. The process described in this chapter will work for any Python software, regardless of license. Releasing your first Python package is a daunting process. Releasing your second one is a little easier. Distutils tries to automate as much of it as possible, but there are some things you simply must do yourself. To start packaging your Python software, you need to get your files and directories in order. The httplib. 2 directory looks like this. The chardet directory looks slightly different. Like httplib. 2, its a multi file module, so theres a chardet directory within the chardet root directory. In addition to the README. HTML formatted documentation in the docs directory. The docs directory contains several. This will be important later. Also, in keeping with the convention for LGPL licensed software, it has a separate file called COPYING. LGPL. The Distutils setup script is a Python script. In theory, it can do anything Python can do. In practice, it should do as little as possible, in as standard a way as possible. Setup scripts should be boring. The more exotic your installation process is, the more exotic your bug reports will be. This imports the setup function, which is the main entry point into Distutils. Distutils setup scripts consist of a single call to setup and nothing else. I totally just made up that statistic, but if your Distutils setup script is doing more than calling the Distutils setup function, you should have a good reason. Do you have a good reason I didnt think so. The setup function can take dozens of parameters. For the sanity of everyone involved, you must use named arguments for every parameter. This is not merely a convention its a hard requirement. Your setup script will crash if you try to call the setup function with non named arguments. Although not required, I recommend that you also include the following in your setup script. Now lets look at the chardet setup script. It has all of these required and recommended parameters, plus one I havent mentioned yet packages. The packages parameter highlights an unfortunate vocabulary overlap in the distribution process. Weve been talking about the package as the thing youre building and potentially listing in The Python Package Index. But thats not what this packages parameter refers to. It refers to the fact that the chardet module is a multi file module, sometimes known as a package. The packages parameter tells Distutils to include the chardet directory, its init. Thats kind of important all this happy talk about documentation and metadata is irrelevant if you forget to include the actual code The Python Package Index Py. PI contains thousands of Python libraries. Proper classification metadata will allow people to find yours more easily. Py. PI lets you browse packages by classifier. You can even select multiple classifiers to narrow your search. Classifiers are not invisible metadata that you can just ignore To classify your software, pass a classifiers parameter to the Distutils setup function. The classifiers parameter is a list of strings. These strings are not freeform. All classifier strings should come from this list on Py. PI. Classifiers are optional. You can write a Distutils setup script without any classifiers at all. Dont do that. You should always include at least these classifiers. By way of example, here are the classifiers for Django, a production ready, cross platform, BSD licensed web application framework that runs on your web server. Django is not yet compatible with Python 3, so the Programming Language Python 3 classifier is not listed. Here are the classifiers for chardet, the character encoding detection library covered in Case Study Porting chardet to Python 3. Python 3 compatible, LGPL licensed, and intended for developers to integrate into their own products. And here are the classifiers for httplib. HTTP Web Services chapter. MIT licensed, and intended for Python developers. That will cover all the files in the httplib. But for the chardet project, we also want to include the COPYING. HTML files. To tell Distutils to include these additional files and directories when it builds the chardet release package, you need a manifest file. A manifest file is a text file called MANIFEST. Place it in the projects root directory, next to README. Manifest files are not Python scripts they are text files that contain a series of commands in a Distutils defined format. Manifest commands allow you to include or exclude specific files and directories. All manifest commands preserve the directory structure that you set up in your project directory. That recursive include command is not going to put a bunch of. Its going to maintain the existing docs directory structure, but only include those files inside that directory that match the given wildcards. I didnt mention it earlier, but the chardet documentation is actually written in XML and converted to HTML by a separate script. I dont want to include the XML files in the release package, just the HTML and the images. To reiterate you only need to create a manifest file if you want to include files that Distutils doesnt include by default. If you do need a manifest file, it should only include the files and directories that Distutils wouldnt otherwise find on its own. Theres a lot to keep track of. Distutils comes with a built in validation command that checks that all the required metadata is present in your setup script. For example, if you forget to include the version parameter, Distutils will remind you. Once you include a version parameter and all the other required bits of metadata, the check command will look like this. Distutils supports building multiple types of release packages. At a minimum, you should build a source distribution that contains your source code, your Distutils setup script, your read me file, and whatever additional files you want to include. To build a source distribution, pass the sdist command to your Distutils setup script. In my opinion, every Python library deserves a graphical installer for Windows users. Its easy to make even if you dont run Windows yourself, and Windows users appreciate it. Distutils can help you build installable packages for Linux users. In my opinion, this probably isnt worth your time. If you want your software distributed for Linux, your time would be better spent working with community members who specialize in packaging software for major Linux distributions. For example, my chardet library is in the Debian GNULinux repositories and therefore in the Ubuntu repositories as well. I had nothing to do with this the packages just showed up there one day. The Debian community has their own policies for packaging Python libraries, and the Debian python chardet package is designed to follow these conventions. And since the package lives in Debians repositories, Debian users will receive security updates andor new versions, depending on the system wide settings theyve chosen to manage their own computers.
