Import migration from Jekyll to Hugo.
All the posts were converted, and the layout is created. This looks like
it works just fine.

The default tool adopted by the community to manage projects is [leiningen](http://leiningen.org). For those of you who don't know what `lein` is, it's a tool to automate your Clojure project: it will boostrap a new project, install the dependencies, and there's a plugin mechanism to extend the default possibilities of the tool. + +One of the nice feature of the tool is the **checkouts** directory. From the [FAQ](https://github.com/technomancy/leiningen/blob/preview/doc/FAQ.md): + +> If you create a directory named checkouts in your project root and symlink some other project roots into it, Leiningen will allow you to hack on them in parallel. + +For Python projects at [$work](http://www.saymedia.com/careers) I use [virtualenvwrapper](http://virtualenvwrapper.readthedocs.org/en/latest/) to easily work on them without having to deal with conflicting dependencies. When I need to change a library that is used by one of the project, usually I go to the virtualenv directory and create a symlink so it uses the one I'm editing. + +What I really want is a mechanism similar to `lein`, where I can have a **checkouts/** directory inside the main project, where I can clone a library or create a symlink. Since `virtualenvwrapper` provides a hook mechanism, I wrote a small hook inside **~/.virtualenvs/postactivate**: + +```sh +#!/bin/bash + +# move to the directory of the project +proj_name=$(echo $VIRTUAL_ENV|awk -F'/' '{print $NF}') +proj_path=/home/vagrant/src/$proj_name + +cd $proj_path + +if [ -d checkouts ]; then + for ext in $(ls checkouts); do + export PYTHONPATH=proj_path/checkouts/$ext:$PYTHONPATH + done +fi +``` + +Then, when I type `workon $project_name` in my shell, the environment is activated, I'm moved to the right directory, and the library inside the **checkouts/** directory are added to my **PYTHONPATH**. |
