Woah, that's a long title.
So, just wanted to share the little shell script I use for setting up local development sites in a one-liner in the terminal. Be advised that I don't usually write shell scripts, so if you are a pro, and I have made some obvious mistakes, please feel free to give improvements in the comment section. Also, while i have been writing this post, i noticed that Klausi also has a kick ass tutorial and shell script on his blog. Be sure to read that as well, since the article is much more thorough than mine. But since my script is for those even more lazy, I decided to post it anyway.
The idea I had was pretty simple. I constantly have the need to set up a fresh, working copy of drupal in various versions with various modules, i.e for bug testing, prototyping, or just testing a patch on a fresh install. While drush make and installation profiles are both awesome tools for a lot of things, I wanted to install Drupal without making make files and writing .info files, and at the same time generate the virtual host and edit my hosts file. And why not also download and enable the modules i need. For a while I used just

$ drush si

(site-install) on a specified directory for flushing and starting over, but part since I have little experience in writing shell scripts (I said that, right?), I thought, what the hey, let's give that a go. Fun to learn new stuff.
On my computer the script is called vhost, but since this is not a describing name, and the script is all about being lazy, let's call it lazy-d for the rest of the article (lazy-d for lazy drupal. Also, it is kind of catchy).

A lot of different people has started experimenting with Phonegap and Drupal. You have Jeff Linwood and his Drupal plugin for Phonegap for iOS, and I just discovered Drupalgap as I was planning this post the last weeks, which does more or less (actually it does more, but not all) some of the same things I will try to do in this post.

If you want to get up and running real quick, Drupalgap seems great. If you want to learn the code behind it, and extend it yourself (this was my motivation), keep reading.

Cloning a production site to your local development environment is super easy. Often you have it in git, or maybe even as a make file. Anyway, you just grab the code and restore the site from a backup_migrate dump. But maybe you have a KING SIZE files directory that you don’t want (or have the time) to download. Enter Apache rewrite magic!

So, today i decided to have a go at the services module, to make an app post nodes to my site. With services module enabled you can do a number of things from non-drupal sites, for example you can post nodes through your phonegap app by javascript. And that is exactly what i wanted to do today.

So you have a feed that you aggregate through feeds, and all new items should have the same value in a given field. For example if you have feeds from 4 different webshops, you may want to add a fixed value of the webshop description that is not present in the feed for each different feed. So how do you make a feeds feed give the same value for each feed item? If you use feeds x path parser (as I often do), how do you fix a value for each item in the feed? Or more specifically, how do you insert a fixed value with xpath?
