User login

Agaric

Set login name to use for SSH per host

As a completely hypothetical example, suppose you boneheadly thought it would be nice to standardize your local login name to something different than on some existing servers.

You want standard scripts that assume current username to work— you wrote them to share, after all. So how to make this work?

Something like this in your ~/.ssh/config file (create and chmod 600 if it doesn't exist already) will work:

Host agaric-test
Hostname test.example.org
User bmelanco

Troubleshooting ssh connections problem

Micky found this which was key to debugging our connection problem— one way to watch what is happening with the SSH connection attempt is by opening a port just for this use on the server:

sudo /usr/sbin/sshd -d -p 2222

Then from the client:

ssh -vv -p 2222 example.com

Setting up a new GNU/Linux computer (Debian/Ubuntu flavor) for Drupal work, Agaric style

Create an SSH key

ssh-keygen

Send a copy of the public key to an agaric with access to the test server to add it there. Read more about setting up public keys and agent forwarding.

Get Drush

Follow composer instructions on https://github.com/drush-ops/drush (preferred over apt-get or PEAR.)

Adding Git projects to the KGB bot

Stefan set up the kgb-bot to post in the Agaric IRC channel when anyone pushes a commit to one of our repositories. These repositories are hosted on our server, and each one needs to have a very simple bit of configuration added to it and to the KGB server configuration when we add one.

Here's the easiest way for me to do that. For information about getting started with KGB in the first place, see http://www.donarmstrong.com/posts/switching_to_kgb/

move user search tab from search/user to admin/people/search

Agaric decided to make a contributed module to do this: http://drupal.org/project/usersearchtoadmin

See that project page. The below is mostly notes on wrong turns!

It would be nice if this just used a different permission other than a person's ability to access profiles:

Command line Git on Windows

A principal at Agaric regrettably uses Microsoft Windows as a primary operating system. In fact, though, everything works great for him using the open source integrated development environment Eclipse to develop, including using the eGit plugin-- except when something goes wrong, and my (limited) command line knowledge of Git is useless to help him.

Fortunately, it turns out to be pretty easy to have command-line Git on Windows with Eclipse, it just isn't well documented.

Undo Drupal's over-aggressive shortening of user names

And use a real ellipses!

Drupal's theme_username() is used many places within Drupal, and shortens any name over 20 characters, which can be a lot if you encourage people to use full names. This can be undone with a preprocess function in your module or theme, just replace EXAMPLE with your module or theme name.

Maintaining a Drupal project with Git: Vacating the master branch

If you've already been committing code to master, do this to start a new 7.x branch and kill off the code in the master branch so noone gets confused.

cd /path/to/repo
git checkout -b 7.x-1.x

git push origin 7.x-1.x

git checkout master
git rm -r *
echo "Real code is not kept on the master branch, to see the code: git checkout 7.x-1.x" > README.txt
git add README.txt
git commit -m "Add a README explaining that the master branch is empty."
git push origin master

Define and Use a JQuery Plugin as a Helper Function for Drupal JavaScript

Here's the basics of defining and using a JQuery plugin within the context of Drupal.

This is definitely not the best and highest use of a plugin, and may in fact be a downright abomination-- this isn't a plugin that really works outside the context of the code it is written for, and certainly not outside Drupal. But it was a clean way to abstract out 42 lines of code, so here it is, for the enjoyment of all.

The first part here is simply how to call JQuery from Drupal, the second part is the plugin.

How to fetch a file at a URL and set it as the default image in an image field

There's two separate cool things here that you might want to do. One, simply know how to save a file from a URL (there's a secret Drupal function for that in system module) and two, how to give an image field a default image when creating it programmatically (that part is outsourced to the fieldhelp module).
