how to

As part of the move of Agaric content from Agaric.com to data.agaric.com, we needed to create a bunch (1,592 to be precise) redirects that look like this one:

RewriteRule ^nice-menus-drop-down-bug http://data.agaric.com/node/1048 [NC,R=301,L]

Stefan, in his wizardry, had already pulled a tab-separated-value file of the old path to the new URL, so that what we had was:

nice-menus-drop-down-bug http://data.agaric.com/node/1048

export PATH=$PATH:/usr/local/share/php/drush

Somehow, in git 1.6, after running git rm -r example to get rid of a directory (called example), it leaves the files there but from then on ignores them. git status lists nothing, ls shows the directory example is still there, and then rm -rf example removes the directory and git status still shows nothing.

You may know about ctrl+shift+R for reverse case-insensitive search (or whatever it stands for) and that is still useful if you remember one very unique keyword from the middle of a command.

Hooks in Drupal are a way of triggering code to run based on naming convention.

This simple and powerful system is a key way in which you or other developers can extend Drupal.

In theory you can put HTML code right into a custom date format declaration. Actually, this did not quite work for some reason... somewhere in class year the code just gave up and pled for mercy.

\<\d\i\v \c\l\a\s\s\="\m"\>M\<\/\d\i\v\>\<\d\i\v \c\l\a\s\s\="\d\y"\>d\<\/\d\i\v\>\<\d\i\v \c\l\a\s\s\="\y\r"\>Y\<\/\d\i\v\>

In order for the cool myprojectname.dev style addresses for sites you are developing locally (rather than 127.0.0.1/myprojectname) from my Mac OS X environment as well as Ubuntu running in a virtual machine, this method uses the IP address available locally that you can find out by typing ifconfig in a shell terminal. It's what follows the text "inet". With luck that is a stable IP address, running in bridged mode (i think) with VMWare Fusion this seems to be working so far. The problem with bridged mode is that it only works with your own internet connection.

Getting a diff (patch-file style display of changes) from a your most recent commit is useful when you commit and it lists three lines changing in a file instead of one. Of course, you should have run git diff --cached before git commit -m "I know what I'm doing.", but when you haven't, or have another reason to take one step back in the history of your work, here is the command that saves looking up the git commit hash.

git diff HEAD^ HEAD

To theme a panels layout you simply copy a .tpl.php file from modules/panels/plugin/layouts/[tempate_name]/panels-[template-name].tpl.php
to your theme directory (or any subdirectory of your theme directory.

Note that the CSS file is not overridable the same way.

A normal (node) page triggers the Drupal-integrated Boost cache to expire and replace the page whenever you edit it. Editing a view unfortunately does not have such triggers. In this case the views are attached to a node, so simply resaving the node rebuilds the cache.

In most cases the view itself will not be modified, rather, you will add or edit a node associated with a view which also refreshes the cache for that views pages. (Note this takes a bit of processing to look up, and i don't think it will apply for blocks.)
