For this to work you need to have your Drush aliasses configured

You also need the path to your Browser app.

alias customer_test_dir='cd path-to/customer_dir'
alias customer_test='customertest_dir ; open -a /Applications/Chromium.app `drush @tst uli --mail=clemens@build2be.nl --no-browser`'

cd web/code/

This is a quick sketch / preparation for a particular 'Contributing to Drupal' 2 hours event.

Sprint

To get started you may begin on Organizing sprints (work parties) and its sub pages. Don't bother to much about the term Sprint. We assume you want to focus together on something useful.

Coding style?

Building software is a complex and sometimes tedious process in which you make errors and mistakes. Testing for errors is mostly done by running your website / code through tests either manually or automatically.

Checking for your code style like formatting and documentation flaws you can use a code sniffer. For PHP you can run phpcs using PHP_CodeSniffer.

Drupal core provides core/phpcs.xml.dist to tell phpcs what to test for.

# Sync database
# Fix before receiving files
# Get the files
# Fix after receiving
# Drupal 7 variant of cache-rebuild
# Login to site
# Make sure drush finds the features drush extension
# List features with changes

With the online service http://yuml.me one can draw some UML Diagrams. Wouldn't it be great to build that into Drupal? Checkout the new yUML module.

While working on Deploy RestWS for D7 project issue JSON I needed a pretty print for the node.json and scanner done for Drush Issue Queue Commands Fix for the new json structure on d.o D7. Both issues as still open so help needed.

Doing some research I learned about the PHP context or more specific the HTTP stream context

Who is calling my function so many times? With devel module and some probing using debug_backtrace and a nifty by ref variable it's a snap.

As a followup on A pinch of Symfony for D8MI? why do we need to squash?

After some more squash and push -f attempts regarding pull request for Symfony I get the hang of it.

But chx said in squash is bad as we loose history on the development process.

So how should we do this on d.o when git phase 3 lands? Those discussion seems to got to a halt.
