Intro

What is Quickly?

• https://wiki.ubuntu.com/Quickly

• Application templating system
• Boiler plate
• Commands
• Integration with infrastructure
• Opinionated choices
• shell completion
• Easy and fun

Quickly in Karmic

• 0.2.5
• First iteration of quickly and ubuntu-project template
• Only one template
• PPA support is there, but a bit brittle
• $quickly tutorial up to date

Quickly in Lucid

• 0.4.0
• Second iteration with 2 or 3 templates
• ubuntu-application, ubuntu-cli, maybe ubuntu-arcade
• $quickly tutorial not up to date yet

Installing Quickly

• $sudo apt-get install quickly
• Lots of dependencies, so a slightly large download
• Sets up lots of useful tools

Creating your app

• 0.2.5: quickly create ubuntu-project appname
• 0.4: * quickly create ubuntu-application appname
• Creates a working application

naming

• In 0.2.5/karmic, only support for one work names
• In 0.4.0/Lucid, support for multi-work names

Editing the UI

• Code files and glade files linked by naming
• automatially hooked up for you

Glade Command

• within project directory
• 0.2.5 $quickly glade
• 0.4.0 $quickly design (support non-gnome templates)
• Must use this command, project won't work otherwise

Glade Tips and Tricks

• Fill tool-like interacton
• Selecting in the inspector
• layout via boxes, VBoxes and HBoxes
• Changing position in a Box
• pack_start, pack_end
• Fill and expand control sizing, auto layout on window resizing
• Border and padding control spacing
• Use stock items when possible
• add dialogs with the "dialog" command
  • 0.2.5: $quickly dialog dialogname
  • .4: $quickly add dialog dialogname
  • import the dialog
  • use New*Dialog()

d = New*Dialog() response = d.run() if response == gtk.RESPONSE_OK:

• #do your stuff

Signals

• In glade on signal tab
• for buttons, use both clicked and activated
• for menus, just activated
• writing signal handlers

def handlername(self, widget, data=None):

• #do your stuff #widget is the sender

Writing Code

• finish_inishializing versus init()

Debugging and Testing

print statements

• most common and easiest
• leaves print statements in code, need to be deleted

Logging

• won't cause debug output to be printed in normal run
• a bit broken at the moment

debugger

• pdb is a command line debugger, works well, but is a bit hard to use
• there are graphical debuggers built into some IDEs

Packaging

• For sharing apps via email, or dropping a file somewhere
• quite forgiving

setting up your app for packaging

• add your name and email to the copyright file
• issue license command
• Edit *.desktop.in to define category
• add author, email, description, long description to setup.py
• $quickly package

Creating a deb

• $quickly package
• try it out

PPAs

• a bit less forgiving than package
• create ssh keys as per launchpad instructions (will need for release)
• create pgp keys as per launchpad instructions
  • Don't use a comment!
  • set DEBEMAIL and DEBFULLNAME in .bashrc, the same as what was in your gpg key
  • match gpg --list-secret-keys

export DEBEMAIL=rick.spencer@canonical.com export DEBFULLNAME=Rick Spencer

• Create a PPA
  • for 0.2.5 call it only "ppa", nothing else will work
  • 0.4.0 will allow you to choose a ppa
• To release, you need to create a project in launchpad
• $quickly share - puts latest in your ppa
• $quickly release - does the same but also increments version and makes an announcement
