Lion dev environment notes

gistfile1.md

First things first...

• Swap Control and Caps Lock in System Preferences -> Keyboard -> Modifier Keys
• Google Chrome http://www.google.com/chrome/
• iTerm2 http://www.iterm2.com/
• Oh my zsh https://github.com/robbyrussell/oh-my-zsh/
• XCode (from the mac app store)
• XCode command line tools (run XCode, go to Preferences -> Downloads -> Command Line Tools)
• Homebrew https://github.com/mxcl/homebrew/wiki/installation

Fire up your database

• Edit /etc/paths to put /usr/local/bin on top, so that lion's psql doesnt win

Install postgres and init the db

brew install postgres
initdb /usr/local/var/postgres

Add aliases to your shell for spinning postgres up/down (and while we're at it, put brew's python packages on the path so we can run mapnik later and tell zsh not to autocorrect a couple things)

alias postgresup='pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start'
alias postgresdown='pg_ctl -D /usr/local/var/postgres stop -s -m fast'
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH
alias mvim='nocorrect mvim'
alias rbenv='nocorrect rbenv'

Okay, now install the GIS fun after postgres is happy

brew install gdal --with-postgres
brew install postgis

(creating geo databases got easier, no need to install the templates, see http://postgis.refractions.net/documentation/manual-2.0/postgis_installation.html#create_new_db_extensions)

Higher-level GIS tools

Tap the homebrew/science repo and build QGIS

brew install libspatialite
brew tap homebrew/science
brew install qgis --with-grass --with-postgis

Follow the instructions to make it a pretty bundle...

Build mapnik

brew install mapnik

And of course, you must have virtualenv

Get pip, if you haven't already, then vitrualenv. And then virtualenvwrapper (http://virtualenvwrapper.readthedocs.org/) cuz its awesome. (Adding the setup to the end of my .zshrc, use .bash_profile or whatever if you like.)

sudo easy_install pip
sudo pip install virtualenv
sudo pip install virtualenvwrapper
echo 'source /usr/local/bin/virtualenvwrapper.sh' >> ~/.zshrc

Doing ruby?

Get rbenv (https://github.com/sstephenson/rbenv).

Note, I'm modifying my .zshrc cuz I do zsh. You'd do your .bash_profile if you're normal.

brew install rbenv
brew install ruby-build
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(rbenv init -)"' >> ~/.zshrc

You'll want to open a new shell to get that stuff we just put on your path. Here's how you see what fancy new ruby versions you can install, and how to get one w/ rbenv:

rbenv install
rbenv install 1.9.3-p194

Other tools I love

• TileMill http://mapbox.com/tilemill/
• macvim (Trying vim. We'll see how this goes.) http://code.google.com/p/macvim/
• iStat Menus http://bjango.com/mac/istatmenus/
• The Unarchiver http://wakaba.c3.cx/s/apps/unarchiver
• CrashPlan http://www.crashplan.com/
• Divvy http://mizage.com/
• BusySync http://www.busymac.com/busysync/ (Not necessary for dev, but necessary for keeping Google Calendar and Exchange in sync.)
• Skype (direct download link) http://www.skype.com/intl/en-us/get-skype/on-your-computer/macosx/post-download/

I mapped F2 to remove trailing whitespace for every line. With PEP8 checking, extra whitespace leads to glaring red blocks, and instead of turning off that warning I abide by the rules.

" Remove trailing whitespace from every line
nnoremap <silent> <F2> :%s/\s\+$//e<CR>

Since I'm often frantically mashing Escape or F2, I remapped F1 to do nothing (who needs a dedicated key to bring up embedded help?).

" damn you, F1! I'm just flailing to hit Escape, I don't want help!
nnoremap <F1> <nop>

Also, if you're masochistic, you can force yourself to use the standard dired movement in vim using HJKL by remapping the arrow keys to do nothing.

" Remap the arrow keys to nothing to force me to use hjkl for movement
noremap <Up> <Nop>
noremap <Down> <Nop>
noremap <Left> <Nop>
noremap <Right> <Nop>
