Found it the hard way.
Improper/misleading:
true or true ? "yes" : "no"
=> truethe above is basically the same as this:
true or (true ? "yes" : "no")
=> trueThe proper way:
true || true ? "yes" : "no"
=> "yes"Month: October 2011
Tell bundler to install gems globally when using capistrano
Seems like it’s not so straightforward. Here’s the excerpt from my config/deploy.rb:
require "bundler/capistrano"
set :bundle_dir, "" # install into "system" gems
set :bundle_flags, "--quiet" # no verbose output
set :bundle_without, [] # bundle all gems (even dev & test)Maybe someone finds it helpful.
Painful ruby 1.9.2-p180 to 1.9.2-p290 upgrade
I did the recommended upgrade of my current p180 to the new p290 using rvm:
$ rvm upgrade ruby-1.9.2-p180 ruby-1.9.2-p290First annoyance – moving gems from one gemset to the new one took over 40 minutes. Have really no idea why.
But after it was done, whenever I tried to run ‘gem’ or ‘rake’ or ‘bundle’ I got:
Invalid gemspec in [/home/jkl/.rvm/gems/ruby-1.9.2-p290/specifications/guard-0.8.1.gemspec]: invalid date format in specification: "2011-09-29

...
and so on...The above is another manifestation of the YAML engine switch from Syck to Psych and all of the incompatibilities it has brought. The problem is that now you have to reinstall all of your gems, because all installed gems have wrong gemspec specification. D’oh.
I fixed it by running:
$ rvm gemset emptyAnd then bundling in each project…
$ bundle
