Feature #14386
Updated by k0kubun (Takashi Kokubun) about 2 years ago
I sometimes write code like:
~~~ ruby
system('git pull origin master') || raise('Failed to execute: git pull origin master')
system('bundle check || bundle install') || raise('Failed to execute: bundle check || bundle install')
~~~
Using rake, we can simplify the above code to the following one, but there's no way to do that outside Rakefile. (Note that I just want to do the same thing as "bash -e", the error message is actually not important.)
~~~ ruby
sh 'git pull origin master'
sh 'bundle check || bundle install'
~~~
If we add the following option, we can simplify such code even when we're not on a rake task. I'm not sure whether it's a good name or not though.
~~~ ruby
system 'git pull origin master', exception: assert_status: true
system 'bundle check || bundle install', exception: assert_status: true
# => RuntimeError: Command failed with status (1): bundle check || bundle install
~~~
