Split string into equal slices/chunks

Closed 7 years ago.
I was wondering how I could program something to split a string into blocks of five using Ruby. Help much appreciated.
You can use String#scan method to achieve it. E.g 'string_test'.scan(/.{1,5}/)

ENV=${deploy-qa}
echo $ENV
qa
Relatively new to bash and I'm trying to set up a pipeline that switched based off the ending of a string and accidentally stumbled across this. I'm unsure how this actually returns 'qa' though. This is what I was looking to do, but I'd like to understand what's actually happening. I dont understand whats causing the 'deploy-' bit to drop off.

Are you depending on your nested variables?
If not you can try structuring your data using scss lists.

I am working on some code that has paths that look like this:
"pack://application:,,,/FOO.Bar.Baz;component/Gorp/bazzle.xaml"
What do the 3 commas mean, and what is this path referencing?
Typically they are placeholders for parameters that were not supplied. It usually means ... "use the default values" for those parameters.
