strip_heredoc()
Instance Public methods
Strips indentation in heredocs.
For example in
1 2 3 4 5 6 7 8 9 | if options[:usage] puts <<-USAGE.strip_heredoc This command does such and such. Supported options are: -h This message ... USAGEend |
the user would see the usage message aligned against the left margin.
Technically, it looks for the least indented line in the whole string, and removes that amount of leading whitespace.
