while cond do indentation detection is off #158Description
Description
IRB attempts to detect the correct indentation level based on keywords (while, until, for, do, etc.) and some keywords can occur on the same line. For instance (while cond do) needs to only be indented once instead of twice. This is handled here https://github.com/ruby/ruby/blob/06b44f819eb7b5ede1ff69cecb25682b56a1d60c/lib/irb/ruby-lex.rb#L362-L365
However, there are cases that accidentally trigger this code and do not provide correct indentation. Consider this method:
def yield_if(block)
yield if block.call
endIt can be called like this:
yield_if ->{true} do
puts "bad indent"
endBut if you try to type that in it will be forced to:
yield_if ->{true} do
puts "bad indent"
endResult of irb_info
Here is a video of the indentation behavior:
