ruby if string contains -


with following code, expect bravo if file name 123456.txt.

if file_name#=~ ('.+(775|776|777|778)\.txt')   @outputs['answer'] = 'alpha' elsif file_name#=~ (.+(456|546)\.txt)   @outputs['answer'] = 'bravo'

but answer results in alpha. missing here?

# defines start of comment. operator test against regexes =~, not #=~.

if file_name

will case being picked, unless file_name false or nil, hence why 'alpha'.

also literal syntax create regexes //, not (''):

if file_name =~ /.+(775|776|777|778)\.txt/
