Unknown regexp options

Ruby
1

When I try to “require”, “load” or use rdoc on a .rb file in IRB I get
the error

“SyntaxError: compile error
(irb):5: unknown regexp options - gary
from (irb):5”

Also, i’m using the preloaded irb on my mac which uses “>>” instead of
“irb(main):002:0>” at the command line. It’d be nice to have that
feature to know if I’m still coding within an object.

I can’t seem to find anything on either problem on the net. Your help is
greatly appreciated!

I don’t have a mac, so I’m guessing. Have you perhaps a .irbrc file in
your
home directory? If so, then maybe that is the cause for both behaviours
you
get. Try running irb with the -f command line option, which disables
reading
the .irbrc file, and see what happens.

Regarding the prompt issue, the >> prompt can be obtained by using the
–simple-prompt command line option, so maybe you can override this
passing
the --prompt-mode default option.

I hope this helps

Thanks for you help Stefano!

I can’t find a .irbrc file, and my mac is set up so hidden files are
shown so that’s not the problem.

Running irb -f does show the “irb(main):001:0>” , so that’s half the
battle!

Still getting the unknown regexp though, even with the -f command.

any ideas?

You need to post your full irb session and the file you are trying to
require/load. The error looks like at some point in your file you must
write:

/ThisIsYourRegExp/gary

Which to Ruby looks like you are trying to give the options ‘gary’ to
the
RegExp. Given the coincidence of your name, I would suggest you have a
simple syntax error in the file you are trying to load.

Can you show exactly what you type, and exactly what response you get?

Also, what do you get from

ENV.select { |k,v| k =~ /RUBY/ }

?

The path of the file should be a string:

load ‘/Users/gary/Desktop/test.rb’

The content of the file is just:

puts “test”

The irb session is:

load /Users/gary/Desktop/test.rb

Try:

load “/Users/gary/Desktop/test.rb”

Otherwise, it looks like a literal regular expression.

The irb session is:

The .rb file was written in textedit with no rich text. I was using
