Re: Regexp rescue method

I can’t catch it even with rescue Object… wow.

That’s not surprising. Malformed regexps are a parse time error.
is what builds the Annotated Syntax Tree which Ruby runs. No Ruby code
be executed until the AST has been built, i.e. the whole file has been
parsed successfully, and that includes your exception handler of course.

The same applies to other structural errors, such as mismatched
or ‘end’ statements.

If you put the code into another file and load it using ‘require’ or
then you can catch the error:

$ cat a.rb
regexp = /[/
$ cat b.rb
require ‘a’
rescue SyntaxError
puts “Darn.”
$ ruby b.rb
