Ruby command line options s and S
404344 [lists@ru y- ] Can anyone help me to understand the difference between s and S with

|   404353 [lists@ru y- ] Thanks @Jamal - but why $RUBYPATH is showing nothing?
|   404367 [sto.mar@we .] Because it's empty or not defined?
|   404368 [lists@ru y- ] Which one is not defined as per your doubt?

|   404386 [me@da id wd ] Dude!

Error is coming with ruby commandline option "-d"
404371 [lists@ru y- ] I was trying to play with -d option in Ruby. But getting the below
404374 [matma.rex@gm] That's simply what -d does  it prints all exceptions that ever happen in your code, even if they are rescued.
404376 [lists@ru y- ] even if they are rescued. <~~~~ Could you explain this line more elaborately?
404381 [sto.mar@we .] could you google "ruby rescue exceptions"?
404393 [lists@ru y- ] Yes I know what is "rescue", rather I asked the explanation - "it prints all exceptions that ever happen in your code, even if they are rescued."
404396 [ryand-ruby@z] Do you realize that you've burned most of your bridges here, right?

Best DRY way to write bang versions of methods?

What are lambda functions used for?

skip iteration in each loop

| 404459 [lists@ru y- ] The output should be in a different array.
+ 404460 [lists@ru y- ] I doubt this is the best method, but here's one way to do it
| 404461 [lists@ru y- ] [].tap do |a|
| 404462 [adam@ap es o] A good rule of thumb when dealing with a "primitive" like an Array: if

[from BASIC to Ruby] so, what's the proper way to replace funcionality of GOTO ?
404491 [lists@ru y- ] I need to make few scripts for tasks I do often manually, but last time
+ 404492 [lists@ru y- ] Yes, It has. You can try "catch - throw" in Ruby's world.
| 404494 [ryan@ra to m] Love U Ruby: I'm really not sure what you meant by that response, but
| 404520 [ryand-ruby@z] You're wrong.
| 404523 [ryan@ra to m] Yeah, I realized that...still doesn't make him right :-)
| 404525 [matma.rex@gm] Actually this makes him pretty much the definition of right.
| 404526 [ryan@ra to m] ...
| + 404527 [matma.rex@gm] When one is implementing a command-line interface like this one, and you don't want to have a dozen of two-line methods, judicious use of throw..catch is a reasonably nice solution.
| | 404531 [tamouse.list] people, people.
| + 404530 [garthy_lmklt] I just wanted to say that I think Ryan is attempting to steer the OP in
+ 404508 [lists@ru y- ] Be careful saying "no one uses BASIC nowdays". I have no doubt there is
| 404512 [lists@ru y- ] Actually I like FreeBASIC, it's cross-platform, syntax I'm somewhat
| 404515 [wishdev@gm i] Baseline - you are certainly free to move to classes or any other concepts
+ 404510 [jw1496@at .c] There is no one way to replace GOTO.  GOTO is at the heart of many structured control structures.  What you need to do is think about what you are trying to do and where you are trying to go when you are done.

Re: so, what's the proper way to replace funcionality of GOTO ?
404495 [lists@ru y- ] before going to challenge other you should "GOOGLE" - here I did for

+ 404498 [lists@ru y- ] OP asked is it there? I have given the reference to him- yes Ruby has. i
+ 404511 [jw1496@at .c] I think GOTO gets a bad rap.  Actually, I find the COMEFROM command far more terrifying.  It's mentioned in the comments...
  + 404516 [lists@ru y- ] Firstly, I know what are Functions/Methods, but I find GOTO much easier
  | 404518 [shortcutter@] Where's the difference?  With a GOSUB the RETURN will also take you to

How do you associate the items of a collection instance with the collection in a smart Ruby way?
