FW: Ominous quietude

Ruby

Dear Sirs and Mesdames:

Yesterday I executed the Windows Quick Install of Ruby’s release 18.
4.17rc2. I’m running Windows XP.

When I initiate Ruby’s interactive application (c:\ruby\bin\ruby.exe) it
seems strangely inert. No prompt appears on the opened window (exact
reproduction below). I believe the commands I tendered comport with the
languages’ rules of composition, but they remain, alas, unrequited. If
any among you have a suggestion, I shall remain,

Gratefully yours,

Fred Allen

Hi,

Yiu have started the ruyb interpreter itsself.
Try to find and execute irb.exe (guessed,…I am working on a UNIX
system, where there are no “*.exe”…they are name – for example –
simply “ruby” instead of “ruby.exe” – therefore I think, that “irb”
on UNIX must be “irb.exe” under windows.).

irb is the “interactive ruby shell”.

ruby.exe (“ruby” on UNIX) is the interpreter which process textfiles
with commands.

Hope I could help a little.
Dont hesitate to ask because who who do not ask will get no answers

Keep hacking!

Hi,

For interactive ruby, try “irb” instead of ruby.exe.

ruby.exe invoked with no parameters reads a script from stdin
(standard input) and will execute it when end-of-file is
reached. (On windows, you can use control-Z to type and
end-of-file character.)

But for an interactive ruby session, try irb.

Hope this helps,

Bill
