I have a script. When I run it via "ruby myscript.rb", it works great.
When I run it via "./myscript.rb", it complains:
: No such file or directory.
The top of the file starts with "#!/usr/bin/env ruby", which works for
other scripts in the same directory. I know it's spelled right. And the
file is set executable.
The colon (":") at the start of the error message makes me think it's
looking for a file with no name when it should be looking for my script.
Again, the script works great when run as a param to the "ruby..."
command.

- 1. RubyCocoa and DarwinPorts Ruby?
Can anyone point me to potential problems with setting up a RubyCocoa Framework if Ruby has been installed with DarwinPorts and thus resides in /opt/local? All comments welcome john - 2. Support for audio recording and analysis using Ruby?
Hello, I was wondering if there were any modules available for Ruby to capture and analyze audio that runs on Linux. I'd like to capture short snippets of audio (0.5 to 1 second) and then do an FFT. Thanks, Wink Saville - 3. Q: How to initialize debugger's state when starting
Quick question: When starting a Ruby script in debug ('-rdebug') mode, what's the simplest way to source an *rc-type file for, say, setting breakpoints? Is it possible to do such during the invocation of `ruby` at the command-line? Thanks, --J J-S - 4. Bug in Ripper
Hi, Minero Aoki has confirmed that the following is a bug. I'm not (yet!) sufficinetly familiar with the Ruby internals to have a go at fixing it though :(. Any ideas? - perhaps a patch or even a hint of where to look in parse.y would help. Essentially Ripper treats the input: ='foo as an op (the =), followed by a tstring_beg (the ') and a tstring_end (foo). It should treat foo as a tstring_content. [I understand that this isn't valid ruby code, but it's not great given the expected use of Ripper to parse incomplete code (e.g. Autocompletion)]. Sample code can be found at the bottom of this post. Cheers, Jon require 'ripper/filter' class JonsFilter < Ripper::Filter def initialize(str) super str Ripper.private_instance_methods.grep(/^on_/).each { |n| m=n.to_s eval(" def " + m + "(tok, f) puts '<" + m[3..m.length-1] + ">' + escape(tok) + '</" + m[3..m.length-1] + ">' end ") } end ESC = {'&' => '&', '<' => '<', '>' => '>' } def escape(str) tbl = ESC str.gsub(/[&<>]/) {|ch| tbl[ch] } end end $input="='foo" JonsFilter.new($input).parse($stdout)

Did you "chmod +x" the script?

Sorry. I just noticed that it is already executable. What if you use the path straight to the ruby interpreter, and not /usr/bin/env?

wtf? There isn't any whitespace or blank lines before: #!/usr/bin/ruby is there?

Whenever I get weird messages like this it always turns out to be a problem with line endings. By any chance did you last save the file on a Windows system?

Your script has been on a Windows box or otherwise polluted with a \r (Carriage return) after ruby? The kernel can't find /usr/bin/ruby\r -jonathan

> Your script has been on a Windows box or otherwise polluted with a \r That's it, that's the one. I had this problem with another script the other day. It "went away" after I did a whole bunch of stuff. This must've been it. 2006, and we're still dealing with line endings :-) How do I convert it? -- Posted via http://www.**--****.com/
