Problems with first gem using Rake/Hoe

Jim Clark

1/12/2008 12:02:00 AM

Hi,

I'm trying to package my first gem using Hoe (1.4.0) and am having
difficulties with Rake (0.8.1) on a Windows XP system. What I notice is
that when I execute the task through Rake, it will fail yet I can
execute the task outside of Rake. For instance:

C:\rubylogparser>rake install_gem
(in C:/rubylogparser)
zip -r rubylogparser-0.1.0.zip rubylogparser-0.1.0
Successfully built RubyGem
Name: rubylogparser
Version: 0.1.0
File: rubylogparser-0.1.0.gem
gem install pkg/*.gem
rake aborted!
Command failed with status (0): [gem install pkg/*.gem...]

(See full trace by running task with --trace)

Using Google, I see that I am not the only one who has seen these errors
in various incarnations. Does anyone understand why Rake fails when the
tasks succeed otherwise?

Thanks in advance,
Jim

The problem is related to system() and ruby.

It don't take as valid "executables" the batch files (.bat or .cmd)
that ruby on Windows need to get gem, rake, or other gem installed
tools run.

Try the following in a IRB session:
irb(main):005:0> system "gem", "-v"
=> false
irb(main):006:0> system "gem.bat", "-v"
0.9.4
=> true

I you take a closer look, you see that I needed to provide the file
extension to get it working.
Hoe task lack the extension of the command, mostly because it need to
be cross-platform compatible, and is just Windows that needs it.

You can suggest a patch to Hoe project that takes RUBY_PLATFORM in
consideration and set the correct system call.

OK, I see this in IRB too. I'm still a little confused just because the
tasks that Rake is failing on I am typing in exactly as Rake is issuing
them (well, I haven't traced it inside a debugger but based on the
--trace output to the screen).

Case in point, Rake fails on the "rake install_gem" command on the "gem
install pkg/*.gem" yet this works verbatim on the command line. I don't
need "gem.bat install..." on the command line.

Obviously I do need to trace this inside a debugger and understand it
better before I suggest a patch. Being my first gem, I am in that grey
area where when things go wrong, I'm not sure whether it is how I have
things configured or other sometimes Windows specific issues.

Thanks for the help.

Jim

There isn't too much for you to get confused.

Hoe is creating a series of Rake tasks that do system calls. The way
#system method works in Ruby is that unless it is a executable (.exe)
you need the extension for the file, so you need pass the .bat or .cmd
to it.

The verbatim copy of the commandline works in the Command Prompt
because the execution is done by the cmd.exe and not by ruby.

Again, is a known problem of Ruby #system method.

No need for a debugger. If you take a look inside lib/hoe.rb (part of
Hoe gem) you will find the exact code that creates the install_gem
task.

Is nothing related on how you have things configured, is a known
problem of Ruby #system method on Windows.
