testing rake

[Raphael Bauduin]

I'm testing rake. I found it promising, but I've got I problem with defining a rule.

I take the example of the website but get an error. Here is what I do:

rb@bidibule:~/test$ rake -V
rake, version 0.3.1

rb@bidibule:~/test$ cat rakefile
rule '.java' => [
proc { |tn| tn.sub(/\.class$/, '.java').sub(/^classes\//, 'src/') }
] do |t|
puts "source = #{t.source}"
end

rb@bidibule:~/test$ rake gf.java
(in /home/rb/test)
rake aborted!
Don't know how to rake gf.java


Shouldn't it print something like
source = gf


Hoping I didn't miss something obvious in the docs ;-)

Thanks.

No, the docs are wrong. There was a typo in the rule. It should state
that the class files are dependent on the source files, not that the
source file is dependent on the source file (duh).

The following works for me ...

JAVASRC = FileList['src/**/*.java']
JAVACLASSES = JAVASRC.gsub(/java$/, 'class').gsub(/^src/, 'classes')

task :default => JAVACLASSES

rule '.class' => [
proc { |tn| tn.sub(/\.class$/, '.java').sub(/^classes\//, 'src/') }
] do |t|
puts "source = #{t.source}, target=#{t.name}"
end

Where did you see that in the docs? I'll correct it.
