Can not Rake :), please help

Hi, I dont get what is wrong with this rakefile:

···

#====================================
task :default => :TTList

checkfile = "arrangement0/list.txt"
task :TTList => checkfile do
  regenarate
end
#===================================

So, regenarate function regenarates bunch of files, including the
checkfile. When I call rake, it should run :TTList task, but only if
checkfile is not there. This rakefile runs :TTList even if the
checkfile exists.

thx.

If I recall correctly, it works the other way around. You're defining
the checkfile as a pre-requisite of TTList, so it would only run if
the checkfile was already present. If you remove it, does TTList run?

I think you probably want:

task :default => checkfile

checkfile = "arrangement0/list.txt"
file checkfile do
        regenarate
end

AFAIK tasks are more like functions, dependent on other tasks, which must be
done first. 'file' creates a file task, which will run in order to create
that target (checkfile).
If you want checkfile to be dependant on other files:

file checkfile => [depfile1, depfile2] do
        regenarate
end

For more info, go through the tutorial:

PS: regenerate, not regenarate

thx.
