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.

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.

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?
