I told you: it is a method of capistrano.
set sets the value, fetch gets it
Follow my first link and read the chapter "Variables" ...
Or look here
https://github.com/capistrano/capistrano/wiki/2.x-DSL-Configuration-Variables-Fetch
Or look here
https://github.com/capistrano/capistrano/blob/master/lib/capistrano/configuration/variables.rb

Thanks , you're right, :db_file is defined, and the line runs well...
my concern was about the 'fetch' function which returns a string..
it seems to return the second string argument if the first is not
defined ...
but is it a Ruby function or a Rails function ....
I know a anArray.fetch( aString) but not this one ....

Is this part of a capistrano script?
<https://github.com/capistrano/capistrano/wiki/2.x-DSL-Configuration-V...>If
so then it uses the value in deploy.rb where
set :db_file
is defined.
(Perhaps look
here:https://github.com/leehambley/capistrano-handbook/blob/master/index.m...
)
Otherwise I would imply you should give some more information about the
type of script you are looking at.

I am looking at a ruby script and testing it...
I don't fully understand the following line of code :
database = YAML::load_file("config/#{fetch(:db_file,
'database.yml')}")
=> fetch(:db_file, 'database.yml') ... what's is this function
fetch() ?
I know the fetch(key, *extras) in ActiveSupport, but this is not the
case.... any suggestion ?
thanks
