Hi Sil,
The syntax for an array and a list is not the same, hence the problem.
The @ is only for list, to pass an array, you only pass its name (with
the context) as a parameter, and then you use its name to get the
values, as in the following code.
bundle agent pip_example
{
vars:
any::
#
# Define the packages to install/delete
#
"pkgadd[yolk]" string => "0.4.3";
methods:
"any" usebundle => pip_install_pkg("pip_example.pkgadd");
}
### pip_lib.cf ###
bundle agent pip_install_pkg(pkgs_array)
{
vars:
any::
"pip_install" slist => getindices("$(pkgs_array)");
Regards
Nicolas
