SYNOPSIS
use Config::Frontend;
use Config::Frontend::String;
open my $in,"<conf.cfg";
my $string=<$in>;
close $in;
my $cfg=new Conf(new Config::Frontend::String(\$string))
print $cfg->get("config item 1");
$cfg->set("config item 1","Hi There!");
$cfg->set("cfg2","config 2");
$cfg->del("config item 1");
open my $out,">conf.cfg";
print $out $string;
close $out;
ABSTRACT
This module can be used to put configuration items in. It's build up by using a backend and an interface. The interface is through the Config::Frontend
module. A Config::Frontend
object is instantiated with a backend.
DESCRIPTION
new(backend) --> Conf
Should be called with a pre-instantiated backend. Returns a Config::Frontend
object.
set(var,val) --> void
Sets a variable with value val in the backend.
get(var [, default]) --> string
Returns the value for var as stored in the backend. Returns undef
, if var does not exist in the backend and default
has not been given. Otherwise, returns default
, if var does not exist in the backend.
del(var) --> void
Deletes a variable from the backend. All properties for the variable are also removed.
exists(var) --> boolean
Returns true, if var
exists. Returns false, otherwise.
set_prop(var,prop,val) --> void
Sets property prop
for variable var
to value val
.
set_prop(var,prop,val) --> void
Sets property prop
for variable var
to value val
.
get_prop(var,prop [,default]) --> string
Returns property prop
for variable var
, or undef
cq. default
if the property doesn't exist.
del_prop(var,prop) --> void
Deletes property prop
for variable var
.
exists_prop(var,prop) --> boolean
Returns true if property prop
exists for variable var
. False, otherwise.
variables() --> list of stored variables
Returns a list all variables (not properties) stored in the backend.
properties(var) --> list of stored properties
Returns a list of all properties for a variable in the backend.
cache(cache_on) --> void
If cache_on
= true, this will turn on caching for the get()
method. If caching is on, the get() method will only go to the backend if a variable does not exist in it's cache. The set()
function will delete a variable from cache if it is updated. The del()
function will delete a variable from cache.
clear_cache() --> void
Clears the cache.
