Config::Find - Find configuration files in the native OS fashion
use Config::Find; my $filename=Config::Find->find; ... my $fn_foo=Config::Find->find( name => 'my_app/foo', mode => 'write', scope => 'user' ); my $fn_bar=Config::Find->find( names => [qw(my_app/bar appbar)] ); my $fh=Config::Find->open( name => 'foo', scope => 'global', mode => 'w' ) my $fn=Config::Find->install( 'original/config/file.conf', name => 'foo' ); my $fn=Config::Find->find( file => $opt_c, name => foo );
Config::Find searches for configuration files using OS dependant heuristics.
Every OS has different rules for configuration files placement, this module allows one to easily find and create your app configuration files following those rules.
Config::Find references configuration files by the application name or by the application name and the configuration file name when the app uses several application files, i.e
By default the $0 value is used to generate the configuration file name. To define it explicitly the keywords
names have to be used:
picks the first configuration file matching that name.
picks the first configuration file matching any of the names passed.
Alternatively, the exact position for the file can be specified with the
explicit position of the configuration file.
If undef is passed this entry is ignored and the search for the configuration file continues with the appropriate OS rules. This allows for:
use Config::Find; use Getopt::Std; our $opt_c; getopts('c:'); my $fn=Config::Find->find(file => $opt_c)
Methods in this package also accept the optional arguments
Configuration files can be private to the application user or global to the OS, i.e. in unix there is the global
/etc/profile and the user
read mode already existent file names are returned, in
write mode the file names point to where the configuration file has to be stored.
All the methods in this package are class methods (you don't need an object to call them).
returns the name of the configuration file.
returns a open file handle for the configuration file. In write mode, the file and any nonexistent parent directories are created.
copies a configuration file to a convenient place.
Some Win32 operating systems are not completely implemented and default to inferior modes, but hey, this is a work in progress!!!
Contributions, bug reports, feedback and any kind of comments are welcome.
Config::Find::Any for information about adding support for a new OS.
Config::Auto give me the idea for this module.
