NAME ^

Config::Find - Find configuration files in the native OS fashion

SYNOPSIS ^

  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 );

ABSTRACT ^

Config::Find searchs for configuration files using OS dependant heuristics.

DESCRIPTION ^

Every OS has different rules for configuration files placement, this module allows 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 emacs, profile, apache/httpd, apache/ssl.

By default the $0 value is used to generate the configuration file name. To define it explicitly the keywords name or names have to be used:

name => name or app/file

picks the first configuration file matching that name.

names => [qw(foo bar foo/bar)]

picks the first configuration file matching any of the names passed.

Alternatively, the exact position for the file can be specified with the file keyword:

file => /config/file/name.conf

explicit position of the configuration file.

If undef is passed this entry is ignored and the search for the configuration file continues with the apropiate 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 scope and mode:

scope => user or global

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 ~/.profile.

mode => read or write

In read mode already existant file names are returned, in write mode the file names point to where the configuration file has to be stored.

METHODS

All the methods in this package are class methods (you don't need an object to call them).

$fn=Config::Find->find(%opts)

returns the name of the configuration file.

$fh=Config::Find->open(%opts)

returns a open file handle for the configuration file. In write mode, the file and any nonexistant parent directories are created.

$fn=Config::Find->install($original, %opts)

copies a configuration file to a convenient place.

EXPORT

None, this module has an OO interface.

BUGS ^

Some Win32 OSs 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.

SEE ALSO ^

Config::Find::Unix, Config::Find::Win32 for descriptions of the heuristics used to find the configuration files.

Config::Find::Any for information about adding support for a new OS.

Config::Auto give me the idea for this module.
