NAME
File::MimeInfo::Applications - Find programs to open a file by mimetype
SYNOPSIS
use File::MimeInfo::Magic;
use File::MimeInfo::Applications;
my $file = '/foo/bar';
my $mimetype = mimetype($file)
|| die "Could not find mimetype for $file\n";
my ($default, @other) = mime_applications($mimetype);
if (defined $default) {
$default->system($file)
}
else {
# prompt user with choice from @others
# ...
}
DESCRIPTION
This module tries to find applications that can open files with a
certain mimetype. This is done in the way suggested by the freedesktop
Desktop Entry specification. This module is intended to be compatible
with file managers and other applications that implement this
specification.
This module depends on File::DesktopEntry being installed.
To use this module effectively you need to have the desktop-file-utils
package from freedesktop and run update-desktop-database after
installing new .desktop files. See
<http://www.freedesktop.org/wiki/Software/desktop-file-utils>.
At the moment of writing this module is compatible with the way Nautilus
(Gnome) and with Thunar (XFCE) handle applications for mimetypes. I
understand KDE is still working on implementing the freedesktop mime
specifications but will follow. At the very least all perl applications
using this module are using the same defaults.
EXPORT
All methods are exported by default.
METHODS
mime_applications(MIMETYPE)
Returns an array of File::DesktopEntry objects. The first is the
default application for this mimetype, the rest are applications
that say they can handle this mimetype.
If the first result is undefined there is no default application and
it is good practice to ask the user which application he wants to
use.
mime_applications_all(MIMETYPE)
Like mime_applications() but also takes into account applications
that can open mimetypes from which MIMETYPE inherits. Parent
mimetypes tell something about the data format, all code inherits
from text/plain for example.
"mime_applications_set_default(MIMETYPE, APPLICATION)"
Save a default application for this mimetype. This action will
affect other applications using the same mechanism to find a default
application.
APPLICATION can either be a File::DesktopEntry object or the
basename of a .desktop file.
"mime_applications_set_custom(MIMETYPE, COMMAND)"
Save a custom shell command as default application. Generates a
DesktopEntry file on the fly and calls
"mime_applications_set_custom". Returns the DesktopEntry object.
No checks are done at all on COMMAND. It should however contain at
least one word.
NOTES
This module looks for associations files in the order specified in
version 1.0 of the MIME applications specification. It will also attempt
a last-resort fallback to the legacy file
$XDG_DATA_HOME/applications/defaults.list. In all cases, it will only
write to the recommended per-user defaults file located at
$XDG_CONFIG_HOME/mimeapps.list.
