VERSION

version 2.087

SYNOPSIS


# command line
mkdir mydir
cme fusefs popcon -fuse-dir mydir
ll mydir
fusermount -u mydir
# programmatic
use Config::Model ;
use Config::Model::FuseUI ;
my $model = Config::Model -> new;
my $root = $model -> instance (root_class_name => "PopCon") -> config_root ;
my $ui = Config::Model::FuseUI->new( root => $root, mountpoint => "mydir" );
$ui -> run_loop ; # blocking call
# explore mydir in another terminal then umount mydir directory

DESCRIPTION

This module provides a virtual file system interface for you configuration data. Each possible parameter of your configuration file is mapped to a file.

Example

 $ cme fusefs popcon -fuse-dir fused
 Mounting config on fused in background.
 Use command 'fusermount -u fused' to unmount
 $ ll fused

BUGS

  • For some configuration, mapping each parameter to a file may lead to a high number of files.
  • The content of a file is when writing a wrong value. I.e. the files is empty and the old value is lost.

constructor

new (...)

parameters are:
model
Config::Model object
root
Root of the configuration tree ("Config::Model::Node" object )
mountpoint

Methods

run_loop( fork_in_loop => 1|0, debug => 1|0)

Mount the file system either in the current process or fork a new process before mounting the file system. In the former case, the call is blocking. In the latter case, the call returns after forking a process that performs the mount. Debug parameter is passed to Fuse system to get traces from Fuse.

fuse_mount

Mount the fuse file system. This method blocks until the file system is unmounted (with "fusermount -u mount_point" command)
