Constructor Details

#initialize(fuse_object, mountpoint, *options) ⇒ FuseDelegator

Create and mount a filesystem

Parameters:

  • fuse_object (Object) —

    your filesystem object that responds to fuse methods

  • mountpoint (String) —

    existing directory where the filesystem will be mounted

  • options (String...) —

    fuse mount options (use "-h" to see a list)

def debug=(value)
    value = value ? true : false
    if @debug && !value
        $stderr.puts "=== #{ self }.debug=false"
    elsif !@debug && value
        $stderr.puts "=== #{ self }.debug=true"
    end
    @debug = value
end

#debug? ⇒ Boolean

Note:

this is independent of the Fuse kernel module debugging enabled with the "-d" mount option

RFuse Debugging status

Returns:

  • (Boolean) —

    whether debugging information should be printed to $stderr around each fuse method. Defaults to $DEBUG
