=head1 NAME

config-edit - Deprecated, use L<cme>

=head1 SYNOPSIS

  config-edit [options] ( -application popcon | -model Popcon ) [ ... ] [ commands  ... ]

=head1 DESCRIPTION

C<config-edit> program will use Config::Model configuration
descriptions to validate or modify the configuration file of an application.

You can specify commands as arguments that will be run on the
configuration root before launching the UI. These command follow the
syntax defined in L<Config::Model::Loader>.

C<config-edit> can be run in several modes depending on your needs.

=head2 Graphical interface

  config-edit -application popcon

Provides a user interface so user can easily and
securely modify the configuration of their system.

=head2 Curses interface

  config-edit -ui curses -application popcon

Provides a curses user interface

=head2 Shell like interface

  config-edit -ui shell -application popcon
  
Provides a shell like interface

=head2 upgrade mode

  config-edit -ui none -application popcon -save

Loads configuration date, perform validation and migration of old data 
(if specified by the model) and save the new configuration file.

=head2 Direct modification of configuration data

  config-edit -ui none -application popcon PARTICIPATE=yes

Loads old configuration data, update C<PARTICIPATE> data, checks the modification 
and save the configuration back. Option C<-save> is not needed as the data was modified
by the command line.

=head2 Generation of configuration documentation

  config-edit -model Popcon -gen-pod [ output_dir ] 

Generate pod documentation on STDOUT or write them in the specified directory. Note that
one pod file will be created per class.

To get man pages or text docuement, you can pipe the output of the command:

 config-edit -model Popcon -doc  | pod2man > popcon-conf.3

=head1 Options

=over

=item application

Application name to be configured. Specify C<help> to get a list of available 
applications.

=item file

Configuration file name. Used only for models without standard configuration 
file name. (e.g. multistrap)

=item -model

Specifies the model used to edit configuration data. Specify C<help> to
get a list of available applications. This option is ignored when C<-
application> is specified

=item -ui

Specify the user interface type. 

=over

=item *

C<tk>: provides a Tk graphical interface (If L<Config::Model::TkUI> is
installed).

=item *

C<curses>: provides a curses user interface (If
L<Config::Model::CursesUI> is installed).

=item *

C<shell>: provides a shell like interface.  See L<Config::Model::TermUI>
for details.

=item *

C<fuse>: provides an interface through a FUSE virtual file system. You must give a directory where
the virtual file system will be mounted with option C<-fuse_dir>. 
To stop (and write the configuration data back to the configuration file), 
run C<< fusermount -u <mounted_fuse_dir> >>. (This is experimental. Mount point 
specification may change in the future)

=item *

C<none>: No UI provided. Only command line arguments are handled.

=back

=item -dev

Use this option if you want to test a model under development. This
option will add C<lib> in C<@INC> and use C<lib/Config/Model/models>
as model directory. This option is ignored when run as root.

=item -model-dir

Specify an alternate directory to find model files. Mostly useful for
tests.

=item -instance-name

Specify an instance name. By default the instance name is copied from
model name. 

=begin comment 

Could be useful for a backup config data feature. To be implemented

=end comment

=item -root-dir

Specify a pseudo root directory to read and write the configuration
files. (Actual default directory and file names depends on the model
(See C<-model> option). For instance, if you specify C<~/mytest>, the
C</etc/ssh/sshd_config> files will be written in C<~/mytest/etc/ssh/>
directory.

=item -config-file 

Specify the configuration file to edit (which may override the file specified by the model).
 Note that some applicaitions (like multistrap)
will require this option. For other models (like Debian::Dpkg), this option may not make sense
as several files are used.

=item -verbose

Be (very) verbose

=item -debug

Provide debug infos.

=item -trace

Provides a full stack trace when exiting on error.

=item -force-load

Load file even if error are found in data. Bad data are discarded

=item -apply-fixes

Apply fixes mentioned in model description. 
For details, see C<warn_if_match> or C<warn_unless_match> 
in L<Config::Model::Value/>. Configuration files will be saved if 
invoked with C<-ui none> .

=item -backend

Specify a read/write backend. The actual backend name depends on the model
passed to C<-model> option. See L<Config::Model::AutoRead> for details.

=item -dump [ file ]

Dump configuration content on STDOUT or in the specified with
Config::Model syntax.

By default, dump only custom values, i.e. different from application
built-in values or model default values. See -dumptype option for
other types of dump

=item -dumptype [ full | preset | custom ]

Choose to dump every values (full), only preset values or only
customized values (default)

=item -load <cds_file_to_load>

Load configuration data in model from cds file (using Config::Model
serialisation format, typically done with -dump option). When this
option is used, the usual configuration files will not be read.

If used with C<-ui none>, this option will load configuration data, 
validate it and save it in configuration file (if no error was found).

=item -save

Force re-writing the configuration. (useful for configuration upgrade)

=item -open-item 'path'

In graphical mode, force the UI to open the node specified. E.g.

 -open-item 'foo bar'

=item -fuse-dir

Directory where the FUSE virtual file system will be mounted (with C<-ui fuse>)

=back

=head1 Search

You can search the configuration with the following options

=over 

=item -search

Specifies a string or pattern to search. C<config-edit> will a list of path pointing 
to the matching tree element and their value. 
See L<Config::Model::AnyThing/grab(...)> for details
on the path syntax.

=item -narrow-search

Narrows down the search to:

=over 

=item element 

=item value 

=item key 

=item summary 

Summary text

=item description

description text 

=item help

value help text

=back

=head1 Embedding config-edit

You can use config-edit from another program by using C<-ui simple>
option. This way you will be able to send command on the standard input
of C<config-edit> and get the results from the standard output.

=head1 Saving configuration data

Configuration data are saved only when :

=over

=item *

Requested through the user interface

=item *

When commands are specified with arguments

=item *

When C<-load> option is used

=item *

When C<-save> option is used

=back

You can run safely C<config-edit -ui none> to test a configuration,
configuration files will not be modified in this case.

=head1 Logging

All Config::Model logging is now based on L<Log::Log4perl>. 
Logging can be configured in the following files:

=over

=item *

 ~/.log4config-model

=item * 

 /etc/log4config-model.conf

=back

Without these files, the following Log4perl config is used:

 log4perl.logger=WARN, Screen
 log4perl.appender.Screen        = Log::Log4perl::Appender::Screen
 log4perl.appender.Screen.stderr = 0
 log4perl.appender.Screen.layout = Log::Log4perl::Layout::PatternLayout
 log4perl.appender.Screen.layout.ConversionPattern = %d %m %n

Log4perl uses the following categories:

=over

=item Anything

=item Backend

=item Backend::Debian::Dpkg

=item Backend::Debian::Dpkg::Control

=item Backend::Debian::Dpkg::Copyright

=item Backend::Fstab

=item Backend::IniFile

=item Backend::PlainFile

=item Backend::ShellVar

=item Backend::Yaml

=item FuseUI

=item Instance

=item Loader

=item Model::Searcher

=item Tree::Element::CheckList

=item Tree::Element::Id

=item Tree::Element::Id::Hash

=item Tree::Element::Id::List

=item Tree::Element::Value

=item Tree::Element::Value::Dependency

=item Tree::Node

=item Tree::Node::Warped

=item ValueComputer

=item Warper

=item Wizard::Helper

=item Model


=back

More categories will come.
