NAME

config-edit - Deprecated, use cme

SYNOPSIS

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

DESCRIPTION

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 Config::Model::Loader.

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

Graphical interface

config-edit -application popcon

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

Curses interface

config-edit -ui curses -application popcon

Provides a curses user interface

Shell like interface

config-edit -ui shell -application popcon

Provides a shell like interface

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.

Direct modification of configuration data

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

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

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

Options

application

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

file

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

-model

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

-ui

Specify the user interface type.

  • tk: provides a Tk graphical interface (If Config::Model::TkUI is installed).

  • curses: provides a curses user interface (If Config::Model::CursesUI is installed).

  • shell: provides a shell like interface. See Config::Model::TermUI for details.

  • 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 -fuse_dir. To stop (and write the configuration data back to the configuration file), run fusermount -u <mounted_fuse_dir>. (This is experimental. Mount point specification may change in the future)

  • none: No UI provided. Only command line arguments are handled.

-dev

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

-model-dir

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

-instance-name

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

-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 -model option). For instance, if you specify ~/mytest, the /etc/ssh/sshd_config files will be written in ~/mytest/etc/ssh/ directory.

-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.

-verbose

Be (very) verbose

-debug

Provide debug infos.

-trace

Provides a full stack trace when exiting on error.

-force-load

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

-apply-fixes

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

-backend

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

-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

-dumptype [ full | preset | custom ]

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

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

-save

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

-open-item 'path'

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

-open-item 'foo bar'
-fuse-dir

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

Search

You can search the configuration with the following options

-search

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

-narrow-search

Narrows down the search to:

element
value
key
summary

Summary text

description

description text

help

value help text

Embedding config-edit

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

Saving configuration data

Configuration data are saved only when :

  • Requested through the user interface

  • When commands are specified with arguments

  • When -load option is used

  • When -save option is used

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

Logging

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

  • ~/.log4config-model

  • /etc/log4config-model.conf

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:

Anything
Backend
Backend::Debian::Dpkg
Backend::Debian::Dpkg::Control
Backend::Debian::Dpkg::Copyright
Backend::Fstab
Backend::IniFile
Backend::PlainFile
Backend::ShellVar
Backend::Yaml
FuseUI
Instance
Loader
Model::Searcher
Tree::Element::CheckList
Tree::Element::Id
Tree::Element::Id::Hash
Tree::Element::Id::List
Tree::Element::Value
Tree::Element::Value::Dependency
Tree::Node
Tree::Node::Warped
ValueComputer
Warper
Wizard::Helper
Model

More categories will come.
