NAME

config-edit - Edit data of configuration managed by Config::Model

SYNOPSIS

config-edit [options] -model Fstab [ commands  ... ]

DESCRIPTION

Config-model is a general purpose configuration framework.

The config-edit program will use Config::Model configuration descriptions to provide a user interface so user can easily and securely modify the configuration of their system.

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.

Options

-model

Mandatory option that specifies the configuration data to be edited. The model must be available in /etc/config-model.d/ directory in a .pl file. E.g. this command:

config-edit -model Fstab

will look for /etc/config-model.d/Fstab.pl model file. See Config::Model for more details.

-ui

Specify the user interface type.

-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.

-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

-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)

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 (slowly) moved from klunky debug and verbose prints to Log::Log4perl. Use can configure logging in the following files:

  • /etc/log4config-model.conf

  • ~/.log4config-model

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:

Model
Model::Load
Data::Read
Data::Write
Tree::Element::Value
Tree::Element::Warper

More categories will come.
