Config::Model::Backend::PlainFile - Read and write config as plain file VERSION
version 2.021 SYNOPSIS
use Config::Model; use Log::Log4perl qw(:easy); Log::Log4perl->easy_init($WARN); my $model = Config::Model->new; my $inst = $model->create_config_class( name => "WithPlainFile", element => [ [qw/source new/] => { qw/type leaf value_type uniline/ }, ], read_config => [ { backend => 'plain_file', config_dir => '/tmp', }, ], ); my $inst = $model->instance(root_class_name => 'WithPlainFile' ); my $root = $inst->config_root ; $root->load('source=foo new=yes' ); $inst->write_back ; Now "/tmp" directory will contain 2 files: "source" and "new" with "foo" and "yes" inside. DESCRIPTION
This module is used directly by Config::Model to read or write the content of a configuration tree written in several files. Each element of the node is written in a plain file. This module supports currently only leaf and list elements. In the case of "list" element, each line of the file is a value of the list. Methods read_leaf (obj,elt,check,file,args); Called by read method to read the file of a leaf element. "args" contains the arguments passed to read method. read_hash (obj,elt,check,file,args); Like read_leaf for hash elements. read_list (obj,elt,check,file,args); Like read_leaf for list elements. write ( ) "write()" will write a file for each element of the calling class. Works only for leaf and list elements. Other element type are skipped. Always return 1 (unless it died before). AUTHOR

Config::Model::SimpleUI - Simple interface for Config::Model VERSION
version 2.021 SYNOPSIS
use Config::Model; use Config::Model::SimpleUI ; use Log::Log4perl qw(:easy); Log::Log4perl->easy_init($WARN); # define configuration tree object my $model = Config::Model->new; $model->create_config_class( name => "Foo", element => [ [qw/foo bar/] => { type => 'leaf', value_type => 'string' }, ] ); $model ->create_config_class ( name => "MyClass", element => [ [qw/foo bar/] => { type => 'leaf', value_type => 'string' }, hash_of_nodes => { type => 'hash', # hash id index_type => 'string', cargo => { type => 'node', config_class_name => 'Foo' }, }, ], ) ; my $inst = $model->instance(root_class_name => 'MyClass' ); my $root = $inst->config_root ; # put data my $step = 'foo=FOO hash_of_nodes:fr foo=bonjour - hash_of_nodes:en foo=hello '; $root->load( step => $step ); my $ui = Config::Model::SimpleUI->new( root => $root , title => 'My class ui', prompt => 'class ui', ); # engage in user interaction $ui -> run_loop ; print $root->dump_tree ; Once the synopsis above has been saved in "", you can do: $ perl class ui:$ ls foo bar hash_of_nodes class ui:$ ll hash_of_nodes name value type comment hash_of_nodes <Foo> node hash keys: "en" "fr" class ui:$ cd hash_of_nodes:en class ui: hash_of_nodes:en $ ll name value type comment foo hello string bar [undef] string class ui: hash_of_nodes:en $ set bar=bonjour class ui: hash_of_nodes:en $ ll name value type comment foo hello string bar bonjour string class ui: hash_of_nodes:en $ ^D At the end, the test script will dump the configuration tree. The modified "bar" value can be found in there: foo=FOO hash_of_nodes:en foo=hello bar=bonjour - hash_of_nodes:fr foo=bonjour - - DESCRIPTION
This module provides a pure ASCII user interface using STDIN and STDOUT. USER COMMAND SYNTAX
cd ... Jump into node or value element. You can use "cd <element>", "cd <elt:key>" or "cd -" to go up one node or "cd !" to go to configuration root. set elt=value Set a leaf value. set elt:key=value Set a leaf value locate in a hash or list element. display node_name elt:key Display a value ls Show elements of current node help Show available commands. desc[ription] Show class description of current node. desc(elt) Show description of element from current node. desc(value) Show effect of value (for enum) CONSTRUCTOR
parameters root Root node of the configuration tree title UI title prompt UI prompt. The prompt will be completed with the location of the current node. Methods run_loop() Engage in user interaction until user enters '^D' (CTRL-D). BUGS
o UI should take into account experience. AUTHOR
