37 File "foo.conf" now contains:
38
39 ## This file was written by Config::Model
40 ## You may modify the content of this file. Configuration
41 ## modifications will be preserved. Modifications in
42 ## comments may be mangled.
43 ##
44 foo="FOO1"

46 bar="BAR1"

49 This module is used directly by Config::Model to read or write the
50 content of a configuration tree written with "SHELLVAR" syntax in
51 "Config::Model" configuration tree.
52
53 Note that undefined values are skipped for list element. I.e. if a list
54 element contains "('a',undef,'b')", the data structure contains
55 'a','b'.
56
58 new
59 Parameters: "( node => $node_obj, name => 'shellvar' )"
60
61 Inherited from Config::Model::Backend::Any. The constructor is called
62 by Config::Model::BackendMgr.
63
64 read
65 Of all parameters passed to this read call-back, only "file_path" is
66 used.
67
68 When a file is read, "read" returns 1.
69
70 write
71 Of all parameters passed to this write call-back, only "file_path" is
72 used.
73
74 "write" returns 1.
