Config::Model 0.612

Config::Model provides a framework to help in validating the semantic content of configuration data. Config::Model can also be used to provide a semantic check of options of a complex program like mplayer or transcode. How does this work ? Using this project, a typical configuration validation tool will be made of 3 parts : - The user interface - The validation engine which is in charge of validating all the configuration information provided by the user. - The storage facility that store the configuration information Dont we already have some configuration validation tools ? Youre probably thinking of tools like webmin. Yes, these tools exist and work fine, but they have their set of drawbacks. Usually, the validation of configuration data is done with a script which performs semantic validation and often ends up being quite complex (e.g. 2500 lines for Debians xserver-xorg.config script which handles xorg.conf file). In most cases, the configuration model is expressed in instructions (whatever programming language is used) and interspersed with a lot of processing to handle the actual configuration data. Whats the advantage of this project ? The Config::Model projects provide a way to get a validation engine where the configuration model is completely separated from the actual processing instruction. The configuration model is expressed in a declarative form (i.e. a Perl data structure) which is always easier to maintain than a lot of code. The declaration specifies: - the structure of the configuration data (which can be queried by generic user interfaces) - the properties of each element (boundaries, check, integer or string, enum like type ...) - the default values of parameters (if any) - mandatory parameters - the targeted audience (intermediate, advance, master) - on-line help (for ach parameter or value of parameter) - the level of expertise of each parameter (to hide expert parameters from newbie eyes) So, in the end: - maintenance and evolution of the configuration content is easier - user will see a *common* interface for *all* programs using this project. - user will not see advanced parameters - upgrade of configuration data is easier and sanity check is performed - audit of configuration is possible to check what was modified by the user compat Whats New in This Release: - This release provides some bugfixes and some new features. - It has the ability to preserve the order of the keys of a hash element (ordered hash). - It has the ability to dump and read configuration data as a Perl data structure..
