## Pm tool
A set of commands is offered to observe, explore, edit, diff, export, provision or create a new provisioning state.

### Observing an installation or feature-pack.

_[my-dir]$ state info <stream name | --dir=installation> --type=[configs|dependencies]_

Display the set of dependencies and/or configurations. All is displayed by default.

### Exporting an installation to xml

_[my-dir]$ state export <new generated xml file> --dir=<installation>_

###  Provisioning an installation from xml

_[my-dir]$ state provision <xml file> --dir=<target installation directory>_

### Exploring an installation or a feature-pack.

_[my-dir]$ state explore <[stream name|--fp=coords] | --dir=installation> +
[/]$ ls +
configs +
feature-specs +
packages +
[/]$ state leave +
[my-dir]$_ +

Once exploring, prompt, ls, cd and pwd commands are bound to the feature-pack (or installation) exposed file-system. +
The fs is composed of: +
/configs/final/<model>/<name>/<features> +
/feature-specs/<origin>/<feature-specs> +
/packages/<origin>/<packages> + 
Features and feature-specs are organized as a file system with containment. +
The set of available commands is limited when in “navigation mode”. 
Only “cd, ls, pwd and state info|leave” are available. Use state leave to exit this mode.

TIP: Use ‘ls’ to visualize any item. Use ‘cd’ to navigate to a given node.

### Searching the current state

When exploring, editing or composing a new state, one can search the packages and features.

_[/]$search [--query=<some text> | --package=<package name>]_

When searching with _--query_ all packages and features are looked-up for a match. If packages are matched, the features
that depend directly or indirectly on these packages will be shown in the result.

When searching with _--package_, the package completer can be used. The features that depend directly or 
indirectly on this package will be shown in the result.

### Creating a new state (or editing an existing state from an installation or provisioning XML file)

This allow to start from an empty installation or re-use an installation and iteratively add/suppress content. +

_[my-dir]$ state new  | state edit <path to installation | path to provisioning XML file> +
[/]$ <TAB> +
cd feature-pack ls pwd state +
[/]$ ls +
configs +
dependencies +
feature-specs +
packages_

The filesystem is similar to explore, with the addition of dependencies that contains full content of all added feature-packs. 

NB: Each action as the effect to build a runtime with the current state. The filesystem reflects the current state.

NB: Each action applied to a state in edition can be undone: _undo_. Use _state leave_ to exit the composition mode.

NB: The set of exposed commands by completer is dynamic and is adjusted according to the current state.

### Exporting or provisioning the current state

At any time, one can export the provisioning XML file or directly provision from the current state:

_[/]$ state export <path to generated xml file> | state provision <dir of new installation>_

TIP: Use state export to validate that what you get in the XML is in sync with the expose state. In case you find something wrong, shout to me ;-)!

TIP: The command state info can be used to get high level information. I am wandering if we shouldn’t have a flag to display the full XML in the console instead of heaving to read an external file. Possible TODO.

### Adding a feature-pack

_[/]$ feature-pack add <stream | --fp=coords> [--default-configs-inherit] [--packages-inherit]_ +

By default nothing is inherited. Once at least one feature-pack has been added, configurations or packages can be handled. 

NB: A runtime based on the added full feature-pack is built in order to retrieve dependencies content and some completion content. This structure is cached for re-use.

### Removing a feature-pack

_[/]$ feature-pack remove <fpcoord for now>_

### Including a default configuration

_[/]$ config include <model>/<name> [--origin=<fp coords>]_

Origin is optional, by default will be included from all fp that expose it.

### Removing an included default configuration

_[/]$ config remove-included <model>/<name> [--origin=<fp coords>]_

The completer only proposes the set of configurations that have been previously included. Same for fp.
Origin is optional, by default will be remove from all fp that include it.


### Excluding a default configuration

_[/]$ config exclude <model>/<name> [--origin=<fp coords>]_

Origin is optional, by default will be excluded from all fp that expose it.

### Removing an excluded default configuration

_[/]$ config remove-excluded <model>/<name> [--origin=<fp coords>]_

The completer only proposes the set of configurations that have been previously excluded. Same for fp.
Origin is optional, by default will be remove from all fp that exclude it.


### Reseting a configuration

_[/]$ config reset <model>/<name>_

The custom content of this configuration is removed.

NB: This has no effect on included/excluded configurations.

### Including a default package

_[/]$ packages include <fpcoord for now>/<package name>_

### Removing an included default package

_[/]$ packages remove-included <package name> [--origin=<fp coords>]_

The completer only proposes the set of packages that have been previously included.
The origin is optional, the package will be removed from all fp that exclude it.

### Excluding a default package

_[/]$ packages exclude <fpcoord for now>/<package name>_

### Removing an excluded default package

_[/]$ packages remove-excluded <package name> [--origin=<fp coords>]_

The completer only proposes the set of packages that have been previously excluded.
The origin is optional, the package will be removed from all fp that exclude it.

### Adding a new feature

_[/]$ feature add <config model/name> <path to feature-spec>  <dynamic set of feature param=<value>>_

For example: +
_feature add standalone/standalone.xml org.wildfly.core:wildfly-core-feature-pack-new/interface --interface=toto --inet-address=127.0.0.1_

NB: All parameters are exposed as command option.
 
NB: All parameters that are not nillable and have no default values are required. The command being aborted if there are missing required parameters. 

NB: If the parameter is not present, its default value is injected when creating the feature.

NB: The current location (thanks to cd) is not yet taken into account when completing/adding the feature. That is a TODO.

NB: A feature with the same feature-id can’t exist. A single feature with the given feature-id per config.

### Removing a feature
_[/]$ feature remove <full path to feature inside a configuration>_

For example: +
_feature remove standalone/standalone.xml/interface/toto_
