One of the most recurring requirement from users of the Rodin platform is to have simple means for renaming modeling elements.  Users want to have a unique operation that will rename an element both at its declaration and all its occurrences. Moreover, they require that renaming an element doesn't modify their existing proof state (no loss of proof).

* [[Help:Variables|Variables]]

* [[Help:Namespaces|Namespaces]]
  
This requirement falls in the more general context of ''refactoring''. In software engineering, "refactoring" source code means improving it without changing its overall results, and is sometimes informally referred to as "cleaning it up". In the case of the Rodin platform, the refactoring framework is related to the first option, where refactoring should not change the overall behaviour of the files/elements, nor loosing proofs.

Currently, it is being developed the application of such framework to event-b files (context, machines, proofs obligations, etc) and elements (constants, variables, carrier sets, etc). There are still some tests to be run for the different elements of contexts and machines. The next goal would be to apply and use this framework on Rodin (together with file editors or perspectives).

The following features require extra permissions that are not normally granted to all wiki users.

__NOTOC__
Since there are proof obligations associated with Event-B files, while renaming the goal would be to cause the less effort as possible on re-proving and if possible re-using the proofs that are already discharged. The refactoring should not change the semantic of any of the elements/files. Instead, it should just change names or labels, so the proofs should not have to be re-generated (nor re-discharged). That is one of final goals while applying of this framework to Event-B.
 
 
 
==Initial Work ==
 
 
 
Initial work towards implementation of this framework is described in [http://www.stups.uni-duesseldorf.de/thesis_detail.php?id=9 Sonja Holl's Bachelor thesis]
 
 
 
==Installing/Updating ==
 
 
 
The installation or update for the renaming/refactoring plug-in is available under the main Rodin Update site (http://rodin-b-sharp.sourceforge.net/updates) and category 'Utilities'. Like always, after the installation, restarting the application is recommended.
 
 
 
==Usage ==
 
 
 
The Renaming/Refactory plug-in allows the renaming of:
 
 
 
* Variables
 
* Parameters
 
* Carrier Sets
 
* Constants
 
* Events
 
* Other labelled elements (invariants, axioms, guards, etc)
 
 
 
====Requirements before using ====
 
 
 
Before using the renaming/refactory, all the files in the project should be saved ( it will be asked to save if there are unsaved files). There should be no errors in the project, otherwise it could lead to even more errors after applying the renaming (warning).
 
 
 
==== Steps of usage ====
 
 
 
# User selects element to be renamed at the Event-B Explorer
 
# By right clicking in the element, there should appear an option 'Refactory...'. Selecting that option should open a wizard [[Image:refactory menu.png]]
 
# User introduces new element name in the first page of the wizard. Then click in 'Next'. [[Image:new_name_wizard.png]]
 
# A list of related files is created and the plug-in check for possible clashes and returns a report
 
# User decides if he wants to execute renaming (by clicking in 'Finish')

== Bugs, Features and Comments ==
 
 
 
''Any reports of bugs, features or comments are welcome. You can add any of them here.''
 
 
 
====Bugs ====
 
* Renaming fails when renaming an event whose machine is refined (fixed in v0.0.7)
 
* Renaming all proofs after renaming (fixed in v0.0.6)
 
* Renaming does not work when renamed element is in variant (fixed in v0.0.5)
 
* Renaming proofs did not propagate over related files (fixed in v0.0.5)
 
 
 
====Features Request====
 
* Support for Records plug-in
 
* Implement UNDO for renaming

== Releases ==
 
 
 
=====Version 0.0.7 =====
 
 
 
''30th March 2010''
 
 
 
A release of renaming/refactory (v0.0.7) compatible with Rodin v1.2.x is available in the main Rodin update site.
 
 
 
*Bug Fix
 
**Fix bug that occurred when renaming an event whose machine was refined.
 
 
 
=====Version 0.0.6 =====
 
 
 
''25th February 2010''
 
 
 
A release of renaming/refactory (v0.0.6) compatible with Rodin v1.2.x is available in the main Rodin update site.
 
 
 
*Feature Request
 
**Renaming of all proofs after the element renaming. For each proof obligation, if proof rebuilding does not work, a new proofTree is created based on the initial proofTree and on the renamed element. By applying the ancient rule, if a proof is discharged before the renamed, it remains discharged after the renaming.
 
 
 
=====Version 0.0.5 =====
 
 
 
''13th January 2010''
 
 
 
A release of renaming/refactory (v0.0.5) fixing a few bugs found is already available.
 
 
 
=====Version 0.0.4 =====
 
 
 
''5th November 2009''
 
 
 
A release of renaming/refactory (v0.0.4) compatible with Rodin v1.1.0 is available in the main Rodin update site (bug fix from 0.0.3). Before starting the renaming, it is recommended to clean and build the project in order to have the indexer tables updated (IMPORTANT).
 
 
 
*Bug fix
 
** Renaming of proofs would not save the proof files after renaming
 
** Renaming of labelled elements would not update the proofs.
 
 
 
*Possible Problem
 
** If you try to rename and the operation runs successfully without any errors but does not have any effect, you should:
 
*** First, try to fix the renaming manually on the respective file (or using the renaming framework, revert to the original name)
 
*** Try to make a CLEAN and BUILD to ensure that the Rodin indexer is updated before the renaming.
 
*** Run the renaming again and should be working fine.
 
 
 
=====Version 0.0.3 =====
 
 
 
''2nd November 2009''
 
 
 
A release of renaming/refactory (v0.0.3) compatible with Rodin v1.1.0 is already available in the main Rodin update site. Before starting the renaming, it is recommended to clean and build the project in order to have the indexer tables updated.
 
 
 
*Features
 
** Renaming of machines and contexts is possible using the indexers. After the renaming of a machine/context, the change is propagated over the related files
 
** Renaming of proofs: after the renaming, the proof obligations are also updated to reflect the renaming. It might be necessary to manually refresh the status of some proof obligations (although the proof is already discharged). This renaming is not fully-functional at the moment and some discharged proof obligations may have to be discharged again. We intend to fix this problem in the future.
 
 
 
=====Version 0.0.2 =====
 
 
 
''3rd July 2009''
 
 
 
*Bugs
 
** Validate if new name is in the list of reserved words of Event-B (dom,ran, card, etc)
 
 
 
=====Version 0.0.1 =====
 
 
 
''1st July 2009''
 
 
 
A release of renaming/refactory (v0.0.1) compatible with Rodin v1.0.0 is already available in the main Rodin update site.
 
 
 
Note that this version is still a prototype so prone to errors. So it is suggested to back up the projects before starting to use the renaming plug-in. The plug-in uses the most recent version of Rodin Indexer. Before starting the renaming, it is recommended to clean and build the project in order to have the indexer tables updated.
 
 
 
Although one of the goals is to the rename the respective proof obligations, this feature is not available in this version. It should be available in the next release. If you find bugs or errors, please let me know by updating this wiki-page or [mailto:ras07r@ecs.soton.ac.uk email].
