| == Configuration ==
| |
|
| |
| === Event-B Explorer ===
| |
| By default, XContext files (extension ''bucx'') and XMachine files (extension ''bumx'') are not display in the ''Event-B Explorer''. To enable this, select ''Customize view'' for ''Event-B Explorer'' and uncheck the option ''All files and folders''.
| |
|
| |
|
| |
| == Editing ==
| |
|
| |
| === XContext ===
| |
| * Any file with extension ''*.bucx'' will be recognised as XContext file. As a result, XContext file can be created by the standard ''New File'' wizard of Eclipse.
| |
| * The XText syntax of XContext file (v0.0.3) is as follows.
| |
| XContext returns econtext::Context:
| |
| {econtext::Context}
| |
| (comment=(ML_COMMENT | SL_COMMENT))?
| |
| 'context' name=ID
| |

| === XMachine ===
| |
| * Any file with extension ''*.bumx'' will be recognised as XMachine file. As a result, XMachine file can be created by the standard ''New File'' wizard of Eclipse.

| === Type Setting Event-B Symbols ===
| |
| The Event-B Symbols are supported via Content assist, e.g., when type setting invariant or action. Sometime, a preceding blank space is required to enable the correct content assist.
| |
|
| |
| == Converting Rodin files to Event-B XText ==
| |
| Rodin contexts and machines can be converted to XContext and XMachine files using context menu. From the ''Event-B Explorer'', right click on a Rodin project, a Rodin context, or a Rodin machine will offer option ''Convert to XText''. When a Rodin project is selected, all Rodin contexts and machines within that project will be converted.

IMPORTANT: Event-B XText Front-end is now developed into extended Event-B (XEvent-B).
The complete Event-B XText Front-end User Guide is available as pdf here. Some important information is listed below.
Introduction
The Event-B XText front-end provides text editors for XContexts and and XMachines which then compiled automatically to Event-B contexts and machines.
For more details about the principles of this editor, see the Event-B XText Front-end page.
Installation
Setup
Release Notes
See Event-B XText Front-end Release Notes
IMPORTANT
- Currently, Event-B XText front-end ONLY supports "standard" Event-B machines and contexts.
- Since the XContexts and XMachines are compiled to the Rodin files, the corresponding Rodin contexts and machines will be OVER-WRITTEN. Any changes in the Rodin files will not be lost.
- DO NOT USE the Event-B XText Front-end if you use modelling plug-ins such as iUML-B state-machines and class-diagrams, as the additional modelling elements will be over-written.
KNOWN ISSUES
- Converting to XText: Currently, the "extended" attribute of events are not serialised.
