Revision as of 14:38, 8 April 2010
The first version of the Text Editor will be released in the next weeks, that means in second half of June and not before the Rodin release 1.0 has been published.
Until then we are going to release a few testing releases (beta) for interested users. You will find instructions how to install and use these beta releases on this page.
See also: Camille_Release_History
Installing
The TextEditor relies on features of the Rodin release 1.0 which is not yet released. Therefore you will have to use the release candidate 1 of Rodin 1.0.0. The following steps will guide you through this process:
- Download Rodin_1.0.0_RC1 for your platform from Sourceforge:
- Extract the downloaded zip file.
- Start Rodin from the folder where you extracted the zip file in the previous step.
- Install the TextEditor:
- In the menu choose Help -> Software Updates...
- Select the tab Available Software and click Add Site...
- Use the location URL: http://www.stups.uni-duesseldorf.de/update-beta/
- Back in Available Software open the update site you just added
- Select Event-B EMF Framework and Event-B TextEditor and click Install...
- Restart Rodin as suggested.
Now you are ready to use the TextEditor.
Updating
As often as possible we are going to publish updated beta releases. We recommend that you update your new Rodin installation with these updates for the TextEditor (and EMF Framework).
Although we will try to announce these updates on this site too, it is a lot easier if you setup Rodin to let you know when an update is available. The following steps guide you through this process:
- In Rodin open the preferences (Window -> Preferences or for Mac: Rodin -> Preferences)
- Find Install/Update -> Automatic Updates
- Select Automatically find new updates and notify me
As soon as Rodin finds a new update it will ask you if you would like to install it.
This is how it should work. Unfortunately the update doesn't always notify the user properly. So we recommend checking for updates regularly or watching this page for changes. We will announce updates on this page too.
Usage
This section should help you to get started with the TextEditor.
To get a first impression also visit the screenshot page.
Opening with the TextEditor
The TextEditor competes with the current graphical Event-B editor when it comes to the selection of a default editor for the double click action to open a model file. To explicitly select which editor should be used please select Open with... in the context menu of the component you want to open. In this menu you can select which editor is used. After opening a component with one editor this editor will be the default until you select another one.
Syntax
The text syntax for machines and contexts is closely related with the pretty-print you might know from the graphical Event-B editor. See the grammar's EBNF for details.
As you might notice in the grammar it only describes the structure of machines and contexts. For the terminals predicate, expression and action you can use the syntax for formulas which you already know from editing models with the graphical Event-B editor. You can use the ASCII representation of mathematical symbols or their unicode. See the Rodin help for details about the mathematical symbols and their ASCII counterparts.
Editing
The TextEditor currently offers the following features:
- Syntax error marking: Syntactical errors are highlighted in the input text.
- Mathmatical language: You can type formulas in ASCII syntax and the TextEditor will replace ASCII symbols with their unicode counterparts as soon as you stop typing for a short while.
- Syntax highlighting: Keywords (structural and in formulas), labels and comments are highlighted. This happends directly when typing.
- Semantic highlighting: Identifiers are highlighted based on their semantic meaning, i.e., as variables, constants, parameters, sets, local variables. This highlighting is updated when you stop typing for a short while.
- Configuration of highlighting: In the Rodin preference pages you will find a page for the highlighting in the TextEditor. It allows you to change color and style of highlighted text.
- Code completion: The following elements are available for code completion (invoked by Ctrl+Space on the most computers)
- Keywords
- Identifiers
- Templates (very few so far, please let us know which templates you would like to add)
- Outline View: An outline view gives you an overview of the model's structure.
- Quick Navigation: The outline view allows clicking on an element to jump to its position within the text.
Of course the TextEditor offers the common features you know from other text editors, such as: copy, paste, moving of text (try Alt+Up or Alt+Down), undo, redo, ...
Restrictions
Due to some design decisions and its combination with the Rodin platform the TextEditor comes with a few restrictions:
- Semantic analysis (for highlighting and code completion for example) can only performed if the overall structure of the input is parsable. Therefore you might experience situtions when the semantic highlighting or the code completion produces unexpected results because it is based on outdated parsing information.
- Parsing for formulas, i.e., predicates, actions and expressions can only be performed if the overall structure of the input is parsable. If the structure is not parsable ascii symbols will not be replaced until you correct the overall structure.
- Also see the EBNF page for some restrictions in the syntax.
Bugs and Features
Please use this section to report any bugs you find and let us know about features you would like to see in the TextEditor.
Regarding feature requests: Any feature request is welcome! But please keep in mind that we are preparing for a first stable release of the TextEditor. So we might not start working on your feature request in the next weeks. The focus until the first release is on stability!
Bugs
- [Systerel] Take into account language changes for rodin 1.0.0 (namely, theorem anywhere, which should impact the EBNF grammar)
- [Systerel] Text editor (rodin 1.0.0) exception when opening a recently converted component
- [Systerel] Text editor (rodin 1.0.0) is unable to save.
- [Systerel] java.lang.ArrayStoreException when refine an existing machine via the Refines item in the popup menu
- [CETIC] Out of memory exception when inputing a simple machine spec (available on request)
- [Soton] Referring to the following bug, on my machine is not only the following but most of B Symbols are not displayed properly. (I have the Text editor 0.0.6 / Rodin 1.0 on a Windows machine)
- [Bosch] The following symbols: partial injection, range substraction, total surjective relation, surjective relation are not displayed correctly in 0.0.6 / Rodin 1.0
- On Mac the relational override symbol is not displayed properly.
- Undo is behaving unexpectedly for formula symbols which are replaced. Reverting the replace is one undo step. But the symbol is replaced again if no second undo is invoked quickly enough.
- Bookmarks can be created, but they disappear when saving.
[Bosch] Ctrl+Space (Code Completion) produces a null pointer exeception if invoked in places where it should not be invoked (e.g. empty space in the editor etc.)fixed in version 0.0.6When a refines or sees references a not-existig machine/context the component is created on-the-fly without asking the user. Partly caused by a bug in the EMF persistence for Event-B.fixed in version 0.0.6- [Systerel] Some spurious spaces are sometime inserted (i.e. typing a[space]/=[space]b results in a[space]≠[space][space]b)
- [Systerel] Sometime, error marker appear on the wrong event.
Feature Requests
Add Auto-Formating (i.e., explicit call of the pretty-printer on CMD+SHIFT+F)fixed in version 0.0.6- Add other machines/contexts to code completion suggestions when completing after refines/sees
- Add hovers with additional information, such as the declaring machine/context
- Add jump-to-declaration action
- Select complete element (e.g. event) with double- or triple-click (Comment: CTRL+ARROW-UP is used in Eclipse)
- Lock keywords so they cannot be changed anymore
- Highlight matching paranthesis
- Make TextEditor an Eierlegende Wollmilchsau... ;-)
- [Bosch] Provide folding for Event-B model elements (similar to folding of Java methods)
- [Bosch] Provide refactoring of Event-B model elements
[Bosch, R1] Provide symbol table; see http://bscw.cs.ncl.ac.uk/bscw/bscw.cgi/d100429/DEPLOY_082_1th_ReportToolReq.pdffixed in version 0.0.6- Due to the restriction that the editor only accepts labels without whitespaces some models do not parse in the text editor. Informing the user about this problem when opening such a file would be helpful. An alternative is to automatically change labels and replace a whitespace with a '_'. The latter is only reasonable if the user knows what happens (might lose proofs) or when a refactoring is available which preserves proofs.
- Add code completion for labels
Comments
Of course any other feedback is welcome too! We appreciate when you let us now what you think about the TextEditor.
