Introduction

The Rodin Editor plug-in provides a structured editor to model in Event-B withing Rodin. This editor uses a textual representation, and edition is done through an overlay text editor and action depending on the caret position in the text.
For more details about the principles of this editor, see the Rodin Editor Plug-in page.

IMPORTANT FOR RODIN PLATFORMS BELOW RODIN 2.5 : we identified a source of concurrency issue in the current version (0.5.0) of the plug-in.
The Rodin Editor is not maintained for these versions of Rodin since Rodin 2.4. Please try to upgrade your plaform to the latest version of Rodin available. To avoid any trouble, please do not generate files while having some Rodin Editor open, and edit only one model per project at once.

Installation

Setup

Since Rodin 2.4, the Rodin Editor is part of the core platform (i.e. it is pre-installed and available out of the box). Once you've installed Rodin 2.4 or upper, you are ready to use the Rodin Editor plug-in.

Release Notes

See Rodin Editor Release Notes


Editing

This is a small exercice to get used to the principles of the new structured editor. It is based on the 'Celebrity' project of the tutorial. You can download the resulting project here.
We will here build the context Celebrity_C0.

Create a context, add elements to it

Let's create a Rodin project, and add a context component called Celebrity_C0 to it.
-- By opening this context with the Rodin Editor (right click > Open with > Rodin Editor) you shall obtain the following:
RodinEditor UserGuide step1.png

This editor allows to do things based on the position of the caret.
-- The caret is place at the front of the context name, and this is fine because we want to add a constant to the context. -- To add a constant, right click and select '[Child]-> Add Constant' as in the picture below:

RodinEditor UserGuide step3.png

-- Save the file.
After saving the file, the error markers are recalculated, and you have an error that appears on the newly created constant 'cst1'.
You shall see something like this :

RodinEditor UserGuide step4.png

Note that you can visualize the error message by going over the error marker with the mouse.

-- Now we enter the edition mode by clicking inside the label 'cst1', as we want to name the constant 'cst1' to 'k'.

RodinEditor UserGuide step5.png

The overlay editor then appears (the background is grey and a box is drawn[see above]) and you can modify the label of the constant.
-- Modify the label to be 'k'and exit the overlay edition by pressing 'Enter' or click next to k. Note that because 'Enter' is used to enter or exit the overlay mode under the caret, in order to insert carriage return in text, you have to press CTRL+ENTER (Apple+Enter) on mac platforms.
You can then save the file.
You then see something like the following.

RodinEditor UserGuide step6.png

Then we want to give this constant an integer type. As the caret is near 'k', and k is a constant, we will use '[Sibling]-> Add sibling' command to add an axiom.
-- Right-click and select "[Sibling]-> Add Axiom" you see then that a new axiom was created, named 'axm1'.

RodinEditor UserGuide step8.png

You've just created an axiom that you can edit to give the constant k a type. You can then enter the overlay edition mode to change this value to 'k : INT'.
After saving the file, you obtain the following context :

RodinEditor UserGuide step9.png

and the markers disappear because there is no error left in your context. Finally, suppose that the axiom axm1 should be considered as a theorem, click on not theorem after the axiom formula, to change the attribute of the predicate to a theorem.

CONGRATULATIONS! You learned how to use the Rodin Editor. You learned that :

  1. To create an element:
    1. or you place the caret before the label of its parent, and create a child using '[Child]->Add xxx' where xxx is the type of element you want to add, from the contextual menu,
    2. or you place the caret next to a sibling element and you create a sibling using '[Sibling]->Add xxx' where xxx is the type of element you want to add, from the contextual menu.
  2. To edit the attributes of an element:
    1. you enter the overlay edition with left click or with "ENTER" and modify the textual contents,
    2. you press 'ENTER' to quit overlay edition (or click outside the overlay editor).

Select, Move and delete elements

-- To select elements, you have 3 choices:

  • you can double-click on them,
  • or press CTRL and click on one element,
  • or click on the visual circle handle at their left.

RodinEditor UserGuide step10.png

The selected elements appear with a blue background, or a gray background if they are of different types. See the picture below.

RodinEditor UserGuide step11.png

-- To unselect element, by default, press ESC.

-- To move elements, try both:

  • Move Up and Move Down commands in the context menu, once elements are selected,
  • Drag and drop on the selection.

-- To delete elements, try both:

  • Use the 'Delete' command on a selection from the context menu,
  • Press the DEL or SUPPR key after selecting the elements you want to delete.

Using keyboard shorcuts

Here is the list of the currently key bindings which are set by default and specific to the Rodin Editor.


KEY SEQUENCE ACTION
BACKSPACE (ENTER) Enter the edition mode using the overlay editor if the caret is on an editable place.
DEL Suppress the element after the caret position
ALT+T Add a sibling of the element pointed by the caret position. The sibling is placed just after this latter one.
ALT+G Opens a popup to select the element type of the child to add to the element pointed by the caret position. Note that if there is only one child type, the child will be directly created.
CTRL+BACKSPACE Insert a new carriage return while editing with the overlay editor.
ALT+ARROW_UP Move up the selected elements.
ALT+ARROW_DOWN Move down the selected elements.
SHIFT+ARROW_UP Select elements up.
SHIFT+ARROW_DOWN Select elements down.
ESC Quit the current overlay edition (if any) and forget the modifications made, frees the current selection.
TAB Go to the next editable place (i.e. to the next editable element attribute)
SHIFT+TAB Go to the previous editable place (i.e. to the next editable element attribute)

Customize these shortcuts

If you don't like these shortcuts, you can modify them by setting your own key preferences. To do so, go to Window > Preferences and then General > Key. A table appears were you can find and edit the shortcuts.
