HTML / Xion Editor

The bodies of the methods (accessible by double-clicking on the method in the browser, or using the operation or method popup menu) are defined using the action language Xion.

This editor is also used by clicking an "Open in a window" button, in some parts of the navigation diagram (editing entry actions, default values, expressions...). It is equally used to edit HTML (thanks to the button "Open in a window") in a larger window, with some differences explained  here.

As Xion editor		As HTML editor

The main part is the text pane. The syntaxic coloration is automatic and depends on the fact that you are editing Xion or HTML.

Common functionalities

If the text has changed, quitting or compiling the project will cause the editor to ask for saving.

Settings

There are about the same settings for Xion and for HTML, but they are applied only in their specialty. For instance, changing the background color for the HTML editor will not change the background color for the Xion editor. Settings are saved for a specific user.

Settings are edited calling File/Options menu. This opens a dialog. At the left, you can find an example of the entered settings, at the right, there are tabbed panes. At the bottom, there are four buttons:

• Default applies the default settings
• Reset applies the current settings
• Cancel quits the settings editor without saving
• OK quits the settings editor saving and applying them to the current and new windows

Tabs are font, colors and properties.
Font pane allows change font for HTML/Xion specific syntactic elements. You can select them in the top combo box, or by clicking on the example panel. The default font and the default size are the default java ones.

The colors tab pane allows to change text color for HTML/Xion specific syntactic elements, plus:

• Caret color: the color of the caret sign (a | at the position of the caret) - if the property "Caret visible" is enabled
• Selection color:  the background color of a selected text
• Line highlight color: the background color of the line of the caret - if the property "Line highlight" is enabled
• Bracket highlight color: the color of the bracket highlight - if the property "Bracket highlight" is enabled
• End of line marker color: the color of the end of line marker - if the property "End of line marker" is enabled
• Background color: the background color...

There are different color selection modes: Swatches presents a collection of colors on witch you can click, HSB allows to compose a color thanks to hue, saturation and brightness properties, and RGB allows to compose a color thanks to red, green and blue ratios.

The properties tab allows to edit different properties:

• Caret visible: enable a | sign at the caret position
• Caret blinks: make the | sign at the caret position blink - if the property "Caret visible" is enabled
• Caret as block: if enabled, the | sign for the caret is replaced by a   one
• Line highlight: enable a special background color for the line where the caret is
• Bracket highlight: enable a _ sign underlining the ( corresponding to the ) preceding the caret
• End of line marker: enable a • sign at the end of each line
• Tab size: the size of a tab; 1 corresponds to the size of the w letter in the default font
• Auto-tabulate: a return automatically insert tabulations, to start at the same position of the last written line

• Verify: checks the code validity; errors and warnings appear in the bottom list
• Propose Type: tries to perform a semantic completion
