Syntax checking/Visualisation

back to Syntax checking page

Work distribution for Milestone on June 15.

• Oli: find out how to add data to the EV_OUTPUT pane; do a proof of concept
• Mätthu: find out how to draw a popup window; do a proof of concept
• Fabi & Janick: find out how to go from keyboard x,y to token and from mouse x,y to token (or to keyboard x,y , then to token); add those features to editor

Status token from moue/keyboard

relevant data in EB_CLICKABLE_EDITOR

Underlining proof of concept from May 23.

Summary of the important classes with little description of the features we plan to use:

Src\library\editor\text_window\text\tokens\common\editor_token.e

• most important class
• all the other tokens inherit from this Class
• implement a boolean "is_correct”, who indicates if the token is syntacticly correct or not.
• color, position and other stuff is saved here too.

editor_token_text.e

• top token class for all text-related tokens
• width -> the size of the token in pixel
• display_with_colors: this should be the feature we could hook to do draw our underlining

Src\library\editor\text_window\editor\text_window\interface\text_panel.e

• container containing tokens

Next Steps are to implement the boolean (shouldn't be that hard), find a way to get the information from the parser group (define an API), use the information and set the boolean and in the end draw the underline.

TEXT_OBSERVER, EDITABLE_TEXT_PANEL.on_char may be relevant for parser hook too!
