Syntax checking/Visualisation

Proof of concept from May 23.

Meeting of the 12.05.06, Visualsation Team

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!
