Research:SWT - urschleim/scream GitHub Wiki
A frontend using the Eclipse SWT framework should be the strategic goal for scream.
Reasons are many features that the classes from Eclipse deliver already, like:
- Brace balancing.
- Keyword expansion.
- Ready made forms for expressions like
let
et al. - Text editors.
Complexity threshold for SWT development is high, information seems good on a first glance, but is outdated and has dead ends.
Strategy
Levelled approach.
Level 1 -- Hello scream
Based on SWT, create a simple stand-alone application, offering only a single window that represents a (REPL-) console. That is, it is possible to enter Scheme-expressions that are executed and whose results are printed in the console. The coupling between the console and the scream kernel is based on the interface offered by de.michab.scream.SchemeEvaluator
.
Level 2 -- Extend
Add functionality like a persistent history between runs.
Level 3 -- More
- Split UI in composition window, output window, error out, standard out.
Level 4 -- get on par with the Swing implementation
- Remove Swing stuff
Level 5 -- continue evolving SWT
- SWT is now base for the UI and is part of normal feature flow.
