Super nice parser improvements soon available
In the last week Iâve worked on doing several enhances to the parser
https://github.com/pharo-project/pharo/pull/7411 <https://github.com/pharo-project/pharo/pull/7411>
Besides several refactorings and cleanups, major changes include:
- we are able to correctly detect unfinished statements (missing dots) - we are able to correctly detect unreachable statements (like a statement after a return statement)
And we still continue parsing. This makes that the faulty parser used for syntax highlighting and other much more precise, and several of my touches also fix some of the exceptions found while typing (that were due to wrong behaviours on the parser).
Also I did a small iteration on top of the âsyntax feedbackâ so itâs less noisy. We can remove it at any time (thatâs just removing a configuration). But Iâd like more feedback before :)
To see the improvements
Pharo 8
Pharo9 previous to these changes
Pharo9 with these changes
Now, Iâll not deny this is still perfectible, as everything, but we can do another iteration on top :)

That is awesome work - I love you guys for continuing to improve this stuff! Itâs inspiring... Tim
