boolean record = true; causes a syntax error even thought it is valid Java #1241
Description
Most appropriate sub-area of Processing 4?

Processing version
main
Operating system
macOS/Windows/Linux?
Bug description
Adding boolean record = true; anywhere to the sketch causes the preprocess to emit an Error even though it is valid Java.
This is what I know so far:
recordis a java keyword- changing it to
boolean record1 = true;suppresses the error - I tried changing the antlr version back to what it was defined in the Ant build system but that didn't help either
Steps to reproduce this
-
Add
boolean record = true;to a sketch -
See the preprocessor be unhappy
snippet
boolean record = true;
void setup() {
}
void draw() {
}Additional context
No response

Lines 109 to 110 in 275d789
Here it is defined in the Lexer
and here most of it in the Parser

Changing the string in the top does make the error go away but that of course moves it to a separate keyword

Cool, the antlr stuff has been an antler (pun intended) in my side for a while so it'd be nice to share this :)
