Mu
A small expression parser, using ANTLR 4. It supports most basic operators
and while- and log- (print) statements. It is just a basic
demonstration of how to use the -visitor functionality of ANTLR 4.
To run the demo script:
n = 9;
while n > 0 {
# expressions can be surrounded by parenthesis, of course
if (n % 2 == 0) {
log n + " -> even";
}
else {
log n + " -> odd";
}
n = n - 1;
}
do:
git clone git://github.com/bkiers/Mu.git
mvn clean install
mvn -q exec:java
which will print the following to your console:
9.0 -> odd
8.0 -> even
7.0 -> odd
6.0 -> even
5.0 -> odd
4.0 -> even
3.0 -> odd
2.0 -> even
1.0 -> odd
