A simple language that transpiles to brainfuck:
byte a
byte b
a = 3 + a
a = 33 + a
a = a + 2
byte c
a = a + 21
a = a + 2
b = 10 + a
c = a + b
print c
Transpiles to:

go run . examples/abc.mf
To compile mindfck into a binary:
go build .
Once the compiler is ready, you can compile mindfck (.mf) files into brainfuck:
minfck examples/abc.mf
To compile and execute the brainfuck code directly:
minfck example.mf --run
Q: Is this useful?
A: No
Q: Is it fun?
A: Also no
- Variables
- Byte, can be assigned with numbers or char values
- Math operations
- Logical operations
- If ... Else
- While loops
- Print and read bytes
Mindfck is written in go.
Build
go build .
Run
go run .
Tests
go test ./...
Grammar is written in antlr4 (parser/mindfck.g4). If it is updated, files need to be regenerated.
Install antlr4-tools to work with the parser
pip3 install antlr4-tools
You'll also need java-11-jre or openjdk-11-jre installed
To regenerate the parser, do:
go generate
This will execute antlr4, equivalent to: antlr4 parser/antlr/mindfck.g4 -Dlanguage=Go
To parse something manually in the command line:
antlr4-parse parser/antlr/mindfck.g4 statements -gui
