compiler_boilerplate's Introduction

Compiler boilerplate

This repo contains flex/bison basic tempalte to create interpreters/compilers. In order to demonstrate it - we can do simplified version of AWK which is using direct input or file input

Limitations

  • Currently byte code compilation is not implemented
  • Conditions execution order is not implemented
  • String literls are not implemented

Build

make gen
mkdir -p build && cd build && cmake ../ && cmake --build .

Simplified version

make all

Test run

make test

Some examples of code

$1 == 123 { $1 }
$1 == $2 { $1 }
$1 > $2 { $1 }
$1 >= 3 { $1 }
$1 > 3 && $2 == 1 {$1}
$1 > 3 || $2 == 1 {$1}
$1 == 4 { print($1, $2, $3) }
