FB-interpreter

FB-interpreter is logic-arithmetic interpreter with variable and string support, build with Flex and Bison.

Running with Docker

docker run -it ahbenmed/fbinterpreter <examples/input_1.txt>

Running manually

Prerequisites

• C++ compiler should be installed GNU Compiler

• C++ Boost library should be installed boost

Run

cd FB-interpreter/

Compiling and generating the executable (interpreter.tab.c, interpreter.tab.h and lex.yy.c are auto-generated files produced by Bison and Flex from interpreter.y and interpreter.l)

g++ src/interpreter.tab.c -o fb-interpreter

The example folder contains some input_files, to test an example, run :

fb-interpreter <examples/input_1.txt>

Scrots

Adding new features

• Flex : Fast Lexical Analyzer should be installed

• Bison : General-purpose parser generator should be installed

Generate interpreter.tab.h(is included in interpreter.l) and interpreter.tab.c

bison -d interpreter.y

Generate lex.yy.c (included in interpreter.y)

flex interpreter.l
