compiler for python made using lex yacc /GNU's flex bison.

The current version of this code supportsdefining a function,defining a class,calling a function, various types ofexpressions,assignment statements, andif conditions, in addition to loops such asfor andwhile and some other structures such astry,match,yield,global,nonlocal,return,break,continue,INDENT \DEDENT analysis usingstack

You will needflex,bison, andgcc installed on your machine

$ chmod +x build.sh clear.sh

$ ./build.sh
compiled:compiler,parser.tab.c,parser.tab.h,lex.yy.c

$ ./compiler test.py

$ ./clear.sh

This program is run using the following commands:

bison -d parser.y

• This instruction produces two files:
  • parser.tab.h : We use this to include it inside the flex file to read the token
  • parser.tab.c : We use this file to make a compiler with the resulting flex file

flex pycompile.l

• This instruction produces lex.yy.c file: We use this file to make a compiler with the resulting bison file(parser.tab.c)

Finally, to compile flex and bixon, we write this command:

 gcc -o<program file name> parser.tab.c lex.yy.c

• This produces .exe file

Note : Thestack file is included in order to deal with indentation in a file pycompile.ltest file is : test py

but now is ready to execution ^_____^
