Build Instructions

Readme: To run the compiler either use the coderunner setup I already have and press the play button from the parser.y file which runs all the necessary files and takes the input txt called parser.txt.

OR : To run the compiler put these commands in the terminal and the text you want to compile in the parser.txt file:

fileName="parser.y"

dir=$(dirname "$fileName")

filename=$(basename "$fileName" .y)

flex -o del.yy.c "$filename".l

bison -d "$fileName

gcc -o "$filename".out del.yy.c "$filename".tab.c bucol.c table.c -lm

./"$filename".out < "$filename".txt
