Command_Interpreter_SVG

This application uses unix lexers/parsers (FLEX and BISON) to read a .txt list of commands and draw them to a .svg file.

Usage

• Open Linux terminal, navigate to the application folder and run ./logo < <commands> > <draw>
  • <commands> Is the first file specified below. (You can use the star.txt file, included here!)
  • <draw> Any name you want, plus the .svg format.
• You can write your own commands, as shown below.

File format

• This program requires a command file
  • make "<var_name> <var_value> -> lets you attribute a number to a variable.
  • forward :<var_name> -> draws forward, given a variable.
  • fd :<var_name> -> draws forward, given a variable.
  • right :<var_name> -> rotate right (degrees), given a variable.
  • rt :<var_name> -> rotate right (degrees), given a variable.
  • repeat :<var_name> [<command> :<var_name> ...] -> repeat a command n times. Inside the brackets, you can rewrite any command, as many times as you want.

Compilation

• Compile via Linux make command
  • Use <make> to create the executable
  • Use <make clean> to clean the objects/parser files

Dependencies
