Designing a C like compiler

File Structure

• cmd - All commands. Must be run from root only
• grammar - Grammar rules and descriptions
• lexer - Lex file. Reads the input and writes the tokens to out/lex/<input filename>.tkl
• parser - Parser program files
• results - Parsing table, Transition graph, Graph visualization
• symbol table - Symbol table generating program and writes the tokens to out/symbol table/<input filename>.csv
• util - Utility Cpp program to prepare for read and write to files
• out - Output files from the lexer, parser, and symbol table

Run

• Use a bash like shell
• Run ./run.sh
• Individual commands may be run as ./cmd/<command>.sh

Individual Commands in "cmd" directory

• lex.sh - Must be supplied with a file to lex
• symboltable.sh - Must be supplied with a file to generate the symbol table
• parse.sh - Run the parser
• visualize.sh - Visualize the transition graph (saved in results/graph.svg)
