Running

# Run tests located in Programs directory
./test.sh 

# Run scanner on go string
printf "package main\n func main(){ println(\"Hello\")\n }" | ./golite scan

# Scan with the file
./golite scan < my_golite.go

# Parse
./golite parse < my_golite.go # outputs OK if the program is syntactically correct

# Symbol
./golite symbol < my_golite.go # outputs symbol table that is being built for the program

# Typecheck
./golite typecheck < my_golite.go # outputs ok if the program typechecks

# Codegen
./golite codegen generated_file_name < my_golite_to_tranlsate_from.go

Development

• I found that Emacs has the best support for writing C code. I wish I knew about this back in the time when I took operating systems.
  • Excellent tutorial on setting up Emacs for C
• valgrind very useful when debugging segfault errors. Just follow installation instructions from their website.
