A scanner is a program that takes a sequence of characters (the source file of the program) and produces a sequence of tokens that will be used to feed the compiler's parser.
A file called "input.txt" contains the raw code. Also, this file is in the same directory as compiler.py.
A parser is a compiler or interpreter component that breaks data into smaller elements for easy translation into another language. In this project we implemented a recursive descent parser.A recursive descent parser is a kind of top-down parser built from a set of mutually recursive procedures (or a non-recursive equivalent) where each such procedure implements one of the nonterminals of the grammar.
-
parse tree
-
panic mode
Generate intermediate code which is relatively close to assembly language.
- handle recursive functions
pip install -r requirements.txt
make run
Put output.txt file in interpreter directory and run ./tester_<YOUR_OPERATING_SYSTEM>
For program to create symbol_table, lexical_errors, syntax_errors and parse_tree in the path tools/Development.py set develop_mode = True.
