lexer

🔢 java lexer

What it is

• Lexical analyzer for a subset of Java language.
• Syntax analyzer.
• Generator of the intermediate language by syntax tree.
• Generator of assembler code.

All modules are written in Java language. There is an ability to look the graphical view of syntax tree.

How it works

• Lexical analyzer works like a state machine, parses source code and generates the list of the tokens.
• Syntax analyzer is based on the Operator-precedence grammars. Tables for grammars are read from txt files. Syntax analyzer gets tokens and tries to make the syntax tree.
• Generator of the intermediate language constructs the flat list of tetrads by syntax tree.
• Generator of target code generates asm code by the tetrads.
