词法分析器

生成可执行文件

cd ava_lexer
mkdir build && cd build
cmake ..
make

demo 测试

cd demo
./ava_lexer regular_grammar.txt demo.ava

结果输出至控制台

cd demo
./ava_lexer regular_grammar.txt demo.ava -o

输出 DFA

cd demo
./ava_lexer regular_grammar.txt demo.ava -v

DFA 可视化

cd demo
./ava_lexer regular_grammar.txt demo.ava -v | python visual.py

• python 依赖

  pip install graphviz

语法分析器

生成可执行文件

cd ava_parser
mkdir build && cd build
cmake ..
make

demo 测试

cd demo
./ava_lexer regular_grammar.txt demo.ava
./ava_parser 2grammar.txt tokens.txt

输出中间过程和表

cd demo
./ava_lexer regular_grammar.txt demo.ava
./ava_parser 2grammar.txt tokens.txt -v
