Regex2Graph

A Converter from Regex to DFA Graph(using graphviz-kotlin)

Initially be designed for helping me to complete my assignments of Principles of Compilation

Build

1. build using Gradle

./gradlew build

then you can use build/libs/Regex2Graph-fat-1.0-SNAPSHOT.jar directly.

Usage

java -jar build/libs/Regex2Graph-fat-1.0-SNAPSHOT.jar [-o <output svg filename>]

Then it can translate Regex from stdin to .svg file.

Limitations

1. Only 1 regex(in first line) can be process.
2. Doesn't have Syntax Check to Regex input.
3. Only Concat,Or,Brackets,Question mark and Kleene star can be process.
4. In output, it doesn't merge ranges, so the graph may be a little complicated.
