An clean, interactive command line parser/menu for Java CLI.

Idealy, a Java CLI based app can be trigger by java -cp <class> <params>. But sometimes, a menu based configuration is useful and convinient. The interaction looks like:

 Wrong arguments: -g: [Invalid_value] Only 'Csv' is acceptable! 1) -g,--grammar []: Grammar name 2) -,--startRule [token]: Start rule of this parser -- R): refresh menu; X): exit Your input [# value]: 1 Http >! Only 'Csv' is acceptable! Your input [# value]: 1 Csv Your input [# value]: R 1) -g,--grammar [Csv]: Grammar name 2) -,--startRule [token]: Start rule of this parser -- R): refresh menu; X): exit Your input [# value]: x Back to main, let's continue.

Just try to run

• BeanBuilderSample.java (extract argument defintion via naming convention or Java Bean)
• BasicBuilderSample.java (set up argument definition via code)
• ChainedBuilderSample.java (set up argument via chained/multiple builders)

with input above.

This project is on the way and changes will happen any time without notification until it gets GA.
