Lisp Interpreter in Java (Source code attached)

I have written a Lisp Interpreter in Java, hope you'll like it.Feel free to contact me, once you run it, you'll know the my email address .Enjoy.how to run it?java -jar LispInterpreter.jaror use Makefilemake runmake run-1stpartmake run-evaloff etc ...how many lines of code?$ find -type f -name "*.java" | xargs cat | wc -l1663how do I write it?eclipse + git (github)which version of java?1.6what features does it have?if you know clisp, then it's pretty much the sameif you don't know clisp, well, learn lisp first.features:T NIL CAR CDR etc is supportedDEFUN is supported (well, what else do you want if defun is supported ?)Fault detection is quite goodMultiple switches for project: evaloff (default is on); listprintoff (default is on); lowercaseoff (default is on); lowercasesameoff (default is on)Makefile, README and design.txt tell you everything in detail.You can change it using eclipse or just command line, because makefile is readyis there bug?as far as I know, no critial bug. contact me if you find onesource code ?I have released the source code, I am no more interested in this project. You can get the latest copy (in case I've updated something in the future) by :$ git clone git://github.com/hdc1112/lisp_interpreter_in_javasome old screenshots, much has changed since then: README file:README for Lisp Interpreter in JavaDachuan [email protected]. how to use the interpreter? make (or make compile)::: to compile the whole program::: make sure that you do this after you modify the source code or there is not .class file in bin/make run ::: to run the interpreter ::: by default, eval is on && list printing is on && lower case letter is on && case insensitivemake run-1stpart ::: to run the interpreter in input&eval mode, and list printing is forbiddenmake run-evaloff-listprintoff::: to run the interpreter in input&eval mode, and list printing is forbiddenmake run-evaloff::: to run the interpreter in input&eval modemake jar::: to create a runnable jar filemake clean::: delete *.class and other trivial filesmake help::: if you need helpmake run XARGS="lowercaseoff" ::: forbid the lower case letters inputmake run XARGS="lowercasesameoff" ::: make this project case sensitive (built-in functions are still CAPITAL)!!!!!IMPORTANT!!!!! if your input is from file, you can do it in this way:(using pipe or redirection)cat test.txt | make run-1stpart   OR   make run-1stpart cat test.txt | make run        OR   make run DON'T DO IT IN THIS WAY:(THIS IS WRONG) make run-1stpart `cat test.txt` (THIS IS WRONG)2. what are the files in the project?the folder is a eclipse project folder, which means I developed it in eclipse, and you can import it to eclipseyou can also git clone this project:git clone git://github.com/hdc1112/lisp_interpreter_in_java.git.├── bin                *.class files will go here├── Makefile            makefile, you know├── manifest.txt        if you want a runnable jar file, you will probably need this├── README            that's me└── src                Source code folder    ├── Evaluate.java        Interpreter's 2nd component, Evaluator, it accepts a legal S-Exp    ├── Input.java        Interpreter's 1st component, Input, it reads a legal S-Exp from stdin    ├── LispBuiltin.java    Intrepreter's built-in functions' implementation    ├── LispInterpreter.java    Interpreter    ├── ***p.java        the Java class for S-Expression in Lisp    └── UnitTest.java        the test code, only for development purpose3.
