"xyzsh" shell script language

What is this software?

    a shell script language under linux, OSX, cygwin, and FreeBSD.

    > ls -F
    docs/ main.c samples/ sub.c
        
    > ls | each ( | chomp | -d && | print )
    docs
    samples

    > ls -F | grep -v /
    main.c sub.c

    > ls | each ( ! | chomp | -d && | print )
    main.c sub.c

    > ls | each ( | printf "-+- %s -+-"\n ) | join " "
    -+- docs -+- -+- main -+- -+- samples -+- -+- sub.c -+-

    > ls | each ( | scan . | join " " )

    > cat data
    Gorou Yamanaka
    Rei Tanaka

    > cat data | each ( | =~ Yamanaka && | print )
    Gorou Yamanaka

    > cat data | lines 0 1
    Gorou Yamanaka
    Rei Tanaka
        
    > cat data | each ( | split | lines 1 0 | join )
    Yamanaka Gorou
    Tanaka Rei
    Shiratori Yumiko
        
    > vim student.xyzsh
    class Student ( 
        | var first_name second_name age country
        
        def show (
            var first_name second_name age country | printf "name: %s %s?nage: %s?ncountry: %s?n"
        )
    )
        
    object student
    student::run ( print "Yamanaka Gorou 23 Japan" | split | Student )
        
    > load student.xyzsh
    > student::show
    name: Yamanaka Gorou
    age: 23
    country: Japan

Compiled and tested xyzsh below Operating systems
    OSX 10.8.0
    FreeBSD 7.1-RELEASE-p16
    CentOS 5.8
    Oracle Solaris 11 Express

AUTHORS
    I am a Japanese and an English learner. I'm so sorry for my strange English and please allow me to write such a English. I'll correct this step by step with my understanding English.

ATTENSION
    Use this software on your own risk. Don't use this under importnat systems. I recommend that you use this on your personal systems. I can't take a responsibility on your works with xyzsh. And use this with understanding that this language is not high performance.

How to compile
    Before compiling xyzsh, you need to resolve dependencies below. You need development packages.(ex. ncurses-devel or libncurse-dev)

    gcc 
    GNU make
    libc
    libm 
    ncurses(w)
    readline
    oniguruma (which is a regex library)
    iconv

    Have you installed above libraries? You can type below commands to compile xyzsh.

    ./configure --with-optimize
    make
    sudo make install

    or

    ./configure --with-optimize
    make
    su
    make install
    exit

    Default prefix is /use/local/bin, so you need a root comission for make install.

    If you want to change an installed directory, type below

    ./configure --prefix=??? --with-optimize
    make
    sudo make install

    or

    ./configure --with-optimize
    make
    sudo make DESTDIR=??? install

    When you choise normal install, installed xyzsh to /usr/local/bin and setting files to /usr/local/etc/xyzsh.

    configure options are below.

    --prefix --> indicate installed directory. If you use --prefix=$HOME, xyzsh will be installed $HOME/bin, $HOME/etc. As default, prefix is /usr/local.
    --with-optimize --> compiled with optimize. Fast binary will be made.
    --with-onig-dir --> indicate oniguruma installed directory.
    --with-readline-dir --> indicate readline installed directory.
    --with-debug --> give -g option to CFLAGS and add a checking memory leak system to xyzsh.
    --with-gprof-debug --> give -pg option to CFLAGS
    --with-static --> make xyzsh without dynamic linked libraries.

    For Japanese options

    --with-migemo --> enable migemo_match inner command for Japanse
    --with-migemo-dir --> indicate migemo installed directory.
    --with-system-migemodir --> specify the directory of system migemo dictionary.

    xyzsh makes library, so add /usr/local/lib(or your installed directory)  to /etc/ld.so.conf and type below to refresh dynamic loarding searched path cache.
    
    sudo ldconfig
    
    or

    su
    ldconfig
    exit
    

    If you don't have root comission, add the path to LD_LIBRARY_PATH environment variable. (With OSX, you should use DYLD_LIBRARY_PATH_FALLBACK environment variable.)

with OS X
    Before you installed xyzsh, you should compile the readline library because OSX's readline is libedit, xyzsh needs GNU readline.
    Also you can use Macports or other compling system instead of manually compiling to install GNU readline.

Used files
    /usr/local/bin/xyzsh --> a program
    /usr/local/share/doc/xyzsh/USAGE --> USAGE in English
    /usr/local/share/doc/xyzsh/USAGE.ja --> USAGE in Japanese

    /usr/local/etc/xyzsh/help.xyzsh --> a source help setting file
    /usr/local/etc/xyzsh/read_history.xyzsh --> a source which reads command line history
    /usr/local/lib/xyzsh/*.so --> xyzsh C extension library
    ~/.xyzsh/xyzsh.xyzsh --> a source user setting file. xyzsh read this after /usr/local/etc/xyzsh.xyzsh
    ~/.xyzsh/history --> a command line history file
    ~/.xyzsh/macro --> macro which is runned by typing C-x on command line uses this file
    ~/.xyzsh/jump --> jump inner command uses this file
    ~/.xyzsh/menu --> menu inner command uses this file
    ~/.xyzsh/program --> program list which is entried to root object
    ~/.xyzsh/lib/*.so --> xyzsh C extension library for user

Encoding and Line field
    xyzsh script source file must be written with UTF-8 encode and LF Linefield. But, xyzsh can treat UTF8, EUCJP, and SJIS encodings and can treat LF, CR, LFCR line fields. (EUCJP and SJIS are for Japanese)
    You should run xyzsh as interactive shell on UTF-8 terminal.

Usage
    Type

    > ./xyzsh

    to use as interactive shell

    or

    > ./xyzsh -c "command"

    to run the command

    or

    > ./xyzsh (script file name)

    to run the script file
