Conca is
 - a concatenative programming language
 - an interpreter

Conca is a lot like Joy [ http://en.wikipedia.org/wiki/Joy_(programming_language) ]
but much smaller. It is also like Cat [ http://www.cat-language.com/ ].

The major difference is the definition of new functions.

Cat
        define square { dup * }

Joy
        square == dup *

Conca
        [ sup * ] "square" define

-------

Compile like this.

    csc timestamp.scm
    ./timestamp > prologue.scm
    csc -d1 -O3 -X numbers-syntax -deploy -prologue prologue.scm \
        -R numbers -R linenoise -o conca conca.scm


Actually, just use make like this.

    make    (on Linux)
    make    (on Windows with Cygwin)

-------

This program was built with Chicken Scheme 4.12.0 on Linux (Ubuntu) and
MS Windows 10 with Cygwin.

The libraries it needs are included.

Chicken Scheme

Cygwin

Build chicken Scheme like this

  make PLATFORM=linux PREFIX=/usr/local
  make PLATFORM=linux PREFIX=/usr/local check
  make PLATFORM=linux PREFIX=/usr/local install
  chicken-install numbers
  chicken-install linenoise

  make PLATFORM=cygwin PREFIX=/usr/local
  make PLATFORM=cygwin PREFIX=/usr/local check
  make PLATFORM=cygwin PREFIX=/usr/local install
  chicken-install numbers
  chicken-install linenoise
