     7  # Position Independent Source Code
     8  
     9  PISC is a stack-based programming language that is primarily inspired by factor, TCL, bash and a little bit of python, written in go. It's currently a study in how far one can take code quotations, polymorphic stacks and pervasive dynamism.

    11  ## Status
    12  
    13  PISC is currently not in active development. It has served it's purpose for me as a educational experience. That being said, it's a relatively small codebase, and I am more than happy to answer questions about it. Feel free to reach out on either mastodon (@yumaikas@mastodon.social), or at yumaikas94 on the googles mail service.

    23  Some examples (which you can try in [the playground][play]):

    25  <pre class="prettyprint">
    26  # String building
    27  ${ 
    28     "The answer is " 
    29     6 7 * >string 
    30     ", but we don't know the question" 
    31  }    
    32  
    33  /* Defining an adjustable fizzbuzz word */
    34  : fizzbuzz-n ( n -- ) :n /* Store from stack to n local */
    35      1 :i /* Store 1 into num variable */
    36       
    37      $n [
    38          $i 3 divisor? [ "Fizz" ] [ "" ] if :f
    39          $i 5 divisor? [ "Buzz" ] [ "" ] if :b
    40          $f $b str-concat :fb
    41          $fb len 0 > [ $fb println ] [ $i println ] if 
    42          ++i
    43      ] times ;

    50  # Installing From Source
    51  
    52  Before you can install PISC for trying out, you'll need to install [Go 1.9][go19] or newer.
    53  
    54  There are two ways to install PISC right now
    55  
    56  1) Install [fossil][fossil] and run    
    57      
    58      mkdir "$GOPATH/src/pisc" && cd "$GOPATH/src/pisc"
    59      fossil clone https://pisc.junglecoder.com/home/apps/fossil/PISC.fossil PISC.fossil
    60  
    61  2) Using git:
    62  
    63      mkdir "$GOPATH/src/pisc" && cd "$GOPATH/src/pisc" 
    64      git clone github.com/yumaikas/PISC-mirror .
    65  
    66  In the future, a different URL for PISC is planned, but has not been setup as yet.
    67  
    68  Once you have Go, and have PISC somewhere where the go compiler can work with it, you can run `go get` to fetch PISC's go dependencies, and `go build -o pisc` to build the PISC interpreter. 
    69  
    70  Once you have PISC built, `pisc -i` will open an interactive PISC session.
