README

        
=== Psych - v.1.0.1 - README.txt ===

1. ABOUT

Psych is yet another interpreter for Urban Müller's Brainfuck programming

language.  Besides the standard features, Psych allows resizing of the data

array at runtime, noncanonical input for `,', output in the form of numbers

rather than characters, output of a portion of the data array on program

termination, and running code passed via the command line.  You can even use

the -h switch to print out a short summary of the Brainfuck commands if, say,

you just can't remember which is the input command & which is the output.

Psych was written by John T. Wodder II  and is

licensed under the GNU GPL, version 3.0 or later.  The source repository for

Psych can be found on Github at .

2. FILE LIST

COPYING - the GNU GPL v.3, under which Psych is licensed

Makefile - the makefile

README.txt - this file

psych.1 - the Psych manpage

psych.c - the source code for Psych

psych.pod - the Plain Old Documentation source for the manpage

3. COMPILING

In order to compile Psych properly, you will need a standard C compiler that is

at least partially C99-compliant (the Makefile assumes gcc) along with some

POSIX features (specifically, the getopt() function and, if you want

noncanonical input, the  routines).

There are three features of the program that are designed to be easily

reconfigurable at compile time.  The default size for the data array can be set

by redefining the ARRAY_SIZE macro on line 20, and the datatype of the array

cells can be set on line 21.  Additionally, if your machine does not have the

 routines, or if you simply want to disable the option of

noncanonical input, comment out or delete the definition of ALLOW_TERMIOS on

line 19.

To build the program, simply run `make' or `make psych' (the only difference is

that the former will also remake the manpage if the POD source has been

updated).  Note that, unlike fancier open source projects, there is no `make

install'; you'll have to move the executable & manpage to their destination

directories by hand.

4. VERSION HISTORY

2014 Mar 12 - v.1.1:

 - Version history started

 - Added -n switch

 - Eliminated -i switch; its behavior is now always in effect

 - The -a and -p switches now support hexadecimal & octal arguments and handle

   invalid arguments better.

 - If the -p switch is given an argument greater than the size of the data

   array, it will be clamped to the size of the array.
