123 rows merged.145 rows merged.

Hello,
In Java I use this regular expression \b\w+\b as a pattern in order to find words but the boundary does not react to newlines. For example, in the following text:
hello and bye
and
blah
it finds the words below:
hello
byeandblah
and
Could someone tell how to fix that?... (1 Reply)

acme::brainfuck
Acme::Brainfuck(3) User Contributed Perl Documentation Acme::Brainfuck(3)NAME
Acme::Brainfuck - Embed Brainfuck in your perl code
SYNOPSIS
#!/usr/bin/env perl
use Acme::Brainfuck;
print 'Hello world!', chr ++++++++++. ;
DESCRIPTION
Brainfuck is about the tiniest Turing-complete programming language you can get. A language is Turing-complete if it can model the opera-
tions of a Turing machine--an abstract model of a computer defined by the British mathematician Alan Turing in 1936. A Turing machine con-
sists only of an endless sequence of memory cells and a pointer to one particular memory cell. Yet it is theoretically capable of perform-
ing any computation. With this module, you can embed Brainfuck instructions delimited by whitespace into your perl code. It will be trans-
lated into Perl as parsed. Brainfuck has just just 8 instructions (well more in this implementation, see "Extensions to ANSI Brainfuck"
below.) which are as follows
Instructions
+ Increment
Increase the value of the current memory cell by one.
- Decrement
Decrease the value of the current memory cell by one.
> Forward
Move the pointer to the next memory cell.
< Back
Move the pointer to the previous memory cell.
, Input
Read a byte from Standard Input and store it in the current memory cell.
. Output
Write the value of the current memory cell to standard output.
[ Loop
If the value of the current memory cell is 0, continue to the cell after the next ']'.
] Next
Go back to the last previous '['.
Extensions to ANSI Brainfuck
This implementation has extra instructions available. In order to avoid such terrible bloat, they are only available if you use the ver-
bose pragma like so:
use Acme::Brainfuck qw/verbose/;
The extra instructions are:
~ Reset
Resets the pointer to the first memory cell and clear all memory cells.
# Peek
Prints the values of the memory pointer and the current memory cell to STDERR. See also "Debugging" below.
Debugging
By using the debug pragma like this:
use Acme::Brainfuck qw/debug/;
you can dump out the generated perl code. (Caution: it is not pretty.) The key to understanding it is that the memory pointer is repre-
sented by $p, and the memory array by @m Therefore the value of the current memory cell is $m[$p].
RETURN VALUE
Each sequence of Brainfuck instructions becomes a Perl block and returns the value of the current memory cell.

print "We have liftoff!

Reverse
#!/usr/bin/env perl

while(1)
{
print "Say something to Backwards Man and then press enter: ";
+[->,----------]<
print 'Backwards Man says, "';
[+++++++++++.<]<
print "" to you too.
