Your code will be syntax highlighted when you specify the language of your code with the BBcode code tag:
[code=lang] Your code here [/code]
where "lang" is the language of your code. For example, the following Perl code
#!/usr/bin/perl
print "Hello World!\n";
is rendered with:
[code=perl]
#!/usr/bin/perl
print "Hel...
The following are supported languages and their corresponding names for BBcode:
Apache conf: apacheconf, aconf, apache
Bash...
The full list is available from http://pygments.org/ , which is our backend engine for syntax highlight rendering.

MinGW is "Minimalist GNU for Windows" - a collection of freely available and freely distributable Windows specific header files and import libraries that allows you to build Windows native executables with GCC. MSYS is a minimal system that provides a POSIX compatible shell and utilities so that you can run the normal set of GNU build tools (such as configure, make). You can download MinGW and MSYS from sourceforge.net: http://sourceforge.net/project/showfiles.php?group_id=2435 . The set of files is overwhelming and installation is confusing sometimes. But here's what I did in order to build ffmpeg on Windows XP: Download "Automated MinGW Installer" (MinGW 5.1.4) Install MinGW 5.1.4. Select "Candidate". Check g++, but leave other options unchecked Finish installation of MinGW Install MSYS DTK 1.0 in C:\msys\1.0. Download "MSYS...

Syntax: qr/STRING/msixpo
For example:
$rex = qr/my.STRING/is;
s/$rex/foo/; ...
Since Perl may compile the pattern at the moment of execution of qr() operator, using qr() may have speed advantages in some situations, notably if the result of qr() is used standalone:
sub match {
my $patterns = shift;
...
Options are:
m Treat string as multiple lines.
s Treat s...

Python example:
def download_log(req, app = None, file = None):

Java example:

Whereas in Perl you initialize a hash like this:
%food_color = (
"Apple" => "red",
...
In Java, you usually do this:
Map<String, String> fruitColors = new HashMap<...
Using an initializer block you can make it more or less like the Perl syntax, although still not as clean:
Map<String, String> fruitColors = new HashMap<...
This may become handy when you pass a Map as a parameter to a method call and need to initialize the Map in place.
