Pike 7.1 developer version
While still young, Pike matured over the last few years, and
development is co-ordinated by a team at Roxen Internet Software AB.
Pike is released under the GNU General Public License (GPL). It is, and
will continue to be, freely distributed. Briefly, this means that you are
free to use and modify the source code in any way you please, see the
file COPYING for details. Roxen Internet Software maintains the right
to the brand name and the copyright, guaranteeing that Pike will be
continuously developed and enhanced, and remain free software.
Pike is easily learned, and just as easily used to develop powerful
applications. Pike is designed to be useful and powerful. As the
syntax of Pike is similar to that of C, most programmers will find it
easy to use. As Pike is a high-level, interpreted and modular
object-oriented language, powerful applications can be rapidly
developed. Pike has evolved rather than been designed. The changes to
Pike that have been made have been guided by its users' needs. In
general, the better you get to know Pike, the more you will appreciate
it, from a users perspective.
Pike is just as suitable for intricate and large applications as for
creating use-once scripts. When needed, you can also write
Pike modules in C, to gain better performance or access C
libraries. This is transparent to the module's users; the modules
written in C and those written in Pike are accessed in exactly the
same way.
A list of pros and cons with Pike follows:
+ General Purpose Programming Language
+ Freely distributed under GPL
+ Interpreted - No compilation and linking needed to run code
+ Object Oriented - Straightforward and powerful object
orientation, including multiple inheritance
+ Modular - Extendible with modules written in C or Pike
+ Powerful - High-level language, concise code
+ Incremental - Allows on-the-fly modifications and recompilations
+ Source Code Available - To promote sharing of useful code
+ Portable - Platform independent and available on most flavors of Unix
At present the following platforms are supported:
Solaris 2.5.1 & up (Sun SPARC & Intel x86)
Tru64
AIX 4.3
IRIX 6.5
FreeBSD 4.0
HP-UX 10.20
Linux Red Hat 4.2, 5.2, 6.1 and others (Intel x86)
+ Powerful, Flexible and Efficient Data Types
+ Automatic Memory Management
+ Scalable - as useful for small scripts as for powerful and
complex applications.
+ Text Processing - e.g. for filtering
+ Exception Handling
+ Multi-Threaded Application Development Possible
How Pike relates to other programming languages:
+ Optimized - Faster run-times than Perl, Python, tcl and Java
+ Faster Development than using C or C++
+ C-like Syntax - Easy to learn
Below you will find a list of some desired but missing features, or
cons, of Pike. Pike is still under development and the goal is to
incorporate those in future versions.
- No Pike native compiler or debugger available
- Not optimal for heavy numeric processing jobs
- Limited range of special effect image filters for image
processing
Some successful applications using Pike include:
+ Network Applications - as Client/Server applications
e.g. the Roxen Challenger Server and a range of server extensions
Mail Gateways
Client/server Protocol Implementations
Multi-User-Dungeons
+ System Administration Tools & Utilities - Even as quick one-shots
e.g. adduser or adddomain scripts that setup users/domains
Real-time Client/Server Status Monitor
+ Assorted Text Processing Utilities
+ CGI Programs
Pike is distributed accompanied by a set of modules, some of which are
described below.
Image - Image Processing Module
The Image module lets you perform common image manipulation and
processing operations from Pike programs. The supported operations
include cutting and pasting, scaling, rotation, linear filtering of
most kinds, rendering text, etc. Anti-aliasing can be used when
performing any kind of drawing operation. Using the Image module, you
can automate jobs that would otherwise have required tedious work in
an interactive image processing program such as Adobe PhotoShop.
Sql - Interface to SQL Databases
The SQL interface makes it possible to use common SQL databases from
within your applications. It includes support for mSQL, MySQL, Postgres,
Oracle and ODBC.
MIME - Multimedia Internet Mail Extension Module
This module makes it easy to create and decode e-mail, including
attachments.
Gz - Data Compression Module
With this module you can compress data. Its name is slightly
misleading, as it uses ZLIB. ZLIB uses the same compression algorithm
as gzip, but the format for the compressed data is not compatible with
gzip.
Crypto - Cryptographic Toolkit
The crypto toolkit is a set of objects implementing various
cryptographic algorithms, as well as objects used to glue the other
objects together. The toolkit includes block ciphers AES, IDEA, DES
(including tripple DES) and CAST, the RC4 stream cipher, the hash
functions MD5 and SHA, and the public key cryptography algorithm
RSA. It also includes a some randomness sources.
The toolkit can be used for most kinds of cryptographic applications,
including encrypted network connections, as well as encryption of
files or other data.
