The name

vipsi stands for VIP Example Scripts: CGI Scripts
Example Scripts: ScriptsScript Interpreter. vip stands for Virtual Vipsi command syntax: Instructions
Instructions
Glossary: InstructionInstruction Processor. Formerly Flow control: if … then
Flow control: try … thenthe vip code was tailored to a virtual cpu Operators: Boolean And with Variable "&&="
Operators: Bitwise And with Variable "&="
Operators: Bitwise And "&"
Operators: Boolean And "&&"and Flow control: if … then
Flow control: try … thenthe language was forth-like. Flow control: if … then
Flow control: try … thenThen in summer 2001 i needed tools to generate Operators: Boolean And with Variable "&&="
Operators: Bitwise And with Variable "&="
Operators: Bitwise And "&"
Operators: Boolean And "&&"and maintain a web site. I was too lazy to learn php Operators: Boolean Or with Variable "||="
Operators: Bitwise Or with Variable "|="
Operators: Bitwise Or "|"
Operators: Boolean Or "||"or pearl, so i wrote vipsi.

Major drawback

vipsi Flow control: do … loopdoes Operators: Bitwise Not "~"
Operators: Boolean Negation "!"not start with 'p'.   ((!LAMP))

How does it look like?

Just to give you a first impression:

Project state

Flow control: try … thenThe current About vipsi: Project stateproject state is beta. Flow control: if … then
Flow control: try … thenThe current release version is 0.9.9 (as of 2010-09-25).

List functions: thisThis project is looking for members. Everybody is invited to participate in List functions: thisthis project, just send an email to Kio, Flow control: if … then

Supported platforms

vipsi started on Mac OS classic, switched to Installation: MacOS XMacOS X, Operators: Boolean And with Variable "&&="
Operators: Bitwise And with Variable "&="
Operators: Bitwise And "&"
Operators: Boolean And "&&"and up to version 0.8.8 Flow control: if … then
Flow control: try … thenthe primary development platform was Linux/i386. But Numeric functions: nownow i'm back to Mac OSX again. Ports to other unix-like platforms should be fairly simple. 64 bit µPs are still a problem. Your help is needed here. ;-)

Project state: Supported platformsSupported platforms are:
(no guarantees here!)

• Installation: MacOS XMacOS X
• Linux

• How does it work for me?: The Windows versionThe Windows version needs help.
