System42, an anti-CMS for Phosphorus Five

WARNING - This module is deprecated, and no longer supported.

System42 is an example minimalistic "CMS" and use-case of Phosphorus Five. It also includes several helper components. The purpose of System42, is to provide a starting point, and example/reference implementation when developing Phosphorus Five applications.

Notice, if you install System42, it will completely override the default desktop, and entirely replace the default logic in Phosphorus Five, with its own URL resolver, and so on. Completely hiding the main P5 "operating system".

Notice also, System42 is a playground and example use-case, and not intended to be used in live production. It is not very mature unfortunately, since it was built simultaneously with Phosphorus Five, and is anyways considered way too much "bloat" to be used in real live production environments. However, as a simplistic use-case of what you can do with P5, it should probably be just about right.

System42, is also a "host" for your web apps, by allowing you to install your apps. To install an app into System42, is as simple as an x-copy operation, pasting your app into the "/modules/system42/apps/" folder, with optionally one file called "launch.hl", and another file called "startup.hl" - And your app should be ready for use.

The "startup.hl" file is evaluated when the server is started, and used for initializing your app, by creating supporting Active Events, etc. The "launch.hl" file, is expected to "launch" your app, whatever that means for your specific app. If your app has a "startup.hl" file, you'd probably want to evaluate this file after the x-copy operation.

The "components" folder works similarly, except it doesn't install an "app", but rather a "component", which might be either a visual widget, or a supporting Active Event, or anything in between.

Below you can find the two most important folders in the system.

  • Components which are the components in System42, such as Ajax TreeViews, Modal Windows, etc
  • Apps which are the preinstalled apps in System42, such as the "anti-CMS" and Hyperlambda Executor, etc

Installation, getting started

Make sure you put the system42 folder inside of your "/phosphorusfive/core/p5.webapp/modules/" folder, and make sure the System42 folder is called exactly "system42". Remove any additional parts of its name, such as versioning number, etc.

Restart your web server process, and you should be up running.

During the first startup of System42, you will be required to supply a server salt, and a root password. The salt is just a bunch of random characters used to salt your passwords, and seed the random number generator for cryptographic features. The root password should be difficult to guess, especially in live environments, that are exposed onto the world wide web.

Structure

The "application-startup.hl" file is evaluated when your application pool starts. This file creates a couple of helper Active Events, for evaluating Hyperlambda files, and folders. In addition, it evaluates all files in the "/modules/system42/startup/" folder.

When it is done with the above tasks, it will evaluate all "application specific" and "components specific" startup files. These are files inside of any "/modules/system42/apps//" and "/modules/system42/components//" folders, who's names are "startup.hl".

This allows you to create startup Hyperlambda scripts, both on system level, and on application/component level, that needs some sort of startup/initialization scripts, to be evaluated during startup.

The "apps" folder

This is the System42 version of your windows "C:/Program Files/" folder, and contains all apps in your System42 installation. See the documentation for the apps folder for details about this folder.

The "components" folder

This contains your components, which you can reuse in your apps. See the documentation for the components folder for details about this folder.

The "startup" folder

This folder contains files that are evaluated during application startup of your server, either because of your server rebooting, or because of the web-server process being restarted for some reasons. Normally you would want to either directly or indirectly create your global Active Events here, which multiple apps somehow are dependent upon.

Helper Active Events

Some of the more useful Active Events which you'll probably want to take advantage of in most of your applications, are listed below.

  • [sys42.utilities.execute-lambda-file] - Executes one or more Hyperlambda files
  • [sys42.utilities.execute-lambda-folder] - Executes all Hyperlambda files in a folder, recursively
  • [sys42.utilities.get-widget] - Returns all lambda associated with a widget, including events (reverse engineers a widget)
  • [sys42.utilities.empty-user-temp-folder] - Which empties a user's "temp" folder

System42 might also contain other supporting Active Events, depending upon which types of apps and/or components you have in your specific installation. In addition, System42 contains a web based Hyperlambda editor, built on top of CodeMirror, an HTML editor, built on top of CKEditor, and other things, that might help you out when creating your own apps. Including many helper widgets, such as Ajax TreeViews, Ajax TabControls, Ajax DataGrids, and so on. System42, also by default, includes jQuery and Bootstrap for your convenience.

System42 also contains a suite of Unit Tests, to test the integrity of Phosphorus Five. Which is highly extendible, such that you can create your own tests, and plug them into the existing suite.

You can’t perform that action at this time.
