A plugin system in Ring: Easy.

[Mansour Ayouni]

Hello Mahmoud, Ilir, and All

I made a simple plugging system that extends a basic string class with an extended one, using the feature of Embedding Ring in Ring.

The programmer can enrich the string class with user-defined functions, written in a separate Ring file, conforming to a given convention.

Then, the plugin system dynamically loads the plugin files, and makes them callable from the extended string class using an Xf() function.

This exploration helped me define the strategy I'll use in Softanza V2 to provide it with a more lean and extensible design.

The main file (sample + implementation):

libraries/softanzalib/stzPlugginSystem.ring

Plugins files (should be hosted under "\plugins\" folder

libraries/softanzalib/plugins/plugin_string_reverse.ring

libraries/softanzalib/plugins/plugin_string_countVowels.ring

libraries/softanzalib/plugins/plugin_string_removeNonLetters.ring

libraries/softanzalib/plugins/plugin_string_replace.ring

Best,

Mansour

Hello Mansour

I understand this feeling, when we discover a nice feature we try to use it :D

But, there are many options to use before using Ring State functions

1 - Eval() function

2 - Load Package command (loading files in another global scope)

3 - The Call command (Function Pointers)

4 - Reflection and meta-programming (AddAttribute(), AddMethod(), etc.)

These options are too much better than Ring State functions in most cases

Because it uses less memory, faster, easy to debug

Also, it's tested very well in other projects like PWCT2

In General, I prefer using Ring State function only in particular situations like running Ring programs inside an IDE that works on Mobile or WebAssembly.

Greetings,

Hello Mahmoud,

I was thinking about those options too.

I'll make some experiments and let you know.

Best,
Mansour
