Scripting in Delphi application [closed]

Question

i develop a BPM software and I would like to add end user scripting logic.

I try to express myself with an example.

in a Process there are 2 variables (Price, ApplyDiscount, DicountAmount, Total).

somehow the user wants to define this logic:

//Delphi code for explanation:
if ApplyDiscount then
  Total := Price * DiscountAmount
else
  Total := Price;

since my app is a SQL Server Client server app i thought also about the idea to run a query with parameters so the user uses SQL syntax to script the logic and it will work. I need to define the details but somehow the idea is to use the :Parameter syntax to allow the script pass and recieve values from my application.

This is for sure ok, but i was wondering if there is another way to do it without writing my scripting engine.

Thanks.

Answer 1

Some scripting engines for Delphi:

• DelphiWebScript which is my preferred: it has the best syntax, is probably the faster, and is Open Source;
• PascalScript;
• TMS Scripter Studio.

If you want "non pascalish" scripting, you can take a look at Lua which is pretty simple to work with.

Edit:

Some additional candidates:

• SEPI;
• ScriptEngineII;
• BESEN which is a JavaScript engine written in Delphi, including JIT!
• SpiderMonkey for Delphi also executing JavaScript.
