If I were interested in adding some new commands to the PB language how would I go about doing it?

To clarify:
Do you mean adding new gadgets?
or
New command statements?
You could do either with a DLL I would think.

Look in the LibrarySDK folder of your PB install. There are documents and examples of how to create libraries with new commands and plugins for different image formats and gadgets / controls.

The easiest and simplest way i think is to write Macros with ASM inside and save it as PB include files.
Then, hop!, there are new custom commands for their use

Why with ASM inside?

Create a lib with regular PB code. (use ProcedureDLL for exported funcionts) and then use TailBite to make them a lib.
Look here for TailBite:

Something like this:
Code: Select all
ProcedureDLL MyNewCommand(param)
;do whatever you want
ProcedureReturn 1
EndProcedure

Because sure with ASM can be done the most powerful commands.

oh ok, sorry, I was trying to match with "easiest and simplest"

Actually, I was thinking more alone the lines of adding a new command that did something the current version of the language does not do. For example, a moviePlaying command that can be used with an .mp3 audio file that returns true if the movie is playing or false otherwise. Or a command that can be used to get the length (in seconds) of an .mp3 file (that does not contain frames).

In that case you are probably looking to create a lib. Take a look at the tailbite section of the forums. You can create a proc to do what you want and then use tailbite to create the lib and put it in a certain PB direction and PB will use it like it's own addins for database, linkedlists or whatever
atleast that's my understanding, I've never actually bothered to do it myself, I just create include files and add them when I need them

how to include the commands, you have some ways now - Includes, DLLs or UserLibs.
how to
program it, you'll have to learn some API-stuff and some ASM.
you have to know how to program it, if you want to include a command that returns the length of an mp3.
