Delphi FARR Plugin SDK updates? or working example?
« on: April 09, 2013, 06:54:51 PM »
Does anyone have a working example of a FARR plugin for Delphi?

There is a Delphi FARR Plugin example in the SDK but it doesn't work when compiled with Delphi XE2. The example is a few years old and might have been written before Delphi added unicode support.

Progress so far:

- I've created a Farr plugin DLL.
- The DLL is loaded by FARR when FARR starts.

The Farr plugin error log shows:

Quote
09:31 AM, Wednesday, April 10, 2013
 Error initializing plugin do_init function
C:\Program Files (x86)\FindAndRunRobot\Plugins\FarrPluginTest\FarrPluginTest.dll

The do_init() function exported by my DLL is not being called. I'm guessing the method signiture of my exported function is incorrect?

My do_init() function is declared using:
Quote
type
  Fp_GetStrVal = function(JrPluginPointerp:Pointer; varname:PAnsiChar; destbuf:PAnsiChar; maxlen:integer):BOOL; cdecl;
  Fp_SetStrVal = function(JrPluginPointerp:Pointer; varname:PAnsiChar; strbuf:PAnsiChar):BOOL; cdecl;

function PluginFunc_DoInit(
  const fullfilename:PAnsiChar ;
  inhostptr:Pointer;
  const hostname:PAnsiChar;
  const hostversionstring:PAnsiChar;
  incallbackfp_GetStrVal:FP_GetStrVal;
  incallbackfp_SetStrVal:FP_SetStrVal
): BOOL; cdecl;




Is there a way to have more detailed information added to the plugin error log?

let me upload for you a current working plugin so you can get the most recent header files and stuff.

Here's the source for a recent plugin made with C++ Builder, the sister to Delphi:
http://www.donationc.../PopQuotesSource.zip

It will have the most recent header files and functions wheras your delphi sample may be slightly old.

Thanks Mouser, taking a look now....

[some time later...]

From what I can see I've declared the PluginFunc_DoInit() correctly but I have very little experience translating C headers to Delphi so I could be wrong.

I've tried a few variations with no luck. My PluginFunc_DoInit() is never called when the DLL is loaded. The plugin error log reports the same error:

 Error initializing plugin do_init function
C:\Program Files (x86)\FindAndRunRobot\Plugins\test\FarrLocate32.dll

Any ideas?

Let me go look at the old delphi stuff and the new changes to the plugin headers and see if i can't spot any needed changes.

Can you send me your latest delphi code and i'll try compiling it and experimenting with it?

I've attached my plugin code. The plugin only exports one function, PluginFunc_DoInit().

I'm using Delphi XE2 to compile the plugin. The example plugin in the SDK doesn't work either when compiled with Delphi XE2.

Got it, and i'll have a look.

Since I haven't said it yet let me say it now: Thank you so much for your patience and cheerful spirit about this -- i don't think i would be so understanding if i was in your shoes -- if you don't give up I promise I will make sure you have a working delphi plugin framework for farr.

Thanks for taking a look mouser. I'm in well over my head when it comes to translating headers. (I don't know enough c)

Not at all!! FARR is a great utility that I'm slowly using more. Its usefulness will increase if I can write small plugins as well. You taking a look at the delphi SDK is much more then I expected!
