xHarbour -> Harbour compatibility

[fraxzi]

Hi!

I wish to test my xHarbour+FWH8.12 to Harbour 1.0.1

problem is... I have GLOBAL and GLOBAL EXTERNAL declarations... massive like entirely on my .prgs'

question is... What can I do?


Regards,

[Ale SB]

I converts a system with my Xharbour to Harbour without any problem, but I used this harbour:

http://sourceforge.net/project/download ... p&65460143

because he thought more complete, the xHb.lib used to avoid conflicts in some statements to my xharbour.

It worked smoothly

Saluds, Ale

Hello Ale,

I tried to include xHB.lib but I still having errors on my GLOBAL..EXTERNAL variables

Using xMate compiling xHarbour App to Harbour 1.0.1:

Frances,

Try this define:

#define GLOBAL public

[fraxzi]

Frances,

Try this define:

#define GLOBAL public

Mr. Antonio,

Thank you for the suggestion and reply.

Public has to be inside procedure/function... I will just move my variable declarations into my init procedure...

But what about the GLOBAL EXTERNAL? would it be #define GLOBAL EXTERNAL public ?

Hi Mr. Frances:

I think you'll get the same efect with: #xtransalate GLOBAL EXTERNAL => Public

Sorry for the typo, I meant:
#xtranslate GLOBAL EXTERNAL => Public

[fraxzi]

Thank you so much Gurus Manuel and Antonio,

But after compilation.... I have tons of to do...

I need to abandon and going back to xHarbour where all apps are written...

sorry.

Kind regards,

Dear Mr.Fraxzi,

Can I ask you the reason for moving from xHarbour to Harbour.

Any advantage ? Or is it just for testing purpose

Mr. Anser,

Nice to hear from you again.

I dont mind answering.... well, I havent tried Harbour ever since I jumped to xHarbour...
I noticed that Harbour project is more active than xHarbour (based on release dates) so I just wonder what could be the experience and difference (?).

I guess I wouldn't know the advantage... But i'm still optimistic in converting/testing my apps with Harbour 1.0.1 or latest.

Manuel,

I think you'll get the same efect with: #xtranslate GLOBAL EXTERNAL => Public

I think, GLOBAL EXTERNAL must be replaced by MEMVAR, because you define a (GLOBAL) PUBLIC variable in the main module and then in all other modules using this variable, you have to decleare this variable as GLOBAL EXTERNAL or MEMVAR.

Code: Select all  Expand view

#xtranslate GLOBAL EXTERNAL => MEMVAR

[Antonio Linares]

Frances, Stefan,

yes, I agree too that you could use Stefan suggestion, to translate global external into memvar.

[xProgrammer]

Whilst it isn't a direct replacement in the sense that it isn't a matter of simply using an #xcommand or #xtranslate you can achieve the required outcome using a class to hold all your globals as member variables. I find this technique very useful.

You could use something along the following lines:

Code: Select all  Expand view

CLASS GlobalData

DATA ADSServer
DATA ADSLogin
...

METHOD New() CONSTRUCTOR

ENDCLASS

METHOD New() CLASS GlobalData

::ADSServer := 0
::ADSLogin := 0
...

RETURN self

Hello,

In old days , in clipper , global variables were simulated as :

In prog1

GLOBAL var1 change in STATIC Var1

# ifdef __XHARBOUR
GLOBAL Var1
# else
STATIC Var1
# endif

In prg1 we provide a function
# ifndef __XHARBOUR
FUNCTION Var1()
RETURN var1

Or
FUNCTION Var1(NewValue)
IF PCOUNT()>0
Var1 := NewValue
END
RETURN var1

# endif

In other modules

# ifdef __XHARBOUR
GLOBAL EXTERNAL Var1
# else
# xtranslate var1=>var1()
# endif
