hah, dunno why, but when one enters 'gfabasic' in google, it leads to my page

and then on to purebasic

see it as free advertising

just upped the page, wanna be sure that any straggler finds his way to purebasic

oh man, cannot wait for v4...

blueznl, just curious with what language have you written GfaBasic and if it's so lame, could you give the source?

you're gonna step on people's toes with this!

i DID NOT write gfabasic, if i did, i wouldn't be here

gfabasic was another basic variant from a few years back, and in fact it was not bad at all, it just sort of disappeared with the disappearence of the company that sold it

it had, however, a few very good points, and in some ways purebasic feels less structured than gfabasic did

then again, purebasic appears to be more powerfull, so i will not complain

if you want to try it, i think there are still some free demo versions floating on the net

Yep, GFA BASIC came out years ago for the Atari ST (originally). From Germany, it was brought to the US via Michtron software at a time when a good BASIC was needed to go beyond ST BASIC. GFA later appeared on the PC (Amiga too?). I still have some old Gfa-centric programming manuals laying around collecting dust. Ah the good 'old days.

GFA BASIC had competition from STOS/AMOS and BLITZ. Didn't Fred write a bunch of Blitz libs on the Amiga back then?

Hi,

I have been using GFA for about 100 years (maybe some less;) -- so I'd like to have some nice functions also in PureBasic (also in the editor, folding is just a begin, a real "auto complete", "auto indent" and "auto case" should be coming).

So I just began...

Hi Michael:
Welcome to PB!

For Auto Indent, you can try JapBE, a nice editor.

For PB4
viewtopic.php?t=19335&highlight=japbe

For PB3
http://gpihome.de/purebasic/jaPBe/

To call API functions from PB, append an underscore to the Api funcion name

Code: Select all

state=GetKeyState_(#VK_SHIFT)

Here goes the Dir procedure:

Code: Select all

Procedure.s DIR(); returns actual directory path, where program has been started from
  Buff$=Space(256) 
  GetCurrentDirectory_(256,@buff$)
  ProcedureReturn buff$;  get the directory information
EndProcedure

Debug dir()

BluezNL PB-GFA pages are a must.

Cheers!

GFA was on Amiga too, it was the first good BASIC on this platform (as I know, because Amigabasic was awful). But he hadn't any cool features like inline ASM and powerfull graphic functions, like the new BASICs, Amos, Blitz Basic and PureBasic.

Anyway, syntax was clearly defined, and the editor was not tolerant, so code was clean.

blueznl · Post by **blueznl** » Fri Feb 10, 2006 5:32 pm

well, isn't it time we wrote our own (unicode

) editor that does exactly that? check on code upon entering?

though it may not be easy

Post by **Fred** » Fri Feb 10, 2006 5:38 pm

Good luck

BleuZnL,

I hope you mean "we" write it in PureBasic?? Otherwise there are a lot of those editors. The onbly problem is that it will be sort of a "compiler" in it self.
Hence Fred's wink....

But the idea is a nice one, maybe a collaborate project? here on the forum? But why in (unicode) good old acsii not enough?

Jan V.

Personnally, I prefer to do code cleaning by myself, when I want it! Sorry to not support you in this idea...

blueznl · Post by **blueznl** » Fri Feb 10, 2006 9:14 pm

well, the basics would be simple, i mean, i do not want to write my own editor (but don't tempt me

) as i already have too many projects at hand

but what we could cook up is perhaps a procedure that would validate a line of code to see if it is correct purebasic syntax or not, from that point onwards we could either convince

the pb team to include our realtime syntax check in the ide (by, for example, letting the ide highlight a 'faulty' line in a different colour) or use it as a building block

i have, to be honest, no clue how difficult such a thing would be

it's great to be ignorant and naive
