Now StrLib has almost 20 functions, and they are described in source, so it is quite easy to miss some feature. In next release I will try to create some .txt file and put there description of all routines, and general information about StrLib.

AFAIK, now scientica works on help system, that will extract help information directly from the source. So there is not necessary to write separate docs.

Oh.... now I understand Smile

btw: one suggestion for the proc macros: maybe you could change them that they will not generate 'push ebp/mov ebp,esp' if function has no parameters nor local variables...

regards

I've uploaded current version of StrLib (with John's fixes). What's new:
- added two new low-level NumToStr routines: NumToStrF and NumToStrUF (by John Found)
- NumToStr was rewriten
- some bugfixes & modifications were done.
- added StrExtract

Actually it is not a new version, I just have done some bugfixes...

By now it doesn't use new set of macros (but it uses "if used" statements). I will add those macros in new version Smile.

regards,
Decard

That's version 1.1.4 of StrLib...
- library was rewtiten to use John Found's stdcall macros
- added two new low-level NumToStr routines: NumToStrF and NumToStrUF
- NumToStr rewriten
- some small bugfixes & modifications
- added StrExtract (it's a requested SubStr routine, but wanted all names in lib begin with 'Str', and StrSub didn't sound nice to me Very HappyVery Happy )

[EDIT]outdated attachment removed. Now StrLib can be found in Fresh Package.[/EDIT][/b]

Something has changed, and it causes me to get an "unexpected" output.

With verison 1.1.3 I get this out put:

but with version 1.1.4:

I'll run a diff on the strlib and see what has changed - it wouldn't suprise me if the error is in my code (using some bug/"un-doc-feature" to work). Does any other experiance somethig similar?

btw, yes the output is from harsyra, as you can see I'm using the strlib :)
the source is a mayham - still got remains of the old non-strlib code, which soon will "disappear".

I've really no idea what could cause this strange output Sad My small test routine works just fine... But I didn't test all of the routines that I've changed, maybe this could make it happen. Can you write more about the problem (which functions are you using, etc...)? I will try to test all routines in StrLib and see if something is wrong... Unfortunately I can't do it today as I have to learn for tomorrow's German test (Arghhhhh Mad)...

decard

I know, rember them, but luckily Swedish has some similarities with German (so I could guess the meaning of some germain words). Good luck Smile

With risc of this beeing to little, but these are what I've used (I've excluded a few calls which are basically the same as the listed). I haven't had time to check the code again (a few RL matters to tend to), but I'm about to take look now.
Code:
Functions from strlib.asm used by Harsyra.asm:
  call    InitStrings
  call    FreeStrings
  stdcall StrPos, esi, szFileComment ; search for ';<<<'...
  stdcall StrNew, [ebx+TFile.spName]
  stdcall StrCopy, eax, esi      ; copy/set the filename
  stdcall StrPtr, [ebx+TFile.spFile]
section '.data' data readable writeable
...
  StrTable TStrTable

It was a VERY stupid bug in StrLen Evil or Very Mad I wonder how could I miss it? I wasn't testing StrLen, but some other functions that use it... Now I'm suprised how they even worked...

Now it should work OK...

Hi.
This library handles dynamic strings - they can be dynamically resized during runtime.
The main idea for string handles instead of pointers is that handle remains constant, while the pointer may be changed when the string length is changed.
Of course, the most of StrLib functions work fine with static pointers as well.

You have to read "freshguide.chm" from Fresh package for more details. There is very good description of whole library by Decard.

Regards.

do you have a mid string function to take only part of a string (ie in the middle)
str1 db 'BlaH',0
strbuffer rb 0xF000
MIDSTR str1, 3, 2, strbuffer
strbuffer = 'a','H'

MIDSTR Mstr, Start, Len, Buffer
Mov ESI, Mstr
Mov EBX, Buffer
Add ESI, Start
Mov ECX, FFFFFFFFh
LBL1:
Inc ECX
Mov AL, byte[ESI+ECX]
Mov [EBX+ECX], AL
Cmp ECX, Len
JL LBL1

Something along those lines [pretty sure the above will NOT compile]

You could also have a look at my try for fasm standard library, there's currently 23 string functions if i counted them right. Including StrMid.

aaro your library is great, keep up the good work. Just skimming through it i've learned tons about assembler.

the most impressive part of it is the efficiency in the code. you squeezed every byte Very Happy
