}

Results were pretty same.

Код:

[15:55:34] strfind1 took 28715 
[15:56:03] strfind took 28718

So it would be useless only to use mine strfind seeing very little difference.

You used strfind1 twice.. lol..

Also, yours doesn't work properly. It returns 1 if found at 0, etc. It should return -1 if not found, 0 if at 0, 1 if at 1, etc..

woaw!

I will head over to Slice's reaction upon this.

EDIT: was late -.-"

Oh god never saw that I used strfind1 twice.

I made it return a greater value because my teacher told me that I should show location of char in the string.

Like if str is abc ,a=1,b=2 and so on.

I redid test and strfind is actually wayyy faster.

Strswap to swap 2 strings given that they have the memory needed

pawn Код:

stock strswap(s1[],s2[])
{
    new g=0;
    if(strlen(s1) > strlen(s2)) g = 1;
    if(strlen(s2) > strlen(s1)) g = 2;
    
    switch(g)
    {
        case 0:
        {
            for(new i=0;s1[i]!='\0';++i)
            {
                new temp = s1[i];
                s1[i] = s2[i];
                s2[i] = temp;
            }
        }
        case 1:
        {
            for(new i=0;s1[i]!='\0';++i)
            {
                new temp = s1[i];
                s1[i] = s2[i];
                s2[i] = temp;
            }
        }
        case 2:
        {
            for(new i=0;s2[i]!='\0';++i)
            {
                new temp = s1[i];
                s1[i] = s2[i];
                s2[i] = temp;
            }
        }
    }
    return 1;
}

Example

pawn Код:

new a[10] = "Money";
new b[] = "Goods";

printf("Before swap, buyer has %s and seller have %s",a,b);
strswap(a,b);
printf("After swap, buyer has %s and seller have %s",a,b);

Result :

Код:

Before swap, buyer has money and seller has goods
 After swap, buyer has goods and seller has money

PS : I need example how to use strfromliteral and strtoliteral

Re: strlib - String functions! - Slice - 03.08.2012

Copying strings can be done a lot faster using strcat, strpack, strunpack, or memcpy.

strtoliteral:

pawn Код:

new string[128] = "hello\nworld!\t\t\"abc\"";

strtoliteral(string, string);

print(string);

strfromliteral(string, string);

print(string);

Output:

Код:

"hello\nworld!\t\t\"abc\""
hello
world!		"abc"

Re: strlib - String functions! - [MM]RoXoR[FS] - 03.08.2012

So strtoliteral just escapes the \n \t and other literals?

Re: strlib - String functions! - Bakr - 03.08.2012

http://en.wikipedia.org/wiki/String_literal

A string literal is practically the string you type in the source code.

Re: strlib - String functions! - Slice - 04.08.2012

Update
All string functions now have similar functions with the same names, prefixed by "ret_".

pawn Код:

ret_strcatmid(string[], source[], start = 0, end = -1)
ret_strfrombin(input[], inputlength = sizeof(input))
ret_strimplode(glue[], ...)
ret_strreplace(string[], search[], replacement[], ignorecase = false, pos = 0, limit = -1)
ret_strfromliteral(input[], &pos = 0)
ret_strtoliteral(input[])
ret_strtrim(string[], chars[] = "", trim_edges:edges = trim_both)
ret_strurldecode(input[])
ret_strurlencode(input[], pack = false)
ret_strpack(source[])
ret_strunpack(source[])
ret_strcat(string1[], string2[])
ret_strmid(source[], start, end)
ret_strins(string[], substr[], pos)
ret_strdel(string[], start, end)
ret_valstr(value, pack = false)
ret_GetPlayerName(playerid, pack = false)

You can now do things like this:

pawn Код:

print(
    ret_strtoliteral(
        ret_strimplode(
            " ~ ",
            ret_strtrim(ret_strfromliteral("\"  hello   \"")),
            ret_strtrim("yyworldxx", "xy")
        )
    )
);

Output:

Код:

"hello ~ world"

The size of strings returned is determined by the constant "STRLIB_RETURN_SIZE" (default value: 12

.

If you know you won't need that much, you can change this by defining STRLIB_RETURN_SIZE before including strlib:

pawn Код:

#define STRLIB_RETURN_SIZE 64
#include <strlib>

Re: strlib - String functions! - milanosie - 08.08.2012

I get this error, any idea?

pawn Код:

C:\Users\Milan\Downloads\pawno\pawno\include\strlib.inc(154) : error 025: function heading differs from prototype

which is line forward

pawn Код:

strreplace(string[], const search[], const replacement[], bool:ignorecase = false, pos = 0, limit = -1, maxlength = sizeof(string));

Re: strlib - String functions! - Slice - 08.08.2012

Do you have a "strreplace" function already?

Re: strlib - String functions! - ReVo_ - 08.08.2012

Hi
When i use this include console says this error:

Код:

[21:17:01]    Error: Function not registered: 'OnVehiclePaintjob'

Re: strlib - String functions! - Slice - 09.08.2012

That's.. weird. What other includes, plugins, etc. do you use?

Re: strlib - String functions! - Ballu Miaa - 24.08.2012

DAMN GOOD WORK. Loved sprintf function.

Re: strlib - String functions! - MicroD - 24.08.2012

I really like this include, because it is very simple to use and you can easily manipulate with string.
I especially like strtoliteral and sprintf.

Re: strlib - String functions! - Drake1994 - 27.08.2012

strcount will an infinity loop, here is the fix:

Код:

stock
	strcount(const text[], const find[], bool:ignorecase = false)
{
	new
		pos = 0 - strlen(find),
		found = 0;
	
	while(-1 != (pos = strfind(text, find, ignorecase, pos + strlen(find))))
		found++;
		
	return found;
}

}

Thanks. I made something similar to yours. strcount now has an additional parameter called "count_overlapped":

pawn Код:

printf("%d", strcount("abcabcabc", "abcabc"));
// output: 1
printf("%d", strcount("abcabcabc", "abcabc", .count_overlapped = true));
// output: 2

As you can see, by default it will not count strings that overlap (this is the most common default behavior).
