Ciao guys,

yes, it's me again... I got a two, kind of lame questions...

1) What is the best way, how to determine if string is empty?

PHP Code:

// is empty option 1
if (StrEqual(sMyString, ""))

// is empty option 2
if (strlen(sMyString) == 0)

// is empty option 3
if (sMyString[0] == EOS) 


2) And how to make string empty properly?

PHP Code:

// make empty option 1
strcopy(sMyString, sizeof(sMyString), "");

// make empty option 2
sMyString[0] = EOS;

PHP Code:

strcopy(sMyString, sizeof(sMyString, "")); // typo
strcopy(sMyString, sizeof(sMyString), ""); 


where did you get that EOS ?

setting first cell to a zero-terminatin character is the fastest way.

my guess is, strcopy would clean the whole string.

you might also want to trim strings before checking.

Thx.

PHP Code:

EOF = end of file // not sure if it works in sp
EOL = end of line // not sure if it works in sp
EOS = end of stream // same as '\0' in sp

It depends on your purpose... personally I use

if (!sMyString[0])

which means string is empty.

And again to 'clean up' string you can use this

sMyString[0] = '\0'

This method will not be available with new syntax, but that's none of my business.

Where they're defined at?

I didn't find anything in the includes, but I found this.

EDIT: And EOL should by according to OS, linux = LF, win = CRLF

[friagram]

Just check if he cell is '\0' or whatever delim you are using

Please never, ever use that constant in a SourceMod plugin.

What makes you think that? The whole point of the type rename is to clarify them as being char arrays rather than first-class strings.
