strtrunc

Truncates a string. If the string is longer than the max chars specified, the excess characters are removed and replaced with "...".

Example:

pawn Код:

new
    string[24];

strtrunc("This is a test string.", 10, string);
print(string);

Outputs:

pawn Код:

This is a ...

Areas of use:

• Tab list dialogs where you don't want to show the entire string in the column (especially if it's long).
• Places where long strings can't normally fit and need to be truncated.
• And lots more!

Function:

pawn Код:

strtrunc(const source[], chars, dest[], maxlength=sizeof(dest))
{
    if(strlen(source) > chars)
    {
        if(ispacked(source))
        {
            strmid(dest, source, 0, chars, maxlength);
        strcat(dest, "...", maxlength);
    }
    else
    {
        format(dest, maxlength, "%.*s...", chars, source);
    }
    }
    else
    {
        if(ispacked(source))
    {
        strpack(dest, source, maxlength);
        }
    else
    {
        strcat(((dest[0] = 0), dest), source, maxlength);
    }
    }
    
    return 1;
}

How you would normally do it without using the function:

pawn Код:

if(strlen(banReason) > 24) 
{
    format(string, sizeof(string), "%s\t%.24s...\t%s", username, banReason, date);
}
else 
{
    format(string, sizeof(string), "%s\t%s\t%s", username, banReason, date);
}

How it looks like with this function:

pawn Код:

new 
    truncatedReason[24];

strtrunc(banReason, 24, truncatedReason);

format(string, sizeof(string), "%s\t%s\t%s", username, truncatedReason, date);
