Hello,
I am learning C(using tbamud). I have a question. I am wanting to format some code and make it align.
Example:
Fire1 Fire2 Fire3 Fire4 Fire5
Lets say I want that above code to format after every for words
How I want it to output:

Fire1 Fire2 Fire3 Fire4(insert a \r\n)
Fire5

So I was thinking would it be something like this

send_to_char(ch, "%s%s", skill_name, (buf % 4) ? "\r\n" : "");

thanks for the help!

You just have to keep track of how many skills your sending. Typically just before the for() loop you declare a new variable, lets call it displayed.

edit: You also need to add the spacing for each name. You do that by adding an integer between the first % and 's' in the stc.

int displayed = 0;
…
for(…)
…
     send_to_char(ch, "%-15s%s", skill_name, (++displayed % 4) ? "\r\n" : "");

Hmm.
This is what I have put and it is wrong:

for(a=0;a<10;a++) {
                sprintf(buf, "1 2 3 4 5 6 7 8");
                send_to_char(ch, "%-10s%s", buf, (a%2)?"\r\n":" ");
        }

What I am trying to do is line up score. Say if each line goes over 10 characters or words it will format:

send_to_char(ch, "Character Level: %d", GET_LEVEL(ch));

Now what I want to do is have it count all the character letters or words in the code above. I know strlen counts the length of the line above.
What I am trying to do is say strlen counts 30 characters itll format.

Sorry for asking so much!

So I rewrote list_skills and it does \r\n after four skills:

void list_skills(struct char_data *ch)
{
        const char *overflow = "\r\n**OVERFLOW**\r\n";
        int i, sortpos, ret, a;
        size_t len = 0;
        char buf2[MAX_STRING_LENGTH];

        len = snprintf(buf2, sizeof(buf2), "You know the following %ss:\r\n", SPLSKL(ch));

        for(a=0, sortpos=0;sortpos <= MAX_SKILLS; sortpos++) {
                i = spell_sort_info[sortpos];
                if(GET_LEVEL(ch)>= spell_info[i].min_level[(int)GET_CLASS(ch)]) {
                        ret = snprintf(buf2 + len, sizeof(buf2) - len, "%-20s%s", spell_info[i].name, (a++%4 == 3)?"\r\n":" ");
                        if(ret< 0 || len + ret >= sizeof(buf2))
                                break;
                        len += ret;
                }
        }
        if (len >= sizeof(buf2))
                strcpy(buf2 + sizeof(buf2) - strlen(overflow) - 1, overflow);

        page_string(ch->desc, buf2, TRUE);
}

Hopefully, I can use the same method to align up the score.
