Subject: [Circle] [CODE] File Viewer
The recent post of code snippets that had a function to view the
last 20 lines of the syslog really inspired me. I created a function
that allows people to view various log files. Gods can request how
many lines they want look at, etc. IMHO I think it makes a good code
snippet.
ACMD(do_file)
{
FILE *req_file;
int cur_line = 0,
num_lines = 0,
req_lines = 0,
i,
j;
int l;
char field[MAX_INPUT_LENGTH],
value[MAX_INPUT_LENGTH];
struct file_struct {
char *cmd;
char level;
char *file;
} fields[] = {
{ "none", LVL_IMPL, "Does Nothing" },
{ "bug",
LVL_IMPL, "../lib/misc/bugs"},
{ "typo",
LVL_BUILDER, "../lib/misc/typos"},
{ "ideas",
LVL_IMPL, "../lib/misc/ideas"},
{ "xnames",
LVL_IMPL, "../lib/misc/xnames"},
{ "levels", LVL_MINOR, "../log/levels" },
{ "rip", LVL_MINOR, "../log/rip" },
{ "players", LVL_MINOR, "../log/newplayers" },
{ "rentgone", LVL_MINOR, "../log/rentgone" },
{ "godcmds", LVL_IMPL, "../log/godcmds" },
{ "syslog", LVL_IMPL, "../syslog" },
{ "crash", LVL_IMPL, "../syslog.CRASH" },
{ "\n", 0, "\n" }
};
skip_spaces(&argument);
if (!*argument)
{
strcpy(buf, "USAGE: file <option> <num lines>\r\n\r\nFile options:\r\n");
for (j = 0, i = 1; fields[i].level; i++)
if (fields[i].level <= GET_LEVEL(ch))
sprintf(buf, "%s%-15s%s\r\n", buf, fields[i].cmd, fields[i].file);
send_to_char(buf, ch);
return;
}
strcpy(arg, two_arguments(argument, field, value));
for (l = 0; *(fields[l].cmd) != '\n'; l++)
if (!strncmp(field, fields[l].cmd, strlen(field)))
break;
if(*(fields[l].cmd) == '\n')
{
send_to_char("That is not a valid option!\r\n", ch);
return;
}
if (GET_LEVEL(ch) < fields[l].level)
{
send_to_char("You are not godly enough to view that file!\r\n", ch);
return;
}
if(!*value)
req_lines = 15; /* default is the last 15 lines */
else
req_lines = atoi(value);
/* open the requested file */
if (!(req_file=fopen(fields[l].file,"r")))
{
sprintf(buf2, "SYSERR: Error opening file %s using 'file' command.",
fields[l].file);
mudlog(buf2, BRF, LVL_IMPL, TRUE);
return;
}
/* count lines in requested file */
get_line(req_file,buf);
while (!feof(req_file))
{
num_lines++;
get_line(req_file,buf);
}
fclose(req_file);
/* Limit # of lines printed to # requested or # of lines in file or
150 lines */
if(req_lines > num_lines) req_lines = num_lines;
if(req_lines > 150) req_lines = 150;
/* close and re-open */
if (!(req_file=fopen(fields[l].file,"r")))
{
sprintf(buf2, "SYSERR: Error opening file %s using 'file' command.",
fields[l].file);
mudlog(buf2, BRF, LVL_IMPL, TRUE);
return;
}
buf2[0] = '\0';
/* and print the requested lines */
get_line(req_file,buf);
while (!feof(req_file))
{
cur_line++;
if(cur_line > (num_lines - req_lines))
{
sprintf(buf2,"%s%s\r\n",buf2, buf);
}
get_line(req_file,buf);
}
page_string(ch->desc, buf2, 1);
fclose(req_file);
}
