Simple single-header ini parser in c99
In just one c/c++ file do this:
#define INI_IMPLEMENTATION
#include "ini.h"In every other file you can simply include ini.h
-
merge_duplicate_tables:
By default, when there are multiple tables with the same name, the parser simply keeps adding to the tables list, it wastes memory but it is also much faster, especially for bigger files. if you want the parser to merge all the tables together use this option
-
override_duplicate_keys:
when adding keys, if a table has two same keys, the parser adds it to the table anyway, meaning that when it searches for the key with ini_get it will get the first one but it will still have both in table.values, to override this behaviour and only keep the last value use this option
-
key_value_divider:
the default key/value divider is '=', if you want to change it use this option
From file:
ini_t ini = ini_parse("file.ini", NULL);
char *name = ini_as_str(ini_get(ini_get_table(&ini, INI_ROOT), "name"), false);
initable_t *server = ini_get_table(&ini, "server");
int port = (int)ini_as_int(ini_get(server, "port"));
bool use_threads = ini_as_bool(ini_get(server, "use threads"));
ini_free(&ini);
free(name);From string:
const char *ini_str =
"name : web-server\n"
"[server]\n"
"port : 8080\n"
"ip : localhost\n"
"use threads : false";
ini_t ini = ini_parse_str(ini_str, &(iniopts_t){ .key_value_divider = ':' });
char *name = ini_as_str(ini_get(ini_get_table(&ini, INI_ROOT), "name"), false);
initable_t *server = ini_get_table(&ini, "server");
int port = (int)ini_as_int(ini_get(server, "port"));
bool use_threads = ini_as_bool(ini_get(server, "use threads"));
char ip[64];
int iplen = ini_to_str(ini_get(server, "ip"), ip, sizeof(ip), false);
if (iplen < 0) {
printf("(err) couldn't get ip: %s\n", ini_explain(iplen));
}
free(name);
ini_free(&ini);
