TOML in c99; v0.5.0 compliant.
Please see the toml.h file for details. What follows is a simple example that
parses this config file:
[server]
host = "www.example.com"
port = 80
For each config param, the code first extracts a raw value and then convert it to a string or integer depending on context.
FILE* fp;
toml_table_t* conf;
toml_table_t* server;
const char* raw;
char* host;
int64_t port;
char errbuf[200];
/* open file and parse */
if (0 == (fp = fopen(FNAME, "r"))) {
return handle_error();
}
conf = toml_parse_file(fp, errbuf, sizeof(errbuf));
fclose(fp);
if (0 == conf) {
return handle_error();
}
/* locate the [server] table */
if (0 == (server = toml_table_in(conf, "server"))) {
return handle_error();
}
/* extract host config value */
if (0 == (raw = toml_raw_in(server, "host"))) {
return handle_error();
}
if (toml_rtos(raw, &host)) {
return handle_error();
}
/* extract port config value */
if (0 == (raw = toml_raw_in(server, "port"))) {
return handle_error();
}
if (toml_rtoi(raw, &port)) {
return handle_error();
}
/* done with conf */
toml_free(conf);
/* use host and port */
do_work(host, port);
/* clean up */
free(host);
A normal make suffices. Alternately, you can also simply include the
toml.c and toml.h files in your project.
