# tomlc99
|
||
TOML in c99; v0.4.0 compliant.
|
||
|
||
|
||
# Usage
|
||
|
||
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"))) {
|
||
perror("fopen");
|
||
exit(1);
|
||
}
|
||
conf = toml_parse_file(fp, errbuf, sizeof(errbuf));
|
||
fclose(fp);
|
||
if (0 == conf) {
|
||
fprintf(stderr, "ERROR: %s\n", errbuf);
|
||
exit(1);
|
||
}
|
||
|
||
/* locate the [server] table */
|
||
if (0 == (server = toml_table_in(conf, "server"))) {
|
||
fprintf(stderr, "ERROR: missing [server]\n");
|
||
toml_free(conf);
|
||
exit(1);
|
||
}
|
||
|
||
/* extract host config value */
|
||
if (0 == (raw = toml_raw_in(server, "host"))) {
|
||
fprintf(stderr, "ERROR: missing 'host' in [server]\n");
|
||
toml_free(conf);
|
||
exit(1);
|
||
}
|
||
if (toml_rtos(raw, &host)) {
|
||
fprintf(stderr, "ERROR: bad value in 'host'\n");
|
||
toml_free(conf);
|
||
exit(1);
|
||
}
|
||
|
||
/* extract port config value */
|
||
if (0 == (raw = toml_raw_in(server, "port"))) {
|
||
fprintf(stderr, "ERROR: missing 'port' in [server]\n");
|
||
free(host);
|
||
toml_free(conf);
|
||
exit(1);
|
||
}
|
||
if (toml_rtoi(raw, &port)) {
|
||
fprintf(stderr, "ERROR: bad value in 'port'\n");
|
||
free(host);
|
||
toml_free(conf);
|
||
exit(1);
|
||
}
|
||
|
||
/* done with conf */
|
||
toml_free(conf);
|
||
|
||
/* use host and port */
|
||
do_work(host, port);
|
||
|
||
/* clean up */
|
||
free(host);
|
||
```
|
||

||
# Building
|
||
|
||
A normal *make* suffices. Alternately, you can also simply include the
|
||
`toml.c` and `toml.h` files in your project.
|
||
|
||
# Testing
|
||
|
||
To test against the standard test set provided by BurntSushi/toml-test:
|
||
|
||
```
|
||
% make
|
||
% cd test
|
||
% bash build.sh # do this once
|
||
% bash run.sh # this will run the test suite
|
||
```
|
