# esp-inih (INI Not Invented Here) [](https://github.com/leeebo/esp-inih/actions/workflows/tests.yml) **This is a ESP-IDF component warpped version of [inih](https://github.com/benhoyt/inih), which can be directly used in ESP-IDF projects.** **inih (INI Not Invented Here)** is a simple [.INI file](http://en.wikipedia.org/wiki/INI_file) parser written in C. It's only a couple of pages of code, and it was designed to be _small and simple_, so it's good for embedded systems. It's also more or less compatible with Python's [ConfigParser](http://docs.python.org/library/configparser.html) style of .INI files, including RFC 822-style multi-line syntax and `name: value` entries. To use it, just give `ini_parse()` an INI file, and it will call a callback for every `name=value` pair parsed, giving you strings for the section, name, and value. It's done this way ("SAX style") because it works well on low-memory embedded systems, but also because it makes for a KISS implementation. You can also call `ini_parse_file()` to parse directly from a `FILE*` object, `ini_parse_string()` to parse data from a string, or `ini_parse_stream()` to parse using a custom fgets-style reader function for custom I/O. ## Compile-time options You can using `idf.py menuconfig` to configure all the compile-time options. the options are is decribed in [compile-time-options](https://github.com/benhoyt/inih#compile-time-options) ## Simple example in C ```c #include <stdio.h> #include <stdlib.h> #include <string.h> #include "ini.h" typedef struct { int version; const char* name; const char* email; } configuration; static int handler(void* user, const char* section, const char* name, const char* value) { configuration* pconfig = (configuration*)user; #define MATCH(s, n) strcmp(section, s) == 0 && strcmp(name, n) == 0 if (MATCH("protocol", "version")) { pconfig->version = atoi(value); } else if (MATCH("user", "name")) { pconfig->name = strdup(value); } else if (MATCH("user", "email")) { pconfig->email = strdup(value); } else { return 0; /* unknown section/name, error */ } return 1; } void app_main(void) { configuration config; if (ini_parse("test.ini", handler, &config) < 0) { printf("Can't load 'test.ini'\n"); return 1; } printf("Config loaded from 'test.ini': version=%d, name=%s, email=%s\n", config.version, config.name, config.email); return 0; } ``` ## Related links * [inih (INI Not Invented Here)](https://github.com/benhoyt/inih)
