C-INI-Parser

An simple INI parser based on inih in OOP style C99.

Preserve parsed INI data in hashtable and provide a key-value access interface.

// C API

// constructor
IniParserPtr_T IniParser_Create ( const char* const ini_filename );

// destructor
void IniParser_Destroy ( IniParserPtr_T P );

// check error
int16_t IniParser_CheckInstanceError ( IniParserPtr_T P );

// get string via key string
const char* const IniParser_GetString ( IniParserPtr_T P, const char* const section, const char* const name, const char* const default_value );

// get integer via key string
int32_t IniParser_GetInteger ( IniParserPtr_T P, const char* const section, const char* const name, long default_value );

// get real(double) via key string
double IniParser_GetDouble ( IniParserPtr_T P, const char* const section, const char* const name, double default_value );

// get boolean via key string
bool IniParser_GetBoolean ( IniParserPtr_T P, const char* const section, const char* const name, bool default_value );

// Example

Build from example folder via gcc (link iniparser.c and ini.c)

gcc -std=c99 -Wall -o test test.c ../src/iniparser.c ../src/internal/ini.c -I../src

Build via CMake

• DENABLE_EXAMPLE: build examples flag, default is TRUE.
• DENABLE_SHAREDLIB: share or static library flag, default is TRUE (shared).

mkdir build && cd build
cmake .. [-DENABLE_EXAMPLE=TRUE -DENABLE_SHAREDLIB=FALSE]
make
make install

Sample INI taken from inih repo

; Just comments
; Another comments

[protocol]             ; Protocol configuration, this is section
version=6              ; IPv6, this is name


[user]
name = Bob Smith       ; Spaces around '=' are stripped
email = bob@smith.com  ; And comments (like this) ignored
active = true          ; Test a boolean
pi = 3.14159           ; Test a floating point number

Sample Code

#include <stdio.h>
#include "iniparser.h"

int main(void)
{
    IniParserPtr_T p = IniParser_Create ("test.ini");
    printf ("Is error: %" PRId16 "\n", IniParser_CheckInstanceError(p));

    const char * v1 = IniParser_GetString (p, "user", "name", "taka");
    printf ("user-name: %s\n", v1);

    int32_t v2 = IniParser_GetInteger (p, "protocol", "version", 4);
    printf ("protocol-version: %" PRId32 "\n", v2);

    double v3 = IniParser_GetDouble (p, "user", "pi", 10.2);
    printf ("user-pi: %f\n", v3);

    bool v4 = IniParser_GetBoolean (p, "user", "active", false);
    printf ("user-active: %s\n", v4 ? "true" : "false");

    IniParser_Destroy(p);

    return 0;
}
