INI

INI module for V. It uses the ini.h library for parsing INI files.

Installation

$ v install --git https://github.com/houzhongjian/ini-beta

Loading an ini file and retrieving values

module main

import os
import doccaico.ini

fn main() {
    bytes := os.read_file('test.ini')!

    ini_data := ini.load(bytes.str, unsafe { nil })
    defer {
        ini.destroy(ini_data)
    }

    // global
    global_version_index := ini.find_property(ini_data, ini.global_section, 'Version'.str,
        0)
    global_version := ini.property_value(ini_data, ini.global_section, global_version_index)

    unsafe {
        println('Version=${cstring_to_vstring(global_version)}')
    }

    // normal section
    normal_section := ini.find_section(ini_data, 'Normal'.str, 0)
    normal_editor_index := ini.find_property(ini_data, normal_section, 'Editor'.str, 0)
    normal_editor := ini.property_value(ini_data, normal_section, normal_editor_index)

    unsafe {
        println('Editor=${cstring_to_vstring(normal_editor)}')
    }
    // Version=11.2401.26.0
    // Editor=c:/editor/vim.exe
}

Create a ini file

module main

import os
import doccaico.ini

fn main() {
    ini_data := ini.create(unsafe { nil })
    defer {
        ini.destroy(ini_data)
    }

    ini.property_add(ini_data, ini.global_section, 'Version'.str, 0, '11.2401.26.0'.str,
        0)
    ini.property_add(ini_data, ini.global_section, 'NoTrayIcon'.str, 0, '0'.str, 0)
    ini.property_add(ini_data, ini.global_section, 'Editor'.str, 0, 'c:/WINDOWS/system32/notepad.exe'.str,
        0)

    normal_section := ini.section_add(ini_data, 'Normal'.str, 0)
    ini.property_add(ini_data, normal_section, 'Version'.str, 0, '9.1'.str, 0)
    ini.property_add(ini_data, normal_section, 'NoTrayIcon'.str, 0, '5'.str, 0)
    ini.property_add(ini_data, normal_section, 'Editor'.str, 0, 'c:/editor/vim.exe'.str,
        0)

    needed_size := ini.save(ini_data, unsafe { nil }, 0) // Find the size needed
    data := unsafe { malloc(needed_size) }
    defer {
        unsafe { free(data) }
    }
    _ := ini.save(ini_data, data, needed_size) // Actually save the file

    unsafe {
        println('${cstring_to_vstring(data)}')
    }
    // Version=11.2401.26.0
    // NoTrayIcon=0
    // Editor=c:/WINDOWS/system32/notepad.exe
    //
    // [Normal]
    // Version=9.1
    // NoTrayIcon=5
    // Editor=c:/editor/vim.exe

    os.write_file('new.ini', unsafe { cstring_to_vstring(data) })!
}
