INI parser library

Usage example

Zig

pub fn main(init: std.process.Init) !void {
    const io = init.io;
    const file = try std.Io.Dir.cwd().openFile(io, "example.ini", .{});
    defer file.close(io);

    var read_buffer: [1024]u8 = undefined;
    var file_reader = file.reader(io, &read_buffer);
    var parser = ini.parse(init.gpa, &file_reader.interface, ";#");
    defer parser.deinit();

    var write_buffer: [1024]u8 = undefined;
    var file_writer = std.Io.File.stdout().writer(io, &write_buffer);
    const writer = &file_writer.interface;
    defer writer.flush() catch @panic("Could not flush to stdout");

    while (try parser.next()) |record| {
        switch (record) {
            .section => |heading| try writer.print("[{s}]\n", .{heading}),
            .property => |kv| try writer.print("{s} = {s}\n", .{ kv.key, kv.value }),
            .enumeration => |value| try writer.print("{s}\n", .{value}),
        }
    }
}```

### C

```c
#include <ini.h>

#include <stdio.h>
#include <stdbool.h>

int main() {
  FILE * f = fopen("example.ini", "r");
  if(!f)
    return 1;

  struct ini_Parser parser;
  char read_buffer[1024] = {0};
  ini_create_file(&parser, read_buffer, sizeof read_buffer, f, ";#", 2);

  struct ini_Record record;
  while(true)
  {
    enum ini_Error error = ini_next(&parser, &record);
    if(error != INI_SUCCESS)
      goto cleanup;

    switch(record.type) {
      case INI_RECORD_NUL: goto done;
      case INI_RECORD_SECTION:
        printf("[%s]\n", record.section);
        break;
      case INI_RECORD_PROPERTY:
        printf("%s = %s\n", record.property.key, record.property.value);
        break;
      case INI_RECORD_ENUMERATION:
        printf("%s\n", record.enumeration);
        break;
    }

  }
done:

cleanup:
  ini_destroy(&parser);
  fclose(f);
  return 0;
