const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // First, for the purpose of understanding the structure of the MIME,
    // let's load the MIME into a Chilkat MIME object and examine the MIME structure.
    const mime = try chilkat.Mime.init();
    defer mime.deinit();

    try mime.loadMimeFile("qa_data/eml/TMobileTextMsg.eml");
    // Show the MIME structure in text format (as opposed to XML format).
    std.debug.print("{s}\n", .{try mime.getStructure(alloc, "text")});

    // The MIME structure for our test email looks like this:
    // multipart/related
    //     text/html
    //     text/plain
    //     image/gif
    //     image/gif
    //     image/gif

    // The HTML part is not considered a "related item" because the related items
    // are defined as being related to the HTML part.  Therefore, we should always
    // expect to find a text/html part under a multipart/related.  The HTML parts
    // is simply the HTML body, and the other parts are the related items.
    // If the text/plain part was to be considered as an alternative body,
    // then a properly structured email would include a multipart/alternative structure.
