Convert any File to Base64 (and back)

Demonstrates how to get the contents of any file as a base64 string, and then write it back. Zig

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

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

    const bd = try chilkat.BinData.init();
    defer bd.deinit();

    // This example will load a PDF and return it as a base64 string.
    bd.loadFile("qa_data/pdf/helloWorld.pdf") catch {
        std.debug.print("Failed to load file.\n", .{});
        return;
    };

    const b64_str = try bd.getEncoded(alloc, "base64");
    std.debug.print("{s}\n", .{b64_str});

    // Now write the base64 string back to the binary PDF file:
    const bd2 = try chilkat.BinData.init();
    defer bd2.deinit();
    try bd2.appendEncoded(b64_str, "base64");
    try bd2.writeFile("qa_output/helloWorld.pdf");
