Decimal Integer List Encoding

See more Encryption Examples

The "decList" encoding was added in Chilkat v9.5.0.66 to encode and decode binary bytes from comma-separated decimal integers. Zig

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

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

    // Note: This example requires Chilkat v9.5.0.66 or greater.

    const byte_vals = "84,104,101,32,116,114,117,101,32,115,105,103,110,32,111,102,32,105,110,116,101,108,108,105,103,101,110,99,101,32,105,115,32,110,111,116,32,107,110,111,119,108,101,100,103,101,32,98,117,116,32,105,109,97,103,105,110,97,116,105,111,110,46";

    // Demonstrate encoding/decoding comma-separated decimal integrs to/from binary.
    const bin_data = try chilkat.BinData.init();
    defer bin_data.deinit();
    bin_data.appendEncoded(byte_vals, "decList") catch {};

    // Examine the data in hex
    std.debug.print("HEX: {s}\n", .{try bin_data.getEncoded(alloc, "hex")});

    // Decode to a StringBuilder
    const sb = try chilkat.StringBuilder.init();
    defer sb.deinit();
    sb.appendBd(bin_data, "us-ascii", 0, 0) catch {};

    // The bytes were actually the us-ascii char values for the string
    // "The true sign of intelligence is not knowledge but imagination."
    std.debug.print("{s}\n", .{try sb.getAsString(alloc)});

    // Now get the bytes in decimal list format again:
    std.debug.print("{s}\n", .{try bin_data.getEncoded(alloc, "decList")});

    // The output of this example is:
    // HEX: 5468652074727565207369676E206F6620696E74656C6C6967656E6365206973206E6F74206B6E6F776C656467652062757420696D6167696E6174696F6E2E
    // The true sign of intelligence is not knowledge but imagination.
    // 84,104,101,32,116,114,117,101,32,115,105,103,110,32,111,102,32,105,110,116,101,108,108,105,103,101,110,99,101,32,105,115,32,110,111,116,32,107,110,111,119,108,101,100,103,101,32,98,117,116,32,105,109,97,103,105,110,97,116,105,111,110,46
