flactag.d

Pure D library for reading and writing FLAC tags. It is stable and fairly optimised, but it could do with a little clean-up.

Set-up

import flactag.flactag : FlacTag;
import flactag.objects : FlacTags, FlacPicture, FlacPictureType;

FlacTag flac = new FlacTag(`G:\track.flac`);

Opening a FLAC file. It is automatically closed when the FlacTag object goes out of scope.

Examples

Reading tags

FlacTags tags = flac.readTags();
string album = tags.getFirst("ALBUM");
string title = tags.getFirst("TITLE");

// FLAC allows multiple of the same field names.
string[] comments = tags.getAll("COMMENT");

Writing tags

FlacTags tags;
tags.set("ALBUM", "my album");
tags.setMany("COMMENT", ["com one", "com two"]);
flac.writeTags(tags);

Extracting pics

FlacTags tags = flac.readTags();
FlacPicture[] pics = tags.getAllPictures();
foreach (idx, pic; pics)
{
	auto fname = format("%02d.jpg", idx + 1);
 	pic.writeToFile(fname);
}

Writing a pic

FlacTags tags;
auto coverData = cast(ubyte[]) read("cover.jpg");

auto pic = FlacPicture(
	mimeType: "image/jpeg",
	type: FlacPictureType.FrontCover,
	data: coverData,
	description: "my desc"
);

tags.addPicture(pic);
flac.writeTags(tags);

Note

version(Windows)
{
	import core.sys.windows.windows : GetConsoleOutputCP, SetConsoleOutputCP;
}

version(Windows)
{
  auto ccp = GetConsoleOutputCP();
  SetConsoleOutputCP(65001);
  scope(exit) SetConsoleOutputCP(ccp);
}

D doesn't handle this so when printing Japanese/Korean etc tags on Windows in Command Prompt, you have to change your code page.

Disclaimer

flactag.d is stable, but you should still back up your tracks just in case.
