displayid3's Issues

Complete recognization of ID3

Includes all versions of ID3v1

TCON tag does not understand ID3v1 genres

Currently the program only transfers the entire text body into a string, even though the TCON tag can contain numeric codes to refer to ID3v1 genres.

Display extended header information

And contain the information in the struct. Currently the program will be broken by extended headers.

Allow printheader() to print different levels of verbosity

Without command line options, it would be only be useful changing back and forth between compilations. It would be better with command line options, but it's still nice.

Make returned structs not static

Currently getframe and getheader return pointers to static structs. That means that there can only be one of each. I imagine some time someone is going to want to use more than one of these things at a time. Maybe I might want to fill an array with pointers to a file's full set of frames.

Rename tag_preserve and file_preserve struct members

The names are misleading when considered along with their numeric values. These should be changed to "tag_discard" or something similar; assuming 1 is "true" then this change would make the code a bit more readable. This is entirely an aesthetic choice.

Apply a license

GNU GPLv3

Properly handle text frame encodings

Implementation: for all text frames, just break down the data into a string. This should probably be contained in the struct itself, with a bit indicating regular or Unicode encoding.

Print data from all frame types

Add command line option parsing

Option ideas:

• Control print verbosity
• Display only a certain type of tag (Year, artist, etc)
• Display usage info (of course)

Implement a unit testing framework

The code is getting difficult to debug just by scattering print statements throughout. I need to get this done before the code base gets much bigger i.e. before I start making this software compatible with additional versions of ID3.

Format printed text better

Recognize all versions of ID3

The versions of ID3v2 should be easy. Adding capability for ID3v1 would be almost entirely new code, though there are a few features of ID3v2 which can optionally reference ID3v1 information, like the genre list.
