Viewer should support hex mode for binary files

[radius75]

Related to #30

It depends on the file on which we are doing VIEW.
Shows fragments of text that is "under" the window.
I attach elv1.d64 on which it occurs.
Probably some symbol causes that the content of the window is not cleared with spaces in the text line.

elv1.zip

The viewer should switch to binary mode when it is not text. Then the problem is solved. Can you change the ticket title?

Then the problem is solved.

Now I updated u2+ to fw3.10f and it doesn't show binary values. I choose View on elv1.d64. It's the same as it was.
Did I misunderstand "solved"?

[GideonZ]

I didn't say it was solved. Someone else did. Was it you?

I understood that Solved means Fixed on master branch :)

No, the problem that you are seeing old data from the file browser will be solved, once / when the file viewer will support hex mode. It doesn't at this point. This is why I mentioned: change the ticket to: "Viewer should support hex mode for binary files."

I reopen the issue, my mistake.

I would also find this feature very useful as I noticed its absence frequently when browsing my file collection.

When displaying the hex content, it would be great to use the format used by many C64 machine code monitors such as SMON:

<16 bit offset from start of file, in hex> ' '
<8 bytes of file data in hex, each byte followed by a space> ' '
<same 8 bytes rendered as PETSCII or '.' if not printable>

Example:

0000 00 00 41 42 43 44 45 46    ..ABCDEF
0008 00 00 00 00 00 00 00 47    .......G

The benefit of not just showing hex code, but also PETSCII, is to have the best of both worlds in the same view, e.g. when trying to find text in binary files.

Btw, issue #151 is closely related to this and could be viewed as an extension. The hex viewer idea is mentioned there, as well.
