Title: No semicolon in output using diff with groupheadings (-g) on 2nd line.

ExifTool 13.12
Windows 11 pro

Hi Phil,
This may be intentional and for a good reason, but I dont understand it. Why is there no semicolon in front of '50.0 mm' in the first command, while it is present in the other 3?

No hurry, thanks in advance,
Frank

Note: I only noticed it while trying to parse the output for use in GUI, searching for the semicolon as separator for the tag name and the value. A 'normal human' would probably not notice it.

Code Select

C:\Foto\diff_Left>exiftool -s -g1 -FocalLength -diff _IGP0002.jpg _IGP0001.jpg
======== diff < _IGP0001.jpg > _IGP0002.jpg
---- ExifIFD ----
< FocalLength                     : 18.0 mm
>                                   50.0 mm
---- Pentax ----
< FocalLength                     : 18.0 mm
>                                   50.0 mm

C:\Foto\diff_Left>exiftool -s -G1 -FocalLength -diff _IGP0002.jpg _IGP0001.jpg
======== diff < _IGP0001.jpg > _IGP0002.jpg
< [ExifIFD]       FocalLength                     : 18.0 mm
>                                                 : 50.0 mm
< [Pentax]        FocalLength                     : 18.0 mm
>                                                 : 50.0 mm

Normal usage of -g1 or -G1:

Code Select

C:\Foto\diff_Left>exiftool -a -s -g1 -FocalLength _IGP0001.jpg
---- ExifIFD ----
FocalLength                     : 18.0 mm
---- Pentax ----
FocalLength                     : 18.0 mm

C:\Foto\diff_Left>exiftool -a -s -G1 -FocalLength _IGP0001.jpg
[ExifIFD]       FocalLength                     : 18.0 mm
[Pentax]        FocalLength                     : 18.0 mm

C:\Foto\diff_Left>

Hi Frank,

You mean colon, not semicolon.

Good spotting. This will be fixed in 13.13.

I'll add the missing colons in the -diff -g output.

You're fast!

My knowledge of the English language is not as good as I thought! I meant a colon.

Thanks,
Frank

Edit: Yes. Please keep the colon. For me it's better when I can be sure there's a colon in the output.
