How to write \n (newline) to a tag value?

[thomax]

exiftool.write('path/to/image.jpg', {'Copyright': 'Agent Smith\n1999'})

Fails with a message that the file named "1999" doesn't exist (Error: File not found - 1999). How can I use newlines in a tag? Any help appreciated :)

Thanks for the bug report!

TIL: ExifTool supports "HTML entity escaping". I've implemented this in version 7.4.0 which I just released.

Thanks to much, that was amazingly quick!

One question, if I may? Please excuse the noob factor, just trying to figure out how this fits together:

Say I want to write a string which includes newline character, would this be the correct code?

const ExifTool = require('exiftool-vendored').ExifTool
const exiftool = new ExifTool({exiftoolArgs: ['-E', '-stay_open', 'True', '-@', '-']}) // using -E in addition to the default args

exiftool.write('path/to/image.jpg', {'Copyright': 'going
going
gone'})
  .then(res => console.log('success', res))
  .catch(err => console.error('failure', err))

When I run the above code, and then read the written tag from the CLI:

> exiftool -Copyright path/to/image.jpg
Copyright                       : going
going
gone
> exiftool -Copyright path/to/image.jpg -b
going
going
gone%

The value of that tag is the literal string I just wrote, without newline characters. What am I missing?

[thomax]

Just to make sure it works in the CLI, I confirmed that the following works:

> exiftool -E "-Copyright=going
going
gone" path/to/image.jpg
> exiftool -Copyright path/to/image.jpg -b
going
going
gone%

(I've double-checked that I'm running [email protected])

I also tried this, without any more luck:

exiftool.write('path/to/image.jpg', {'Copyright': 'going
going
gone'}, ['-E'])

Ah. I've read your source code, followed the callstack and I now understand what's going on.

With v7.4.0, the -E arg is passed by default and therefore all string characters which are HTML-entity-candidates will automatically be encoded. Thus, when I used the literal string 
 in my tag and then called .write it was encoded into &#xa&#59; internally and then back to 
 when exiftool (the cli command) took over.

The solution was simpler than I thought. Just use the string \n instead of 
 :)

I will now be quite. Thanks for the rubber duck session 👍
