Strip escape sequences when redirecting output to a file

[ghost]

I'd like to save my Kobo wishlist locally in a text file, for backup purposes.

I tried with:

python kobo-book-downloader wishlist > kobo-wishlist.txt

But if I open kobo-wishlist.txt with a text editor (emacs) I get the following output:

^[[1m1984^[[0m by George Orwell (ISBN: 9780547249643)
^[[1m2001: A Space Odyssey^[[0m by Arthur C. Clarke (ISBN: 9780748120789)
...

I could easily remove those escape sequences manually with a simple find & replace, but I wonder if kobo-book-downloader can detect if its output is being redirected to a file and, in that case, strip any escape sequence automatically.

What do you think?

I just found a nice program called ansifilter. Basically I can fix my problem with the following command:

python kobo-book-downloader wishlist | ansifilter > kobo-wishlist.txt

I could even keep escape sequences and generate an HTML document instead:

python kobo-book-downloader wishlist | ansifilter --html > kobo-wishlist.html

There was a missing call and that's why those sequences were not stripped.

I confirm that kobo-book-downloader now strips escape sequences correctly without the need of external programs like ansifilter.

Thank you!
