[Bug] pdfjam ERROR: --outfile cannot be a directory when input is stdin

[Wikinaut]

I have no idea what the reason for this message is:

 pdfjam-pocketmod 8.pdf

Apparently it was necessary to add --outfile like in

pdfjam-pocketmod in.pdf --outfile out.pdf

Apparently it was necessary to add --outfile like in

pdfjam-pocketmod in.pdf --outfile out.pdf

@DavidFirth shouldn't it work without ? The documentation is silent about it.

[DavidFirth]

Which documentation are you referring to, there?

[Wikinaut]

pdfjam --help
pdfjam-pocketmod --help

Instead of printing

pdfjam ERROR: --outfile cannot be a directory when input is stdin

you could better say

pdfjam ERROR: --outfile cannot be a directory when input is stdin / or --outfile option is missing, please define an outfile.

[DavidFirth]

Thanks! That's a good suggestion, and I'll add it as "to do" (in pdfjam --- note that pdfjam-pocketmod is no longer part of pdfjam, and is no longer supported by me).

[Wikinaut]

Yes, I know.

There was seemingly now reason to require --outfile when input is /dev/stdin. One may just generate a name from it as in all other cases resulting in stdin-pdfjam.pdf by default.
