EPUB checker option "--version" issue about epubcheck HOT 4 OPEN

The EPUB validation has failed while using the option "--version" in the command line argument and getting the default message in the log file if there are any errors or warnings in the source EPUB file. The previous version 5.0.1 correctly indicated the error/warning with version details.

This is likely due to the change made in #1526. The --version option now prints the version and exits the command, which I believe is the common behavior for command line tools.

Do you need to print the EPUBCheck version number and the check messages at the same time?

Hi @rdeltour ,
Thanks for your kind support.

Yes, I need to print the EPUBCheck version number and the check messages at the same time.

@rdeltour
I'm in need of outputting the version info with the check messages either, but would propose to introduce a new CLI option for this, maybe "-i"/"--info", which will simply add the version info to the "normal" output, e.g.:

java -jar /epubcheck.jar -i xyz.epub

will then output:

EPUBCheck v5.1.0 abgeschlossen
Verwendung der EPUB 3.3 Prüfungen
ERROR(RSC-005): xyz.epub/OEBPS/content.opf(3,56): Validierungsfehler: package dcterms:modified meta element must occur exactly once

EPUBCheck mit Fehlern abgeschlossen
Meldungen: 0 Schwerwiegende Fehler / 1 Fehler / 0 Warnungen / 0 Informationen

To "--version":

java -jar /epubcheck.jar --version

now outputs this:

EPUBCheck v5.1.0
Meldungen: 0 Schwerwiegende Fehler / 0 Fehler / 0 Warnungen / 0 Informationen

EPUBCheck abgeschlossen

This is very misleading. Please reduce the output to the version info only and then exit:

EPUBCheck v5.1.0

Misleading, because in my workflow, which runs for a decade now, "--version" was always part of the CLI command to test my epubs, so it took me some time to realize that there were errors in the epub I was checking, even though epubcheck says there were none.

@rdeltour
I made some testing and

java -jar /epubcheck.jar --help

outputs the trailing check informations either:

[...]
Meldungen: 0 Schwerwiegende Fehler / 0 Fehler / 0 Warnungen / 0 Informationen

EPUBCheck abgeschlossen

This should be fixed!

For a workaround until this is fixed:

java -jar /epubcheck.jar --version -q
java -jar /epubcheck.jar --help -q

suppresses the misleading check informations at the end.
