Bug#916312: valadoc: Should depend on gtk-doc-tools for the gtkdoc doclet

[Colomban Wendling]

Package: valadoc
Version: 0.30.0~git20160518-2
Severity: normal

Dear Maintainer,

I think valadoc should depend on gtk-doc-tools or at least recommend it.
Without it, using the gtkdoc doclet (--doclet gtkdoc) leads to a fatal
error:

gtkdoc-scan:  error: Failed to execute child process "gtkdoc-scan" (No such file or directory)

Installing the gtk-doc-tools package fixes the issue.

I would expect the various doclets to work out of the box after
installing the valadoc package, but in any case I believe recommending
the required packages which make the options work would make a lot of
sense.

Regards,
