Install appdata files to /usr/share/metainfo

[sidt4]

$ apt-file search /usr/share/appdata/
gtimelog: /usr/share/appdata/gtimelog.appdata.xml

Notes:

• Use appstreamcli validate ( and not the deprecated appstream-util validate ) command to validate appstream metainfo files.
• The metainfo link above contains fallback appdata generated from .desktop file ( if the appdata in not installed in /usr/share/metainfo/ )

This should probably be reported to the Debian bug tracker. The upstream Makefile doesn't do anything with the appstream file, other than running appstream-util validate.

(I'll change it to use appstreamcli).

[mgedmin]

$ appstreamcli validate gtimelog.appdata.xml
E: ~:2: metainfo-ancient

This is not surprising, since I haven't touched the .appdata.xml since it was first contributed. Unfortunately the error message is also a bit terse.

I will try to force myself to read the relevant specs and see what needs to be changed. I have approximately zero motivation for this, so please do not expect a quick fix :(

$ appstreamcli validate --help
Usage:
  appstreamcli [OPTION…] - AppStream CLI.

AppStream command-line interface
 'validate' command

Help Options:
  -h, --help       Show help options

Application Options:
  --pedantic       Also show pedantic hints.
  --explain        Print detailed explanation for found issues.
  --no-net         Do not use network access.
  --strict         Fail validation if any issue is emitted that is not of pedantic severity.
  --format         Format of the generated report (valid values are 'text' and 'yaml').
  --override       Override the severities of selected issue tags.

--explain should give more explanation.

Recommended way is the following command:

$ appstreamcli validate --strict --explain --pedantic gtimelog.appdata.xml

Take your time.

Better appstream data will display the app properly in lots of software centers ( GNOME Software etc ).

IMHO make install should actually do that.

IMHO make install should actually do that.

I don't actually have a make install:

make: *** No rule to make target 'install'.  Pabaiga.

(that's also some amazing partial translation of the error message in GNU Make's lt_LT.po.)

[hfiguiere]

there should be one.
