dLeyna updates and general project things

I have too many projects. That’s why I also picked up dLeyna which was laying around looking a bit unloved, smacked fixes, GUPnP 1.2 and meson support on top and made new releases. They are available at

  • https://github.com/phako/dleyna-core/archive/refs/tags/v0.7.0.tar.gz
  • https://github.com/phako/dleyna-connector-dbus/archive/refs/tags/v0.4.0.tar.gz
  • https://github.com/phako/dleyna-server/archive/refs/tags/v0.7.0.tar.gz
  • https://github.com/phako/dleyna-renderer/archive/refs/tags/v0.7.0.tar.gz

Furthermore I have filed an issue on upstream’s dLeyna-core component asking for the project to be transferred to GNOME infrastructure officially (https://github.com/intel/dleyna-core/issues/55).

As for all the other things I do. I was trying to write many versions of this blog post and each one sounded like an apology, which sounded wrong. Ever since I changed jobs in 2018 I’m much more involved in coding during my work-time again and that seems to suck my “mental code reservoir” dry, meaning I have very little motivation to spend much time on designing and adding features, limiting most of the work on Rygel, GUPnP and Shotwell to the bare minimum. And I don’t know how and when this might change.

Learning something new every day….

Just in case someone wonders what %~d0 in a .bat or .cmd file means, here’s the excerpt from help call:
[…]

In addition, expansion of batch script argument references (%0, %1, etc.) have been changed as follows:
%* in a batch script refers to all the arguments (e.g. %1 %2 %3 %4 %5 …)
Substitution of batch parameters (%n) has been enhanced.  You can
now use the following optional syntax:

%~1         – expands %1 removing any surrounding quotes (“)
%~f1        – expands %1 to a fully qualified path name
%~d1        – expands %1 to a drive letter only
%~p1        – expands %1 to a path only
%~n1        – expands %1 to a file name only
%~x1        – expands %1 to a file extension only
%~s1        – expanded path contains short names only
%~a1        – expands %1 to file attributes
%~t1        – expands %1 to date/time of file
%~z1        – expands %1 to size of file
%~$PATH:1   – searches the directories listed in the PATH
environment variable and expands %1 to the fully
qualified name of the first one found.  If the
environment variable name is not defined or the
file is not found by the search, then this
modifier expands to the empty string
The modifiers can be combined to get compound results:

%~dp1       – expands %1 to a drive letter and path only
%~nx1       – expands %1 to a file name and extension only
%~dp$PATH:1 – searches the directories listed in the PATH
environment variable for %1 and expands to the
qualified name of the first one found.  If the
environment variable name is not defined or the
file is not found by the search, then this
modifier expands to the empty string
The modifiers can be combined to get compound results:

%~dp1       – expands %1 to a drive letter and path only
%~nx1       – expands %1 to a file name and extension only
%~dp$PATH:1 – searches the directories listed in the PATH
environment variable for %1 and expands to the
drive letter and path of the first one found.
%~ftza1     – expands %1 to a DIR like output line
In the above examples %1 and PATH can be replaced by other
valid values.  The %~ syntax is terminated by a valid argument
number.  The %~ modifiers may not be used with %*

I bet the guy meant %~dp0 in the call to cacls
