Up to now, there was a central list of variable name patterns that
defined whether a variable was printed as a sorted list, as a list or as
a single value.
Now each variable group decides on its own which of the variables are
printed in which way, using the usual glob patterns. This is more
flexible since different files sometimes differ in their naming
conventions.
Two variable groups are added: license (for everything related to
LICENSE) and go (for lang/go).
In Makefiles, the variable values are aligned vertically. This format is
now also used in the show-all target, which makes it easier readable.
Some more variables have been marked as multi-value, and single-valued
variables ending in space are clearly marked. Without the latter, the
regression test would have a line with significant trailing whitespace.
The *_ENV and *_ARG values are typically very long, and reading them in
a single line is unnecessarily difficult. Therefore, each of their
values is listed on a separate line, for example:
fetch:
usr DIST_PATH (undefined)
pkg MASTER_SITES = \
http://ftp.gnome.org/pub/GNOME/sources/glib/2.56/ \
ftp://ftp.gnome.org/pub/GNOME/sources/glib/2.56/ \
ftp://ftp.cse.buffalo.edu/pub/Gnome/sources/glib/2.56/ \
https://download.gnome.org/sources/glib/2.56/ \
# end of MASTER_SITES
pkg DIST_SUBDIR (undefined)
is a new target "show-all" that fits to the existing "debug",
"show-tools", "show-vars" targets. It prints a list of the variables
that make up the public interface to pkgsrc. Running this target is
especially useful if you want to do some things, you know that they must
have been implemented but you don't know what it is called. It also
shows the "class" of a variable (user-defined, package-defined,
system-defined).
Moved the changes-entry target to misc/developer.mk. To save some time,
that file is only included when PKG_DEVELOPER is defined.
Moved the build-defs-message target to misc/show.mk and renamed it to
show-build-defs, since almost all other *-message targets just print a
single line.
