Package: debhelper
Version: 8.9.12
Severity: wishlist
With the recent introduction of executable config files, there's a fear
that we could end up with a lot of very different implementations that
essentially accomplish the same thing.
To get ahead of that, I'm proposing a different option: a script (or a
set of scripts) that expand various kinds of variables within an
executable file.
One would use this script as the interpreter for the script, the running
script would slurp in its own source, do the substitutions, and echo the
results back.
This way, the easy things would remain easy, just a
"#!/usr/lib/debhelper/dh_subst" away, and harder things would still be
possible. Everybody wins!
I was thinking of multiple scripts, all residing under
/usr/lib/debhelper/dh_subst_*, and a wrapper script, dh_subst, that
would run all of the dh_subst_* scripts. We could have
dh_subst_multiarch, dh_subst_env and similar scripts, all doing one
thing only.
The end result would become something like the following .install file:
,----
| #!/usr/lib/debhelper/dh_subst
| debian/tmp/usr/lib/${DEB_HOST_MULTIARCH}/libfoo.so.*
| debian/${VARIANT}/foo.conf /etc/foo/
`----
I have a half-baked implementation too, but documentation and tests are
missing, and as such, I'm not comfortable showing it just yet. I'd like
to hear your opinion about this suggestion before I go further.
