# Usage: ./pre-inst-env COMMAND ARG...
#
# Run COMMAND in a pre-installation environment.  Typical use is
# "./pre-inst-env guix build hello".

# By default we may end up with absolute directory names that contain '..',
# which get into $GUILE_LOAD_PATH, leading to '..' in the module file names
# recorded by Guile.  To avoid that, make sure we get a real absolute
# directory name.  Additionally, use '-P' to get the canonical directory name
# so that Guile's 'relative' %file-port-name-canonicalization can actually
# work (see <http://bugs.gnu.org/17935>.)

<div class='commit-subject'>gexp: computed-file: Prevent mistakenly overriding default option values.</div><div class='commit-msg'>In order to do so, default to an empty options list, and expose options whose
default values are sensitive directly as keyword arguments.

* guix/gexp.scm (computed-file): Extract the LOCAL-BUILD? parameter from the
OPTIONS parameter to make it a stand-alone keyword argument.  Introduce an
OPTIONS* binding which is obtained by combining the LOCAL-BUILD? keyword and
its value with OPTIONS.
* doc/guix.texi (G-Expressions): Adjust doc.
