* guix/build/gnu-build-system.scm (%parallel-job-count): New variable.
(build, check): Use it instead of $NIX_BUILD_CORES.
* guix-build.in (guix-build): Default to 0 for the #:build-cores option.
* guix/build/utils.scm (substitute): Do not pass the OUT to PROC; use
`list-matches' instead of `regexp-exec' and pass a list of matches to
PROC. Expect PROC to return a string, and output that. Fold over
RX+PROC in order. Use `(read-line p 'concat)' to include the trailing
delimiter in LINE.
(substitute*): Produce code to iterate over the matches, and return a
string, which includes anything from the original line that's in
between matches.
* distro/base.scm (gcc-4.7, glibc): Adjust accordingly: remove use
of (ice-9 regex) and `regexp-substitute/global'; return a string.
* guix/build/gnu-build-system.scm (set-paths): Add new `path-exclusions'
parameter; honor it.
* guix/build-system/gnu.scm (gnu-build): New `path-exclusions' keyword
parameter; pass it to BUILDER.
* distro/base.scm (gcc-4.7): Exclude "libc" from $LIBRARY_PATH.
* guix/build/gnu-build-system.scm (strip): New procedure.
(%standard-phases): Add it.
* guix/build-system/gnu.scm (gnu-build): New `strip-binaries?',
`strip-flags', and `strip-directories' keyword parameters. Pass them
to BUILDER.
* guix/build/utils.scm (patch-shebang): Add an optional `path'
parameter. Change SHEBANG-RX to match the whole interpreter file
name. Don't patch when BIN and CMD are the same. Add docstring.
* guix/build/gnu-build-system.scm (patch-shebangs): New procedure.
(%standard-phases): Add it.
* guix/build-system/gnu.scm (gnu-build): New `patch-shebangs?' keyword
parameter. Pass it to the builder's `gnu-build'.
* guix/build/utils.scm (substitute): Change to accept a `pattern+procs'
parameter. Iterate over it.
(substitute*): Adjust accordingly.
* distro/base.scm (guile-1.8): Adjust accordingly.
* guix/build/utils.scm (let-matches, substitute*): New macros.
* distro/base.scm (guile-1.8): Use `substitute*' instead of
`substitute'. Remove the #:modules argument.
* guix/build/gnu-build-system.scm (set-paths): Dump the value of
environment variables in the `environment-variables' files, similar to
what Nixpkgs does.
* guix/build/gnu-build-system.scm (patch): New procedure.
(%standard-phases): Add `patch'.
* guix/build-system/gnu.scm (gnu-build): Add `patches' and `patch-flags'
parameters. Pass them on.
* guix/build/gnu-build-system.scm (set-paths, build, check, install):
New procedures.
(unpack): Make `source' a keyword arg; add `#:allow-other-keys'.
(configure): Likewise.
(%standard-phases): New variable.
(gnu-build): Make `source', `outputs', and `inputs' keyword arguments;
add `phases' keyword argument; #:allow-other-keys; add rest arguments
`args'. Invoke each of PHASES in order within `every'.
* guix/gnu-build-system.scm (gnu-build): Add `make-flags' and `phases'
keyword arguments. Update builder's `gnu-build' call to match the new
convention.
* guix/derivations.scm (build-expression->derivation): Add all of INPUTS
as inputs to the final derivation.
* guix/build/gnu-build-system.scm, guix/build/utils.scm,
guix/gnu-build-system.scm: New files.
* tests/builders.scm ("gnu-build"): New test.
* guix/derivations.scm (imported-modules): New procedure.
(build-expression->derivation): New keyword argument `modules'.
Use `imported-modules' when MODULES is non-empty, and pass it with
`-L' to GUILE.
* guix/build/http.scm, guix/http.scm, tests/builders.scm: New files.
