Fixes <https://bugs.gnu.org/32966>.
Reported by Clément Lassieur <clement@lassieur.org>.
* guix/gexp.scm (gexp-attribute): Add 'equal?' optional parameter; pass
it to 'delete-duplicates'.

it.

* tests/gexp.scm ("imported-files with file-like objects"): Add 'file=?'
and use it instead of calling 'readlink'.
* guix/gexp.scm (gexp->derivation): Add #:import-creates-derivation?.
Pass #:derivation? to 'imported-modules' and 'compiled-modules'. In -L
argument, check whether MODULES is a derivation.

(file-mapping->tree): New procedure.
(imported-files): Rename to...
(imported-files/derivation): ... this.

pass it to 'imported-files'.
* guix/packages.scm (patch-and-repack): Pass
#:import-creates-derivation? to 'gexp->derivation'.
* tests/gexp.scm ("imported-files"): Adjust to no longer expect a
derivation.
Until now 'compiled-modules' would override (guix build utils) with its
own. Thus, when asked to build a different (guix build utils),
via #:module-path, it would fail badly because a (guix build utils)
module was already loaded and possibly incompatible with the new one.
This happened when running 'guix pull --branch=core-updates' from
current master: in 'core-updates', (guix build utils) exports
'ignore-error?' but in 'master' it does not. Thus, 'guix pull' would
fail with:
no binding `invoke-error?' in module (guix build utils)
builder for `/gnu/store/…-module-import-compiled.drv' failed with exit code 1
cannot build derivation `/gnu/store/…-compute-guix-derivation.drv': 1 dependencies couldn't be built
This patch fixes it.
* guix/gexp.scm (compiled-modules)[build-utils-hack?]: New variable.
[build]: Load MODULES/build/utils.scm when it exists.
Fixes <https://bugs.gnu.org/31450>.
Reported by Martin Castillo <castilma@uni-bremen.de>.
* guix/gexp.scm (gexp->derivation): Pass #:deprecation-warnings to
'imported-modules'.
(imported-files): Add #:deprecation-warnings and pass #:env-vars to
'gexp->derivation'.
(imported-modules): Add #:deprecation-warnings and pass it to
'imported-files'.
* guix/gexp.scm (<scheme-file>)[splice?]: New field.
(scheme-file): Add #:splice? and pass it to '%scheme-file'.
(scheme-file-compiler): Pass SPLICE? to 'gexp->file'.
(gexp->file): Add #:splice? and honor it.
* tests/gexp.scm ("gexp->file + #:splice?"): New test.
("gexp->derivation & with-imported-module & computed module"): Use
#:splice? #t.
* guix/gexp.scm (compiled-modules)[build]: Add 'processed' parameter to
'process-entry' and 'process-directory'. Print a message before each
'compile-file' call.
* doc/guix.texi (Messaging Services): Update accordingly.
* gnu/services/configuration.scm (serialize-configuration,
serialize-maybe-stem, serialize-package): Return strings or string-valued
gexps (these procedures were only used for their side-effects).
* gnu/services/messaging.scm (serialize-field, serialize-field-list,
enclose-quotes, serialize-raw-content, serialize-ssl-configuration,
serialize-virtualhost-configuration-list,
serialize-int-component-configuration-list,
serialize-ext-component-configuration-list,
serialize-virtualhost-configuration, serialize-int-component-configuration,
serialize-ext-component-configuration, serialize-prosody-configuration):
Return strings or string-valued gexps and stop printing.
(prosody-activation): Use SERIALIZE-PROSODY-CONFIGURATION's return value with
MIXED-TEXT-FILE instead of using its output with PLAIN-FILE.
(serialize-non-negative-integer, serialize-non-negative-integer-list): Convert
numbers to strings.
(file-object?, serialize-file-object, file-object-list?,
serialize-file-object-list): New procedures.
(ssl-configuration)[capath, cafile], (prosody-configuration)[plugin-paths,
groups-file]: Replace FILE-NAME with FILE-OBJECT.
* guix/gexp.scm (file-like?): New exported procedure.
Previously things returned by 'program-file', such as %MODPROBE-WRAPPER
in (gnu services), would refer to 'guile-final'. This would introduce
'guile-final' in the system closure, which is otherwise absent. By
referring to 'guile-2.2' we remove that extra Guile.
* guix/gexp.scm (default-guile): Refer to GUILE-2.2 instead of
GUILE-FINAL.
This avoids repeated deprecation messages, particularly while running
'guix system build' or similar.
* guix/gexp.scm (gexp->derivation): Add #:deprecation-warnings. Pass it
to 'compiled-modules'.
(compiled-modules): Add #:deprecation-warnings and honor it.
* doc/guix.texi (G-Expressions): Update 'gexp->derivation'
documentation.
* guix/packages.scm (patch-and-repack): Pass #:deprecation-warnings #t.
Reported by Ricardo Wurmus.
* guix/gexp.scm (local-file): Define using 'syntax-case' instead of
'syntax-rules'. Explicitly handle the zero-argument case and the
use-as-an-identifier case.
Previously, (gexp-native-inputs #~#$@(list #~#+foo)) would return '().
This is a followup to 5b14a7902c.
* guix/gexp.scm (gexp-inputs)[add-reference-inputs]: In the list case,
remove 'if' around 'fold-right'. In 'map' lambda, always inherit N?.
* tests/gexp.scm ("gexp list splicing + ungexp-splicing"): New test.
* guix/gexp.scm (imported-files)[file-pair]: Add case for pairs where
the cdr is not a string.
(imported-modules): Support '=>' syntax in MODULES.
* tests/gexp.scm ("imported-files with file-like objects")
("gexp->derivation & with-imported-module & computed module"): New tests.
* doc/guix.texi (G-Expressions): Document '=>' syntax for
'with-imported-modules'.
* guix/gexp.scm (gexp)[substitute-ungexp]: Wrap body in 'with-syntax'
and pass EXP as the last argument to 'syntax-error'.
[substitute-ungexp-splicing]: Pass EXP as the last argument to
'syntax-error'.
Previously, 'gexp-native-inputs' would not return the native inputs of
nested gexps. For example, this:
(gexp-native-inputs #~(foo #$#~(bar #+coreutils)))
would return '().
* guix/gexp.scm (gexp-inputs)[add-reference-inputs]: In the
non-recursive cases, check whether N? and NATIVE? are the same, and act
accordingly.
[native-input?]: Remove.
Fold over all of (gexp-references exp).
* tests/gexp.scm ("ungexp + ungexp-native, nested, special mixture"):
New test.
* tests/gexp.scm ("input list splicing + ungexp-native-splicing"): Pass
#:native? #t to 'gexp-input'.
* guix/gexp.scm (<file-append>): New record type.
(file-append): New procedure.
(file-append-compiler): New gexp compiler.
* tests/gexp.scm ("file-append", "file-append, output")
("file-append, nested", "gexp->file + file-append"): New tests.
* doc/guix.texi (G-Expressions): Use it in 'nscd' and 'list-files'
examples. Document 'file-append'.
* guix/gexp.scm (<gexp-compiler>)[expand]: New field.
(default-expander, lookup-expander): New procedures.
(define-gexp-compiler): Add second pattern to allow for the definition
of both a compiler and an expander.
(gexp->sexp)[reference->sexp]: Call 'lookup-expander' and use its
result.
* guix/gexp.scm (<gexp>)[modules]: New field.
(gexp-modules): New procedure.
(gexp->derivation): Use it and append the result to %MODULES.
Update docstring to mark #:modules as deprecated.
(current-imported-modules, with-imported-modules): New macros.
(gexp): Pass CURRENT-IMPORTED-MODULES as second argument to 'gexp'.
(gexp->script): Use and honor 'gexp-modules'; define '%modules'.
* tests/gexp.scm ("gexp->derivation & with-imported-modules")
("gexp->derivation & nested with-imported-modules")
("gexp-modules & ungexp", "gexp-modules & ungexp-splicing"):
New tests.
("program-file"): Use 'with-imported-modules'. Remove #:modules
argument to 'program-file'.
* doc/guix.texi (G-Expressions): Document 'with-imported-modules'.
Mark #:modules of 'gexp->derivation' as deprecated.
* emacs/guix-devel.el: Add syntax for 'with-imported-modules'.
(guix-devel-keywords): Add it.
* .dir-locals.el: Likewise.
