2021-12-23Remove VM generation dead-code....This code duplicates the (gnu system image) and (gnu build image) code. Using VM for image generation is not needed, not portable and really slow. Remove all the VM image generation code to make sure that only the image API is used. * gnu/build/vm.scm: Remove it. Move the qemu-command procedure to ... * gnu/build/marionette.scm: ... here. * gnu/local.mk (GNU_SYSTEM_MODULES): Adapt it. * tests/modules.scm: Ditto. * gnu/tests/install.scm: Ditto. * gnu/system/vm.scm: Adapt it and remove expression->derivation-in-linux-vm, qemu-img, system-qemu-image/shared-store and system-docker-image procedures. * doc/guix.texi (G-Expressions): Adapt it. Mathieu Othacehe
2017-05-25modules: Raise an error when a dependency could not be found....* guix/modules.scm (&missing-dependency-error): New error condition. (source-module-dependencies): Raise it when 'search-path' returns #f. * tests/modules.scm ("&missing-dependency-error"): New test. Ludovic Courtès
2016-09-05Add (guix modules)....* guix/modules.scm, tests/modules.scm: New files. * Makefile.am (MODULES, SCM_TESTS): Add them. * doc/guix.texi (G-Expressions): Add an example of 'source-module-closure'. Ludovic Courtès

(special-form-lead, newline-form?, escaped-string) (string-width, canonicalize-comment, pretty-print-with-comments) (object->string*): Move to... * guix/read-print.scm: ... here. New file. * guix/scripts/import.scm: Adjust accordingly. * tests/style.scm: Move 'test-pretty-print' and tests to... * tests/read-print.scm: ... here. New file. * Makefile.am (MODULES): Add 'guix/read-print.scm'. (SCM_TESTS): Add 'tests/read-print.scm'. Ludovic Courtès 2022-07-04style: For 'let' and similar forms, emit one binding per line....Previously, 'let' bindings could be rendered like this: (let ((x 1) (y 2) (z 3)) ...) With this change, each bindings goes in its own line. Partly fixes <https://issues.guix.gnu.org/56297>. Reported by Maxime Devos <maximedevos@telenet.be>. * guix/scripts/style.scm (pretty-print-with-comments)[list-of-lists?]: New procedure. Use it. * tests/style.scm: Add tests with 'let' and 'substitute-keyword-arguments'. Ludovic Courtès 2022-06-22style: Keep values next to their keyword....This ensures we print '#:key value' rather than insert a newline between '#:key' and 'value' as was the case before. * guix/scripts/style.scm (pretty-print-with-comments)[print-sequence]: When ITEM is a keyword, loop with FIRST? = true. * tests/style.scm: Add test. Ludovic Courtès 2022-04-14style: Correctly read dots in pairs and improper lists....Until now dots were read as symbols. * guix/scripts/style.scm (read-with-comments)[dot]: New variable. [dot?, reverse/dot]: New procedures. Use 'reverse/dot' instead of 'reverse' when reading lists. * tests/style.scm ("read-with-comments: dot notation") ("((a . 1) (b . 2))", "(a b c . boom)"): New tests. Ludovic Courtès 2022-01-10style: '-S format' canonicalizes comments....* guix/scripts/style.scm (canonicalize-comment): New procedure. (pretty-print-with-comments): Add #:format-comment. and honor it. (object->string*): Add 'args' and honor them. (format-package-definition): Pass #:format-comment to 'object->string*'. * tests/style.scm ("pretty-print-with-comments, canonicalize-comment"): New test. Ludovic Courtès 2022-01-10style: Add '--styling' option....* guix/scripts/style.scm (format-package-definition): New procedure. (%options, show-help): Add "--styling". (%default-options): Add 'styling-procedure'. (guix-style): Honor it. * tests/style.scm (with-test-package) ("input labels, 'safe' policy") ("input labels, 'safe' policy, nothing changed") ("input labels, margin comment") ("input labels, margin comment on long list") ("input labels, line comment") ("input labels, modify-inputs and margin comment"): Pass "-S inputs". * etc/indent-code.el: Remove. * doc/contributing.texi (Formatting Code): Mention "guix style" instead of "etc/indent-code.el". (Submitting Patches): Add item for "guix style". * doc/guix.texi (Invoking guix style): Document "-S" and update. Ludovic Courtès 2022-01-10style: Add support for "newline forms"....This allows us to express cases where a newline should be inserted immediately after the head symbol of a list. * guix/scripts/style.scm (%newline-forms): New variable. (newline-form?): New procedure. (pretty-print-with-comments): Handle "newline forms". * tests/style.scm: Add test. Ludovic Courtès 2022-01-10style: Allow special forms to be scoped....* guix/scripts/style.scm (vhashq): Add clause for 'lst, and change default clause. (%special-forms): Add context for 'add-after and 'add-before. Add 'replace. (prefix?, special-form-lead): New procedures. (special-form?): Remove. (pretty-print-with-comments): Add 'context' to the threaded state. Adjust 'print-sequence' and adjust 'loop' calls accordingly. * tests/style.scm: Add tests for 'replace.
