From a8b927a562aad7e5f77d0e4db2d9cee3434446d2 Mon Sep 17 00:00:00 2001 From: Maxim Cournoyer Date: Fri, 19 Mar 2021 16:41:51 -0400 Subject: import: go: Add an option to use pinned versions. The ability to pin versions is handy when having to deal to packages that bootstrap themselves through a chain of former versions. Not using pinned versions in these case could introduce dependency cycles. * guix/build-system/go.scm (guix) (%go-version-rx): Rename to... (%go-pseudo-version-rx): ... this. Simplify the regular expression, which in turns makes it more robust. * guix/build-system/go.scm (go-version->git-ref): Adjust following the above rename. (go-pseudo-version?): New predicate. (go-module-latest-version): Rename to ... (go-module-version-string): ... this. Rename goproxy-url argument to just goproxy. Add a VERSION keyword argument, update docstring and adjust to have it used. (go-module-available-versions): New procedure. (%go.mod-require-directive-rx): Document regexp. (parse-go.mod): Harmonize the way dependencies are recorded to a list of lists rather than a list of pairs, as done for other importers. Rewrite to directly pass multiple values rather than a record object. Filter the replaced modules in a functional style. (go-module->guix-package): Add docstring. [version, pin-versions?]: New arguments. Rename the GOPROXY-URL argument to GOPROXY. Adjust to the new returned value of fetch-go.mod, which is a string. Fail when the provided version doesn't exist. Return a list dependencies and their versions when in pinned versions mode, else just the dependencies. (go-module-recursive-import)[version, pin-versions?]: New arguments. Honor the new arguments and guard against network errors. * guix/scripts/import/go.scm (%default-options): Register a default value for the goproxy argument. (show-help): Document that a version can be specified. Remove the --version argument and add a --pin-versions argument. (%options)[version]: Remove option. [pin-versions]: Add option. (guix-import-go): Adjust so the version provided from the module name is honored, along the new pin-versions? argument. * tests/go.scm: Adjust and add new tests. --- guix/scripts/import/go.scm | 70 +++++++++++++++++++++++++--------------------- 1 file changed, 38 insertions(+), 32 deletions(-) (limited to 'guix/scripts/import') diff --git a/guix/scripts/import/go.scm b/guix/scripts/import/go.scm index afdba4e8f1..33d2470ce1 100644 --- a/guix/scripts/import/go.scm +++ b/guix/scripts/import/go.scm @@ -1,5 +1,6 @@ ;;; GNU Guix --- Functional package management for GNU -;;; Copyright © 2020 Katherine Cox-Buday +;;; Copyright © 2020 Katherine Cox-Buday +;;; Copyright © 2021 Maxim Cournoyer ;;; ;;; This file is part of GNU Guix. ;;; @@ -27,28 +28,30 @@ #:use-module (srfi srfi-37) #:use-module (ice-9 match) #:use-module (ice-9 format) + #:use-module (ice-9 receive) #:export (guix-import-go)) - + ;;; ;;; Command-line options. ;;; (define %default-options - '()) + '((goproxy .
