Commit a8b927a562 Added new procedure go-module-available-versions use
'string-append' to GOPROXY, but 'string->symbol' let GOPROXY is a symbol (it
must be a string), which would lead to wrong-type-arg errors in the
'string-append' procedure.
* guix/scripts/import/go.scm (%options)[goproxy]: Remove call to
'string->symbol'.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
This allows importing packages with complicated version specific dependency
chains without the package symbol names colliding.
* doc/guix.texi (Invoking guix import): Document the --pin-versions option.
Mention that a specific version can be imported. Remove the experimental
warning.
* guix/import/go.scm (go-module->guix-package-name)[version]: Add optional
argument. Rewrite the character translation in terms of string-map.
(go-module->guix-package): Conditionally use dependencies whose symbol include
their version, based no the value of the PIN-VERSIONS? argument.
* guix/import/utils.scm (package->definition): Add a new case where the full
version string is appended to the package symbol.
* guix/scripts/import.scm (guix-import): Correctly print forms starting
with '(define-public [...]'.
* guix/scripts/import/go.scm (guix-import-go): Conditionally include the
version in the package symbols defined.
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.
