Rather than emiting warnings directly to a port, have the checkers return the
warning or warnings.
This makes it easier to use the warnings in different ways, for example,
loading the data in to a database, as you can work with the <lint-warning>
records directly, rather than having to parse the output to determine the
package and location.
* guix/scripts/lint.scm (<lint-warning>): New record type.
(lint-warning): New macro.
(lint-warning?, lint-warning-package, lint-warning-message,
lint-warning-location, package-file, make-warning): New procedures.
(call-with-accumulated-warnings, with-accumulated-warnings): Remove.
(emit-warning): Rename to emit-warnings, and switch to displaying multiple
warnings.
(check-description-style)[check-not-empty-description, check-texinfo-markup,
check-trademarks, check-quotes, check-proper-start,
check-end-of-sentence-space]: Switch to generating a list of warnings, and
using make-warning, rather than emit-warning.
(check-inputs-should-be-native, check-inputs-should-not-be-an-input-at-all):
Switch to generating a list of warnings, and using make-warning, rather than
emit-warning.
(check-synopsis): Switch to generating a list of warnings, and using
make-warning, rather than emit-warning.
[check-not-empty]: Remove, this is handled in the match clause
to avoid other warnings being emitted.
[check-final-period, check-start-article, check-synopsis-length,
check-proper-start, check-start-with-package-name, check-texinfo-markup]:
Switch to generating a list of warnings, and using make-warning, rather than
emit-warning.
[checks]: Remove check-not-empty.
(validate-uri, check-home-page, check-patch-file-names,
check-gnu-synopsis+description): Switch to generating a list of warnings, and
using make-warning, rather than emit-warning.
(check-source): Switch to generating a list of warnings, and using
make-warning, rather than emit-warning.
[try-uris]: Remove.
[warnings-for-uris]: New procedure, replacing try-uris.
(check-source-file-name, check-source-unstable-tarball, check-mirror-url,
check-github-url, check-derivation, check-vulnerabilities, check-for-updates,
report-tabulations, report-trailing-white-space, report-long-line,
report-lone-parentheses, report-formatting-issues, check-formatting): Switch
to generating a list of warnings, and using make-warning, rather than
emit-warning.
(run-checkers): Call emit-warnings on the warnings returned from the checker.
* tests/lint.scm (string-match-or-error, single-lint-warning-message): New
procedures.
(call-with-warnings, with-warnings): Remove.
