Subject: [PATCH] Remove redundant cl-lib runtime dependencies across lisp/
Date: Mon, 5 Jan 2026 03:52:48 +0900

[Message part 1 (text/plain, inline)]

Hello,

This patch series removes redundant cl-lib dependencies that are no
longer necessary following the movement of incf and decf into the Emacs
core in Emacs 31.

Patch 1 adds a new audit tool: admin/cl-lib-deps-report.el. This is a
standalone Elisp script that identifies where cl-lib is required but not
used at runtime or compile-time, helping to maintain a lean dependency
tree.

Patch 2 and Patch 3 apply the cleanup to the gnus/ directory and other
libraries under lisp/, respectively. These changes remove (require
'cl-lib) from approximately 50 files where the audit tool confirmed they
were no longer providing necessary runtime symbols.

The script also highlights cases where cl-lib is used but missing an
explicit require, though those fixes are not included in this series to
keep it focused on the cleanup.

All changes have been verified to compile without regression.

Best regards,

Kenta Usami

Thanks.

I don't think we can do this with Org files, not without talking to
Org developers first, because Org is also available for a separate
download, so it is not tightly coupled with Emacs core.  Same with
Tramp (which is available from ELPA) and possibly also use-package.
And I wouldn't waste energy and risk complications with packages in
lisp/obsolete/, since they are basically kept there for backward
compatibility.

Thank you for the comments. I have revised the patches to exclude Org,
Tramp, use-package, and obsolete libraries as suggested.

I am attaching the updated v2 patch series.

Best regards,
