This library provides a flycheck checker for the metadata in Emacs Lisp files which are intended to be packages.

Currently these checks are only activated if a Package-Requires or Package-Version header is present in the file, and checks center on the validity of the data in that header.


You'll need Emacs 24 for flycheck, so the recommended way to get flycheck-package is as a package from the MELPA repository. The version of flycheck-package there will always be up-to-date. There are also packages in MELPA Stable, which track the latest numbered tag.

If you insist on doing things the hard way, first ensure flycheck is installed, then download this code and add the directory to your Emacs load-path.

Then, in your init.el:

(eval-after-load 'flycheck


Once this is more useful, the plan is to extract the checks into a separate package-lint.el, which can then be used by this checker and also by MELPA – this will probably be essential in order to check multi-file packages helpfully anyway.

Additional checks for a future package-lint.el, some of which are currently performed by other flycheck checkers:
