Melpa Status Melpa Stable Status GNU Guix Status


This library provides a flycheck checker for the GNU Guile programming language. It requires a working Geiser configuration, and runs guild compile on your code to collect warnings and errors.



This package is available on MELPA.

After following MELPA's Getting Started guide, you can install this package with M-x package-install flycheck-guile.


This package is available on Guix.

It can be installed to your user profile with guix install emacs-flycheck-guile.

Manual installation

To install it manually, just download this code add the directory to your Emacs load-path.


Call (require 'flycheck-guile) somewhere in your Emacs configuration to load the checker.

Once loaded, the checker will automatically activate in scheme-mode buffers with geiser-mode active, where guile is the current scheme implementation.


This package can be configured via M-x customize-group flycheck-guile.

The flycheck-guile-warnings variable contains the list of warnings reported by the compiler. If you find a warning particularly annoying (eg. spurious "unused variable" warnings), it can be suppressed by removing it from this list.

The flycheck-guile-args variable contains a list of additional arguments to be passed to guild compile. This can be useful to pass an --r6rs or --r7rs argument when working with standard Scheme.


If it seems like the checker is not working, try running M-x flycheck-verify-checker guile for some diagnostics.

It may also be useful to run M-x flycheck-compile guile, which shows the full compilation command and its output.

If the checker is working, but can't find your guile modules (ie. reporting "no code for module" errors), make sure that you have correctly configured your Geiser REPL. The geiser-guile-load-path and geiser-repl-add-project-paths variables control how Geiser sets up paths, and the checker also uses these to determine the load path arguments for guild compile.

If your project has scheme files in the top-level, so the Guile module (foo bar baz) is declared in foo/bar/baz.scm, set geiser-repl-add-project-paths to t or '(".").

If your project has scheme files in a sub-directory "src", so the Guile module (foo bar baz) is declared in src/foo/bar/baz.scm, set geiser-repl-add-project-paths to '("src").
