A custom checker for Falco rules files that can be loaded using the Flycheck syntax checker for GNU Emacs.

First, install and enable Flycheck if not already installed.

The default configuration for this integration relies on running Falco via docker.

This checker is available on MELPA. Assuming you already have MELPA configured as a package source, it can be installed via:

M-x package-install RET flycheck-falco-rules RET

And then add the following to your .emacs file:

(with-eval-after-load 'flycheck
  (add-hook 'flycheck-mode-hook #'flycheck-falco-rules-setup))

1. Copy flycheck-falco-rules.el locally (for example, ~/elisp/flycheck-falco-rules.el)
2. Add the following to your .emacs file:

(load "~/elisp/flycheck-falco-rules.el")
(with-eval-after-load 'flycheck
  (add-hook 'flycheck-mode-hook #'flycheck-falco-rules-setup))

If you wish to use a local instance of falco instead, you can override the flycheck-falco-rules-validate-command variable using the standard emacs customization feature. For example M-x set-variable RET flycheck-falco-rules-validate-command RET falco -o json_output=True -V RET
