Huge thanks to Sam James and Arthur Zamarin for support and interest in getting this feature done.

Installation

Unmasking

The Flycheck integration is unreleased as of now, this will (hopefully) change in the future, but for now You need live versions of snakeoil, pkgcore and pkgcheck.

File: /etc/portage/package.accept_keywords/pkgcore.conf

1
2
3

dev-python/snakeoil  **
sys-apps/pkgcore     **
dev-util/pkgcheck    **

Also You will need to unmask app-emacs/flycheck and its dependencies.

File: /etc/portage/package.accept_keywords/emacs.conf

1
2
3

app-emacs/epl
app-emacs/pkg-info
app-emacs/flycheck

Emerging

Install pkgcheck with the emacs USE flag enabled.

File: /etc/portage/package.use/pkgcore.conf

1

dev-util/pkgcheck    emacs

Afterwards run:

1
2

emerge -1av dev-python/snakeoil sys-apps/pkgcore dev-util/pkgcheck
emerge -av --noreplace dev-util/pkgcheck

Configuration

Following is what I would suggest to put into your Emacs config file:

1
2
3
4
5
6
7
8

(require 'ebuild-mode)
(require 'flycheck)
(require 'flycheck-pkgcheck)

(setq flycheck-pkgcheck-enable t)

(add-hook 'ebuild-mode-hook 'flycheck-mode)
(add-hook 'ebuild-mode-hook 'flycheck-pkgcheck-setup)

If You are using use-package:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

(use-package flycheck
  :ensure nil)

(use-package ebuild-mode
  :ensure nil
  :hook ((ebuild-mode . flycheck-mode)))

(use-package flycheck-pkgcheck
  :ensure nil
  :custom ((flycheck-pkgcheck-enable t))
  :hook ((ebuild-mode . flycheck-pkgcheck-setup)))

The lines with :ensure nil are there to prevent use-package from trying to download the particular package from Elpa (because we use system packages for this configuration).
