;;; Below are fragments from my Emacs configuration file
;;; (`~/.emacs.d/init.el`).
;;; <!-- more -->
;;; The newest version of this config is available from a [github
;;; repo](https://github.com/lukpank/.emacs.d).
;;; I recommend watching the following video by BuildFunThings called
;;; [My GNU Emacs configuration for programming](https://www.youtube.com/watch?v=I28jFkpN5Zk).
;;; When I want to ensure all of the packages (on a new machine) I set
;;; `use-package-always-ensure` below to `t` start Emacs and then set
;;; it back to `nil`.
;;; Basic settings
;;; ==============
;;; Directory with local Emacs lisp files
;;; -------------------------------------
;;; I add a directory to the lisp search path where I can add my own
;;; lisp code and (now less often) downloaded lisp code which is not
;;; available through [MELPA](https://melpa.org). Then I initialize
;;; secure downloading from GNU and MELPA archives of Emacs packages.
(let ((path (expand-file-name "~/.emacs.d/lisp")))

(add-to-list 'load-path path t)))
;;; Add MELPA package list
;;; ----------------------
;;; You can install many Emacs packages from [MELPA](https://melpa.org)
;;; repository. To add MELPA to the package list add the following to your
;;; `~/.emacs.d/init.el` file
(require 'package)
(setq package-archives
'(("gnu" . "https://elpa.gnu.org/packages/")
("melpa-stb" . "https://stable.melpa.org/packages/")
("melpa" . "https://melpa.org/packages/"))

tls-program '("gnutls-cli --x509cafile %t -p %p %h")
gnutls-verify-error t)
(package-initialize)
(setq use-package-always-ensure nil)
(require 'use-package)
;;; This also turns on checking TLS certificates (in both possible modes)
;;; with `tls-program` set to only the first value from the default value
;;; (for more info
;;; see
;;; [Your Text Editor Is Malware](https://glyph.twistedmatrix.com/2015/11/editor-malware.html)).
;;; Now you can list available packages by running `M-x list-packages`.
;;; Mark packages you want to install by pressing `i` and later press `x`
;;; to install all marked packages (the necessary dependencies will be
;;; installed automatically).
;;; Note: The last line above requires installing package named
;;; `use-package` to work.

;;; with
;;; ```
;;; $ go get -u golang.org/x/tools/cmd/gopls

;;; 4. Install [goimports] which can be installed from Debian package
;;; `golang-go.tools` or with
;;; ```
;;; $ go get -u golang.org/x/tools/cmd/goimports
;;; ```
;;; 5. Install [guru](https://godoc.org/golang.org/x/tools/cmd/guru)
;;; with
;;; ```
;;; $ go get -u golang.org/x/tools/cmd/guru
;;; ```
;;; 6. Add your `$GOPATH/bin` to your `PATH` environment variable (or

;;; `$GOPATH/bin` to some directory which is in your `PATH`).
