copilot: Theme copilot-install-dir

[RangHo]

copilot-install-dir specifies the directory where GitHub Copilot server binary is installed for copilot-emacs/copilot.el

---

Recently (in copilot-emacs/copilot.el@26fa165bfd0e943608c628f0251e9341f0552183, specifically), the developers of GitHub Copilot integration have removed the server binary blob in an effort to get the package published on MELPA. As such, the proprietary server binary needs to be installed separately using copilot-install-server interactive command.

The original default location is user-emacs-directory/.cache/copilot.

Below is the not-so-minimal init.el file that I used to test the functionality:

(defvar elpaca-installer-version 0.7)
(defvar elpaca-directory (expand-file-name "elpaca/" user-emacs-directory))
(defvar elpaca-builds-directory (expand-file-name "builds/" elpaca-directory))
(defvar elpaca-repos-directory (expand-file-name "repos/" elpaca-directory))
(defvar elpaca-order '(elpaca :repo "https://github.com/progfolio/elpaca.git"
                              :ref nil :depth 1
                              :files (:defaults "elpaca-test.el" (:exclude "extensions"))
                              :build (:not elpaca--activate-package)))
(let* ((repo  (expand-file-name "elpaca/" elpaca-repos-directory))
       (build (expand-file-name "elpaca/" elpaca-builds-directory))
       (order (cdr elpaca-order))
       (default-directory repo))
  (add-to-list 'load-path (if (file-exists-p build) build repo))
  (unless (file-exists-p repo)
    (make-directory repo t)
    (when (< emacs-major-version 28) (require 'subr-x))
    (condition-case-unless-debug err
        (if-let ((buffer (pop-to-buffer-same-window "*elpaca-bootstrap*"))
                 ((zerop (apply #'call-process `("git" nil ,buffer t "clone"
                                                 ,@(when-let ((depth (plist-get order :depth)))
                                                     (list (format "--depth=%d" depth) "--no-single-branch"))
                                                 ,(plist-get order :repo) ,repo))))
                 ((zerop (call-process "git" nil buffer t "checkout"
                                       (or (plist-get order :ref) "--"))))
                 (emacs (concat invocation-directory invocation-name))
                 ((zerop (call-process emacs nil buffer nil "-Q" "-L" "." "--batch"
                                       "--eval" "(byte-recompile-directory \".\" 0 'force)")))
                 ((require 'elpaca))
                 ((elpaca-generate-autoloads "elpaca" repo)))
            (progn (message "%s" (buffer-string)) (kill-buffer buffer))
          (error "%s" (with-current-buffer buffer (buffer-string))))
      ((error) (warn "%s" err) (delete-directory repo 'recursive))))
  (unless (require 'elpaca-autoloads nil t)
    (require 'elpaca)
    (elpaca-generate-autoloads "elpaca" repo)
    (load "./elpaca-autoloads")))
(add-hook 'after-init-hook #'elpaca-process-queues)
(elpaca `(,@elpaca-order))

;; Install use-package support
(elpaca elpaca-use-package
  ;; Enable use-package :ensure support for Elpaca.
  (elpaca-use-package-mode))

;; Block until current queue processed.
(elpaca-wait)

(use-package no-littering
  :ensure (:repo "/path/to/no-littering/"))

(elpaca-wait)

(use-package copilot
  :ensure (:host github :repo "copilot-emacs/copilot.el))
