Re: req-package

[Edward Knyshov]

Yes, sure. Sorry for late answer. Here is example. I configure clojure
development environment with req-package(use-package)

(req-package eldoc
​​ ;; this form call will download eldoc package from elpa or el-get as
needed

  :commands eldoc
​​
​​
-mode
​​ ;; this parameter delays loading of eldoc until eldo-mode function is
called

  :init (prog
​​
n (add-h
​​
ook 'emacs-lisp-mode-hook (lambda () (eldoc-mode 1)))
​ ​;; add eldoc to emacs lisp mode

​                      ​
  (add-hook 'lisp-interaction-mode-hook (lambda () (eldoc-mode 1)))))
​​
;; add eldoc to
​lisp based interaction modes
 modes
​​
​​
​​
​​
​​
​​
​​
​​
​​
​​
​​
​​
​​
​​
​​
​​

​​
​​
(req-package clojure-mode
​​
 ;; this form call will download
​clojure-mode
 package from elpa or el-get as needed
  :mode (("clj\\'" . clojure-mo
​​
de)
​ ;; this parameter delays loading of clojure-mode until ​

​                 ​
("cljs\\'" . clojure-mode)))
​ ;; file with any of these extensions is loaded​


(req-package cider
​​
 ;; this form call will download
​cider
 package from elpa or el-get as needed
  :require (clojure-m
​​
ode eldoc)
​ ;; this parameters makes sure that this req-package form is evaluated
after all of these packages are loaded​

  :commands cider-mode
​ ;; delay loading until cider-mode function is called​

  :init (progn (add-hook 'clojure-mode-h
​​
ook #'cider-mode)
​ ;; start cider in clojure mode​


​                      ​
(add-hook 'cider-mode-hook #'eldoc-mode)
​ ;; start eldoc after cider setups some of its internal things and calls
its hook​


​                      ​
(setq nrepl-log-messages t)))
​ ;; some logging stuff


(req-package-finish)​ ;; start loading

This
​ example may bit a bit hard to understand in concrete, but you may get an
idea.​
