Clojure是否有彩色REPL? [英] Is there a colored REPL for Clojure?
问题描述
我想为clojure代码得到一个有颜色的REPL,类似于你可以用IRB for Ruby做的。
有用户的库或设置
我不知道方法有基本的Clojure REPL,由 java -cp clojure.jar clojure.main
开始,执行语法高亮。但是,如果你使用Emacs& SLIME(Clojure社区很大一部分选择的开发环境!),那么你可以使用SLIME REPL高亮语法,如 clojure-mode
。
clojure-mode
函数中取出一些代码(定义在<$ c $的顶部) c> clojure-mode.el ): ;;;这个函数中的所有代码都从clojure-mode函数中提取
;;;从clojure-mode.el
(defun clojure-font-lock-setup()
(交互式)
(make-local-variable'lisp-indent-function)
'clojure-indent-function)
(set(make-local-variable'lisp-doc-string-elt-property)
'clojure-doc-string-elt)
(make-local-variable'font-lock-multiline)t)
(add-to-list'font-lock-extend-region-functions
'clojure-font-lock- extend-region-def t)
(当clojure-mode-font-lock-comment-sexp
(add-to-list'font-lock-extend-region-functions
'clojure-font-lock-extend-region-comment t)
(make-local-variable'clojure-font-lock-keywords)
(add-to-list'clojure- lock-keywords
'clojure-font-lock-mark-comment t)
(set(make-local-variable'open-paren-in-column-0-is-defun-start)nil) )
(setq font-lock-defaults
'(clojure-font-lock-keywords; keywords
nil nil
((+ - * /。 ;> =!?$%_&〜^:@。 w));语法alist
nil
(font-lock-mark-block-function。mark-defun)
(font-lock-syntax-face-function
。lisp-font-lock -syntactic-face-function))))
然后将它添加到 slime-repl-mode-hook
:
(add-hook'slime-repl-mode- hook
(lambda()
(font-lock-mode nil)
(clojure-font-lock-setup)
$ b
Etvoilà,下次连接SLIME REPL时,您将拥有 clojure-模式
语法高亮显示。如果你对Common Lisp也使用SLIME,你需要调整它,所以它不会试图用CL做Clojure高亮显示。此外,这只是第一个近似;一个事情,它的类型的突破是提示突出显示(命名空间>
的东西将不再突出显示)。我不是一个熟练的 font-lock
黑客通过任何想象力,所以我会离开它。 : - )
I'd like to get a colored REPL for clojure code, similar to what you can do with IRB for Ruby.
Are there any libraries or settings for user.clj that provide automatic coloring of the REPL?
Example IRB:
I do not know of any way to have the basic Clojure REPL, as started by something like java -cp clojure.jar clojure.main
, do syntax highlighting. If, however, you use Emacs & SLIME (the development environment of choice of a great part of the Clojure community!), then you can have the SLIME REPL highlight syntax like clojure-mode
does.
First, you'll have to lift some code from the clojure-mode
function (defined towards the top of clojure-mode.el
):
;;; all code in this function lifted from the clojure-mode function
;;; from clojure-mode.el
(defun clojure-font-lock-setup ()
(interactive)
(set (make-local-variable 'lisp-indent-function)
'clojure-indent-function)
(set (make-local-variable 'lisp-doc-string-elt-property)
'clojure-doc-string-elt)
(set (make-local-variable 'font-lock-multiline) t)
(add-to-list 'font-lock-extend-region-functions
'clojure-font-lock-extend-region-def t)
(when clojure-mode-font-lock-comment-sexp
(add-to-list 'font-lock-extend-region-functions
'clojure-font-lock-extend-region-comment t)
(make-local-variable 'clojure-font-lock-keywords)
(add-to-list 'clojure-font-lock-keywords
'clojure-font-lock-mark-comment t)
(set (make-local-variable 'open-paren-in-column-0-is-defun-start) nil))
(setq font-lock-defaults
'(clojure-font-lock-keywords ; keywords
nil nil
(("+-*/.<>=!?$%_&~^:@" . "w")) ; syntax alist
nil
(font-lock-mark-block-function . mark-defun)
(font-lock-syntactic-face-function
. lisp-font-lock-syntactic-face-function))))
Then add it to the slime-repl-mode-hook
:
(add-hook 'slime-repl-mode-hook
(lambda ()
(font-lock-mode nil)
(clojure-font-lock-setup)
(font-lock-mode t)))
Et voilà, next time you connect to the SLIME REPL you'll have clojure-mode
syntax highlighting available. If you use SLIME for Common Lisp too, you'll want to tweak this so it doesn't try to do Clojure highlighting with CL. Also, this is just a first approximation; one thing it sort of breaks is prompt highlighting (the namespace>
thing will not be highlighted anymore). I'm not a proficient font-lock
hacker by any stretch of the imagination, though, so I'll leave it at that. :-)
