我无法使用intero获得在emacs中出现的hlint建议.
~/.emacs文件中我读过解决方案是:
(flycheck-add-next-checker 'intero
'(warning . haskell-hlint))
但我不知道我应该怎么做.如果我将其添加到我的~/.emacs文件中,则emacs会在启动时失败.
(其余的似乎没问题 - 当我打开一个Haskell文件时,intero会启动 - 错误会在我输入时立即被标记.)
如何获得Hlint建议？
我正在尝试让 intero运行。安装后，从现有堆栈项目中打开 Haskell 文件会导致：
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
signal(wrong-type-argument (stringp nil))
flycheck-buffer()
flycheck-buffer-automatically()
flycheck-perform-deferred-syntax-check()
set-window-buffer(#<window 1 on Lib.hs> #<buffer Lib.hs>)
window--display-buffer(#<buffer Lib.hs> #<window 1 on Lib.hs> reuse ((inhibit-same-window)))
display-buffer-same-window(#<buffer Lib.hs> ((inhibit-same-window)))
display-buffer(#<buffer Lib.hs> (display-buffer-same-window (inhibit-same-window)))
pop-to-buffer(#<buffer Lib.hs> (display-buffer-same-window (inhibit-same-window)) nil)
pop-to-buffer-same-window(#<buffer Lib.hs>)
find-file("~/test/src/Lib.hs" t)
funcall-interactively(find-file "~/test/src/Lib.hs" t)
call-interactively(find-file nil nil)
command-execute(find-file)
当我flycheck-buffer在同一个缓冲区中运行时，即使源代码中有错误，也没有任何反应。
这是我的.emacs文件的内容：
(setq debug-on-error t)
(require 'package)
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/") t)
(package-initialize)
(package-refresh-contents)
(package-install 'intero)
(add-hook 'haskell-mode-hook 'intero-mode)
由于我在 Mac …
