emacs lisp : How to remove/delete an element of a list?

Question

我尝试了emacs lisp的第一步，从"\\.synctex\\.gz"中删除了LaTeX-clean-intermediate-suffixes元素:

(eval-after-load 'latex
  '(setq my-LaTeX-clean-intermediate-suffixes (remove '"\\.synctex\\.gz" LaTeX-clean-intermediate-suffixes)); that's not working
  '(setq LaTeX-clean-intermediate-suffixes
     (append my-LaTeX-clean-intermediate-suffixes (list "-blx\\.bib" "\\.run\\.xml"))))

如何在这里删除此元素？我找到了remove和delete，对它们都进行了尝试，但是出现了wrong-number-of-arguments-错误类型。

更新

我尝试了这个:

(eval-after-load 'latex
  (setq LaTeX-clean-intermediate-suffixes (delete "\\.synctex\\.gz"  LaTeX-clean-intermediate-suffixes))
  '(setq LaTeX-clean-intermediate-suffixes
     (append LaTeX-clean-intermediate-suffixes (list "-blx\\.bib" "\\.run\\.xml"))))

但是我在Backtrace中收到了很长的输出:-(

Answer 1

您看到的错误不是由于对列表的操作，而是由于错误使用了eval-after-load。此函数仅允许两个参数:(eval-after-load FILE FORM)。因此，您的代码段应阅读

(eval-after-load 'latex
  '(setq LaTeX-clean-intermediate-suffixes (delete "\\.synctex\\.gz"  LaTeX-clean-intermediate-suffixes)
         LaTeX-clean-intermediate-suffixes (append LaTeX-clean-intermediate-suffixes (list "-blx\\.bib" "\\.run\\.xml"))))

(因为在单个setq语句中允许多个赋值)或更一般的变体(在一个progn中包含所需的多种形式):

(eval-after-load 'latex
  '(progn
     (setq LaTeX-clean-intermediate-suffixes (delete "\\.synctex\\.gz"  LaTeX-clean-intermediate-suffixes))
     (setq LaTeX-clean-intermediate-suffixes (append LaTeX-clean-intermediate-suffixes (list "-blx\\.bib" "\\.run\\.xml")))))
