我有很多目录充满了一堆TeX文档.因此,有很多文件具有相同的基本文件名和不同的扩展名.但是,其中只有一个是可编辑的.我想要一种方法来说服Emacs,如果我在一个我所拥有的目录中
document.tex
document.log
document.pdf
document.bbl
document.aux
...

而且我在迷你游戏中并且做到了
~/Documents/.../doc<TAB>

它填写'document.tex',因为那是该目录中唯一真正可编辑的文档.有人知道这样做的好方法吗?
我写了一些应该做你想要的代码.基本思想是将变量设置'completion-ignored-extensions
为与要跳过的扩展名匹配,但仅限于存在.tex
文件时.这段代码就是这样.
(defadvice find-file-read-args (around find-file-read-args-limit-choices activate)
"set some stuff up for controlling extensions when tab completing"
(let ((completion-ignored-extensions completion-ignored-extensions)
(find-file-limit-choices t))
ad-do-it))
(defadvice minibuffer-complete (around minibuffer-complete-limit-choices nil activate)
"When in find-file, check for files of extension .tex, and if they're found, ignore .log .pdf .bbl .aux"
(let ((add-or-remove
(if (and (boundp 'find-file-limit-choices) find-file-limit-choices
(save-excursion
(let ((b (progn (beginning-of-line) (point)))
(e (progn (end-of-line) (point))))
(directory-files (file-name-directory (buffer-substring-no-properties b e)) nil "\\.tex$"))))
'add-to-list
'remove)))
(mapc (lambda (e) (setq completion-ignored-extensions
(funcall add-or-remove 'completion-ignored-extensions e)))
'(".log" ".pdf" ".bbl" ".aux")))
ad-do-it)
