通常，编译错误会以file:line语法显示。
将它直接复制粘贴以打开右侧的文件会很不错。
Emacs已经有一些模式可以在缓冲区（compile-mode，iirc）中处理这个问题，但是我想从shell命令行中获取它，因为我在emacs之外的大部分时间都使用标准shell。 / p>
知道如何调整emacs以了解file:line语法，以便在file行打开line吗？ （显然，如果file:line确实存在于磁盘上，则应该优先打开它）

您可以使用emacsclient执行此操作。例如在第4行第3列打开FILE：
emacsclient +4:3 FILE
取消:3只需在第4行打开文件。

我的.emacs中有以下内容，但我发现它并没有像我想象的那样有用。

这是我的理由。调用原始的find-file-at-point
(defun find-file-at-point-with-line()
"if file has an attached line num goto that line, ie boom.rb:12"
(interactive)
(setq line-num 0)
(save-excursion
(search-forward-regexp "[^ ]:" (point-max) t)
(if (looking-at "[0-9]+")
(setq line-num (string-to-number (buffer-substring (match-beginning 0) (match-end 0))))))
(find-file-at-point)
(if (not (equal line-num 0))
(goto-line line-num)))

您可以使用bash脚本：
#! /bin/bash
file=$(awk '{sub(/:[0-9]*$/,"")}1' <<< "$1")
line=$(awk '{sub(/^.*:/,"")}1' <<< "$1")
emacs --no-splash "+$line" "$file" &
如果您为openline调用此脚本，则会收到错误消息，例如
Error: file.cpp:1046
你可以做到
openline file.cpp:1046
在第1046行打开file.cpp中的Emacs ..

我建议在emacs配置中添加以下代码：
(defadvice server-visit-files (before parse-numbers-in-lines (files proc &optional nowait) activate)
"looks for filenames like file:line or file:line:position and reparses name in such manner that position in file"
(ad-set-arg 0
(mapcar (lambda (fn)
(let ((name (car fn)))
(if (string-match "^\\(.*?\\):\\([0-9]+\\)\\(?::\\([0-9]+\\)\\)?$" name)
(cons
(match-string 1 name)
(cons (string-to-number (match-string 2 name))
(string-to-number (or (match-string 3 name) "")))
)
fn))) files))
)
到现在为止，您可以直接从命令行打开带有行号的文件，如下所示：
emacsclient filename:linenumber:position
P.S。我希望我的回答不会太迟。

另一个版本的Ivan Andrus'很好的查找文件建议，可以同时执行行+可选列号，正如您在节点和coffeescript错误中看到的那样：
;; Open files and go places like we see from error messages, i e: path:line:col
;; (to-do "make `find-file-line-number' work for emacsclient as well")
;; (to-do "make `find-file-line-number' check if the file exists")
(defadvice find-file (around find-file-line-number
(path &optional wildcards)
activate)
"Turn files like file.js:14:10 into file.js and going to line 14, col 10."
(save-match-data
(let* ((match (string-match "^\\(.*?\\):\\([0-9]+\\):?\\([0-9]*\\)$" path))
(line-no (and match
(match-string 2 path)
(string-to-number (match-string 2 path))))
(col-no (and match
(match-string 3 path)
(string-to-number (match-string 3 path))))
(path (if match (match-string 1 path) path)))
ad-do-it
(when line-no
;; goto-line is for interactive use

(forward-line (1- line-no))
(when (> col-no 0)

Emacs 25不再使用defadvice。 Refs
所以这里是更新为新语法的版本：
(defun find-file--line-number (orig-fun filename &optional wildcards)
"Turn files like file.cpp:14 into file.cpp and going to the 14-th line."
(save-match-data
(let* ((matched (string-match "^\\(.*\\):\\([0-9]+\\):?$" filename))
(line-number (and matched
(match-string 2 filename)
(string-to-number (match-string 2 filename))))
(filename (if matched (match-string 1 filename) filename)))
(apply orig-fun (list filename wildcards))
(when line-number
;; goto-line is for interactive use
(goto-char (point-min))
(forward-line (1- line-number))))))
(advice-add 'find-file :around #'find-file--line-number)
如果你从emacs（Cx Cf）内部调用打开文件，但是从命令行不再工作，这是有效的，当你从命令行调用它时，似乎emacs 25没有使用find-file而且我没有＆＃ 39;我知道如何调试这种事情。
答案 7 :(得分：3)
您谈到粘贴打开文件（我假设您的意思是在emacs内的查找文件提示符下）并且还从命令行执行某些操作。如果你想复制＆amp;粘贴，然后你需要做一些像伊万与defadvice显示的东西。如果您需要命令行中的某些内容，则可以执行以下操作。我从一年前使用emacs：// URI处理程序（在Firefox中使用）中做了一些改编：
将它放在您的.emacs文件中：
(defun emacs-uri-handler (uri)
"Handles emacs URIs in the form: emacs:///path/to/file/LINENUM"
(save-match-data
(if (string-match "emacs://\\(.*\\)/\\([0-9]+\\)$" uri)
(let ((filename (match-string 1 uri))
(linenum (match-string 2 uri)))
(while (string-match "\\(%20\\)" filename)
(setq filename (replace-match " " nil t filename 1)))
(with-current-buffer (find-file filename)
(goto-line (string-to-number linenum))))
(beep)
(message "Unable to parse the URI <%s>" uri))))
然后在你的路径中创建一个shell脚本（我称之为'emacsat'）：
#!/bin/bash
emacsclient --no-wait -e "(emacs-uri-handler \"emacs://$1/${2:-1}\")"
DOS批处理脚本看起来很相似，但我不知道如何做默认值（虽然我很确定你可以这样做）。
如果您想要与Firefox集成，请参阅How to configure firefox to run emacsclientw on certain links?以获取更多说明。

我稍微重写了find-file-at-point函数。
