I am unable to access remote files in my usual way:
C-x C-f

and am thrown this error:
Wrong Type Argument: listp, [[server]:[path][file]
I'm not even sure how to debug this further.
any help is appreciated.

Check what command C-x C-f is bound to (use C-h k). Is it the standard binding find-file? (It doesn't sound like it.)
If not, check its interactive spec. The command is expecting to receive a list as argument, and it is instead receiving (what looks like) a string.
This is the interactive spec of find-file:
(interactive
(find-file-read-args "Find file: " (confirm-nonexistent-file-or-buffer)))
If the interactive spec of your C-x C-f command, like this one, has a non-string as its argument, then you can either M-x debug-on-entry THE-FUNCTION, where THE-FUNCTION is the function called for the argument (find-file-read-args, in the case of find-file), or wrap that argument so that the debugger is invoked:
(progn (debug) (WHATEVER-WAS-THERE-BEFORE))
Either way, the debugger will open for the interactive part of reading the file name, and you can walk through the debugger to see what goes wrong.
But probably you can figure out the problem just by inspecting the code -- the interactive spec. The argument to your command (whatever it is) is expected to be a list, but it is a string.
I would start by seeing what happens with a local file name. Do you get an error for that too?
Another thing I notice is that the error reports an extra [, in front of what you say you typed as input. That should provide a clue too. What you think it is reading is not what it has read.
I would like to use elisp to tokenize the following:
variable := "The symbol \" delimits strings"; (* Comments go here *)
as:
<variable> <:=> <The symbol \" delimits strings> <;>
based on the information from the buffer's syntax-table.
I have the symbol-table setup appropriately and am currently using the following function which operates correctly except for the string constant (either returns token or nil if point is not at an identifier or one of the operators in the regex).
(defun forward-token ()
(forward-comment (point-max))
(cond
((looking-at (regexp-opt '("=" ":=" "," ";")))
(goto-char (match-end 0))
(match-string-no-properties 0))
(t (buffer-substring-no-properties
(point)
(progn (skip-syntax-forward "w_")
(point))))))
I am an elisp novice, so any pointers are appreciated.
I don't think your skip-syntax-forward use is correct for strings.
I think you need to add a cond clause like this:
((looking-at "\"")
(let* ((here (point)) (there (scan-sexps here 1)))
(goto-char there)
(buffer-substring-no-properties
(1+ here) (1- there))))
to handle string literals.
There's process output that needs to be parsed per line, into structs.
sug skProc strutils.capitalize proc (string): string{.noSideEffect.}
sug skProc strutils.quoteIfContainsWhite proc (string): string
sug skProc system.gorge proc (string, string): string
sug skProc system.of proc (T, S): bool{.noSideEffect.}
sug skProc system.definedInScope proc (expr): bool{.noSideEffect.}
sug skIterator system.items iterator (cstring): char{.inline.}
sug skProc system.ord proc (T): int{.noSideEffect.}
This data is inside a buffer. So how do I read each line and pass it
to a function which returns a parsed representation and collect all
lines in the end?
EDIT: The code for parsing the lines (not debugged):
(defstruct nimrod-sug type namespace name signature)
(defun nimrod-parse-suggestion-line (line)
(let ((split (split-string line "[\t\n]")))
(make-nimrod-sug
:type (nth 1 split)
:namespace (first (split-string (nth 2 split) "\\."))
:name (second (split-string (nth 2 split) "\\."))
:signature (nth 3 split))
With some minor changes to the parser:
(defun nimrod-parse-suggestion-line (line)
(destructuring-bind (_ type fn &rest sig) (split-string line "[[:space:]]+" t)
(make-nimrod-sug :type type
:namespace (first (split-string fn "\\."))
:name (second (split-string fn "\\."))
:signature (apply 'concat sig))))
Assuming the name of the buffer is *output*, you can parse it like so:
(with-current-buffer "*output*"
(mapcar 'nimrod-parse-suggestion-line
(split-string (buffer-string) "[\r\n]" t)))
; => ([cl-struct-nimrod-sug "skProc" "strutils" "capitalize" "proc(string):string{.noSideEffect.}"] ...)
If you're currently visiting the output buffer, you won't need the with-current-buffer wrapper.
Very often, compilations errors are displayed with the file:line syntax.
It would be nice to copy-paste this directly to open the file at the right line.
Emacs already has some mode to handle this in buffers (compile-mode, iirc), but I would like to have this available from the shell command line, since I use the standard shell most of the time outside of emacs.
Any idea how to tweak emacs to learn file:line syntax to open file at line line? (obviously, if file:line really exists on disk, it should be opened preferably)
You can do this using emacsclient. e.g. to open FILE at line 4, column 3 in a new frame:
emacsclient +4:3 FILE
Leave off the :3 to simply open the file at line 4.
I have the following in my .emacs, but I haven't found it as useful as I thought it would be.
;; Open files and goto lines like we see from g++ etc. i.e. file:line#
;; (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
(filename &optional wildcards)
activate)
"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]+\\):?$" filename))
(line-number (and matched
(match-string 2 filename)
(string-to-number (match-string 2 filename))))
(filename (if matched (match-string 1 filename) filename)))
ad-do-it
(when line-number
;; goto-line is for interactive use
(goto-char (point-min))
(forward-line (1- line-number))))))
I suggest to add following code in your emacs config:
(defadvice server-visit-files (before parse-numbers-in-lines (files proc &optional nowait) activate)
"looks for filenames like file:line or file:line:position and reparses name in such manner that position in file"
(ad-set-arg 0
(mapcar (lambda (fn)
(let ((name (car fn)))
(if (string-match "^\\(.*?\\):\\([0-9]+\\)\\(?::\\([0-9]+\\)\\)?$" name)
(cons
(match-string 1 name)
(cons (string-to-number (match-string 2 name))
(string-to-number (or (match-string 3 name) "")))
)
fn))) files))
)
by now you can open file with a line number right from command line like this:
emacsclient filename:linenumber:position
P.S. I hope i'm not too late with my answer.
And here is my go at it. Calls the original 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)))
You can use a bash script:
#! /bin/bash
file=$(awk '{sub(/:[0-9]*$/,"")}1' <<< "$1")
line=$(awk '{sub(/^.*:/,"")}1' <<< "$1")
emacs --no-splash "+$line" "$file" &
If you call this script for openline and you get an error message, e.g.
Error: file.cpp:1046
you can do
openline file.cpp:1046
to open the file.cpp in Emacs at line 1046..
Another version of Ivan Andrus' nice find-file advice which does both line + optional column number, as you see in node and coffeescript errors:
;; Open files and go places like we see from error messages, i e: path:line:col
;; (to-do "make `find-file-line-number' work for emacsclient as well")
;; (to-do "make `find-file-line-number' check if the file exists")
(defadvice find-file (around find-file-line-number
(path &optional wildcards)
activate)
"Turn files like file.js:14:10 into file.js and going to line 14, col 10."
(save-match-data
(let* ((match (string-match "^\\(.*?\\):\\([0-9]+\\):?\\([0-9]*\\)$" 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
(goto-char (point-min))
(forward-line (1- line-no))
(when (> col-no 0)
(forward-char (1- col-no)))))))
Emacs 25 does not use defadvice anymore. Refs.
So here is the version updated to the new syntax:
(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]+\\):?$" filename))
(line-number (and matched
(match-string 2 filename)
(string-to-number (match-string 2 filename))))
(filename (if matched (match-string 1 filename) filename)))
(apply orig-fun (list filename wildcards))
(when line-number
;; goto-line is for interactive use
(goto-char (point-min))
(forward-line (1- line-number))))))
(advice-add 'find-file :around #'find-file--line-number)
This works if you call open file from inside emacs (C-x C-f), but not works anymore from command line, it seems that emacs 25 is not using find-file when you call it from command line and I don't know how to debug this kind of thing.
You talk about pasting to open a file (I assume you mean at a find file prompt inside of emacs) and also doing something from the command line. If you want to copy & paste then you need to do something like what Ivan showed with the defadvice. If you want something from the command line you can do the following. I've adapted this from something I did a year ago with an emacs:// URI handler (for use from within Firefox):
Put this in your .emacs file:
(defun emacs-uri-handler (uri)
"Handles emacs URIs in the form: emacs:///path/to/file/LINENUM"
(save-match-data
(if (string-match "emacs://\\(.*\\)/\\([0-9]+\\)$" 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))))
and then create a shell script in your path (I called mine 'emacsat'):
#!/bin/bash
emacsclient --no-wait -e "(emacs-uri-handler \"emacs://$1/${2:-1}\")"
A DOS batch script would look similar, but I don't know how to do default values (though I'm pretty sure you can do it).
See How to configure firefox to run emacsclientw on certain links? for further instructions if you want to integrate with Firefox, too.
To return42's code, added column number support, and cleaned up case where column number is present, and line number is sought.

I made a little rewrite of the find-file-at-point function.
If there is a line number match, the file will be opened within an other window and the courser will be placed in this line. If no line number match, do what ffap normally does ...
