  1. POEmacs lisp - problems with filename-string on win7
    text
    copied!<p>On Win7 with Emacs24 I encounter problems when Emacs programs want to open (pdf) files. The problems remain when I activate or deactivate openwith-mode. I either get a 'wrong-type-argument arrayp nil' message inside Emacs or Acrobat Reader is started but gives an error message 'can't open/find that file'.</p> <p>I tried to debug it and always ended up in files.el. It seems that the name of the pdf-file to be opened is constructed by concatenating the absolute filename and the file extension .pdf. However, the filename-string given to AcroRd32 appears to look like this:</p> <pre><code>AcroRd32 "c:\\absolute\file\name".pdf </code></pre> <p>This doesn't work on the command line either. I have to change it (manually) to</p> <pre><code>AcroRd32 "c:\\absolute\file\name.pdf" </code></pre> <p>or to</p> <pre><code>AcroRd32 c:\\absolute\file\name.pdf </code></pre> <p>to make it work. </p> <p>I don't know if this is considered a bug, or if it is a problem only for me. I tried to change the elisp code to something like</p> <pre><code>(format "%s" (concat absolute-filename file-extension)) </code></pre> <p>to get rid of those double-quotes, but to no avail. And anyway, I don't feel comfortable to mess around in a basic library like files.el, and its really hard to edebug that library since its invoked permanently. </p> <p>Maybe somebody encountered the same problem and found a solution?</p> <p>[I use GNU Emacs 24.0.91.1 (i386-mingw-nt6.1.7601) of 2011-11-22 on MARVIN.] </p> <p>PS 1 Test Case 1</p> <p>I get the following error message when I do M-x toggle-debug-on-error and then try to open a pdf file in dired: </p> <pre><code>Debugger entered--Lisp error: (wrong-type-argument arrayp nil) file-truename(nil) find-file-noselect-1(#&lt;buffer test.pdf&lt;4&gt;&gt; "~/.emacs.d/org/projects/sandbox/test.pdf" nil nil "~/.emacs.d/org/projects/sandbox/test.pdf" ((2816 7 . 27468) (16087 . 35227))) find-file-noselect("c:/Users/tj2/.emacs.d/org/projects/sandbox/test.pdf" nil nil nil) find-file("c:/Users/tj2/.emacs.d/org/projects/sandbox/test.pdf") dired-find-file() call-interactively(dired-find-file nil nil) </code></pre> <p>and the following message:</p> <pre><code>Openwith mode enabled find-file-noselect-1: Wrong type argument: arrayp, nil </code></pre> <p>Does it matter that my .emacs.d is really a windows symlink (mklink) to a Dropboxfolder?</p> <p>PS 2 Test Case 2</p> <p>here is the message I get in the maven-compile buffer, when doing C-c C-s (LilyPond-command-view) in a ,ly buffer:</p> <pre><code>-*- mode: compilation; default-directory: "~/.emacs.d/org/projects/sandbox/" -*- Compilation started at Tue Dec 20 09:16:28 AcroRd32 "c:/Users/tj2/.emacs.d/org/projects/sandbox/2test".pdf Compilation exited abnormally with code 1 at Tue Dec 20 09:16:35 </code></pre> <p>In the message buffer I find</p> <pre><code>Compilation exited abnormally with code 1 Error during redisplay: (invalid-regexp "Unmatched ( or \\(") </code></pre> <p>This error doesn't trigger the debugger, although I did M-x toggle-debug-on-error. </p>
