Subject: Expansion of #$ in byte-compiled files
Date: Thu, 3 Sep 2015 19:53:27 +0000 (UTC) [thread overview]
Message-ID: <1668732705.1162011.1441310007202.JavaMail.yahoo@mail.yahoo.com> (raw)
Please correct me if I am not right here, but it appears that in byte-compiled files (don't always?) expand #$ to the current elisp file name.
I wrote a module containing the following code:
(message "x: %S" #$)
When I load this module using load-file of the .el file adds a line to the *Message* buffer
Loading /user/michael/x.el (source)...
x: "/user/michael/x.el"
Loading /user/michael/x.el (source)...done
I then byte-compile the module, use load-file on the .elc file, and now I get
Loading /user/michael/x.elc...
x: nil
Loading /user/michael/x.elc...done
This causes all loading ELPA/MELPA packages to generate the following error during initialization:
(wrong-type-argument stringp nil)
because of the following generated line in the package autoloads script:
(add-to-list 'load-path (or (file-name-directory #$) (car load-path)))
and then the autoloads file gets byte-compile'd when installed.
This is with the latest Cygwin version with the W32 GUI:
GNU Emacs 24.5.1 (x86_64-unknown-cygwin)
of 2015-06-23 on desktop-new
Are others seeing the issue? Is this cygwin specific? I will try this out on a Linux latest dev version as soon as I can.
