,----[ C-h f list-load-path-shadows RET ]
| list-load-path-shadows is an interactive autoloaded Lisp function in
| `shadow.el'.
|
| (list-load-path-shadows &optional STRINGP)
|
| Display a list of Emacs Lisp files that shadow other files.
|
| If STRINGP is non-nil, returns any shadows as a string.
| Otherwise, if interactive shows any shadows in a `*Shadows*' buffer;
| else prints messages listing any shadows.
|
| This function lists potential load path problems. Directories in
| the `load-path' variable are searched, in order, for Emacs Lisp
| files. When a previously encountered file name is found again, a
| message is displayed indicating that the later file is "hidden" by
| the earlier.
|
| For example, suppose `load-path' is set to
|
| ("/usr/gnu/emacs/site-lisp" "/usr/gnu/emacs/share/emacs/19.30/lisp")
|
| and that each of these directories contains a file called XXX.el. Then
| XXX.el in the site-lisp directory is referred to by all of:
| (require 'XXX), (autoload .... "XXX"), (load-library "XXX") etc.
|
| The first XXX.el file prevents Emacs from seeing the second (unless
| the second is loaded explicitly via `load-file').
|
| When not intended, such shadowings can be the source of subtle
| problems. For example, the above situation may have arisen because the
| XXX package was not distributed with versions of Emacs prior to
| 19.30. An Emacs maintainer downloaded XXX from elsewhere and installed
| it. Later, XXX was updated and included in the Emacs distribution.
| Unless the Emacs maintainer checks for this, the new version of XXX
| will be hidden behind the old (which may no longer work with the new
| Emacs version).
|
| This function performs these checks and flags all possible
| shadowings. Because a .el file may exist without a corresponding .elc
| (or vice-versa), these suffixes are essentially ignored. A file
| XXX.elc in an early directory (that does not contain XXX.el) is
| considered to shadow a later file XXX.el, and vice-versa.
|
| Shadowings are located by calling the (non-interactive) companion
| function, `load-path-shadows-find'.
