|

+Loading a file of Emacs Lisp code with @code{load-file} or
|
||||
+@code{load-library} (@pxref{Lisp Libraries}) can execute some of the
|
||||
+Lisp code in the file being loaded, so you should only load Lisp files
|
||||
+whose source you trust. However, some Emacs features can in certain
|
||||
+situations execute Lisp code even without your explicit command or
|
||||
+request. For example, Flymake, the on-the-fly syntax checker for Emacs
|
||||
+(@pxref{Top,,, flymake, GNU Flymake}), if it is enabled, can
|
||||
+automatically execute some of the code in a Lisp file you visit as part
|
||||
+of its syntax-checking job. Similarly, some completion commands
|
||||
+(@pxref{Completion}) in buffers visiting Lisp files sometimes need to
|
||||
+expand Lisp macros for best results. In these cases, just visiting a
|
||||
+Lisp file and performing some editing in it could trigger execution of
|
||||
+Lisp code. If the visited file came from an untrusted source, it could
|
||||
+include dangerous or even malicious code that Emacs would execute in
|
||||
+those situations.
|
||||
+
|
||||
+To protect against this, Emacs disables execution of Lisp code by
|
||||
+Flymake, completion, and some other features, unless the visited file is
|
||||
+@dfn{trusted}. It is up to you to specify which files on your system
|
||||
+should be trusted, by customizing the user option
|
||||
+@code{trusted-content}.
|
||||
+
|
||||
+@defopt trusted-content
|
||||
+The value of this option is @code{nil} by default, which means no file
|
||||
+is trusted. You can customize the variable to be a list of one or more
|
||||
+names of trusted files and directories. A file name that ends in a
|
||||
+slash @file{/} is interpreted as a directory, which means all its files
|
||||
+and subdirectories are also trusted. A special value @code{:all} means
|
||||
+@emph{all} the files and directories on your system should be trusted;
|
||||
+@strong{this is not recommended}, as it opens a gaping security hole.

|

+This variable lists those files and directories whose content Emacs should
|

|

+therein even without any explicit user request.
|

+For example, Flymake's backend for Emacs Lisp consults this variable

+and disables itself with an "untrusted content" warning if the file
|

+is not listed.

+Emacs Lisp authors should note that a major or minor mode must never set
