A file of saved abbrev definitions is actually a file of Lisp code. The abbrevs are saved in the form of a Lisp program to define the same abbrev tables with the same contents. Therefore, you can load the file with
load (see How Programs Do Loading). However, the function
quietly-read-abbrev-file is provided as a more convenient interface. Emacs automatically calls this function at startup.
User-level facilities such as
save-some-buffers can save abbrevs in a file automatically, under the control of variables described here.
user option abbrev-file-name
This is the default file name for reading and saving abbrevs. By default, Emacs will look for
~/.emacs.d/abbrev_defs, and, if not found, for
~/.abbrev_defs; if neither file exists, Emacs will create
function quietly-read-abbrev-file \&optional filename
This function reads abbrev definitions from a file named
filename, previously written with
filename is omitted or
nil, the file specified in
abbrev-file-name is used.
As the name implies, this function does not display any messages.
user option save-abbrevs
nil value for
save-abbrevs means that Emacs should offer to save abbrevs (if any have changed) when files are saved. If the value is
silently, Emacs saves the abbrevs without asking the user.
abbrev-file-name specifies the file to save the abbrevs in. The default value is
This variable is set non-
nil by defining or altering any abbrevs (except system abbrevs). This serves as a flag for various Emacs commands to offer to save your abbrevs.
command write-abbrev-file \&optional filename
Save all abbrev definitions (except system abbrevs), for all abbrev tables listed in
abbrev-table-name-list, in the file
filename, in the form of a Lisp program that when loaded will define the same abbrevs. Tables that do not have any abbrevs to save are omitted. If
nil or omitted,
abbrev-file-name is used. This function returns
