34.5 Saving Abbrevs
These commands allow you to keep abbrev definitions between editing
- M-x write-abbrev-file <RET> file <RET>
- Write a file file describing all defined abbrevs.
- M-x read-abbrev-file <RET> file <RET>
- Read the file file and define abbrevs as specified therein.
- M-x quietly-read-abbrev-file <RET> file <RET>
- Similar but do not display a message about what is going on.
- M-x define-abbrevs
- Define abbrevs from definitions in current buffer.
- M-x insert-abbrevs
- Insert all abbrevs and their expansions into current buffer.
M-x write-abbrev-file reads a file name using the minibuffer and
then writes a description of all current abbrev definitions into that
file. This is used to save abbrev definitions for use in a later
session. The text stored in the file is a series of Lisp expressions
that, when executed, define the same abbrevs that you currently have.
M-x read-abbrev-file reads a file name using the minibuffer
and then reads the file, defining abbrevs according to the contents of
the file. The function
quietly-read-abbrev-file is similar
except that it does not display a message in the echo area; you cannot
invoke it interactively, and it is used primarily in the .emacs
file. If either of these functions is called with
nil as the
argument, it uses the file name specified in the variable
abbrev-file-name, which is by default
That file is your standard abbrev definition file, and Emacs loads
abbrevs from it automatically when it starts up.
Emacs will offer to save abbrevs automatically if you have changed
any of them, whenever it offers to save all files (for C-x s or
C-x C-c). It saves them in the file specified by
abbrev-file-name. This feature can be inhibited by setting the
The commands M-x insert-abbrevs and M-x define-abbrevs are
similar to the previous commands but work on text in an Emacs buffer.
M-x insert-abbrevs inserts text into the current buffer after point,
describing all current abbrev definitions; M-x define-abbrevs parses
the entire current buffer and defines abbrevs accordingly.
