elisp: Abbrev Tables

 
 35.1 Abbrev Tables
 ==================
 
 This section describes how to create and manipulate abbrev tables.
 
  -- Function: make-abbrev-table &optional props
      This function creates and returns a new, empty abbrev table—an
      obarray containing no symbols.  It is a vector filled with zeros.
      PROPS is a property list that is applied to the new table (
      Abbrev Table Properties).
 
  -- Function: abbrev-table-p object
      This function returns a non-‘nil’ value if OBJECT is an abbrev
      table.
 
  -- Function: clear-abbrev-table abbrev-table
      This function undefines all the abbrevs in ABBREV-TABLE, leaving it
      empty.
 
  -- Function: copy-abbrev-table abbrev-table
      This function returns a copy of ABBREV-TABLE—a new abbrev table
      containing the same abbrev definitions.  It does _not_ copy any
      property lists; only the names, values, and functions.
 
  -- Function: define-abbrev-table tabname definitions &optional
           docstring &rest props
      This function defines TABNAME (a symbol) as an abbrev table name,
      i.e., as a variable whose value is an abbrev table.  It defines
      abbrevs in the table according to DEFINITIONS, a list of elements
      of the form ‘(ABBREVNAME EXPANSION [HOOK] [PROPS...])’.  These
      elements are passed as arguments to ‘define-abbrev’.
 
      The optional string DOCSTRING is the documentation string of the
      variable TABNAME.  The property list PROPS is applied to the abbrev
      table (Abbrev Table Properties).
 
      If this function is called more than once for the same TABNAME,
      subsequent calls add the definitions in DEFINITIONS to TABNAME,
      rather than overwriting the entire original contents.  (A
      subsequent call only overrides abbrevs explicitly redefined or
      undefined in DEFINITIONS.)
 
  -- Variable: abbrev-table-name-list
      This is a list of symbols whose values are abbrev tables.
      ‘define-abbrev-table’ adds the new abbrev table name to this list.
 
  -- Function: insert-abbrev-table-description name &optional human
      This function inserts before point a description of the abbrev
      table named NAME.  The argument NAME is a symbol whose value is an
      abbrev table.
 
      If HUMAN is non-‘nil’, the description is human-oriented.  System
      abbrevs are listed and identified as such.  Otherwise the
      description is a Lisp expression—a call to ‘define-abbrev-table’
      that would define NAME as it is currently defined, but without the
      system abbrevs.  (The mode or package using NAME is supposed to add
      these to NAME separately.)
