elisp: Primitive Indent

 
 31.17.1 Indentation Primitives
 ------------------------------
 
 This section describes the primitive functions used to count and insert
 indentation.  The functions in the following sections use these
 primitives.  Size of Displayed Text, for related functions.
 
  -- Function: current-indentation
      This function returns the indentation of the current line, which is
      the horizontal position of the first nonblank character.  If the
      contents are entirely blank, then this is the horizontal position
      of the end of the line.
 
  -- Command: indent-to column &optional minimum
      This function indents from point with tabs and spaces until COLUMN
      is reached.  If MINIMUM is specified and non-‘nil’, then at least
      that many spaces are inserted even if this requires going beyond
      COLUMN.  Otherwise the function does nothing if point is already
      beyond COLUMN.  The value is the column at which the inserted
      indentation ends.
 
      The inserted whitespace characters inherit text properties from the
      surrounding text (usually, from the preceding text only).  
      Sticky Properties.
 
  -- User Option: indent-tabs-mode
      If this variable is non-‘nil’, indentation functions can insert
      tabs as well as spaces.  Otherwise, they insert only spaces.
      Setting this variable automatically makes it buffer-local in the
      current buffer.
