This is the CHANGES file of the IDLWAVE distribution, version 4.6 

The file covers only the changes for Revision 3.0 and later.  Earlier
changes are documented in the (obsolete) files idl.el and
idl-shell.el, available at 
http://www.strw.leidenuniv.nl/~dominik/Tools/idlwave.

Revision 4.6
============
   - Shell window more like xterm:
     - show as much output as possible
     - up and down arrows do history stuff (see new variable
       idlwave-shell-arrows-do-history). 
   - Routine info and help files updated to IDL 5.4
   - Support for the new IDL statements (SWITCH, BREAK, CONTINUE)
   - Bugfix for shell printing of identifiers with `!' and `.'
   - File name completion in strings in buffers, similar to the shell.
   - Fixed file name completion with a dash in file names.
   - Font-lock enhancements in structure definitions: Structure name
     and tag names.
   - END is replaced by ENDIF etc already when indenting a line with TAB.
   - Fixed bug with parsing of routine definition if comment lines are
     scallered between continuation lines.
   - `idlwave-close-block' and `idlwave-abbrev-change-case'
     interaction bug fixed.
   - Routine info and source lookup switch to INIT automatically when
     the cursor is in keyword section of an OBJ_NEW call.
   - Fixed BUG with getting system variable info from the Shell under
     IDL5.2 and earlier.  Used to produce a compilation error, now
     just silently fails.
 

Revision 4.5
============
   - Bug fixed with structure parsing in CLASS__define procedures.

Revision 4.4
============
   - IDLWAVE understands inheritance in all important contexts.
   - Completion of system variables and their tags.
   - Completion of class structure tags on "self" variables.

Revision 4.3
============
   - The IDL procedure "BEEP" works in the IDLWAVE Shell
   - Fixed bug with dedicated shell frame display under Emacs
     (patch from Stein Vidar Hagfors Haugan <shaugan@esa.nascom.nasa.gov>)

Revision 4.2
============
   - Fixed bug with context-help when at end-of-buffer.
   - Ambiguous kwd abbrev and non-existent in online help kwd
     now ring the bell.
   - Toggling the toolbar causes a redraw-frame on Emacs (21 only).
   - Allow for space between a function and `('.
   - Forcing completion type with prefix arg to M-TAB fixed in the shell.
   - Fixed bug when exiting shell with *idl* as the only window.
   - The class of object "self" is assumed of be the current routines class.

Revision 4.1
============
   - Fixed bug in which unresolved routines could shadow catalog entries.
   - Fixed the incorrect installation instructions in README.hlp.
   - Online help for non-system stuff makes use of the DocLib file header.
   - Abbreviated keywords are treated correctly for online help.
   - Source files displayed as online help can be fontified
     (off by default, see variable `idlwave-help-fontify-source-code').
   - Multiple definitions of a routine in one file count as shadowing.
   - Facility to send single characters to interact with GET_KBRD (see manual)
   - The shell defines a system variable !IDLWAVE_VERSION, which can
     be used by a program to detect if it is running under Emacs or not.
   - More efficient way of querying the shell for routine info.
   - Fixed bug in get_rinfo -> 10 mode keywords recognized.
   - Fixed bug with translation of help topics.
   - Fixed bug for completion context after continuation lines.
   - Fixed bug with Keyword insertion after `(' from Routine Info Window.

Revision 4.0
============
   - Fast and accurate IDL online help.  Two additional files need to
     be installed, they are not part of the standard distribution.
     Help is triggered with `M-?', and by clicking with mouse-3 on
     items in the Routine Info buffer or in *Completions*.
   - Global IDL namespace analysis to produce a list of routines
     with definitions in several files.
   - Clicking on a keyword in the routine-info buffer inserts
     the keyword in the buffer from which `C-c ?' was called.
   - More intelligent completion in OBJ_NEW calls.
   - Class completion after PRO and FUNCTION.
   - Abbrev expansion in the shell.
   - `idlwave-pad-keywords' can also have a value `keep'.
   - `idlwave-scan-all-buffers-for-routine-info' can also have value
     `current' to scan only the current buffer but no other buffers. 

Revision 3.15
=============
   - Printing expressions while execution is halted can now also
     access all levels on the calling stack.
   - Padding of long operators (like `->') is now possible.  The
     object arrow `->' has been added to the defaults - when
     `idlwave-do-actions' is non-nil, `->' will have at least one
     space before and after it.
   - Code templates now respect settings of `idlwave-abbrev-change-case'
     and `idlwave-reserved-word-upcase'.
   - Fixed bug with `idlwave-pad-keywords' in procedure method calls.
   - Fontification of keyword parameters works with embedded comments.

Revision 3.13
=============
   - Minor cleanup.

Revision 3.12
=============
   - 3 files had to be renamed, in order to get IDLWAVE included in the 
     Emacs distribution:
      - idlwave-shell.el   -> idlw-shell.el
      - idlwave-rinfo.el   -> idlw-rinfo.el
      - idlwave-toolbar.el -> idlw-toolbar.el
     When installing this version, make sure to remove the old
     idlwave-*.el files and update the autoload for `idlwave-shell'.

Revision 3.11
=============
   - Final cleanup before installing in the Emacs and XEmacs distributions.

Revision 3.10
=============
   - Fixed bug with `idlwave-shell-automatic-start'.
   - Fixed bug with the info files.

Revision 3.9
============
   - Exiting the shell does not kill the *idl* buffer.
   - Shell prompt pattern allows single whitespace before "IDL>"

Revision 3.8
============
   - Library scan implemented for Windows and MacOS.  On these systems 
     the search path need to be given in `idlwave-library-path'.
   - *Completions* window disappears after successful completion.
   - Fixed library scan bug with keywords in continuations line.

Revision 3.7
============
   - Completion of Object methods finalized.
   - Exiting the IDLWAVE shell now kills all associated buffers and
     the dedicated frame (if applicable).
   - Documentation finalized.  The printed documentation is 24 pages.
     Available online in Emacs (info), as postscript and HTML.

Revision 3.6
============
   - You can make IDLWAVE prescan library files for routine info.

Revision 3.5
============
   - Completion and Routine Info display now also work for object
     methods.
   - Completion and Routine Info display available in the IDLWAVE Shell.
   - Debugging Toolbar adapted for Emacs 21.
   - First draft of TeXInfo documentation.
   - Fixed bug with END expansion in CASE lists.

Revision 3.4
============
   - Fixed bug in Makefile with install-tags 
   - Fixed bug in with concat in XEmacs 21.x
   - Enforced FSF coding standards, to prepare for installation in
     main Emacs distributions.

Revision 3.3
============
   - `C-c ?' displays the calling sequence and keyword parameters of a
     routine.  Works for most builtin IDL routines, the routines you
     are currently editing, and the compiled routines in the idlwave-shell. 
   - `M-tab' completes procedure names, function names and keyword
     parameters in the buffer.  
   - New source file idlwave-rinfo.el contains the code for these new
     functions.

Revision 3.2
============
   - The cleanup after the idl process finishes is now reliable and gets
     called exactly once.
   - Toolbar code moved to a separate source file.
   - Fixed bug with `display-buffer' in Emacs 19.

Revision 3.0
============
   File idlwave.el
   ---------------
   - New maintainer Carsten Dominik <dominik@strw.leidenuniv.nl>
   - Renamed mode and all variables and functions.  The new prefix is
     `idlwave-' instead of `idl-'.  This was necessary to evade a name
     clash with the idl-mode defined in `cc-mode.el' which is part of
     X/Emacs 20 distributions.
   - Added Customize support.
   - New commands `idlwave-beginning-of-block' and `idlwave-end-of-block'.
   - New command `idlwave-close-block'.
   - The type of END at the end of the block is checked.
   - Font-lock enhancements.  Multi-level fontification based on the
     value of `font-lock-maximum-decoration'.  Reunified the different
     expressions for Emacs and XEmacs.
   - `idlwave-show-begin' check the correctness of the END statement.
   - `idlwave-surround' exception for `->'.
   - Better listing of abbreviations with `idlwave-list-abbrevs'.
   - Some general cleanup of the code.  Menu reorganized.
   - Both imenu (Emacs) and func-menu (XEmacs) are now supported.
   - Dropped support for Emacs 18 and hilit19.el.
   - Rewrite of the docstring for the Mode.  Made more compact, to
     make more people read it.  Too long parts moved to the Commentary.
   - Revision number jumps to 3.0 to synchronize with idlwave-shell.el.

   File idlwave-shell.el
   ---------------------
   - New maintainer Carsten Dominik <dominik@strw.leidenuniv.nl>
   - Renamed mode and all functions and variables to use `idlwave-' instead
     of `idl-' prefix. This was necessary to avoid a name clash with
     `idl-mode' which is defined in cc-mode.el.
   - Made the stop-line-overlay work for XEmacs as well.  Changed the
     associated face to 'highlight.
   - Breakpoint lines are highlighted with a glyph or a special face.
   - Debugging toolbar under XEmacs.
   - To get a special frame for the shell buffer, set the variable
     `idlwave-shell-use-dedicated-frame' to t, or call `idlwave-shell'
     with a prefix arg.  The hook suggested for in Revision 2.4 for
     the same purpose probably still works, but is no longer recommended.
   - Changed the default `idlwave-shell-use-truename' to nil, since we ensure
     now internally to not visit the same file twice under different names.
   - Menu reorganized.
   - Implemented a number of new commands.  Check the "Debug" menu.
