        * essd-r.el (ess-find-newest-R): New defun, to find the newest

        (ess-check-R-name): New defun to check that
        inferior-R-program-name points to an executable.
        (R-newest): Use ess-find-newest-R defun.
        (ess-find-newest-R): Add message whilst searching.

        * ess-site.el: Call ess-check-R-name once, upon startup.

        * ess-eldoc.el (ess-eldoc): Use ess-local-process-name rather than

        * ess.el (ess-write-to-dribble-buffer): patch from Markus Triska
        <markus.triska@gmx.at>.  Most importantly, deactivate-mark is set
        to nil so that any active region is not affected.  (Without this,
        in transient-mark-mode in GNU Emacs, highlighting of the region is
        lost when moving over chunks, and M-h (= mark-paragraph) on chunks
        doesn't work as expected.).  Now also use with-current-buffer.

2007-07-16  Stephen Eglen  <stephen@gnu.org>

        * ess-site.el (ess-sqpe-versions-created): Remove call to
        ess-newest-R, and instead allow R-newest to find the newest
        version of R.  This relies on a new devar, ess-r-versions-created,
        to store the other versions of R that were found when ess-site was
        loaded.


        * essd-r.el (R-newest): New defun.  First time it is called, try
        to find the newest version of R.
        (ess-newest-r): Just return the name of the newst version of R;
        let R-newest do the fset call.

        * ess-mode.el (ess-function-pattern): Add defvar to quieten byte
        compiler.

        * ess-help.el (ess-help-mode): No need to make
        ess-local-process-name buffer local; that's done elsewhere.
        * ess-inf.el (ess-execute):  Ditto.


        * ess-cust.el: Update many doc strings, and change some vars from
        defcustom to defvar.

2007-07-14  Stephen Eglen  <stephen@gnu.org>

        * essd-r.el (ess-find-newest-date): this-r should be a local var.

2007-07-13  Stephen Eglen  <stephen@gnu.org>

        * essd-r.el (ess-r-version-date): New defun, replacing
        ess-r-version-time as it returns the date stamp of R as a string
        rather than a time in seconds.
        (ess-find-newest-date): New defun, replacing
        ess-which-newest-date.


2007-07-11  Stephen Eglen  <stephen@gnu.org>

        * essd-r.el (ess-newest-r, ess-r-version-time, ess-which-newest):
        New defuns to find the newest version of R.

        * ess-eldoc.el: New file: add support for ELDOC in R buffers.

        * essd-r-args.el (ess-r-args-get): Use ?\( rather than using
        string-to-char.  Other small typo/doc fixes.


2007-06-29  Stephen Eglen  <stephen@gnu.org>

        * essl-sta.el (ordinary-insertion-filter): Delete this defun, it
        is also in ess-inf.el

        * ess-inf.el (inferior-ess-mode): Ensure font-lock-keywords-only
        is t (to fix bug in Emacs 22.1).  Other small changes:
        - using `member' rather than lots of `string=' comparisons.
        - replacing (if cond (progn ...)) by (when cond ...)
        - replacing:
        (make-local-variable some-var)
        (setq some-var val)
        with
        (set (make-local-variable some-var) val)


2007-06-27  Stephen Eglen  <stephen@gnu.org>

        * ess-site.el (ess-restore-asm-extns): use `when' rather than

        * essl-s.el (ess-toggle-S-assign-key): based on code by Seth Falcon;
        see ESS-help; TODO: a better 'toggle'

2006-03-17  Martin Maechler  <maechler@stat.math.ethz.ch>

        * ess-inf.el (ess-eval-paragraph-and-step): new;
                     (ess-eval-paragraph-and-go): dito.

        * ess-debug.el: added minimal documentation.  Removed cruft (this
        is cruft?).  copyright dates changed.

2006-02-09  Anthony Rossini <anthony.rossini@novartis.com>

        * ess-inf.el (ess-proc-name): better logic, cleanup.
        * ess-cust.el (ess-use-inferior-program-name-in-buffer-name): new variable.

        * ess-inf.el (inferior-ess): use new variable for buffername
        construction.

2006-02-09  Anthony Rossini <anthony.rossini@novartis.com>

        * essl-sas.el (SAS-mode-font-lock-keywords): font-lock in any case,
        also for dumb terminals

2006-01-20  Martin Maechler  <maechler@stat.math.ethz.ch>

        * essl-s.el (ess-add-MM-keys): add *-execute-screen-options

2006-01-06  Stephen Eglen  <stephen@gnu.org>

        * ess-install.el (ess-install-byte-compile): New defun.

        * msdos.el (msdos-minor-mode): Shouldn't msdos-minor-mode be
        defined earlier in the file?  Have not moved yet, as I cannot test
        on Unix.

        * ess-swv.el (ess-makePS): let* needed so that namestem can be
        used within definitions of let.

        * ess-inf.el (ess-bufs-in-frame): Defvar.

        * mouseme.el (mouse-me-execute): This function is broken, so I've
        made it just report an error [w32-shell-execute not present].

        * essddr.el (Rd-font-list): Move to top of document, before it is
        used in defuns.
        (Rd-active-mark): Put empty definition of defun before defining
        conditional on Emacs/Xemacs.  This silences the compiler.

        * essd-sp4.el (S+4, S+4-msdos): Replace
        (beginning-of-buffer) with (goto-char (point-min)).

        * essd-sp3.el (S+3-mode): Correct call to imenu (defun was
        broken).

        * essd-r.el (ess-rterm-versions-create): version-root should be a
        local variable.

        * ess.el (ess-write-to-dribble-buffer): Chnage insert-string to
        insert.

        string-to-number.

        * ess-cust.el (inferior-ess-primary-prompt): Add group, type.

        * essd-sp6.el (ess-s-versions-create): If ess-s-versions is nil, do

        not search for other versions of R.

        * essl-s.el (ess-fix-EQ-assign): slight improvement in regexp.

2005-11-24  AJ Rossini <blindglobe@gmail.com>

        * essd-r.el (R): cygwin, at least older versions, probably need to
        consider adding the --ess flag rather than the --no-readline,
        since we most likely are using Rterm and not R.

2005-11-22  Martin Maechler  <maechler@stat.math.ethz.ch>

        * essl-s.el (ess-dump-args-and-go): don't use (replace-string ..)

        new defuns have been loaded.

2005-11-07  AJ Rossini <blindglobe@gmail.com>

        * essa-sas.el (ess-sas-submit-pre-command): make sure that if
        there is no shell, i.e. (= (getenv "SHELL") nil), that we don't
        die.  This is true for old cygwins.

2005-10-12  Stephen Eglen  <stephen@gnu.org>

        * ess-toolbar.el (ess-add-icon-xemacs): Swap caddr for (nth 2)

        * essd-sp6.el (ess-s-versions-create): Use nth rather than car,
        cadr, caddr.  Much more readable and removes reliance on cl
        library for caddr.

        * essd-sp6.el (ess-s-versions-list): New variable.

        be added to ESS, similar to ess-r-versions-create.

2005-09-26  Martin Maechler  <maechler@stat.math.ethz.ch>

2005-09-02  Stephen Eglen  <stephen@gnu.org>

        * essd-r.el, ess-cust.el (ess-r-versions): Moved this variable
        from ess-cust.el.  (As a custom variable, it could be set after
        ess-site had been loaded, which is the time when its value is
        used.  Hence customized values were ignored.)
        (ess-r-versions-create): Apply unique to list of list of R
        binaries after stripping off the directory.  This prevents
        multiple entries with the same name occuring in the ESS -> Start
        Process -> Other menu.

2005-08-20  Martin Maechler  <maechler@stat.math.ethz.ch>

        * essl-sta.el (STA-syntax-table): allow // for comments

2005-08-03  Martin Maechler  <maechler@stat.math.ethz.ch>

        * ess-inf.el (inferior-R-1-input-help): '^ *help': do not trigger

        interactive specification.

2005-07-09  Martin Maechler  <maechler@stat.math.ethz.ch>

        * ess-mode.el (ess-beginning-of-function):

        * ess-mode.el (ess-R-function-pattern) etc: moved here from
        * ess-cust.el: greatly improved to also catch things like
                 "names<-.foo" <- function(.) { .... }

2005-07-08  Martin Maechler  <maechler@stat.math.ethz.ch>

        * ess-menu.el (ess-imenu-S-generic-expression): adding SetAs(..),
        but also e.g., setGroupMethod(..)

2005-07-05  Stephen Eglen  <stephen@gnu.org>

        * ess-help.el (ess-help-bogus-buffer-p): Document NR-FIRST, and
        reinstate code such that if NR-FIRST is nil, we search just the
        first 120 characters of a help buffer to see if it is bogus.  Have
        removed check for R text of the form "Help for topic `rlm'..."
        since this is caught elsewhere (see below).
        (ess-display-help-on-object): In R help buffers, if
        options("help.try.all.packages" = TRUE) then ?rlm will list which
        packages rlm is defined in.  This help buffer is not bogus, but
        instead is now relabelled *help[R](rlm in packages)*.

2005-07-05  Martin Maechler  <maechler@stat.math.ethz.ch>

        * ess-mode.el (ess-beginning-of-function): more helpful error
        message for finding the bug with A <-  # comment ...  function(.){..}


2005-06-23  Martin Maechler  <maechler@stat.math.ethz.ch>

        * essl-s.el (ess-fix-EQ-assign): extend to propose more s/=/<-/

2005-05-05  Stephen Eglen  <stephen@gnu.org>

        * ess-inf.el (ess-complete-filename): Add doc string.
        (inferior-ess-mode): Change order of functions added to
        comint-dynamic-complete-functions local hook.  Removed the value
        `t' from that hook to prevent the global value of that hook also
        being used.

2005-04-16  Stephen Eglen  <stephen@gnu.org>

        * ess-toolbar.el (ess-make-toolbar): If Emacs is running in a
        terminal, tool-bar-map is not defined (because tool-bars cannot be
        displayed) and hence we should not bother trying to make a
        tool-bar.

2005-04-15  A.J. Rossini  <blindglobe@gmail.com>

        * ess-swv.el: New file for Sweave, slightly modified from code
        done by David Whiting.

2005-04-08  Stephen Eglen  <stephen@gnu.org>

        * essl-s.el (R-editing-alist): Changed comment-start to #

        session.

2005-04-06  Martin Maechler  <maechler@stat.math.ethz.ch>

        * essl-s.el (ess-mode-hook): set *normal-*auto-fill-function, not

2005-03-03  Martin Maechler  <maechler@stat.math.ethz.ch>
  based on much from Kurt Hornik

        * ess-cust.el (ess-R-function-pattern): and ess-S-function-pattern
                instead of ess-function-pattern.
        * essl-s.el (S+common-cust-alist): set ess-function-pattern

        it's wrong to do this when a user had something like "--save" on
        startup.

2005-01-24  Martin Maechler  <maechler@stat.math.ethz.ch>

        * ess-emcs.el (ess-replace-regexp-in-string): New function,
        reapplied from Camm's patch.  This time the function is now used
        in all relevant customization-alists.  This function is needed
        since other elisp packages may also define
        replace-regexp-in-string.

2004-12-20  Stephen Eglen  <stephen@gnu.org>

        * ess-cust.el (ess-ms-slow): New variable.

        rather than within ess-multi.  (ess-multi is not run when
        ess-remote is used, and so prompt was not set for remote buffers
        running ESS processes.)

2004-11-24  Martin Maechler  <maechler@stat.math.ethz.ch>

        * essl-s.el (S-editing-alist): change comment-start from "#" to "##"

        * ess-inf.el (ess-multi): Fix bug: when inferior-ess-own-frame is
        non-nil, it should override the value of inferior-ess-same-window.

2004-10-28  Martin Maechler  <maechler@stat.math.ethz.ch>

        read-directory-name routine (dialog box when using mouse differs

2004-08-03  Stephen Eglen  <stephen@bushmills.inf.ed.ac.uk>

        * ess-mode.el (ess-mode-menu): Change function name for the
        default entry in "Start Process -> Other" submenu from R to nil.
        When it was set to R, this caused the R toolbar icon to not work
        since this menu entry was being found rather than the real menu
        entry for R.

        * ess-utils.el (ess-find-exec-completions): After checking that

        * ess-site.el (ess-versions-created): Tidy up the code for calling
        older versions of R and Sqpe.  Old version did not work on Unix,

        that variable is bound before using it.

        * ess-utils.el (ess-flatten-list): Standard defun needed for
        flattening a list.  Copied from lpr.el.

        * ess-toolbar.el (ess-use-toolbar): Default value should check if

        * ess-utils.el (ess-uniq-list): New defun for removing duplicate
        strings from a list.

        defuns to allow other versions of R to be called.

        * ess-cust.el (ess-r-versions): New variable to control which
        other versions of R are found.

        * ess-inf.el (ess-eval-linewise): Try again to get the point at
        the end of the S buffer after evaluation.  Previous attempt still
        didn't work, but I forgot that I had set
        comint-scroll-to-bottom-on-output.  This version should work even
        with that comint var set to nil.

2004-05-18  Stephen Eglen  <stephen@anc.ed.ac.uk>

        * ess-inf.el (ess-eval-linewise): If eob, remember to go to the

        (S+elsewhere, ESS-elsewhere): Add note in doc string to say these
        commands are obsolete and ess-remote should be used instead.

        * ess-site.el (ess-etc-directory): Move out of ess-cust.el and

        be started from menu.  Each menu item has a little tooltip help.

        (ess-make-toolbar-R-emacs,ess-make-toolbar-S-emacs): Check that
