$Revision: 4.13 $
The original TODO list (nothing fixed there yet):
===========================================================
The following things need to be fixed. In a very rough order of priority.
* (DS) M-RET in *S* doesn't work properly with multi-line inputs.
* (DS) Typing C-c C-d in an S-mode buffer can read the wrong file
(apparently the wrong value of S-directory is used.)
* (DS) Maybe S-eval-region should do S-view-at-bottom, too
* (DS) It would be nice to interpret a nil value of S-directory as the
default directory.
* (DS) Add a predicate to control when S-object-list is dumped. It would
be nice to dump this only if an assignment has taken place or the
search list has changed.
* (DS) C-u -1 C-c C-x C-c C-o produces odd results
* (DS) Automate inferior-S-send-input to delay sending to the S process
until a complete command has been typed. (I.e. when presented with
an incomplete command, RET behaves like LFD). If this is done,
multi-line commands will always get into the history as one entry.
* (DS) The menus need finetuning, and a binding to a keyboard key.
* (DS) Need to decide on a sensible policy on csh-like history references.
At the moment, expanding such references is only possible from the
menu.
* (DS) Need a keystroke to kill an edit buffer *and* the associated file.
* (DS) Need a function to copy an object to a new object *and* copy
it's source file to a new source file, modifying the target of
the assignment.
* (DS) Debugging support, through trace() and tprint()
* (DS) Modify S-beginning-of-function so that, with arg n, will move out
n layers of nested functions. Wiht C-u arg, move to outermost
function definition
* (DS) Rewrite the S-command and S-eval-visibly functions to use
transaction queues (so that we can really have S running in the
background) This is a big job.
=============================================================
Here is the new set (a start for S-mode 5.0).
NOTE: Not all of these are clean OR are even consistent.
--------------------------------------------
* (KH) Fix indentation for "{" in the GNU style...
Kurt> * What I also find frustrating is that the GNU style does
Kurt> not get the indentation of `{' in:
Kurt> fun <- function(x, y, z) {
Kurt> right (in fact, the results of hitting TAB on the second
Kurt> line seem to vary). But it is not important.
* (KH) It may be worth while replacing
("^[>+]" . font-lock-keyword-face)
in R-inf-font-lock-keywords by
("^[RS]?[>+]" . font-lock-keyword-face)
(or perhaps something even better assuming the coexistence of processes
called R, S, S<something> on a system with the corresponding prompts.
(MM) Yes, add "S4" to this list to get something like
("^[RS]?[1-9.]?[>+]" . font-lock-keyword-face)
is not quite correct, since it includes ".3>" buth should rather
"R0.50>".
* (KH) In R at least, asking for deletion of a file after loading it with C-c
C-l does not make sense.
(MM) Yes! -- this has been a real pain, especially when the file was
version-controlled, it sometimes has just been deleted w/o asking !
* (KH) Also, there is no support for an Emacs-specific startup file. This is
not really important right now, I think, but anything based on comint
and term should support that.
(Tony, if you look at my R-inf.el, you'll notice that some effort goes
into doing the right thing with output from startup args and files.)
* (KH) The function S-complete-object-name() in S-inf.el currently
returns
(or (comint-dynamic-simple-complete pattern components) 'none)
with the comment `always return a non-nil value to prevent history
expansions'. Do you have an idea what that means?
Is there any good reason to break the Emacs/Comint convention that a
completer should return a non-nil value only if it did successfully
complete?
The specific reason why I ask is the following:
S-inf does
(setq comint-dynamic-complete-functions
'(S-complete-filename
S-complete-object-name
comint-replace-by-expanded-history))
I don't care about the last and prefer
(setq comint-dynamic-complete-functions
'(S-complete-object-name
comint-dynamic-complete-filename))
Note the reversed order of filename and object name completions. I
think it makes more sense that way, because if I have the file
`anthony.dat' in my current dir and do
anthony <- read.table("anthony.dat")
then typing `ant TAB' at the R prompt should complete to `anthony'
as an object name, as I can always force the filename in the current
dir by `./ant TAB'.
However, as S-complete-object-name() always returns a non-nil value,
the comint file name completion simply does not happen (well
... that's at least what I think is the case ... but then also, what
is the point to have comint-replace-by-expanded-history() in the
list of completers, when it definitely will never be called
... hmmm.)
Please let me know what you think. My suggestion would be to simply
change the last 2 lines of the code for S-complete-object-name() to
(comint-dynamic-simple-complete pattern components))))
and set comint-dynamic-complete-functions as I do :-)
Well ... what I said was not quite right, as S-complete-object-name
also tries to do something about `./ant RET'. In any case, please
let me know what you think.
* (AJR) Need an AUTOCONF for configuring Makefile, etc...
* (AJR) Move S-extras into the mainstream distribution files and as an
S-site example.
* (KH) So, need a "create-debian" entry in the Makefile.
* (KH) MINOR REMARK: Currently, we have American and English spelling
together. If we want to change this, please add it to the TODO list.
* (KH) MINOR REMARK: Some of the doc strings are not o.k. (first
sentence longer than one line ). We eventually need to fix this,
but perhaps not for 4.9.
* (KH) Btw, why not have `M-x vista' too?
* (KH) MAJOR REMARK I:
The code for getting the `right' history file does not work. E.g.,
when I start R and XLS in the same directory, they both use
.Rhistory.
For a possible solution, see the novel below.
* (KH) MAJOR REMARK II:
The code
(condition-case ()
(load S-object-name-db-file)
(error
(message "%s does not exist. Consider running S-create-object-name-db."
S-object-name-db-file)
(ding)
(sit-for 1)))
in S.el causes several problems.
First, it produces an error in the byte-compilation process. I
noticed that you put an empty S-namedb.el in the distribution, but
that does not help if `nil' is not in the default load path
(because then the current directory is not searched), which I think
is the default.
Second, there should obviously be different namedb for R and S.
(What I really mean is that the setting of S-object-name-db must be
a function of the implementation [have we officially decided on
using `dialect'?] used. Hence, the right thing most likely is to
execute the code not when loading S.el, but when it is clear which
process is started (assuming we have different namedb's for each
dialect).
This could probably be as late as before inferior-S-mode-hook, but I am
not sure.
(Note: currently this is not a problem for me, because I only have R,
but what does Martin do?)
* (KH) NOVEL:
So I spent several hours yesterday trying to figure out the right way of
solving our problems with local variables, in particular because Martin
explicitly asked me to do (only to find that the next morning Tony had
already done something about it ...).
I think it is important to distinguish two kinds of variables that need
to be taken care of.
** One group is those variables which need to be known when the inferior
process is started (i.e., before the process and hence also its buffer
exist).
Such variables are
*) dialect (currently transmitted through S-proc-prefix)
*) program name (`R' might be on the load path)
*) program args (such as for `-v 10' for R)
*) program startup file (currently unused)
*) program history file (???)
** The other group consists of those which are not needed for startup,
but need to have the right buffer-local values in the interaction
buffer, such as
inferior-S-help-command
inferior-S-objects-command
etc.
The problem we have is that there is NO WAY of passing non-global
values to buffer-local variables in Emacs. Something like
(defun R ()
(let ((inferior-S-var value))
(inferior-S)))
does not set inferior-S-var to value in the interaction buffer if it is
local there. (Sort of static scoping.)
There are several possible solutions:
** Keep manipulating the global name space using setq-default, as b4
did. Of course, this is terrible, because it overrides defaults.
** Have one function which does something like
(cond
((eq S-dialect "R")
(setq ...))
((eq S-dialect "S4")
(setq ...))
(t
(ERROR)))
after calling make-local-variable() on the relevant variables, and wrap
the code into a function.
To add a dialect, users would need to to this in there inferior-S-mode
hook, or to advise/change this function.
** Have a list similar to S-style-alist with settings for the variables,
and a function which sets them. This is similar to the above, but keeps
the code for the function and the variables separate.
** Have a dialect specific hook, e.g.
inferior-S-<dialect>-mode-hook
** Keep manupulating a non-dialect-specific hook in the global name
space. This is what we currently do, and not `optimal' for the same
reason that using setq-default was not: If we think of inferior-S as
user function and S and R as simple wrappers, then calling these should
not modify the behavior of the generic function.
I think the KEY to a clean solution lies in the observation that there
is really only ONE variable needed in both steps (i.e., cranking up the
process and setting local variables in the interaction buffer), and that
is the information about the CURRENT DIALECT (which I think is currently
kept in `S-proc-prefix'. We need to ensure that this variable has the
right local value to be able to run a specific hook (or a simpler hook
as explained above), and that it starts the right process in the right
buffer etc.
To get that, we could either create a global variable, KEEP IT GLOBAL,
use let() in the wrappers, and assign to a local variable afterwards, or
(and I think this is the right thing to do) PASS THE DIALECT INFORMATION
AS AN ARGUMENT. I.e., we would have
(defun inferior-S (&optional dialect n)
...
[NOTE: I am not sure about the optional `n', and whether this is used.
I think that users might want to have
(defun R (&optional n) ...)
(defun S (&optional n) ...)
and we are safe to give inferior-S the interface we want because it is a
NEW function anyway. We could also have it prompt for all relevant
variables if given a prefix ...]
and have
(defun R (&optional n)
(interactive)
(inferior-S "R" n))
Now the function inferior-S has the information it needs. It can figure
out the `right' startup settings (history file, program name and args)
based on the dialect information in the generic pre-run hook and perhaps
a dialect-specific pre-run-hook, and PASS THE DIALECT INFORMATION ON to
the function S-multi() [or whatever it will be called]. I.e., it could
be
(defun S-multi (name &optional buffer dialect) ...)
S-multi can now do
(make-local-variable 'S-dialect)
(setq S-dialect (or dialect S-default-dialect))
and go on with the buffer-specific settings, again using the dialect
information as described above.
[Yes, there should be a default dialect which is used when inferior-S is
used directly. Perhaps naming would be better with global S-dialect and
inferior-S-dialect as the local one ...]
* (MM) My WISH:
I'm using ess-eval-region and friends very often.
If the region has leading TAB, I think the readline feature of R,
does a huge 'completion ...'
which can completely destray the whole evaluation.
((Try C-c C-f from within a function that has a bit of indentation,
and therefore leading TABS (unless you 'untabified' it).
))
Yes, I'll have to 'untabify' things before I send it to *R*, but it's a
pain, anyway.
One could do 'untabify' in ess-eval-region & ess-eval-visibly
in ess-inf.el.
But actually this is not quite correct,
since I may have real TABs in a string
nchar(" ") #-> 1 because it has one TAB
which should not be converted to spaces.
Hence my wish:
Write a function 'untabify-leading-white-space'
and apply it to the regions in ess-eval-region and ..-visibly.

5. essd-s+3.el
63 ;;(if (string= ess-version-running "S3")
This comment seems inconsistent with ess-version-running. I think it should be
;;(if (string= ess-version-running "S+3")
7. ess-object-name-db-file
ess.el line 775. Why is this EVIL? A nuisance I understand, but EVIL?
Does the database get built automatically when ess-mode is installed?
That would be the right thing to do. Then individual users wouldn't need
to know about it all.
10 ess.el lines 254-270
This is one of the things I put in my site-start.el. I think this is
too complicated. I think that when item 2 of this note is corrected (that is
run the ess-pre-run-hook before the things that depend on it) then the nil
value will work as advertised and the comment beginning with the word
" Alternatively," will become completely unnecessary.
(defvar ess-directory (file-name-as-directory (getenv "HOME"))
"*The directory ess is run from. It must end in a slash.
Provided as a default if ess-ask-for-ess-directory is non-nil.

run from.")
;; You can put something like:
;; (setq ess-directory (file-name-as-directory (concat (getenv "HOME") "/ess/")))

* (RMH) From smode.cmt (from the S4 package):
<-- AJR: some of these HAVE been done. -->
e. Problem
Working data will be in /usr/people/rmh/.Data
> !pwd
/disk5/rmh/smode
>
Reason:
.Data has not yet been created in /disk5/rmh/smode
Solution:
quit S, mkdir .Data, start again
Recommendation 1. Tell users in README to create .Data first.
Recommendation 2. Tell users in README about Info item
- User Option: S-directory
I for one always want the current buffer's working directory.
g. Question:
S-help does the following:
(S-command (format inferior-S-help-command object) tbuffer)
which seems to going through more work than is often necessary. When the
.Cat.Help subdirectory exists, why not just M-x find-file the help file?
2. S3, Splus 3.3, S4
e. S-inf-font-lock-keywords
In inferior-S-mode the expressions below are in the indicated faces:
> tmp <- 1:3 # > is in font-lock-keyword-face
# rest is font-lock-variable-name-face
tmp <- 1:3 # <- is in font-lock-reference-face
# rest is in default
I don't understand why.
>From the definitions in S-inf.el, I expected that there would be
no dependence on the presence or absence of the leading prompt ">".
In particular, I anticipated that <- would be in font-lock-reference-face
with or without the prompt.
f. S-inf-font-lock-keywords
I recommend adding several keywords to S-inf-font-lock-keywords
for S3 and Splus 3.3 as noted in the attached s3.el and splus.el.
g. Interesting glitch
While fixing C-c C-l for S4, I found the following:
>From the *scratch* buffer, both the commands
(S-command "source(\"junk.s\")\n" (get-buffer "*S-errors*"))
(S-command "source(\"junk.s\")\n")
work correctly when junk.s is ok.
The first one puts an error message in "*S-errors*" when junk.s has a
problem. But the second one loses the error message. I chose not to
investigate this further, since S-load-file uses the first form, and I
doubt any person would consider using the second.
3. S4 changes
a. S-mode.el [C-c C-l S-load-file]
;;; The S4 requires the fixes to
; S-dump-error-re
; S-parse-errors
; S-prompt-wait
;;; in my s4.el in order to respond correctly to syntax errors
;;; during S-load-file.
;;; Without these changes the system will freeze.
;;; (^G will clear the freeze, and ^XB *S-errors* will
;;; display the error message).
b. S.el and S-site.el
The variable S-version-running, defined in S.el, with the option to
revise in S-site.el, needs to be redefined to identify version 4.
Some of the items coded by S-version-running differ in Version 4.
b1. S-inf.el
(setq inferior-S-search-list-command "searchPaths()\n")
;;; This variable needs to depend on S-version-running.
;;; the function inferior-S-search-list-command should probably use
;;; inferior-S-search-list-command, but it actually has "search()\n"
;;; hard-wired in.
;;; inferior-S-objects-command is the same for version 4 as for version 3
b2. S.el
;;; inferior-S-help-command
;;; inferior-S-search-list-command
;;; S-dump-error-re
Add a new line
;;; inferior-S-objects-command
b3. S-help.el
;;; S-submit-bug-report needs to know about version 4 for a bug report
;;; to be useful.
c. Other changes in s4.el respond to changes in S4:
.Help is now __Help
Errors are now Problems
"Dumped" messages now become offers to Debug
Additional keywords should be fontified
d. I have placed S-namedb.el in $SHOME in my s4.el file. On further
reflection it should probably be in the $SHOME/library/emacs/
directory. Question, does it make sense for S-namedb.el to be
distributed in $SHOME/library/emacs as part of binary.*.tar.gz ?
* (RMH)
Rather than have the site installer change the name of the directory,
it should be possible to find it out automatically. Here is the
relevant code from my spread.frame package. It assumes the user
started up spread.frames by typing
M-x load-file "/path/name"
It then finds the directory associated with that path and goes from
there. Some similar trick should be doable when the user does a
M-x load-library "name"
(defun find-spread-frame-directory nil
"Locate directory in which spread.frame functions are stored."
(list-command-history)
(set-buffer "*Command History*")
(goto-char (point-min))
(search-forward "(load-file ") )
(goto-char (1+ (match-end 0)))
(setq beg (point))
(end-of-line)
(search-backward "/")
(goto-char (match-end 0))

(kill-buffer "*Command History*"))
* (daven@stille.llnl.gov (David Nelson))
Transcript mode is delightful, with one possible improvement. Quite
often, when I'm in the middle of a session, I'd like to insert a
comment in the transcript, preferably with a distinctive type face
like those provided by "font lock". Is there an easy way to do this
that I'm just missing?
(RMH's thought):
I'm writing to you rather than directly to daven@stille.llnl.gov
(David Nelson) because I'm not sure how to tell him to do the
following fix in .emacs or S-site.el because of the local variable
issue or if it even is the right fix.
I think the permanent answer should be for you to add the lines
(make-local-variable 'comment-start)
(setq comment-start "#")
(make-local-variable 'comment-start-skip)
(setq comment-start-skip "#+ *")
copied from S-mode.el to the files S-trans.el and S-inf.el (4.8
notation). But when I tried it out with M-x eval-expression in the
*S* buffer it didn't have the effect I anticipated.
I can't figure out the intent or meaning of the line
("^\\*\\*\\\*.*\\*\\*\\*\\s *$" . font-lock-comment-face) ; S-mode msg
from S-inf.el and S-trans.el
* (KH, 010897) Can we combine the inferior-ess font-lock-patterns for prompt
and input into one regexp? I.e., use
("^\\([a-zA-Z0-9 ]*[>+]\\)\\(.*$\\)"
(1 font-lock-keyword-face) ; prompt
(2 font-lock-variable-name-face keep t)) ; input
* (KH, 010897) Perhaps one could have an option to install the Info
files gzipped (as is default for e.g. Debian GNU/Linux).
* (RMH bad behavior)
I loaded ess-site from *shell* in directory ~/
Then I M-x S from that buffer. It asked me about starting S in ~/
The with in *shell* I cd /disk05/rmh and M-x S from *shell* again.
I think it should have attempted to start S from /disk05/rmh, but instead it
again asked me about starting S in ~/
* (AJR/RMH) make sure that font-lock stuff is properly set. (look into
file order, for example).

3. comments (beginning with #) are syntactically ignored by

ess-mode-syntax-table on line 733 of ess-vars.el.

* open questions
1. I think I want ess-mode-font-lock-keywords to be effective in
inferior-ess and in ess-transcript. That means to the user, the <-
and function and T and F will be highlighted as commands are typed
in.
2. That means to the ess-mode designer that the line
("^[a-zA-Z0-9 ]*[>+]\\(.*$\\)"
(1 font-lock-variable-name-face keep t)) ; input
is deleted from inferior-ess-font-lock-keywords.
3. Further it means that inferior-ess-font-lock-keywords should be
defined by adding additional definitions to
ess-mode-font-lock-keywords.
* harder questions
1. these keywords are hardwired. They should probably be put into
the *-customize-alist. In particular, S4 uses different keywords
for errors (problems) and so forth. It also uses different keywords
for the Help file (__Help instead of .Help). These are functional
differences, not just cosmetic differences where the font would be
wrong. See the comments in essd-s4.el (based on my original s4.el).
(just noticed, the current essd-s4.el has two ending pages.) It is
easy to make ess-mode work for S4 by overriding all the differences
(which is how s4.el works). It is harder to do it cleanly so the
same emacs session can be used for S4 and S3. Lots of currently
hardwired variables need to be moved to the *-customize-alist first.
xlispstat is quite differently structured, so I am sure that the
keywords and highlighting here will be either irrelevant or harmful
if applied directly. customization is needed for that generality as
well.
* comments
I'm confused? I've always gotten comment highlighting in
inferior-ess/S-mode. Or do you mean that it's not done in the right
place?
correct, it is not done where you think it is done (right place or
not). It is done by ess-mode-syntax-table for inferior and
transcript mode. It is not done at all for ess-mode. The font-lock
settings seems to be irrelevant.
* logic

Not so. The < > do not appear in font-lock-type-face.
* Hmm... I think that was the font that was to be used for the prompt.
Not so. The previous line is used for the prompt. This line seems
to be used to suppress font-lock control for all characters
following the prompt. Note that the (1 ...) is in the position
normally taken by the "." . I assume the keep makes it stay that
way for the rest of the line. I haven't bothered to read font.el to
figure this out.

they would. The corresponding modelines are
(ESS Transcript [] Font)
(ESS[R] [none] Font)
(ESS[S] [none] Font)
(Inf-ESS [S4]: run Font)
I don't know the original intent of the [] and [none], but I would
love to see the name of the buffer to which ^C^N is sending stuff.
* ^C^N goes to the wrong inferior process.
I opened test.r in the same directory as *R* and sent a line. It
went to the *S* buffer in a different directory and running the
wrong program. There needs to be a way for the system to ask me
which process to use. Also, it's default guessing system should
have guessed *R* based on the file name test.r.

and not even that, since that should be the result of C-c C-q, so
that we get a nice, uniform means of exiting.
(RS1) I don't believe the sas-log-mode suggestions were ever implemented.
In fact, sas-log-mode is not a default option anymore since there
are so many different applications that create .log files.
Instead, a few changes were made to sas-mode based on requests for syntax
highlighting of the .log. This feature can be toggled on and off
by F10. This temporarily turns on sas-mode for .log files so you will
not experience permanent extension collisions with other .log file
generating applications. Also, performance may be an issue.
Extremely long .log files (particularly those generated by macros
that involve alot of code-generation) can be extremely time-consuming
to fontify and lazy-locking is usually not an option due to the
complexity of the SAS regular expressions. Fast-locking may help a
bit, but font-locking of several minutes is not unheard of.
Also, the font-lock code was re-written to properly highlight either
a .sas or a .log file. See ess-sas-run-make-regexp below.
(RS2) Rich re-did sas-log-mode to use the font-locking from ESS[SAS] and
it seems to be working. The only caveat is that I found that
fast-lock is very slow for big .logs and I switched to lazy-lock
and it is much faster, however, I have problems toggling; usually,
after I turn it on, I can't turn it off; but, that's not so bad
with lazy-lock. Also, a new function creates transcript from
your .log, ess-sas-transcript
* (KH) Font-lock needs to be more intelligent about recognizing
reserved words in non-reserved contexts (such as in "strings").
(RS1) If this was a SAS problem, then problem has been fixed.
To turn on the new functionality,
(setq ess-sas-run-make-regexp nil)
(RS2) This is now the default and most known issues have been addressed;
even hanging then statements!
* (AJR) SAS indenting needs to be fixed.
(RS) I don't know if this was fixed, but I haven't had any problems
with indenting recently.
* (AJR) SAS fontlocking of comments needs to be fixed.
(RS) I believe this is done. We made a few changes, but the biggest
problem was that Emacs 19.34 was misbehaving.
See ess-sas-run-make-regexp above.
* (KH) explicit statement:
I have only one remark (one of my usual ones). I'd like to be able to
pass command line arguments to the inferior process when it is started.
This is currently not supported, and poses some difficulties with an
interactive prompt mechanism. (Also rules out my suggestion of using
C-u to force prompting for command line args.)
Hmm ... Perhaps we should have a variable (ess-inf-always-prompt-...)
to get around this problem?
* (RMH - SAS)
graphics are possible in two ways:
a. proc gplot; plot a*b / vpos=25;
b. goptions device=psfile;
filename gsasfile 'temp.ps';
and then use ghostview from another *shell* buffer.
autoexec.sas defines the departmental printers and turns off
overprinting. My autoexec.sas file is:
libname gdevice0 '/home/public/stat/gdevice0' ;
options noovp;
* (RMH - SAS) I have another proposal for font-lock in SAS-mode. I
think it will be easy, but I would like discussion first. My new
proposal is that
proc whatever
data myfile
%macro macname
and maybe a few others (including both the keyword and name of the
dataset or proc) be in font-lock-function-name-face
%include will be in font-lock-reference-face
Any other FIRST word in a statement will be in
font-lock-keyword-face
My reasoning is that the current laundry list is too long, and still
misses many keywords. The structure of the SAS language is
essentially keyword and arguments, so let's follow that.
(RS) Essentially done. The following statements are in
font-lock-reference-face: macro statements, PROC ...,
DATA, RUN, ENDSAS, and QUIT.
See ess-sas-run-make-regexp above.
* (Tobias Laatsch - SAS)
There seem to be some problems fontifying SAS Comments in ESS 5.0
Pre1. (I'm running xemacs 20.2 on AIX .)
Currently I recognized following problems:
1) Multi-line-comments are not fontified. (open comment "/*", some
lines of code, close comment "*/")
2) When typing / , " or ' in a comment-area, ESS fontifies the
whole line as normal code instead of comment.
3) Typing a '* in a comment-area fontifies the rest of the line as
string.
(RS) Fixed for /* */ style comments which are now handled by grammar
only. * ; and %* ; are still broken since they can't be
specified by grammar.
* (AJR)
Richard> I think of S-transcript-mode as identical to
Richard> inferior-S-mode except that the transmission is to the
Richard> same buffer in inferior-S-mode and to a different buffer
Richard> in transcript-mdoe. So I expect ^M (enter) to behave
Richard> normally for lines that begin with "> command" and "+
Richard> continuation".
Which is what my proposal does (send command, move to next prompt).
What needs to be modified is that currently, it moves to any next
prompt, including "+ ", rather than just to the next primary prompt --
it is smart enough to strip the "+ " as well from the whole command,
and collect the rest of the command line.

So, C-c C-r would only send lines beginning with
inferior-ess-primary-prompt (up to the last consecutive
inferior-ess-secondary-prompt), strip off the prompt, and ignore lines
which do not begin with prompts. Does this sound correct
(for C-c C-r)?
C-c C-n should be correct (comint-next-prompt).
* (KH/AJR)
I see. This is what the "help(\"%s\")\n" does.
Well, we have the following problem. The `new' interface to help()
I created is
help(topic, package = .package(), library = .lib.loc)
This allows you to get help on a topic (R object, ie fun or var or
whatever else is documented) in a package without loading it, via
help(topic, p = PKG)
I've eliminated the help(data = ) part, but there may soon be
another argument to search for keys ...
If we want people to be able to use the extended forms, we can
* use "help(%s)\n" for the format, which means they have to quote
special things as they would need to from the command line
* or do something smarter, such as
quote only if object does not contain ","
which appears to be the right thing.
What do you think?

The alternative sounds good. We might still want to quote the help
string in case it does not contain a `,', so that C-c C-v +
continues to work ...
* (RMH) His (Tom Cook's) sas-get-dataset is a very good idea and was
not in my proposal. I would do it using the same mechanism that
S-help uses to put the results of ?function into *help(function)*
buffer. It is a relative of ess-dump-object-into-edit-buffer. The
major difference is that there is no sense of editing the object and
sending it back to S. It is also a relative of the display of a
spred.frame, with the difference again that there is no sense of
editing the object.
I like the switch-to-sas* functions. I would like to generalize
them back to S. I think switch-to-S-source when entered from the
*S* buffer should go to the filename.s that was the most recent
sender of ^C^N or ^C^R.
Here is cook's sas-mode-map and how it fits with my essd-sas.el
"\C-c\C-i" 'indent-sas-statement) \t use recommended conventions
"\C-c\C-a" 'beginning-of-sas-statement) use
"\e\C-a" 'beginning-of-sas-proc) \M-\C-a

"\C-cd" 'sas-get-dataset) use
"\C-c\C-c" 'switch-to-sas-process-buffer) ^C^Z or ^C^Y
(RS) Can't comment on the S aspects, but you can now browse/edit a permanent
SAS dataset (provided the library definition appears in autoexec.sas)
with F9.

Here is my 5 line dir file from S-mode 4.8. It needs to be

This works correctly in Emacs 19.29. My memory says that when

* (RMH) buffer choice (questions for 5.1)

Then M-x XLS
XLS came up in the *R* buffer
Tried it again. This time I C-c q() from *S4*.
Then M-x S
S+3:3 came up in *S4* buffer.
This is obscure stuff. What really should happen?
Problem in inferior-ess: logic states that if the current buffer is
iESS or ESS-trans, and doesn't have an active process, use it,
instead of creating a new buffer. (AJR).
* (RMH)
* iESS [S+3] 5.0? 5.1?
'single quotes' are in regular font
"double quotes" are in quote font
This differs from ESS[S] mode in which both kinds of
quotes are in quote font.
Should be fixed in 5.0 if easy. Not obvious to me where
the problem is. The identical S-syntax-table is in use
in both iESS [S+3] and ESS[S]. The font-lock-keywords
don't seem to me to be the problem.
* (RMH)
Dumped problem in S+3
Here is an example of the Dumped font problem in S+3:
> "trellis.settings" + "x + z + abcdefghij + klmnopqrstuv"
Error in "trellis.settings" + "x + z + abcdefghij ..: Non-numeric first operand
Dumped
>
Note that the Error description from S+3 truncates the command and
adds the ".." to indicate the truncation. Part of what gets
truncated is the closing quotation mark. Hence everything from that
point on is still inside the opening quotation mark. Everything
includes the rest of the error description, the word "Dumped", the
prompt on the next line, and all succeeding commands. I normally go
back and edit the line by adding the closing quote in front of the
prompt
Dumped
">
I would love for iESS [S+3] to monitor the word "^Dumped" and make sure the
font is back to regular.
* On the Dumped ".. font problem
I have an answer that I am uncomfortable with.
The problem:
Error in "trellis.settings" + "x + z + abcdefghij ..: Non-numeric
first operand
Dumped
Potential Solution:
a. Look for the pair "Error in" and "Dumped"
b. Verify the number of uses of '"'.
c. Insert an extra '"' if needed after the ".." and before the ":", thus
Error in "trellis.settings" + "x + z + abcdefghij ..": Non-numeric
first operand
My discomfort is that we are then modifying the output, not just
highlighting it.
* (BR) Scripts in S-PLUS 4.x provide quite similar functionality to
the ESS front-end, and are worth investigating.
* (Duncan Murdoch, on IDEs):
I don't understand the details of what you're saying, but for an
example of a very good IDE, you should look at Borland Delphi,
version 3. It has some very nice features:
- at any point, you can ask to see a list of legal identifiers to
insert. These are presented in order from most to least local, so
usually the one you want is near the top. The IDE knows enough
about the syntax of the current line to only suggest things that
would be legal there.
- when you type a dot (more or less equivalent to $ in S), you're
presented with a list of fields and methods for the object or record
you're working with.
- you can point at any identifier and hit a key for the help for that
identifier. Because it's an object oriented system, there are often
multiple different methods with the same name; the IDE picks the
appropriate one by the context.
Other unrelated things that Delphi does nicely which Splus would do
well to emulate:
- you can ask for a new object of a specific type, and it will insert
appropriate skeleton code for it.
- the object browser is quick and convenient to use! Of course, the
objects in Delphi tend to be quite different from the objects in
S...
- it has lots of nice visual design tools for writing user interface
code.
* Bob_Dorazio@usgs.gov (Bob Dorazio) on IDEs:
I have no experience with emacs, but in response to your question
take a look at Watcom's IDE for C++. This IDE is the best I have
ever seen! The source code editor is fantastic and the level of
integration between the source code editor, the compiler, the
debugger, and the utility for "building" executables or libraries
surpasses that of any other IDE I have used.

I think Tony spotted the source of the problem. I think I did it.
The goal in ess-iw32.el was to change the behavior of
ess-eval-linewise and ess-eval-region to call the Windows S-Plus GUI
through the DDE protocol. This was successful. I and others have used it daily
for the past 6 years.
I intended to restrict the change to the S-Plus
GUI. My thinking at the moment is that I didn't do that restriction well enough.
I get an emacs freeze in both R and Sqpe on Windows. An initial look at emacs
variables makes me think that the "if" tests in ess-iw32.el for the substitute
definitions of
ess-eval-region
ess-eval-linewise
ess-load-file
ess-dump-object-into-edit-buffer
ess-display-help-on-object
ess-dump-object
aren't precise enough to detect that R and Sqpe should not be sent to ddeclient.
This note goes on the master "To DO" list. Do we have one?
Taking it off the list is not a high priority for me because the work around of
C-g is so easy.
