If I understand Ethan, he thinks arrows should be shortened even more than I do. But I still disagree. Basic user interface issue: set arrow from ptA to ptB will be expected to do precisely that: start at ptA and end at ptB. *If* this is the provided behavior, the user can always adjust these points appropriately to achieve the effects Ethan mentions in 2). Basic issue of cooperation: let the user apply arrows however they desire. Just make it easy to do so. (E.g., let the user decide if an arrow is an appropriate visual aid for his/her purpose.) Example: 'plot with vectors' will be badly screwed up if the vectors do not start and stop exactly where they should. Basic implementation issue: there should be no ambiguity about what "from" and "to" mean. Additionally, for filled arrows (and on capable terminals *all* heads can be drawn as filled) this keeps the drawing computations as simple a possible. (Related to this: an arrow without a head should start and stop and the same precise location as an arrow with a head!) Finally, on the interpretation of where an arrow goes, I am not proposing an idiosyncratic interpretation. To the contrary, I believe it is very standard. (Compare e.g. the LaTeX picture environment.) And contrary to Ethan's claim, I argue that this provide a good match for how lines are handled. Lines are generally expected *not* to project beyond the path endpoint. Using PostScript terminology, the natural presumption is a butt cap, and this is the natural default. Ethan seems to be suggesting that choosing a projecting square cap should be the default. I cannot recognize this as a standard practice. But after all is said and done, they key issue is: what will users expect, and what makes it easiest for them to achieve precisely what they desire in a predictable fashion? I was personally startled to find that arrows project past their assigned end point, so my view is obviously that this is unexpected and undesirable behavior. What is more, with this behavior it is essentially impossible for me to make an arrow terminate precisely where I wish it to. This too is very undesirable. Finally, with the new flexibility for arrowheads, the termination of the arrowhead will become even harder for a user to anticipate since it will change with the angle used for the arrowhead. If there were implementation issues that spoke against this, I would understand some hesitancy. But implementation is actually simplified for filled heads. (And *all* heads can be filled on capable terminals.) For nofilled heads it is basically a matter of computing the mitre to offset the head and the shaft length. Cheers, Alan Isaac |

The CVS source tree has an error in ./prepare that wasn't there a week or two ago. -------- configure.in: 7: required file `./config.hin' not found FATAL ERROR: Autoconf version 2.52 or higher is required for this script Some part of the preparation process failed. Please refer to INSTALL for details. -------- In looking back at a version from a couple weeks ago that worked, I see that there is no file called "config.h.in", just a "config.hin".

[apologies if you receive this message twice. Since I'm not entirely
sure that the new gnu...@li... is working,
I have CCed various interested parties directly]
Petr Mikulik and John Bollinger alerted me to the recurrence of an
old problem. When (1) gnuplot is run from a script and (2) mouse
input is enabled, then characters are dropped from the input=20
stream.
I initially thought this was something I had broken with my X11
initialization patches (revisions 1.71 - 1.74 of term/x11.trm).
But after backing these out altogether, I still see the problem,
although possibly with a lower frequency.
After much poking about in the source code, I came
across this bit in term/x11.trm
/* apparently multi-character inputs like escape sequences
* but also mouse-pasted text got buffered and therefore
* didn't trigger the select() function in X11_waitforinput()=
=2E
* Switching to unbuffered input solved this (although I don'=
t
* really like this solution 23 Jan 2002 (joze) */
setvbuf(stdin, (char *) 0, _IONBF, 0);
Commenting out this one setvbuf() line solves 99% of the=20
problem in my tests using the awk script below. =20
With the setvbuf() in place, running the awk script causes the
first 120+ plot commands to be lost in transit!!!!!!
Without the setvbuf() command, only a single character is
dropped - the first one following the first plot command.
Before proceeding any further, I'd like to hear more detail from=20
Johannes about what problem this line was originally fixing.
I have not noticed any dropped paste events or mouse clicks,
but I may not be testing the right combination of events.
It would also be good to hear from Petr or some other Octave
user as to whether removing the setvbuf() line also fixes
things in Octave.=20
My test awk script:
BEGIN {
gp=3D"./gnuplot"
print "set term post" |gp
print "set mouse" |gp
print "set term x11" |gp
for (k=3D1; k<500; k++) {
print "reset"|gp
print "plot x*x*" k |gp
}
}

Given that, I'm all for integrating this patch ASAP. > Do you do such a diff-save in a similar way? Yes. I salvaged a script similar to yours ages ago, from a mail to info-gnuplot IIRC. It's called 'reduce-gnuplot-output', it's a csh script (of all things), and it only works for named files. A better approach to the whole task would almost certainly be to integrate it into gnuplot itself. But for that to become feasible, we'ld need a massive refactoring of the whole internal status stuff: *) organize the set/show/save/unset/reset implementations by variable, not by command, i.e. the set, show, save, unset and reset (default status) for a given setting should all be in *one* place, not scattered over 4 files (set.c,show.c,unset.c,misc.c). This would make things a lot more OO-ish. *) Add a new method, or a flag to the 'save-variable' method of each setting, so it saves only the state different from the default. *) Add an option to 'save', or a new command 'savediffs' to call that new method. This would be a ton of work, unfortunately. I.e. I'd advise to delay this until after the 4.0 release we all still agree should happen soon --- right? -- Hans-Bernhard Broeker (br...@ph...)

I wanted to let the "save" command to save to file only differences wrt "reset" status of gnuplot, so I've patched save_command() + surrounding routines to allow write to pipe. In the attached file, there is that patch + my favourite script "gpsavediff". Do you do such a diff-save in a similar way? Or do you have a similar script with a different functionality? Unless there are negative responses, the patch will go to cvs. But what to do with gpsavediff? Maybe some web page... --- Petr Mikulik |

I am pretty sure that SF is protecting email addresses pretty well, even in archives. They have even stepped up anti-spam recently, which makes a considerable difference (for a while, I was getting most of all spam through SF). Can we please stop this thread now? Thank you. |

I get about 400 spams per day (last time I checked) and SA catches all but 2 or 3. And alot of the 2-3 that get through are because my email is at the front of the alphabet. When I used to report missed spams the result was always 'known spam'. By the time I reported it it had become 'known' due to the reports of others :-) Andy (who will be named Zachary in the next life) |

I do not like this!!! Not one bit. With the amount of spam that was being routed through Dartmouth, it is clear that this facility is/was a spammer target. It is not a far stretch of the imagination that an automated program would target and query such a list to collect email addresses. Please, people's addresses cannot be placed on a list that is publicly available. And the sooner the Majordomo list goes down, the better, as far as I'm concerned. I've just been discussing the sudden occurrence of spam with multi- recipients of certain IEEE alias addressed emails, and I'm not the only who would find something like the Majordomo "who" disconcerting. Please see if the SF email list can be made private, accessible only to those four of you knowing the password. Once a person's address gets out and starts floating about the spammer lists, I suspect the game is over. Thanks, Dan |

Me? :) Dave is the one who doesn't seem to mind them... Anyway, my original point is that Dartmouth list seemed to be a real spam target. There seemed to be about one or two per day routed through it. I just imagine there was a ton of spam we didn't see. I suspect there are spammers out there that collect emails by an automated means. (Would this be technically a form of data mining?) I suspect that collecting addresses and selling them is a source of revenue for some. (Should be made universally illegal folks, I decree.) Call me paranoid, but I'd prefer not having my address on a list in which an automated program can "who" it and search for @ symbols. I can't recall a single spam to my alias address for about three years until recently. (I'm not blaming gnuplot-info.) And now I can see the slow increase in amount. (Expletive deleted.)

I assume you were saying they shouldn't be public, rather than that they should ..? I guess the lists were configured in the days before spam was so bad, and no-one ever changed them. It is mildly useful for people to be able to find out the exact address they are subscribed as, but that's not a strong argument. OTOH I pretty much accept that my email address is going to get into various lists no matter what I do, so I have to have a decent anti-spam mechanism. So I don't care who gets hold of my address.

At least using the Postscript Terminal with rounded line joints, I really would prefer to preserve the stroked path around the arrow heads even when they are filled. If you eliminate the stroked path the corners of the arrow heads would be sharp what does not fit to the round line joints and line ends. I just think of a plot generated with the "round" option to be painted using a round pen as done in engineering drawings. To fit the DIN norm for drawing arrow heads (filled, 15=B0, length 5 times line width), I have programmed the filled arrow heads. And these should preserve round corners, I think. Fur butt line joints, we could think about eliminating the stroked path. But this leads to a problem of different size of arrow heads for butt and rounded line ends.

I did receive my own post. Go figure.

All users have "not metoo" unset. Sounds like a bug. I'll see if I can raise any attention at sourceforge. Can I hear me now? --ckg On Thu, Oct 16, 2003 at 06:05:40PM -0400, asad wrote: > I did receive your following post. > > -----Original Message----- > From: gnu...@li... > [mailto:gnu...@li...] On Behalf Of Lars Hecking > Sent: Thursday, October 16, 2003 10:09 AM > To: gnu...@li... > Subject: Re: list migration > > > [OT] > > I am not receiving any copies of my own list posts.
