11.85; differences of preview in Emacs.app 23.0.60

Peter Dyballa — 2008-12-03T11:32:54

Hello! When I try to create previews from the enumeration in the first section of preview/circ.tex I succeed only when the LaTeX buffer is in DVI mode, but I fail when in PDF mode. This happens with the Cocoa/ GNUSTEP variant Emacs.app on Mac OS X 10.4.11 (Tiger) with an unmodified TeX Live 2008 distribution. There is (mostly, i.e., it sometimes fails, too) *no* difference when I use the X client version from the same code basis, i.e., the previews are created successfully in DVI and in PDF mode. The X client version (until now) always was able to create previews in preview/circ.tex when I had added tracingall to the options when loading preview. Otherwise it could (often) fail. In Emacs.app it always failed. Caching of the preamble was always off, process-connection-type is t. When working continuously at the same time with both Emacsen, preview detected that _region_.tex had changed on disk and re-read that file. The auxiliary (static) dvipng programme is: pete 243 /\ ls -l `w

Re: \em underline goes to edge of buffer instead of edgeof text

This would be an Emacs bug not one of AUCTeX. FWIW, I cannot reproduce this with my versions of Emacs 22 and CVS Emacs on X11.

\em underline goes to edge of buffer instead of edgeof text

Chris Pickett — 2008-11-26T02:52:53

Hi, Using 11.85-3, the following file: one {\em two three} four shows " two" underlined but the underline goes all the way to the edge of the buffer, and then continues on the next line to the end of the word "three". I think it should go only to the end of the word "two" before continuing below. Attached is a screenshot. I also uploaded it here for now in case you're scrubbing images: http://www.sable.mcgill.ca/~cpicke/auctex_em_underline_bug.png Cheers, Chris

Re: TeX fill instead of LaTeX fill for \subsection attop of file

Ralf Angeli — 2008-11-23T20:43:58

Well, basically the detection of the file type by looking at macros is a bottomless pit, but since looking for \subsection and \subsubsection in addition to \section does not impose a big penalty on performance I've added those.

I'm sorry, I thought you meant there should be a Command sub-menu or menu item specific for AUCTeX. I didn't realize everything in Command was AUCTeX specific, or I thought a Command menu existed normally, or I don't even know what I thought. Something illogical, but I guess I rarely use menus. Mea culpa for not reading closely. Looking at the manual and seeing it applies to TeXinfo too which I do edit occasionally, this makes sense for me personally also. Perhaps, getting down to the supposed "bug" here, it would be possible to make \subsection be such a string. After all, if \section is such a string, presumably there's an argument for \subsection being derived from it and inheriting many of its properties/connotations/whatever. (Of course the same would apply to other section headers too.) Ah, I remember these guys from some past life. Now I know what they do! Thanks for your help, Chris

Re: TeX fill instead of LaTeX fill for \subsection attop of file

Ralf Angeli — 2008-11-21T19:51:06

TeX mode and LaTeX mode. Wow, you make me jump through hoops. I had to switch to a Linux console to see what you mean because the GTK port behaves differently. So I guess I can confirm it. But couldn't you just have said "Yes, there is a menu called 'Command'"? You shouldn't have to. It's the default. This was just an example demonstrating that forcing LaTeX mode under every circumstance is not a good idea. Okay, I now actually checked with a file as you provided it (shame on me for not doing so before) and yes, it falls back to Plain TeX mode because there is no string which is recognized by AUCTeX identifying the file as being a LaTeX file. You have two options dealing with the problem: 1) Set `TeX-force-default-mode' to t. This will disable the automatic file type recognition and always use the mode specified in `TeX-default-mode'. However, I don't recommend this because it will disable a useful feature and is usually not necessary because there is option 2. 2) Set the varia

Re: TeX fill instead of LaTeX fill for \subsection attop of file

Chris Pickett — 2008-11-21T18:16:46

Yes, sorry. I'm unfamiliar with formal emacs terms. What are the actual TeX/LaTeX modes called? I don't see a specific AUCTeX menu, but "F10 l" gives me a LaTeX menu if it says "section" instead of "subsection" in the file, and "F10 T" gives me a TeX menu if it says "subsection" as written above. Furthermore, "F10 c l" runs LaTeX and "F10 c t" runs TeX correspondingly. Can you confirm this? Not that I know of. I looked through my .emacs and didn't see anything. How do I set TeX-default-mode to be LaTeX? I've never used ConTeXt, presumably I can start caring if/when. Of course, the archives might benefit from a more general solution if there actually is one. Why do I care about this? I break large documents into several files and \input them from the master document file, and so sometimes I end up having a single subsection in a file. Thanks for your help, Chris

Re: TeX fill instead of LaTeX fill for \subsection attop of file

Ralf Angeli — 2008-11-21T17:39:24

There are no such modes as "TeX Fill mode" and "LaTeX Fill mode". Do you perhaps refer to the modeline indicator? Hard to say without more information. Are you sure AUCTeX is enabled? There should be a Command menu if it is. Not really, at least not with respect to macros used in the document. If AUCTeX cannot derive the mode from the document contents it should fall back to the mode given by `TeX-default-mode'. Perhaps you changed that? Even for ConTeXt files?

TeX fill instead of LaTeX fill for \subsection at topof file

Chris Pickett — 2008-11-21T09:09:34

Hi, If I have: \subsection % comment text in a file and edit it, I end up in TeX Fill mode instead of LaTeX Fill mode. If I hit M-q in the paragraph above, it will reflow the text into the comment like so: \subsection % comment text Is this a bug in AUCTeX? Is there a list of things that will activate TeX mode instead of LaTeX mode? Is there some way to always force LaTeX mode? If it's not an AUCTeX bug, who else can I ask for help? Thanks, Chris

I don't find that right. After all, D. Knuth has written plain TeX and not LaTeX. Plain TeX users are helpless with their problems. I wish I had the skills to fix them myself but unfortunately haven't, but expert people should not in my opinion create facilities only and only for LaTeX, which is a mere sun of plain TeX. I understand that this happens because so many people use LaTeX and so few people use plain TeX, but this reason is not sufficient IMHO. Thanks, bye Rodolfo

Re: Re: Filling paragraphs with double dollar displayedmath

No. I mean that in LaTeX mode there is code which, in principle, could help solve the problem. Because in LaTeX mode $$ is unsupported.

Re: Re: Filling paragraphs with double dollar displayedmath

Ralf Angeli — 2008-11-14T18:20:58

In case of the preceding text it is easy to find the paragraph boundary because there is a line starting with $$. Determination of paragraph starts or separators usually works by looking at the start of a line. In AUCTeX there is also code that looks at the end of a line, but this is only used in LaTeX mode. Plain TeX mode relies on Emacs facilities for filling.

Re: Filling paragraphs with double dollar displayedmath

Rodolfo Medina — 2008-11-13T14:10:59

I'm a plain TeX user, so I must use the double dollar to display equations. The problem only occurs when the displayed equation is two or more lines long, and only for the text succeding the equation, not for the preceding text. So: bla bla bla $$ long equation = over two lines$$ bla bla bla becomes: bla bla bla $$ long equation = over two lines$$ bla bla bla , but: bla bla bla $$ long equation = over two lines$$ bla bla bla becomes: bla bla bla $$ long equation = over two lines$$ bla bla bla . If I use a blank commented line between the equation and text, it works again: bla bla bla $$ long equation = over two lines$$ % bla bla bla becomes: bla bla bla $$ long equation = over two lines$$ % bla bla bla Can this bug be fixed? Thanks Rodolfo

I freshly installed auctex cvs. I'm a plain TeX user and wish that, when filling a paragraph with `M-q', the double dollar would not move, whereas it does actually. Example: bla bla bla $$x = y$$ bla bla Is it maybe a bug? Thanks for any help Rodolfo

Fixed in CVS. Thanks for the report. Besides, please send only plain text messages to this list.

You can work around this by using a different file name, especially one where the base name is not the same as a LaTeX style or class file.
