However, a prominent warning in the User Guide (6.9.1 ERT Boxes) might
help a bit. Something like:

  Attention: as the text after the ERT box continues on the same line (to
  enable the abovementioned constructs), a comment sign (%) in the ERT
  boc will render not only the remainder of the box but also the rest of the
  non-red line invisible.
  
  Insert a line-break inside the box to prevent this. The collapsed box
  will still be diplayed in-line.

Note that \not is supposed to negate math relations, so I think
that you can get what you want by using

$a\not\mathrel Rb$

Also note that you will get automatic spacing around your new math
relation. If you don't like that, then use

$a{\not\mathrel R}b$

You can add the path to Tools -> Preferences... -> Paths -> PATH Prefix,

Negation: LyX or LaTeX?

[Ernesto Posse]

Hello. I have an issue with the use of \not in math mode, but I am not
sure if the poblem is with LyX or LaTeX itself.

When I try to write "aRb" with the R negated, the diagonal which is
supposed to go over the R does not appear in the right place. I've
tried each of the following, both in ERT and using LyX's math
interface:

$a\not Rb$  result: big space between a and R, / just a little over R.
$a\not R b$ result: same
$a\not{R}b$ result: same
$a{\not R}b$result: smaller space between a and R, but / still not
completely over R.
$a{\not{R}}b$   result: same

It seems that the only way to make it look right is with negative
spaces, but that seems like an ugly hack. Is there any way to negate
the "right" way?

Re: bug?: comment in last line of ERT --> next line of normal text is lost

[Tobias Krause]

Thanks for your answers!
Now I see see there are good reasons for no line break after an ERT and 
it's not a bug.


My guess, though, is that insertion of comments in in-line ERTs is 
pretty rare.  Yours was the first post I've seen concerning it, and 
I've been on the list since around LyX 1.3.5.


One other reason might be that sometimes people just don't realize that 
some words are lost... I myself had the problem once and did not 
realized it until the document was printed and bound... And even then I 
did not know why the text was lost.
Just yesterday I stumbled upon the some problem again - and without the 
source view of 1.5 I guess again I would not have found the reason.


But I guess you are right: there are tons of reasons why this behavior 
is still better than others - and visual indications would be a nice 
thing but are tricky aswell.

Hi All,

I have a problem where a longtable row sometimes enters the footer

the document is generated from a database, i.e. I have to fix the

More of a latex problem I think - try a latex forum.

Thanks for the tip, will have a look into it.


What does this longtable contain? Text only is really supposed
to work - or is there complicated stuff like minipages
or graphics in the cells?
The longtable contains "complicated" stuff like minipages.  Will try 
to remove these and see what happens.


Also, a wrong lower margin setting could cause this.
Maybe the margin doesn't leave enough room for the footer,
or the footer contains some big stuff? Try bigger margins.
The document is a "Test Procedure".  A requirement is that any page 
that can be "filled in" must have a place for the Tester and the 
Witness to sign.  I have placed such a "signature block" in the footer 
of the applicable sections.  It is quite large of course.  It also 
means that the document contains one footer for the start of the 
document and another for the "tests" section.  I have adjusted the 
footer size by using "\advance \textheight by -6\baselineskip" in ERT 
just before the "test" section starts.  Is there a better way of doing 
it?  I am using the geometry package to manage the margins.


I see.
The usual footer is about one line high, so it can contain a page
number and perhaps a few words like a section title or book name.
Latex lets you use a bigger footer
if you like, but then _all_ pages have this tall footer and the space
is never used for ordinary text at all.

I have no experience in varying the text area height, so I can't help
you with that. The problem with doing that is that one never
knows where the page breaks will go, and so the page break might
fall between the size change command and the big block.  Then
you get a problem - space for the big block is reserved on another page
and the block crashes into the text _if_ the page is nearly full.

Two solutions:
1. Make the footer big enough on all pages.
   Useful if most pages needs a signature block, other pages
   will waste paper.

2. Use a small footer, and put the signature block in the normal
   text instead. If you want to push the block down to the bottom,
   put vertical space of the "fill" variety in front of the block. It
   will then go to the bottom of the page even if there is only one
   line at the top.
   If the page is too full, then your signature block will go
   to the next page instead with this solution. This is a good
   solution if a single signature at the end of a multi-page
   section is ok.

Is this a problem? LyX comes with lots of nice document
classes already. And it is the school who decides
what an exercise should look like. If they can say "use LyX",
then they can also say that  "article" is the
standard layout for an  exercise.  Easy enough if they
don't want to make layouts of their own.



Judging by my experience writing books with book and memoir derivatives, and 
from dabbling with koma, no document class is complete enough to do all the 
things you see in the average book in the bookstore. In my case I needed to 
create environments to make tip boxes and warning boxes and other breakouts. 
I also needed to create a "story" environment in every book (I like to have 
stories in italics and indented right and left). I found the document class's 
native lists to be vertically spaced too deeply, making it more probable than 
necessary that the list would cross page boundaries.
  

You are right, the existing classes is not sufficient to write every
book in the stores. (I don't think any other word processor is
up to this task either, for that matter. The popular ones even
struggle with justified text. . .)
But a student usually don't need every formatting feature
found in a bookstore. I have had students using LyX or
latex for making 50-page reports, they had no problems with this.

The style of schoolwork usually comes second to the work itself,
the most important is that the style is consistent and don't
have lots of irritating misfeatures like headings at the
page bottom and such. LyX handles this.

Those that deal in advanced math like the ability to actually write
the math at all - and have it come out good-looking too.
Unless the school's document class, packages and modifying layout file give 
the student EVERYTHING the student needs to format it properly, the student 
will be frustrated.


Anyone who has used WordPerfect or MS Word is very used to creating their own 
styles (paragraph and character), and would be frustrated at the difficulty 
doing that in LyX, unless they're given a document class with supporting 
packages and layout file that does everything they need to do for the 
assignment.
  

My point is, most students don't need that much for an assignment.
Most students who experiment with layout just mess up anyway.
Authors who actually publish & sell their stuff is very different, of 
course.

I mean nest an environment inside a completely different one. Can you do that 
with Increase Depth?
  

Look at the user guide - there is an example of
bullet list, enumerate list and other lists nested inside
each other in a 6-level monster example. Try reading the
entire guide some time, just looking for cool stuff. :-)

You can also nest standard paragraphs inside lists, which is
what you have to do in order to make a multi-paragraph bullet item.

Lots of other things nest too. You can have bullet list inside
lyx-code, or a section heading inside a list. The latter looks silly though.

To nest one paragraph type inside another, first start a new
paragraph and increase depth. Then change to the desired
paragraph types.

The inner paragraph can be almost anything. The outer
paragraph is more limited, not all can have an interior
paragraph as it doesn't make much sense.  A couple of
bullets and some std. paragraphs in a long-winded
enum item is ok though.

Re: bug?: comment in last line of ERT --> next line of normal text is lost

Tobias Krause wrote:

Hi Paul,


  some text [[%comment ]] more text

where [[]] is an ERT box, then "more text" will look to LaTeX like 
part of the comment, because LyX will (properly) not insert a line 
break after the ERT box.  This would IMHO be proper behavior. 

Sounds like proper behavior, but there are some remarks:

  1. This is totally uncontrollable for the user: if "more text" is a
 long text, the user does not know where LyX will break the line -
 and so it's not possible to know which text will be show up in the
 output. From this point of view there would be no advantage of
 this behavior, is there any reason for not inserting a line break
 after ERTs?

There is plenty of reason. ERT can be used in cases where the
latex command inside ERT acts on the following text.
For example, a command that makes higlights the next
character in some way, such as those big characters that
start chapters in some books. Getting an extra newline wouldn't
work in that case.

Or:
ERT \texcommand{  ERT}
The texcommand used might be one that can't handle newlines.


As for user control - the user can put a linebreak after his
ERT comment and avoid this issue. No problem once you know.
Using ERT is an expert option.


  2. Even though this behavior is proper it is risky for the user,
 because there is no visual indication for a behavior which might
 not be obvious or which is just triggered without knowing. Maybe
 it'd be possible to gray out the text which will be gone or to do
 something else to show what will happen...

ERT is there for using latex features that LyX doesn't already
support directly, so LyX has no hope of understanding what's
inside an ERT box. If you want a comment LyX understands,
insert a note behind the ERT box.

Now the % comment seems simple enough but this is not so,
it is possible to write latex commands redefining % to
do something else instead of "comment to the end of the line".
This sort of thing is why LyX just leaves user-defined latex alone.

RE: Problem with Spellcheck

 Hmmm...just a follow-up on this issue. I've had the same problem on

however, I was able to get Lyx to spellcheck fine with no problems. I
can't recall the OS, but I don't think it's service pack 2 of XP

does the spellchecker stop working.

Subject: Problem with Spellcheck

I'm just starting to use Lyx and am running into a problem with the
spellchecker (aspell). I've tried to get it to work with versions 1.4.1,
1.4.5.1, and 1.5.2, all full-bundled installs. All give the same
problem. This is for a windows XP machine. 

When the initial file (splash.lyx) pops up, I can click on Tools->
Spellchecker and the spellcheck seems to run fine. It finds a
misspelling (DVI) right off. If I create a new document, then try to run
spellchecker, the spellcheck page pops up for a second, then disappears.
If I try to run spellchecker again, no window pops up. I've even tried
copying the splash.lyx text to a new document and trying to get
spellchecker to work, but the spellchecker gives the same problem. It
seems only to occur with new documents, since I can still run
spellchecker on splash.lyx.

Is this a bug, or am I doing something wrong?

Thank you,
