pdftex process on MAC OSX-- more again

[Robert Betz]

Seemed to have narrowed down the problem of pdftex not stopping upon exit of 
Lyx. I was using the Koma-script 2 letter template, and I added a maths 
\rightarrow symbol in the text of the letter. This problem would then appear. 
Don't know why.  Take it out and the pdftex process stops and starts correctly 
with Lyx.

 Just curious, will pdftk preserve links between chapters? This seems
 rather nontrivial.

Pdftk output is exactly like the original file, so it keeps all links.
All links in the generated file will work if they point to an existent position.
For example, if there is a link for the chapter 10, but the chapter 10
is not in the file, that link will not work (obvious?).

 I have tried to split the document by pdf creator. it works but, the link 
 cannot work.
 Any suggestion?

Use Pdftk. http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
It is much easier than using a pdf printer like PDF Creator, and the
output is much better.

Its usage is trivial:

- pdftk infile.pdf cat 1-20 output outfile.pdf
This command create a new file named outfile.pdf with the pages 1-20
from infile.pdf.

By default, the metadata is lost (bookmarks, authorname, title, password etc).
But you can use pdftk's update_info parameter to insert metadata on
a file. Google it if you need.


Take care,

On-the-fly spellchecker

[Julio Rojas]

Dear all. I have been using Lyx 2.0 (Windows 7) with very much delight.
Nonetheless, there is a nagging problem that is more annoying than damaging.
When the on-the-fly spellchecker signals a mistake, sometimes when you
select the correct spelling, the cursor jumps to another instance of the
mistake in the document. It is difficult to pinpoint the cause, as it is not
frequent or predictable. It only happens every now and then. The document
I'm working with is big and has many spelling mistakes (in Spanish). Have
you seen this problem before?

If you need more info, let me know how can I gather it.

Keep the good work up. Regards.

If it happens for any file, then go back to LyX, create a new file (e.g, 
newfile.tex) with just one line of text, and export it as a LaTeX (pdflatex)

pdflatex newfile. 

If that doesn't work, it's a problem with your TeX installation. You could then

Re: eps graphics fails when displaying in pdf mode if inserted by ERT \includegraphics

 Well, I exported a LaTeX file and the difference was really just the  four 
 letters:

 .eps

 I removed them and, voilá, problem solved!

But only, if you also have a *.pdf version of the same file.

 So I'd like to re-phrase  my original question:

 why isn't the filename extension .eps  allowed?

The 'pdftex' engine in PDF output mode (command `pdflatex`) does not
support EPS graphics. 

The 'pdftex' engine in DVI output mode (command `latex`) does not support
PDF graphics.

If the argument to \includegraphics has no extension, it is added by the
graphics package depending on the output format and available graphic files.

LyX converts graphics to the required format in a pre-processing step -
but not for ERT (using ERT you are on your own, this is a feature).

 How can I solve that problem?

a) do not use ERT for the graphic input command

b) provide both, EPS and PDF versions and leave out the extension in the
   ERT.

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Robert Betz]

Jens, 

It is not happening all the time with the system, but only under a very
specific class file.  Having thought about it a bit more after the
initial posting it may be an issue with pdftex itself, or with the
Python script the invokes it (from Lyx). 

If you create new file using the koma-letter2.lyx template file (which
uses the scrlttr2 latex class. The template is a default one in 1.6
series Lyx) and go it not math mode and insert a symbol in the text
somewhere (I inserted a \rightarrow a symbol). 

Save the file, and exit and reload.  Simply reloading the file will
start pdftex and it will continue to run, even if you exit Lyx again. 

This appears to do this on all machines that I run this on.  Also
happens under 1.6.10.  It may be an issue with pdftex and this use of it
with this class, but nevertheless the Python script that starts pdftex
should stop it on Lyx stopping.   

Incidentally the file compiles and displays OK.

running cygwin or unix script from within lyx

[Venable]

Hi all,

I have written a couple of cygwin scripts to automate some time-consuming
repetitive tasks and would like to be able to run these from within LyX, for
example via a keyboard shortcut or a customized button on a toolbar. Is this
sort of thing possible? If so, does anyone have advice on how to set it up?

As an example, I like to use the pdfpages package to include external pdfs.
However, I often use relative paths (e.g. when collaborating with co-authors
on Dropbox and the like), and as we know LyX cannot handle this because of
all the copying to temporary directories and so on that LyX prefers. So,
I've written a very simple script to export the lyx file to tex and then
compile using miktex. It would be great if I didn't have to fire up CygWin
and type in the command and filename - rather, I'd prefer to designate a
keyboard shortcut or menu option within LyX that would tell cygwin to run
the script and pass it the current filename.

Many thanks in advance for any advice and please let me know if the question
needs clarifying, or if there is a different, better way.

The only real way to do this, so far as I know, is to define a converter 
that will call your script. This converter might, for example, replace 
pdflatex as a LaTeX--PDF converter. There are a number of ways to do 
this, so the best way will depend on the details.

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Jens Nöckel]

Bob,
I'm not sure I understand the problem, but I'm guessing you inserted a 
character like → into the text, while not in math mode. If so, you could try to 
circumvent the problem by going to Document  Settings  Fonts and changing the 
template's Roman font from Palatino to Default.

I don't see the same pdflatex crash as you, but LyX displays a latex error 
message if I try to use Palatino font with that \textrightarrow  character. 
So I can't be sure if this helps you. Could it be that your TeX installation is 
out of date?  

It may be worth thinking about how LyX can keep track of pdflatex processes it 
has spawned, so that it can kill -9 crashed processes when the user exits LyX 
(after warning about it). I don't think that anything like that has been 
implemented at this point. And of course that wouldn't help fix the root cause 
of your problem.

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Robert Betz]

Jens, 

The process that is left running is called pdftex (not pdflatex), and
its parent process is called Python, whose parent process is Lyx.  That
is the sequence of parent to child processes. 

In relation to what I inserted into the koma-let2.lyx template file it
was simply a → inserted in MATH mode, not text mode.  It does not matter
what symbol you insert in Maths mode. 

To reproduce it you simply load up the koma-let2.lyx template, compile
it as an initial test.  It will compile, and if you look at the
processes the pdftex process will have started with the compile, and
then would have closed. So it no longer appears on the list of
processes. 

Now add in in a symbol in Maths mode. Compile the same file but with
only this symbol added.  The pdftex process will continue to run once
the compilation is complete.  Quit lyx, and you will see the pdftex is
still running and consuming 100% of the core that it is running on. 

You have to do a Quit from the Activity Monitor to stop pdftex.  The
Python process )the parent of pdftex) stops when Lyx is exited. 

It would be a good idea in the future to make sure that Lyx closes all
the process that it is responsible for, even if a process has gone
rogue.  Of course an error message is handy if this is occurring. 

Thanks for your comments on this issue.

Re: eps graphics fails when displaying in pdf mode if inserted by ERT \includegraphics

 Well, I exported a LaTeX file and the difference was really just the  four 
 letters:

 .eps

 I removed them and, voilá, problem solved!

But only, if you also have a *.pdf version of the same file.

 So I'd like to re-phrase  my original question:

 why isn't the filename extension .eps  allowed?

The 'pdftex' engine in PDF output mode (command `pdflatex`) does not
support EPS graphics. 

The 'pdftex' engine in DVI output mode (command `latex`) does not support
PDF graphics.

If the argument to \includegraphics has no extension, it is added by the
graphics package depending on the output format and available graphic files.

LyX converts graphics to the required format in a pre-processing step -
but not for ERT (using ERT you are on your own, this is a feature).

 How can I solve that problem?

a) do not use ERT for the graphic input command

b) provide both, EPS and PDF versions and leave out the extension in the
   ERT.

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Robert Betz]

Jens, 

It is not happening all the time with the system, but only under a very
specific class file.  Having thought about it a bit more after the
initial posting it may be an issue with pdftex itself, or with the
Python script the invokes it (from Lyx). 

If you create new file using the koma-letter2.lyx template file (which
uses the scrlttr2 latex class. The template is a default one in 1.6
series Lyx) and go it not math mode and insert a symbol in the text
somewhere (I inserted a \rightarrow a symbol). 

Save the file, and exit and reload.  Simply reloading the file will
start pdftex and it will continue to run, even if you exit Lyx again. 

This appears to do this on all machines that I run this on.  Also
happens under 1.6.10.  It may be an issue with pdftex and this use of it
with this class, but nevertheless the Python script that starts pdftex
should stop it on Lyx stopping.   

Incidentally the file compiles and displays OK.

running cygwin or unix script from within lyx

[Venable]

Hi all,

I have written a couple of cygwin scripts to automate some time-consuming
repetitive tasks and would like to be able to run these from within LyX, for
example via a keyboard shortcut or a customized button on a toolbar. Is this
sort of thing possible? If so, does anyone have advice on how to set it up?

As an example, I like to use the pdfpages package to include external pdfs.
However, I often use relative paths (e.g. when collaborating with co-authors
on Dropbox and the like), and as we know LyX cannot handle this because of
all the copying to temporary directories and so on that LyX prefers. So,
I've written a very simple script to export the lyx file to tex and then
compile using miktex. It would be great if I didn't have to fire up CygWin
and type in the command and filename - rather, I'd prefer to designate a
keyboard shortcut or menu option within LyX that would tell cygwin to run
the script and pass it the current filename.

Many thanks in advance for any advice and please let me know if the question
needs clarifying, or if there is a different, better way.

The only real way to do this, so far as I know, is to define a converter 
that will call your script. This converter might, for example, replace 
pdflatex as a LaTeX--PDF converter. There are a number of ways to do 
this, so the best way will depend on the details.

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Jens Nöckel]

Bob,
I'm not sure I understand the problem, but I'm guessing you inserted a 
character like → into the text, while not in math mode. If so, you could try to 
circumvent the problem by going to Document  Settings  Fonts and changing the 
template's Roman font from Palatino to Default.

I don't see the same pdflatex crash as you, but LyX displays a latex error 
message if I try to use Palatino font with that \textrightarrow  character. 
So I can't be sure if this helps you. Could it be that your TeX installation is 
out of date?  

It may be worth thinking about how LyX can keep track of pdflatex processes it 
has spawned, so that it can kill -9 crashed processes when the user exits LyX 
(after warning about it). I don't think that anything like that has been 
implemented at this point. And of course that wouldn't help fix the root cause 
of your problem.

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Robert Betz]

Jens, 

The process that is left running is called pdftex (not pdflatex), and
its parent process is called Python, whose parent process is Lyx.  That
is the sequence of parent to child processes. 

In relation to what I inserted into the koma-let2.lyx template file it
was simply a → inserted in MATH mode, not text mode.  It does not matter
what symbol you insert in Maths mode. 

To reproduce it you simply load up the koma-let2.lyx template, compile
it as an initial test.  It will compile, and if you look at the
processes the pdftex process will have started with the compile, and
then would have closed. So it no longer appears on the list of
processes. 

Now add in in a symbol in Maths mode. Compile the same file but with
only this symbol added.  The pdftex process will continue to run once
the compilation is complete.  Quit lyx, and you will see the pdftex is
still running and consuming 100% of the core that it is running on. 

You have to do a Quit from the Activity Monitor to stop pdftex.  The
Python process )the parent of pdftex) stops when Lyx is exited. 

It would be a good idea in the future to make sure that Lyx closes all
the process that it is responsible for, even if a process has gone
rogue.  Of course an error message is handy if this is occurring. 

Thanks for your comments on this issue.

Seemed to have narrowed down the problem of pdftex not stopping upon exit of

Don't know why.  Take it out and the pdftex process stops and starts correctly

Pdftk output is exactly like the original file, so it keeps all links.
All links in the generated file will work if they point to an existent position.
For example, if there is a link for the chapter 10, but the chapter 10
is not in the file, that link will not work (obvious?).

Use Pdftk. http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
It is much easier than using a pdf printer like PDF Creator, and the
output is much better.

Its usage is trivial:

- pdftk infile.pdf cat 1-20 output outfile.pdf
This command create a new file named outfile.pdf with the pages 1-20
from infile.pdf.

By default, the metadata is lost (bookmarks, authorname, title, password etc).
But you can use pdftk's "update_info" parameter to insert metadata on
a file. Google it if you need.


Take care,

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Robert Betz]

Jens, 

It is not happening all the time with the system, but only under a very
specific class file.  Having thought about it a bit more after the
initial posting it may be an issue with pdftex itself, or with the
Python script the invokes it (from Lyx). 

If you create new file using the koma-letter2.lyx template file (which
uses the scrlttr2 latex class. The template is a default one in 1.6
series Lyx) and go it not math mode and insert a symbol in the text
somewhere (I inserted a \rightarrow a symbol). 

Save the file, and exit and reload.  Simply reloading the file will
start pdftex and it will continue to run, even if you exit Lyx again. 

This appears to do this on all machines that I run this on.  Also
happens under 1.6.10.  It may be an issue with pdftex and this use of it
with this class, but nevertheless the Python script that starts pdftex
should stop it on Lyx stopping.   

Incidentally the file compiles and displays OK.

(pdflatex) file. Then try to pdflatex that exported file from the
_terminal_ with "pdflatex newfile".  



If that doesn't work, it's a problem with your TeX installation. You
could then send the tex file and the latex log. You could also try
paring the file down by deleting any "\usepackage" commands in it, until
the error goes away. Maybe you have some package or font installed that
causes this crash. This could be hard to find if you have local
installations that differ from the standard distribution.

running cygwin or unix script from within lyx

[Venable]

Hi all,

I have written a couple of cygwin scripts to automate some time-consuming
repetitive tasks and would like to be able to run these from within LyX, for
example via a keyboard shortcut or a customized button on a toolbar. Is this
sort of thing possible? If so, does anyone have advice on how to set it up?

As an example, I like to use the pdfpages package to include external pdfs.
However, I often use relative paths (e.g. when collaborating with co-authors
on Dropbox and the like), and as we know LyX cannot handle this because of
all the copying to temporary directories and so on that LyX prefers. So,
I've written a very simple script to export the lyx file to tex and then
compile using miktex. It would be great if I didn't have to fire up CygWin
and type in the command and filename - rather, I'd prefer to designate a
keyboard shortcut or menu option within LyX that would tell cygwin to run
the script and pass it the current filename.

Many thanks in advance for any advice and please let me know if the question
needs clarifying, or if there is a different, better way.

The only real way to do this, so far as I know, is to define a converter 
that will call your script. This converter might, for example, replace 
pdflatex as a LaTeX-->PDF converter. There are a number of ways to do 
this, so the best way will depend on the details.

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Jens Nöckel]

Bob,
I'm not sure I understand the problem, but I'm guessing you inserted a 
character like → into the text, while not in math mode. If so, you could try to 
circumvent the problem by going to Document > Settings > Fonts and changing the 
template's Roman font from "Palatino" to "Default".

I don't see the same pdflatex crash as you, but LyX displays a latex error 
message if I try to use Palatino font with that "\textrightarrow"  character. 
So I can't be sure if this helps you. Could it be that your TeX installation is 
out of date?  

It may be worth thinking about how LyX can keep track of pdflatex processes it 
has spawned, so that it can "kill -9" crashed processes when the user exits LyX 
(after warning about it). I don't think that anything like that has been 
implemented at this point. And of course that wouldn't help fix the root cause 
of your problem.

Re: pdftex process on MAC OSX Lyx 2.0.0 - more

[Robert Betz]

Jens, 

The process that is left running is called pdftex (not pdflatex), and
its parent process is called Python, whose parent process is Lyx.  That
is the sequence of parent to child processes. 

In relation to what I inserted into the koma-let2.lyx template file it
was simply a → inserted in MATH mode, not text mode.  It does not matter
what symbol you insert in Maths mode. 

To reproduce it you simply load up the koma-let2.lyx template, compile
it as an initial test.  It will compile, and if you look at the
processes the pdftex process will have started with the compile, and
then would have closed. So it no longer appears on the list of
processes. 

Now add in in a symbol in Maths mode. Compile the same file but with
only this symbol added.  The pdftex process will continue to run once
the compilation is complete.  Quit lyx, and you will see the pdftex is
still running and consuming 100% of the core that it is running on. 

You have to do a "Qui"t from the Activity Monitor to stop pdftex.  The
Python process )the parent of pdftex) stops when Lyx is exited. 

It would be a good idea in the future to make sure that Lyx closes all
the process that it is responsible for, even if a process has gone
rogue.  Of course an error message is handy if this is occurring. 

Thanks for your comments on this issue.

It is not happening all the time with the system, but only under a very
specific class file.  Having thought about it a bit more after the

If you create new file using the koma-letter2.lyx template file (which
uses the scrlttr2 latex class. The template is a default one in 1.6
series Lyx) and go it not math mode and insert a symbol in the text
somewhere (I inserted a \rightarrow a symbol). 



Save the file, and exit and reload.  Simply reloading the file will
start pdftex and it will continue to run, even if you exit Lyx again. 



This appears to do this on all machines that I run this on.  Also
happens under 1.6.10.  It may be an issue with pdftex and this use of it
with this class, but nevertheless the Python script that starts pdftex
should stop it on Lyx stopping.   



Incidentally the file compiles and displays OK.

All doing the same thing (pdftex not closing and using 100% CPU), so it
may be my system.  Doing on two though. The parent process for pdftex is
Python, whose parent in turn is Lyx. When Lyx closes down, Python closes
but pdftex is not closing.  Maybe there is some problem with my
installation of Python. It
