Using Lyx with Noweb help offered

[Sam Liddicott]

I've had a dreadful job getting noweb 2.11b and Lyx 2.6.2 to work
together nicely. My pain does make me if anyone uses Lyx with noweb
recently.

I now have a Lyx 2.6.2 document which talks about how to get it working,
requiring various changes to Lyx's noweave filters, and some awk to
fixup the output of notangle.

Of course this entire document is a Noweb article.

It also contains a way of bootstrapping a makefile out of the Lyx
document, and by treating the Lyx document as a sort of read-only source
archive it automatically keeping the extracted sources up to date so
that you can use Lyx and noweb as part of a regular automake/autoconf
project.

I have this document as the final part to two of my Lyx-noweb projects.

I hope that it will be useful to readers, and I invite comment.

Is it appropriate to post this to this mailing list?

[I will of course attach the notangle fixup as well - it would be hard
to extract the notangle fixup tool without already having the fixup tool]

I've made a page at http://wiki.lyx.org/Tools/Noweb but I can't upload
the files because I don't have a password or username to login and can't
find out how to register.

I've attached the two files, please could someone upload them.

  Thanks.

In the mean-time I note that this line:

notangle -filter "/bin/sed '/^...@nl/d;/@text end_/d;/@text begin_inset
Newline newline/s/^.*/@nl/;s/^...@text \\\\backslash/@text /'"
LYXFILENAME.lyx 

(which works at a different document phase with notangle) is better than the
notanglefix I posted.

I'll sort this all out on the wiki on Monday.

What does lyx munge about the file format to the convertors?

[Sam Liddicott]

(I'm using Lyx 1.6.2)
A lyx file of mine has this text (when I look inside the raw lyx file)
*
--8<---**--8<---**--8<---**--8<---**--8<---*
*\begin_layout Section
The ntvfs model
\end_layout

\begin_layout Standard
Many vfs modules may be defined, as types of share backends.

\end_layout

\begin_layout Standard
Each vfs module could be considered to subclass an abstract [[struct
ntvfs_modul
e_context]], and each vfs module should define a struct to define
per-connection
 instance data.
\end_layout*
*--8<---**--8<---**--8<---**--8<---**--8<---*

Apart from the puzzlement of why Lyx breaks the line in the middle of a
word, it all looks fine.

But this is NOT what is fed to the first stage of the Noweb->Lyx noweave
convertor.

If I prefix my convertor with:
cat $$i | tee /tmp/pre
and look inside /tmp/pre, I see this instead:


*--8<---**--8<---**--8<---**--8<---**--8<---
**\section{The ntvfs model}

Many vfs modules may be defined, as types of share backends.

Each vfs module could be considered to subclass an abstract {[}{[}struct
ntvfs\_module\_context{]}{]}, and each vfs module should define a struct
to define per-connection instance data.
**--8<---**--8<---**--8<---**--8<---**--8<---*



Whats going on? Apart from the annoying and bogus quoting of the [ ] and
_ which I'm trying to fix-up, it means that noweave when run from Lyx
will give different answers to noweave when run from the command line -
say a Makefile which tries to generate the pdf.

Portable tex export

[Sam Liddicott]

Is there a portable way to get Lyx to export the latex document in batch
mode, independent of what converters the user happens to have defined?

Such as might be used by a makefile running in an known environment?

(I'm not too pleased about having lyx as a build dependency, but it can
be used in the "make dist" target).

server-goto-file-row goes to line 1

If I type: server-goto-file-row THISFILENAME.lyx 20

Am I using the command wrongly or are there other known problems that
someone can comment on?

Probably. I suspect you haven't run LaTeX on the file yet.

Here's what the docs say:

LFUN_SERVER_GOTO_FILE_ROW

* Action Sets the cursor position based on the row number of generated 
TeX file.


gah! thats horrific!

I mean it's excellent that it can do the reverse mapping of a tex file

but it means there is no way to navigate the Lyx file - even if the 
specified filename ended in .lyx and not .tex


My C sources aren't generated via the tex files (partly because it's not 
simple to get Lyx to export a tex file from a noweb document without 
running noweb).



I really need to be able to navigate to a line (and column even) in the 
Lyx file.

As saved on disk, as this is what gcc is complaining about (I've been
using notangle directly on the lyx file).

atm this isn't working as you say either (for me)...

I fired up a fresh invocation of Lyx, CTRL+N and typed:
now is the time
for all good men
to drink lemonade
at the party

CTRL+S to save as /tmp/file.lyx

I then did a dvi preview, In /tmp/lyx_tmpdir.J19856/lyx_tmpbuf0 I can
see the files that were generated. file.tex shows:

--8<-8<-8<---
\batchmode
\makeatletter
\def\in...@path{{/tmp//}}
\makeatother
\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}

\usepackage{babel}

\begin{document}
now is the time

for all good men

to drink lemonade

at the party
\end{document}
--8<-8<-8<---

and in the command buffer I type (to jump to "for all good men"):

server-goto-file-row /tmp/file.lyx 14

but the cursor just goes back to line 1 again...

I even tried (for good luck):
server-goto-file-row /tmp/lyx_tmpdir.J19856/lyx_tmpbuf0/file.tex 14

but the cursor jumps to line 1 still.

I've tried lines 1-17 but still it won't do anything apart from jump
back to line 1.


I then switched to "Article (noweb)".

I note that a .nw is created as an intermediate file - is this the file
used for the line number mappings or is it the text file generated by
noweave? This question really concerns me because I am trying to map
from source files back to the lyx document, not from the dvi back to the
lyx document.

lyx-code / scrap bug?

[Sam Liddicott]

Please could someone competent with Lyx 1.6.3 try this; create a
literate (noweb) document and have a scrap immediately follow a lyx-code
section.

In the generated .nw file (in the /tmp/lyx* dir when creating a dvi
preview) the file looks like this:

\}
\end{lyxcode}
\selectlanguage{english}%
\inputencoding{latin9}<>=
{
  NTSTATUS status;


The error being that "<>=" is the start of scrap and
should start on a new line.

I shall try and compile lyx 1.6.3 debs against the ubuntu 1.6.2 .dsc
file soon.

logical markup and noweb articles

I found that it is because noweb.sty also defines a \code

I'll try and combine some variant of:

As far as I can tell, noweb.sty doesn't actually use it's \code and
\edoc commands directly, and as noweb/lyx doesn't either, I just added
this line to my documents Latex preamble:

\renewcommand{\code}[1]{\texttt{#1}}

noweb chunk cross references in lyx

[Sam Liddicott]

I can use an ERT: \nextchunklabel{save-handle}
to define a label for a code chunk, and then refer to this from another
part of the document with ERT: \subpageref{save-handle}

Does/Can lyx support this more natively to avoid the ERT, but allow a
new label type beginning with nw: ?

noweb should be a module not a class

I think noweb should not exist as a class, but as a module; what if I

noweb is really used with \usepackage{noweb} showing that it is not
actually a document class at all. Perhaps it would be better as a module?

Also; if \newenvironment is used in the pre-amble, can the defined
environment be added to the drop-down listbox so it can be applied to
the document?

I am now absolutely certain that noweb should be a module and not a class.

I see however that noweb (literate) file format is important to exist so
that noweave knows when to be called.

This is not enough reason to have noweb as a format though, modules must
also have the capability to be inserted into the output pipeline and
make transformations.

noweave should be called if the noweb module is used.

- almost noweave should always be called if it exists!

However I see that there is no conversion filter from Lyx -> Latex like
there is from noweb -> latex

However when add add a conversion filter from Lyx -> Latex I see that it
is never called; is there a way to make this work?

I would add a convertor which piped through awk to detect if noweb
module was used. If so; it would re-invoke through noweave, or after so
many lines of not finding the noweb module it would become pass-through.

Sam

Re: noweb should be a module not a class

[Sam Liddicott]

Wahey: maybe we can get noweb as a module very simply...

I added this file noweb.module to my .lyx/layouts directory (and
reconfigured Lyx).

--8<-8<-8<-8<-8<-8<-8<-8<-8<---
#\DeclareLyXModule[noweb.sty]{Noweb}
#DescriptionBegin
#Adds \usepackage{noweb} to your document, along with the Scrap style.
#Also fixes the CharStyle:Code to work with noweb, redefining nowebs
#\code command to \nwcode (if you need it).
#DescriptionEnd

Format 11

AddToPreamble
\usepackage{noweb}
% noweb breaks code command
\newcommand{\nwcode}{\code}
\renewcommand{\code}[1]{\texttt{#1}}
EndPreamble

Input literate-scrap.inc
--8<-8<-8<-8<-8<-8<-8<-8<-8<---

And now I can add "Noweb" module to "article (KOMA-Script)" and have the
Scrap style made available.

Because literate-scrap.inc says:
OutputType  literate

I get my .nw conversions for free!

I get the warnings:

Package(s) required: noweb.sty.
WARNING: Some required packages are unavailable!

and

Warning: Package not available

The module literate requires a package that is
not available in your LaTeX installation. LaTeX output
may not be possible.


Which I don't understand as I have /usr/share/texmf/tex/plain/misc/noweb.sty

However LaTeX output is just fine!

If I get this fixed, perhaps we can add noweb as a module?

I guess you look at your Lyx preferences File Handling, Converters.

For "Latex (plain) -> DVI" I guess you could change the converter from
"latex" to "c:\bin\latex-dvi.bat $$i $$o"

and your batch file could be:

@echo off
mkdir draft
latex %1 %2
move %2 draft


Or something along those lines; and do likewise your your other converters

alternate code scrap definition

[Sam Liddicott]

This is a long post, but quite exciting to anyone who uses or wants to
improve literate programming with Lyx.

Along with using a literate module instead of a literate class
(attached), I've got a suggestion for an alternate code scrap definition.

Instead of using LatexType Paragraph with LabelType Static, (which
requires literal <>= and @) I suggest these changes:

LatexType Environment
LatextName CodeScrap
LabelType Manual

It means that the first line which normally contains:
<>=

will be the environment's label, shown in a different colour and we can
do without the << >>= because it will still have semantic meaning with
Lyx as the label.

So far, the Latex would come out like this:

\begin{CodeScrap}
[{scrap-name}]
int x=2;
int y=3;
\end{CodeScrap}

Which is not right, but some sed can turn:
  \begin{CodeScrap}\n[{scrap-name}]
into
  \n<>=
and turn
  \end{CodeScrap}
into
  @

before we pass to notangle or noweave.

Such sed is:

sed -e '/\\begin{xdummy}/{s/^.*//;n;
s/^\[{/<>=/;};/\\end{xdummy}/s/^.*/@\n/'

Further-more, we can use optional non-label text on the same line as the
label to contain a cross-reference definition such as would be used by:
  \nextchunklabel{LABEL-NAME}

This means that to add a cross-reference label to a code chunk you would:
1. select "Scrap" from the drop-down
2. type in the scrap name
3. press space
3a. press space again and type the xref label
4. press ctrl enter and start typeing code.

just miss out step 3a if you don't want a cross-reference label.

This sed will do all of that (makes use of the hold space to detect the
CodeScrap environment):

sed -e '/\\begin{CodeScrap}/{h;s/^.*//};/\\end{CodeScrap}/s/^.*/@\n/;
/^\[{/{
  x;/\\begin{CodeScrap}/{x
  s/^\[{/<>=/
  x}
  x
}'

It converted this Lyx (CodeScrap environment):
--8<-8<-8<-8<-8<---
something() start-of-something
  int something() {
int x=2;
int y=3;
  }

something_else
  #warning I'm bored
--8<-8<-8<-8<-8<---

into this latex

--8<-8<-8<-8<-8<---

\nextchunklabel{start-of-something}
<>=
int something() {
  int x=2;
  int y=3;
}

<>=
#warning I'm bored
@
--8<-8<-8<-8<-8<---

Which is spot on!

I wish that a module file could define the conversion filter. The
attached module file says:

OutputType literate

it would be good if there was also:

OutputFilter: sed -e 

which defines a filter which is used to produce the specified output type.

LyX slow at 1 char per second, 94% cpu

[Sam Liddicott]

I'm editing a 146K Lyx document (with no pictures) and the typing speed
is dreadful.

Characters come out at about 1 character per second with top showing 94%
CPU used by Lyx.

The same instance of Lyx tabbed to a small document is very fast.

Has anyone tips on speeding this up?

- hmm a few hours later and a few lyx restarts and it's speeded up again...

I'll keep an eye on it and report back if I find anything else.

Lyx was occupying the top process line of top at 94%. xorg was using 15%
(dual core).

I think if it was other processes Lyx would not have shown 94%.

But I'll check if it happens again, thanks for the advice.

That's a tiny document.
  

Good :-)

Interestingly, there was a similar symptom way back maybe 6 years ago, where 
someone used an n squared algorithm instead of n log n, or something like 
that, for wordwrapping. The developer found it easily and did one of those 
forehead slaps.


You're not using LyX 1.2 or something like that, are you? What LyX version, 
what operating system, how much RAM on the system?
  


1.6.3 with 3Gig RAM, Ubuntu Jaunty 64 with radeonhd drivers.

In other news I'm finding the literate module much more convenient than

Stall indefinitely is usually because latex/tex is trying to read from
stdin.

If you run lyx from a console window then you can type ctrl-d and finish
the stall.

Emphasis with passthrough

[Sam Liddicott]

If I use a layout with "Passthrough 1" then the Lyx "E" emphasis toolbar

Is this a bug, or is there some way I can specify an inset so that it
also inserts Latex macros into an environment defined with Passthrough 1

It is a bug. Note that the semantics of passthru paragraphs is not well

I'm mostly re-written notangle in awk (to fix a few bugs) and so that it

And I want to use an inset instead of <<...>> for including chunks.

I'm also intending to re-write noweave entirely as latex macros if I can

I'm using the attached .layout file, which generates Latex like this;

\begin{CodeScrap}
\item [{new_chunk() }] 
function new_chunk(chunk_name)

{
 active_chunk = chunk_name;
 chunks[chunk_name, "part", ++chunk[chunk_name, "part"] ] =
chunk_name SUBSEP "chunklet" SUBSEP ++chunks[chunk_name, 
"chunklet"];

}
\end{CodeScrap}

Where the \item declares a chunk name.

I also want a \usechunk{chunk-name} which will be shown in Lyx with a 
static label "use chunk", but I don't know if that can be done as an 
inset...


I also want to be able to pass additional optional arguments to the \item.

So although it is "passthrough" it has the same problems as verbatim 
does which is that it still looks for some Latex, in this case \item and 
\end{CodeScrap}, however I'm not too worried. I'll invent a \literal{} 
if I have to (which would have to be expressed in a CodeScrap as 
\literal{{\literal}} no doubt).

environment feature request

[Sam Liddicott]

Could Lyx please set some environment variables before it calls it's
conversion routines? It would save the need to customize the conversion.

My current literate->program filter sets them for me:

cat $$i | newfangle -Rlyx-build - | env LYX_b=$$b LYX_i=$$i LYX_o=$$o
LYX_p=$$p LYX_r=$$r NOWEB_SOURCE=$$i bash

With a lyx-build fragment containing:

PROJECT_DIR="$LYX_r"
LYX_SRC="$PROJECT_DIR/${LYX_i%.nw}.lyx"
NW_DIR="$LYX_p"
NW_SRC="$NW_DIR/$LYX_i"
cd $PROJECT_DIR || exit 1

so that I can extract files in my lyx document directory.

The "extra flag" originaldir seems to do nothing.

latex macro help...

[Sam Liddicott]

I've got an environment CodeScrap that Lyx treats as a list environment. 
Each list item is a literate programming chunk, and the list item name 
is the chunk name.
I will be using the listings package to format the latex output; so I 
start like this:
(Please don't comment on the needless \startCodeScrap and so forth, it's 
just till I get it working).


\long\def\startCodeScrap{

\def\nfitem{\item}

\def\item##1[##2]{

\begin{lstlisting}[name=##2]

}

}

\newenvironment{CodeScrap}{\startCodeScrap}{

%\end{lstlisting}

\def\item\nfitem}


So I re-define item during a CodeScrap environment, so that it starts a 
lstlisting. That works fine; but of course lstlisting is looking for a 
literal \end{lstlisting} I think and there isn't one... now another 
\item or \end{CodeScrap}will occur instead.



I think my \def\item might need to be \long\def\item and maybe have a 
3rd parameter which ends with \item or \end{CodeScrap} (which will be 
hard enough, probably I'll have to do the third parameter ending on a \ 
and then do tail recursion to pull some more if the next symbol isn't 
\item or \end [won't someone write a yacc for tex?)



But I see that I still need to inject the \end{lstlisting} somewhere. I 
try to fake it by way of experiment:


\long\def\startCodeScrap{

\def\nfitem{\item}

\def\item##1[##2]##3\end{

{\begin{lstlisting}[name=##2]##3}

{\endlstlisting}

HELLO ##3

\end

}

}


But not only does it  not work, it's fetching the tokens not in the same 
mode as listings works, and eating my { } and so forth.I realise then 
that if I am going to fetch


ahead to the next item with ##3 and such that I need to mess about with 
catcodes too...



So before I go too far, any advice for me?


(I also realise that my 2nd \item will have to close the lstlisting of 
the previous item and so on)

newfangle - the new notangle and no more noweave Re: latex macro help...

[Sam Liddicott]

I've managed to avoid blowing up my brain and created a noweb aspect for
the latex listings package, with accompanying lyx module.

As a result I don't need to use noweave, but I get noweave looking
output with the listings generated by the listings package with all it's
pretty printing.

The lyx module (called "newfangle") treats each \lstlisting as a noweb
style chunk, and uses the listing name as the chunk name.

It uses the noweb package macros merely to generate the chunk header and
navigation arrows to the previous and next chunk.

This avoids the need to use noweave for most uses, and removes for me
the need to use the literate lyx file format.

I'm still lacking is noweb markup of <>. I need to get
lstlistings to spot these...

Because Lyx doesn't show the listing name visually while editing it can
be very confusing to remember which listing has which name, so I've
added a Chunk style which sets the listing name. This will be persistent
until the next Chunk or the next explicitly named listing.

I prefix most of my listings with a highly visible chunk header.

The Chunk style pretty much just prefixes "name=" to it's text, and then
calls \lstset, but it does some magic to preserve the chunk name into
the listing.

I also have a newfangle awk script which works like notangle, but nicely
recognizes the latex that listings uses to pick out the code. The awk
script has less bugs that notangle, can manage -L output without
breaking the indents, and manage to suck C code into multi-line macros
without breaking.

I can now do literate programming with much more simplicity than before.

I hope that Lyx will be able to accept this work, and make literate
programming work more naturally.

I've been "are we nearly there yet" for the last 6 weeks, and I think my
answer is "yes" (the 3rd time around).

I'll post the code tomorrow, I need to run, but I didn't want anyone
working on my latex macro question now I solved it.

New literate programming with Lyx

[Sam Liddicott]

I've posted on http://www.lyx.org/trac/attachment/ticket/6137/
my alternative literate programming style with Lyx. I put this together
because literate programming with noweb and Lyx has been absolutely
awful in so many ways - if I wasn't a sed wizard I'd have given up.

I encourage people to try this and to give feedback.

A literate class is no longer used, you can have any document class and
add the "Newfangle Literate Listings" module to your document.

Your document will no longer be the "literate" format, so you add a
build script as a conversion from "Latex" to "Program"

Noweave is not needed, but is (mostly) impemented as Latex macros.

The excellent lstlistings package is used for format the listings; it
has good support for syntax highlighting, line-numbering and so forth.

Because lstlistings is used server-goto-file-row almost works, so
compile errors bring you to the write lstlistings at least - but not the
actual line number,

notangle (which was buggy) is not used to generate the source, instead
an awk script, newfangle, is used, fixing various notangle bugs.

A new style "Chunk" is defined which can be used to easily name your
next lstlisting (otherwise right-clicking and using advanced) is a bit
long winded and you can't see the name you give it once you clicked OK.

Tomorrow I hope to post the chapter that produces a Makefile.inc which
automatically extracts all file sources, and can also glue into another
build system using recursive make (if you are writing literate modules
for an existing project).

Future:
I'm planning to add markup conversions between chunks; so that (for
instance) a shell-script fragment when included into a makefile will
automatically have $ converted to $$, and line endings with a \ for
multi-line shell script. This works nicely with lstlistings language
support.

There's already basic support for including fragments into some comment
contexts:

# <>
will cause each line of frag to being with #

<> \
causes each line of frag to end with \, ideal when C code is being
included into a mutli-line C macro.

Cases environment

[Sam Liddicott]

In a display-equation environment I can't get the cases environment to
work properly, unless I just use the first column.

I get the error:


Misplaced alignment tab character &.

 s &
  s\end{cases}$
I can't figure out why you would want to use a tab mark
here. If you just want an ampersand, the remedy is
simple: Just type `I\&' now. But if some right brace
up above has ended a previous alignment prematurely,
you're probably due for more error messages, and you
might try typing `S' now just to see what is salvageable.

Furthermore, if I just use the left column, then it is displayed all on
one line.

Has someone got this to do anything useful?

I think it was because I had imported a latex document to Lyx, and it
wasn't ticked. It seems to be ticked by default on new documents.

I guess I should file it as a bug? If we don't want to tick it for
imported options, then it ought to raise a warning at the point where it
would have included it... ?

I've thought of such things from time to time, and concluded that the

opinion of "more appropriate space" probably enjoys less acceptance than
their opinion.

However there is a case to make for being able to change it... you just
first need to ask yourself if you are sure that you know better than the
class designers. If you decision is based purely on "it's too wide" then
you probably don't know better and you should leave it alone.

Font sizes in Lyx and Latex are given names:
http://www.image.ufl.edu/help/latex/fonts.shtml

So first you need to think if you literally want "10.5pt" or if you want
to set the size of one of the name styles or sizes to 10.5pt.

You can mess with tie \fontsize{}{} command; insert this in your pre-amble:

\newcommand\sizetf[1]{\begingroup\fontsize{10.5}{12}\selectfont{#1}\endgroup}

then you can use the command

\sizetf{I'm in 10.5pt}

in ERT in your document.

(I wish Lyx supported adding per-document layouts and elements in the
same way that it supports adding Latex commands in the preamble)

You probably want to read this:
http://tkcs-collins.com/truman/latex/list_examp.shtml

And you may find it easier to use these if you define a lyx .module file
to go with them. Look at existing lyx module files to work this out, and
install your own in ~/.lyx/layouts

Sure, but as you can't embed a layout module in the lyx document, ERT
can sometimes be easier and more portable, and for small chunks of text
is already clearly delineated in the Lyx document by the red box.

(I suggested a layout module for his enums, it would be nuts to do those
with ERT)

\index expressions

[Sam Liddicott]

I'm trying to extend the indexing of newfangle literate code chunks.

I'm: \usepackage{index}

so that I can have multiple indexes; but the \index{} command seems to
literally interpret the first parameter, so that
\index{\chunkname}
indexes "\chunkname" instead of the name.

I've tried all kinds of use of \expandafter and other tricks with
secondary macros, like this:

\def\ch...@index#1{%
  \...@index[chunks]{#1}%
}%
\def\Chunk#1{%
  \lstset{title={\newfanglecaption},name=#1}%
  \global\edef\...@chunkname{\lst@intname}%
  \expandafter\ch...@index{\lst@chunkname}%
}%

But even then I get the literal text "\...@chunkname" as the indexed item.

The only thing that "nearly" works is if I pass #1 within \Chunk, but
then I get other text too, which I want to chop off.

Any clues on how to make the index package take an expression?

Sam

Re: \index expressions

[Sam Liddicott]

The Texbook says:

  The \write command is somewhht special, 
because its token
list is first read without expansion; expansion occurs later, when the 
tokens are actually

being written to a file.


As \index writes to a file, this may be the problem!

I'll see if I can do any tricks with
\def\trick#1
where  is delimiters to try and the name it out of the original 
text, as #1 macros seem to make it through fine...

Your message has:

From: "Manveru" 

which is not helpful.

I'm currently sorting based on To: or Cc: having lyx-users@lists.lyx.org
which sadly also selects messages that were emailed to me.

I'll have to have my sorting rules like this:

1. sort all list-id mailing lists
2. select all messages To: or Cc: me
3. sort all To: Cc: mailing lists

and that still won't catch Bcc messages to me (or Lyx).

So I just sort based on to or cc and swear and cuss from time to time
about the Lyx mailing list not supporting list-id header; and generally
fail to notice messages also sent directly to me as it's a thread I'm

sure, list-id should be added by the list server.

Unwritten rules aren't rules; I generally do reply-to-all which is the
natural way to reply to all people. For most of my mailing lists it
means that the named recipients get their message from me, and the
mailing list suppresses the message to them as they are already listed
in the Cc or To headers -- although some mailing lists don't do that.

For sure, I don't generally do that.

The Delivered-To: header is not the same as the list-id header - I'm
more interested in how the message reached me (via the list or not),
Delivered-To: signifies something else, and my mail server does not
support it.

Karmic Koala update slows down lyx

[Sam Liddicott]

The most recent Karmic Koala updates make updating the Lyx caret (text 
position) very slow.


If I click the left-arrow, it takes a second before the caret is seen in 
the new position and the old position is not erased properly.


This may not be a problem with Lyx, but I'm curious to know if other 
users have the same problem.

What is Karmic Koala?


The next Ubuntu release (9.10)

PS: On Fridays I would have suggested to look at
http://lmgtfy.com/?q=karmic+koala ;-)


Well, I already googled it myself ;-). It is nevertheless a strange that 
people asking for help while the list members first have to google what 
they are talking about.


It is perhaps not so strange; I just guessed wrongly between "tediously 
verbose" and "obtusely arcane" - either of which has the potential to be 
annoying - however the joy of such public communication is the 
incidental widening of everyone's horizons.


I could had said "The Ubuntu GNU/Linux distribution alpha release Karmic 
Koala" but at the time even "Ubuntu Karmic Koala" seemed unnecessarily 
verbose. I shall take your tip, though, and presume that not everyone is 
so familiar with the progress of Ubuntu.



Back to the topic Ubuntu 9.10 is not stable and in beta state.


Heh, it's alpha 5 right now.


 I'm wondering why we should care about an unreleased OS.


Here's some reasons, although I don't propose that you personally  adopt 
any of them:

* Other mailing list members care
* It's a chance to spot problems before release
* Other Lyx users care

By using alpha Karmic Koala I was able to spot and report bugs in qemu 
and rhythmbox so that they will be fixed before release.


I'm not asking for support here on this issue, I'm only asking if anyone 
else has noticed this, as I may be able to get information to help me 
investigate further.


So far the problem has only shown itself on computers with nvidia 
drivers, my ATI machine does not show the problem. I'll investigate more 
when I get back to my nvidia machines.


To answer Steve Litt's question, I'm using lyx 1.6.3 (I don't know how 
to ask dpkg where it was built as I do for rpm's but I suspect it is a 
Jaunty Jackalope getdeb build), and qt 4.5.2

Actually nothing stops you from compiling the latest LyX release on
the Ubuntu release in question and use it. It's just not click&run.
That's the price of diversity you pay for a more open operating system.
There is a benefit you get when you pay for a more closed plattform like
Windows or Mac OS (in this case: as long as there are community members
carring to provide builds - so thank the people doing the work).


You are quite right.

It seems to be a QT problem associated with nvidia drivers and compiz.

If you search in http://www.ctan.org/ you can find some latex extensions 
to do such things, so you could produce separate .latex files which you 
can then insert into your Lyx document.


Or you can use dia to produce the diagram - Lyx can allow you to insert 
a dia diagram, and will convert it for you.


Or (and someone else will have to explain how, or point to the right Lyx 
help page) use another favourite drawing tool and define a convertor for 
lyx; or you can have it export an eps which Lyx can import.

Do you want to reference other parts of the document or other listings?

If you use newfangle:
http://repo.or.cz/w/newfangle.git

then you can create references between code blocks, or references within 
the document to a code block from the document, using the \chunkref{} 
command.


However you may want to consider using the lstset escapeinside option.

Newfangle uses:
  \lstset{escapeinside={=<}{>}}
You could put this in the document preamble directly:

You can then insert LaTeX like this:

=<\ref{myref}>

in the listing - sort of like an ERT for listings.

I used =< and > for the latex delimiters because =< is not valid in any

mmh... no, I don't think this is what I'm trying to do. I would like to insert
inside a listing a reference to other parts of the document, a Chapter for
instance, or an equation. For examples, in a C listing I could have:

// According to Equation() I can compute...

So that I have a reference to an equation inside the listing.
Is this possible?
Thanks!
  

Yes, I just told you how:
Put this in your document pre-amble

\lstset{escapeinside={=<}{>}}

Then in your listing put:

=<\ref{myref}>

where myref is your reference.

The =<...> behaves like ERT but for listings.

textcomp Error: symbol \textuparrow not provided by

Having just added a symbol up-arrow, every time I build my PDF, Lyx 
gives this error:


textcomp Error: symbol \textuparrow not provided by

The arrow is in a LyxCode environment, but further testing shows that it

as it works anyway, any tips to stop it complaining?

Phantom spaces

In the attached lyx file, phantom at the beginning of a line results in

I'm also thinking what about a phantom text style (as text styles can be

The luximono font does not yet provide a glyph for the uparrow 
character. It would be nice if you could report this to the luximono 
developers. Perhaps the next version of the luximono fonts will then 
contain some more glyphs.

For now, you need to use another font, for example Latin Modern Typewriter.


Thanks for the tip. I will report it.
I find it interesting that the up-arrow still rendered, but that the 
error stopped lyx's latex run (and second run to resolve references).


It seems like latex or lyx half works around this.

This is the correct behaviour: When a LaTeX-error occurs, LyX stops 
because LaTeX stops. That this raises a LaTeX error instead of a LaTeX 
warning is another issue of the luximono fonts.



Fair enough.

I did submit a report to Bigelow and Holmes about luxi-mono.

I suppose another fix would be a package that redefines \textuparrow{} 
(etc) to switch font if running under the ul9 font.


I'll try and work out how to do that.

They were already installed for me, I wonder if Lyx should offer this as 
an available typewriter font. I also think lyx ought to do 
poor-mans-bold (perhaps by redefining bfseries), I could probably do 
this if the idea is reasonable to the Lyx maintainers. I've certainly 
spent HOURS trying to get bold to work for a typewriter font.

So some work may need to be done, but we don't see a lot of requests for

One of the reasons for so few requests could be that the nifty feature

the GUI, it is not much simpler. After having written a math
expression (say, 'x+x'), right-clicking on the math env will not show
anything CAS-related, while the math toolbars do not propose anything

Thus, to discover the CAS support in LyX a user would need to go the

accessing the Edit > Math > Use CAS menu.

Most people agree that collaboration tools in latex lag behing word/gdocs.
LyX has track changes, but it's very hard to convince collaborators to use
it.
It'd be good to keep an eye on this. Office will come up with online
versions for Office 2010. If every other tool has a cloud version, LyX will
be perceived as old-style and it'd be even harder to convince collaborators


Rich xml formats with overlapping features allow conversions to be done

Perhaps google docs can be used as a collaboration back end, with xslt 
conversion to lyx's new xml format locally.
