I have two files, a.tex and b.tex. In a.tex I have a label, \label{stuff}. In b.tex I need to refer to this label, \ref{stuff}.
I also have a main.tex file. Regardless of if I use \include{a}\include{b} or use \input{a}\input{b} the reference is not included in the pdf generated from main.tex.
The document type of main.tex is tufte-book.
Ideas?

I need to compose a simple rmarkdown file, with text, code and the results of executed code included in a resulting PDF file. I would prefer if the source file is executable and self sifficient, voiding the need for a makefile.
This is the best I have been able to achieve, and it is far from good:
#!/usr/bin/env Rscript
library(knitr)
pandoc('hw_ch4.rmd', format='latex')
# TODO: how to NOT print the above commands to the resulting .pdf?
# TODO: how to avoid putting everyting from here on in ""s?
# TODO: how to avoid mentioning the file name above?
# TODO: how to render special symbols, such as tilde, miu, sigma?
# Unicode character (U+3BC) not set up for use with LaTeX.
# See the inputenc package documentation for explanation.
# nano hw_ch4.rmd && ./hw_ch4.rmd && evince hw_ch4.pdf
"
4E1. In the model definition below, which line is the likelihood?
A: y_i is the likelihood, based on the expectation and deviation.
4M1. For the model definition below, simulate observed heights from the prior (not the posterior).
A:
```{r}
points <- 10
rnorm(points, mean=rnorm(points, 0, 10), sd=runif(points, 0, 10))
```
4M3. Translate the map model formula below into a mathematical model definition.
A:
```{r}
flist <- alist(
y tilda dnorm( mu , sigma ),
miu tilda dnorm( 0 , 10 ),
sigma tilda dunif( 0 , 10 )
)
```
"
Result:
What I eventually came to use is the following header. At first it sounded neat, but later I realized
+ is indeed easy to compile in one step
- this is code duplication
- mixing executable script and presentation data in one file is a security risk.
Code:
#!/usr/bin/env Rscript
#<!---
library(rmarkdown)
argv <- commandArgs(trailingOnly=FALSE)
fname <- sub("--file=", "", argv[grep("--file=", argv)])
render(fname, output_format="pdf_document")
quit(status=0)
#-->
---
title:
author:
date: "compiled on: `r Sys.time()`"
---
The quit() line is supposed to guarantee that the rest of the file is treated as data. The <!--- and --> comments are to render the executable code as comments in the data interpretation. They are, in turn, hidden by the #s from the shell.
I am trying to loop through a set of pdfs (all are OCR'd) in a set of folders and search for key terms in the pdf and if pdf contains a certain term, then save the folder name, file name, etc.. This code is working to an extent. Except, it is missing a few pdfs within the search terms. The reason is because when I read in a couple of the pdfs it displays some jibberish (to me at least) on a couple of pages. For example, say I have read in a pdf named 'the_one.pdf'. It has 278 pages. When I go into adobe acrobat to search this document, I can find 'Search Term 1' on page 171, but when it is read with python, python outputs something like this:

Of course, it displays the majority of pages correctly, but for some reason it won't display a couple of them. For confidentiality reasons, I can't post the pdfs. Does anyone have any idea why this is happening?
Also, anything you can point out to speed up my code or make it more dynamic is helpful as well. Always looking to learn.

Parsing PDF is a complex task, the 1.7 spec has around 750 pages and Adobe makes money with it - thats why it works for them.
PDFs internally have tables that hold
"how letters look" (glyphs)
"what unicode letters those glyphs are mapped to" (you need that to copy&paste someting from pdf correctly)
and a cross-ref which glyph mapps to what unicode. Fonts might be (partly) be embedded in the pdf as well.
Thats (one reason) why pdfs can look 100% ok, could be "OCR"ed ok - but if you just copy&paste from a document that has a corrupt mapping between glyphs and unicode points, you only get gibberish.
I have heard some programms even provide unicode mappings for all glyphs but they do not match up at all ... on purpose (or bad quality) - to prevent copy&paste.
Bottom line: you can try to re-OCR some pages, you could use Adobe Acrobat PRO to extract text from PDF (it has build in ocr features) that give you gibberish or just skip it.
You can try some other pdf-reading framework, maybe they got something not quite right - but chances are slim if it almost always works but just not for a few special pdfs.
I am just a novice in pdf - there are some more advanced ppl around to pipe in on this - but if you cannot share the pdf its going to be hard to advice anything.
Alternate approaches: Searching text in a PDF using Python?
I ran lhs2Tex on my f.lhs file ($ lhs2Tex f.lhs > f.tex). It completed successfully, creating f.tex and producing no errors.
However, when I then run $ pdflatex f.tex, I get (some output followed by) the following error:
Runaway argument?
\ignorespaces \SaveRestoreHook \column {B}{#{}>{\hspre }l<{\hspost }#\ETC.
! File ended while scanning use of \PT#scantoend.
<inserted text>
\par
<*> core.tex
?
Why is the output of lhs2Tex failing to compile to valid tex? It seems that lhs2Tex should not generate invalid tex, even with invalid input.
I am not sure of the best way to debug this; the error message that I have points to f.tex, but that is a long generated output, not my written code. In my code (f.lhs), I am not sure where to start since lhs2Tex sends it to f.tex with no errors or output at all.
Any suggestions on how to approach debugging this?
Edit:
I removed a bunch of the generated code while checking to ensure that what remained still caused the same error.
Here is what remains; this minimized version of f.tex causes the same error.

In my code I have the following line:
fprintf(logfile,'Parameters: Size: %d\tH: %.4f\tF: %.1f\tI: %.3f\tR: %d\tSigma: %d\tDisp: %.1f\r\n',parameter_sets(ps,:));
which is too long, so I want to break it to:
fprintf(logfile,'Parameters: Size: %d\tH: %.4f\tF: %.1f\tI: %.3f\tR: ...
%d\tSigma: %d\tDisp: %.1f\r\n',parameter_sets(ps,:));
However, since the brake is within a string, MATLAB see the formatting %d sign in the second line as a start of a comment, and ignore this line (and produce an error...).
So I tried to make it clearer with a [] that warp the string:
fprintf(logfile,['Parameters: Size: %d\tH: %.4f\tF: %.1f\tI: %.3f\tR: ...
%d\tSigma: %d\tDisp: %.1f\r\n'],parameter_sets(ps,:));
but no help, it still interpret the second line as a comment. I also tried with and without the ellipsis (...) in different places, with no success.
So how can I write a line in a formatted way (i.e. a reasonable length) if it has a % sign in it?
Divide it in two lines like this:
fprintf(logfile,['Parameters: Size: %d\tH: %.4f\tF: %.1f\tI: %.3f\tR:', ...
'%d\tSigma: %d\tDisp: %.1f\r\n'],parameter_sets(ps,:));
% notice the apostrophe and comma(',) before ellpsis(...) at the end of first line
% and apostrophe(') at the start of the second line
I have the following code block in my .lhs file which uses inline TeX comments:
\begin{code}
main = print 0
{-"$\langle$Link$\rangle$"-}

% This package provides two environments suitable to take the place
% of hscode, called "plainhscode" and "arrayhscode".
%
% The plain environment surrounds each code block by vertical space,
% and it uses \abovedisplayskip and \belowdisplayskip to get spacing
% similar to formulas. Note that if these dimensions are changed,
% the spacing around displayed math formulas changes as well.
% All code is indented using \leftskip.
%
% Changed 19.08.2004 to reflect changes in colorcode. Should work with
% CodeGroup.sty.

The {-" ... "-} construct is quite low-level. It drops you in the environment TeX currently is in, which happens to be math mode already. So the solution to your problem is simple. Write the code to be inserted as if you are in math mode.
A different option is to use a normal comment, but make the comment characters invisible using \invisiblecomments. Normal comments are typeset as text by lhs2TeX.
The following complete lhs2TeX document demonstrates both options:
\documentclass{article}
%include polycode.fmt
\begin{document}
% Assume you are in math mode already:
\begin{code}
main = print 0
{-"\langle\text{Link}\rangle"-}
\end{code}
% This works, too:
\invisiblecomments
\begin{code}
main = print 0
{- $\langle$Link$\rangle$ -}
\end{code}
\end{document}
