I have to print Java code that some times reaches 300 columns (characters per line) in A3 paper and whatever editor I use (e.g. textmate) wraps the lines in order to fit in A4 paper.
Any suggestions?
cheers,
Asterios
Your editor undoubtably has either a Page Setup dialog or a Preferences dialogue as part of the Print Dialogue which will allow you to set the Paper Size to use for printing.
Even Notepad supports this
I finally made it to print using enscript. Here is the command I used to print Java code into PDF (and the used the pdf to print).
enscript -r -Ejava -M A3 -C -f "Courier8" input.java -o - | ps2pdf - output.pdf
where:
-r prints in landscape mode
-C prints the line numbers
-f changes the font and size
-M sets the output media to A3 (default is A4)
-Ejava adds syntax highlighting (you can also use --color if you need
colors in syntax highlighting but
they are not nicely printed in
greyscale)
It seems unlikely that every editor tries to format for A4. Which other editors have you tried? Does textmate not have a page size option? (Hmm... seems not)
Try a different editor that does let you set page size. Word, even.

Working on a project where I'm printing really long prints on epson thermal printers (80mm x 18000mm) (length is variable per print).
My documents are set up as 1000mm long pages ie 14000mm print is 14 pages.
I'm able to print a correct length document with this command
lp -d 10_0_0_11 -o media=Custom.80x18000mm -o PageSize=Custom.80x1000mm -o TmtPaperSource=DocNoFeedCut -o landscape -o fit-to-page -o outputorder=reverse -o TmtSpeed=1 -o TmtPaperReduction=Both example/url/to/document
But this is really slow and don't want to use the command line for convenience.
When printing the document via Preview MacOS it only prints a portion of the document at the printer's max print size of 80x297mm. I have a custom page size of 80x1000mm setup but it seems to be ignoring that.
Any better workaround to gain the extra speed printing without the command line?
What syntax do I use to print "hello world" in the output window?
I simply want to specify the text in the syntax and have it appear in the output.
You need the title command:
title 'this is my text'.
Note that the title can be up to 256 bytes long.
Alternatively, you could use ECHO also. ECHO is useful for debugging macro variable assignements where as TITLE is useful for neat/organised presentation of your tables with intension to perhaps export output results.
If you want to write arbitrary text in its own block in the Viewer rather than having it stuck in a log block, use the TEXT extension command (Utilities > Create text output). You can even include html markup in the text.
If you don't have this extension installed, you can install it from the Utilities menu in Statistics 22 or 23 or the Extensions menu in V24.
example:
TEXT "The following output is very important!"
/OUTLINE HEADING="Comment" TITLE="Comment".
Outfile here is used in an ambiguous way. The prior two answers (the TITLE and ECHO commands) simply print something to the output window. One additional way to print to the output window is the PRINT command.
DATA LIST FREE / X.
BEGIN DATA
1
2
END DATA.
PRINT /'Hello World'.
EXECUTE.
If you do that set of syntax you will actually see that 'Hello World' is printed twice -- one for each record in the dataset. So one way to only print one line is to wrap it in a DO IF statement and only select the first row of data.
DO IF $casenum=1.
PRINT /'Hello World'.
END IF.
EXECUTE.
Now how is this any different than the prior two commands? Besides aesthetic looks in the output window, PRINT allows you to save an actual text file of the results via the OUTFILE parameter, which is something neither of the prior two commands allows.
DO IF $casenum=1.
PRINT OUTFILE='C:\Users\Your Name\Desktop\Hello.txt' /'Hello World'.
END IF.
EXECUTE.
How can I search for control characters in unix ed(1)?
For example
ed somefile.log <<EOF
1,$s/.*\015//
w
q
EOF
doesn't work. Neither does \r. Obviously sed(1), awk(1) and other editors can do this, however ed has the very useful line move (m) command which is all I need within the bash script I am using.
I am able to accomplish what I want within the script by entering the control character directly (escaping it with C-v in vi, C-q in emacs for example), but this means that binary characters must be present in my otherwise printable text script.
ed Transport2SVN-W0177.log <<EOF
g/^M/s/.*^M//p
w
q
EOF
The ^M is actually character 0x0d.
ed doesn't provide any support for converting control characters.
The way you have found of inserting control-characters directly into the script (using Ctrl-V at the keyboard) is portable and it works.
It's possible that particular implementations of ed might support this, but it would not be portable.
I want to make use of Maxima as the backend to solve some computations used in my LaTeX input file.
I did the following steps.
Step 1
Download and install Maxima.
Step 2
Create a batch file named cas.bat (for example) as follows.
rem cas.bat
echo off
set PATH=%PATH%;"C:\Program Files (x86)\Maxima-5.31.2\bin"
maxima --very-quiet -r %1 > solution.tex
Save the batch in the same directory in which your input file below exists. It is just for the sake of simplicity.
Step 3
Create the input file named main.tex (for example) as follows.
% main.tex
\documentclass[preview,border=12pt,12pt]{standalone}
\usepackage{amsmath}
\def\f(#1){(#1)^2-5*(#1)+6}
\begin{document}
\section{Problem}
Evaluate $\f(x)$ for $x=\frac 1 2$.
\section{Solution}
\immediate\write18{cas "x: 1/2;tex(\f(x));"}
\input{solution}
\end{document}
Step 4
Compile the input file with pdflatex -shell-escape main and you will get a nice output as follows.
!
Step 5
Done.
Questions
Apparently the output of Maxima is as follows. I don't know how to make it cleaner.
solution.tex
1
-
2
$${{15}\over{4}}$$
false
Now, my question are
how to remove such texts?
how to obtain just \frac{15}{4} without $$...$$?
(1) To suppress output, terminate input expressions with dollar sign (i.e. $) instead of semicolon (i.e. ;).
(2) To get just the TeX-ified expression sans the environment delimiters (i.e. $$), call tex1 instead of tex. Note that tex1 returns a string, which you have to print yourself (while tex prints it for you).
Combining these ideas with the stuff you showed, I think your program could look like this:
"x: 1/2$ print(tex1(\f(x)))$"
I think you might find the Maxima mailing list helpful. I'm pretty sure there have been several attempts to create a system such as the one you describe. You can also look at the documentation.
I couldn't find any way to completely clean up Maxima's output within Maxima itself. It always echoes the input line, and always writes some whitespace after the output. The following is an example of a perl script that accomplishes the cleanup.
#!/usr/bin/perl
use strict;
my $var = $ARGV[0];
my $expr = $ARGV[1];
sub do_maxima_to_tex {
my $m = shift;
my $c = "maxima --batch-string='exptdispflag:false; print(tex1($m))\$'";
my $e = `$c`;
my #x = split(/\(%i\d+\)/,$e); # output contains stuff like (%i1)
my $f = pop #x; # remove everything before the echo of the last input
while ($f=~/\A /) {$f=~s/\A .*\n//} # remove echo of input, which may be more than one line
$f =~ s/\\\n//g; # maxima breaks latex tokens in the middle at end of line; fix this
$f =~ s/\n/ /g; # if multiple lines, get it into one line
$f =~ s/\s+\Z//; # get rid of final whitespace
return $f;
}
my $e1 = do_maxima_to_tex("diff($expr,$var,1)");
my $e2 = do_maxima_to_tex("diff($expr,$var,2)");
print <<TEX;
The first derivative is \$$e1\$. Differentiating a second time,
we get \$$e2\$.
TEX
If you name this script a.pl, then doing
a.pl z 3*z^4
outputs this:
The first derivative is $12\,z^3$. Differentiating a second time,
we get $36\,z^2$.
For the OP's application, a script like this one could be what is invoked by the write18 in the latex file.
If you really want to use LaTeX then the maxiplot package is the answer. It provides a maxima environment inside of which you enter Maxima commands. When you process your LaTeX file a Maxima batch file is generated. Process this file with Maxima and process your LaTeX file again to typeset the equations generated by Maxima.
If you would rather have 2D math input with live typesetting then use TeXmacs. It is a cross-platform document authoring environment (a word processor on steroids if you like) that includes plugins for Maxima, Mathematica and many more scientific computing tools. If you need to or are not satisfied with the typesetting, you can export your document to LaTeX.
I know this is a very old post. Excellent answers for the question asked by OP. I was using --very-quiet -r options on the command line for a long time like OP, but in maxima version 5.43.2 they behave differently. See maxima command line v5.43 is behaving differently than v5.41. I am answering this question with a cross reference because when incorporating these answers in your solutions, make sure the changes in behavior of those command line flags are also incorporated.
I'm currently searching for an application or a script that does a correct word count for a LaTeX document.
Up till now, I have only encountered scripts that only work on a single file but what I want is a script that can safely ignore LaTeX keywords and also traverse linked files...ie follow \include and \input links to produce a correct word-count for the whole document.
With vim, I currently use ggVGg CTRL+G but obviously that shows the count for the current file and does not ignore LaTeX keywords.
Does anyone know of any script (or application) that can do this job?
I use texcount. The webpage has a Perl script to download (and a manual).
It will include tex files that are included (\input or \include) in the document (see -inc), supports macros, and has many other nice features.
When following included files you will get detail about each separate file as well as a total. For example here is the total output for a 12 page document of mine:
TOTAL COUNT
Files: 20
Words in text: 4188
Words in headers: 26
Words in float captions: 404
Number of headers: 12
Number of floats: 7
Number of math inlines: 85
Number of math displayed: 19
If you're only interested in the total, use the -total argument.
I went with icio's comment and did a word-count on the pdf itself by piping the output of pdftotext to wc:
pdftotext file.pdf - | wc - w
latex file.tex
dvips -o - file.dvi | ps2ascii | wc -w
should give you a fairly accurate word count.
To add to #aioobe,
If you use pdflatex, just do
pdftops file.pdf
ps2ascii file.ps|wc -w
I compared this count to the count in Microsoft Word in a 1599 word document (according to Word). pdftotext produced a text with 1700+ words. texcount did not include the references and produced 1088 words. ps2ascii returned 1603 words. 4 more than in Word.
I say that's a pretty good count. I am not sure where's the 4 word difference, though. :)
In Texmaker interface you can get the word count by right clicking in the PDF preview:
Overleaf has a word count feature:
Overleaf v2:
Overleaf v1:
I use the following VIM script:
function! WC()
let filename = expand("%")
let cmd = "detex " . filename . " | wc -w | perl -pe 'chomp; s/ +//;'"
let result = system(cmd)
echo result . " words"
endfunction
… but it doesn’t follow links. This would basically entail parsing the TeX file to get all linked files, wouldn’t it?
The advantage over the other answers is that it doesn’t have to produce an output file (PDF or PS) to compute the word count so it’s potentially (depending on usage) much more efficient.
Although icio’s comment is theoretically correct, I found that the above method gives quite accurate estimates for the number of words. For most texts, it’s well within the 5% margin that is used in many assignments.
If the use of a vim plugin suits you, the vimtex plugin has integrated the texcount tool quite nicely.
Here is an excerpt from their documentation:
:VimtexCountLetters Shows the number of letters/characters or words in
:VimtexCountWords the current project or in the selected region. The
count is created with `texcount` through a call on
the main project file similar to: >
texcount -nosub -sum [-letter] -merge -q -1 FILE
<
Note: Default arguments may be controlled with
|g:vimtex_texcount_custom_arg|.
Note: One may access the information through the
function `vimtex#misc#wordcount(opts)`, where
`opts` is a dictionary with the following
keys (defaults indicated): >
'range' : [1, line('$')]
'count_letters' : 0/1
'detailed' : 0
<
If `detailed` is 0, then it only returns the
total count. This makes it possible to use for
e.g. statusline functions. If the `opts` dict
is not passed, then the defaults are assumed.
*VimtexCountLetters!*
*VimtexCountWords!*
:VimtexCountLetters! Similar to |VimtexCountLetters|/|VimtexCountWords|, but
:VimtexCountWords! show separate reports for included files. I.e.
presents the result of: >
texcount -nosub -sum [-letter] -inc FILE
<
*VimtexImapsList*
*<plug>(vimtex-imaps-list)*
The nice part about this is how extensible it is. On top of counting the number of words in your current file, you can make a visual selection (say two or three paragraphs) and then only apply the command to your selection.
For a very basic article class document I just look at the number of matches for a regex to find words. I use Sublime Text, so this method may not work for you in a different editor, but I just hit Ctrl+F (Command+F on Mac) and then, with regex enabled, search for
(^|\s+|"|((h|f|te){)|\()\w+
which should ignore text declaring a floating environment or captions on figures as well as most kinds of basic equations and \usepackage declarations, while including quotations and parentheticals. It also counts footnotes and \emphasized text and will count \hyperref links as one word. It's not perfect, but it's typically accurate to within a few dozen words or so. You could refine it to work for you, but a script is probably a better solution, since LaTeX source code isn't a regular language. Just thought I'd throw this up here.
