What is the reason for the format parameter? It should be enough to choose the TeX compiler (latex, pdflatex, xelatex, lualatex, etc.).

I got the following error when trying to run a script.

$ node index.js
events.js:85
      throw er; // Unhandled 'error' event
            ^
Error: spawn ENOENT
    at exports._errnoException (util.js:742:11)
    at Process.ChildProcess._handle.onexit (child_process.js:1028:32)
    at child_process.js:1109:20
    at process._tickCallback (node.js:343:11)

After some digging I found out it was because something went wrong with my latex installation, and so there was no latex application that could be found. IMO this error should be better handled. I can see an error like this being fairly common: handling it to log a No latex installation found or something would be greatly appreciated!

Hi guys,

I'm trying to use LaTeX's graphicx package to include a JPEG image in a template, but the package doesn't seem to render that image. I might be omitting something of course, but I have included my code below for your consideration.

`var fs = require('fs');

var input = process.argv[2];
var output = process.argv[3];
var trog = [];

fs.readFile(input, 'utf8', function (err, data) {
if (err) throw err;
console.log('>>> Tex file imported.');
trog.push(data);
var options = { 'command': 'pdflatex' };
require('latex')(trog, options).pipe(fs.createWriteStream(output));
console.log('>>> Tex file built.');
});`

My tex file is as follows:

\documentclass{article} \usepackage{graphicx} \begin{document} \begin{center} \includegraphics[scale=1]{logo.jpg} \newline \Large NOTICE \end{center} \sffamily Account Number: \textit{12345678} \newline \newline MR A TEST \newline 2 THE STREET \newline FARNBERRY \newline CLOUD TOWN \newline GU15 3AA \newline \newline Amount: 1078.52 \newline Financial Year: \textbf{2017} \newline \newline \small{Footer text} \end{document}

If I run compile this tex file from the terminal using the command pdflatex the image renders fine. Are you able to help me in rendering the included image please?

Thanks.

It looks like this library can't render documents that need to be run through latex multiple times (many of them).

latexmx seems to be a LaTeX wrapper that does this, but it needs specific command-line arguments.

There is an old version of library in npm. For example, there is no errors messages when latex is not installed.

The current version of "node-latex" uses version 0.5.x of the module "temp". This version automatically removed the tempory directory at exit (maybe your explicit remove calls aren't necessary?). Sometimes for debugging it would be helpful if the temporary directory is not deleted at the end. I suggest an additional parameter "keep" for the options object which defaults to false. In the current version of "temp" "track()" or "cleanup()" must be called explicitly for clean up. Thanks.

This will not work as long as we'll want to produce 2 LaTeX simultaneously - as well as it needlessly accesses the filesystem (which may fail for whatever reasons).

User does not really know if the processing has been done correctly - only gets notified if an error occurs. A notification of "ready" after LaTeX has completed its processing would be handy.

Hi, thanks for writing this module. Here is an example of how I am using this:

var fs = require('fs');
var latex = require('latex');

var string = getTexDocument(); // Returns a string of .tex code
var writeStream = fs.createWriteStream('doc.pdf');
latex(string).pipe(writeStream);

This works for most situations, but what do I need to do if the string is a TeX document that wants to use a CLS file? Is there something I can do to pass CLS code as a string as well to make this work? Thanks!

Would this library work, if I install latex through pkg on mac?

As the the temporary directory you have /tmp. I think a better choice would be the content of process.env['TMPDIR'] with fall back to /tmp and additional it should be possible to set the temporary directory in the options object.

Since the latex is compiled inside a temporary directory, latex commands that reference relative files are not resolved. Examples are include and input.
