gammalatex

A simple latex wrapper for the pdflatex binary.

You don't have to worry about rerunning pdflatex in order to get the cross-references right.

Prerequisites

You must have pdflatex installed (or another LaTeX command, see setCompileCommand below).

Linux: sudo yum install texlive-latex

Mac OS: MacTeX

Installation

npm install --save gammalatex

Then var latex = require("gammalatex"); on any node.js file.

API

• .parse(string, callbackFunction)
  string: String containing valid latex syntax
  callbackFunction: A function that will be called after parsing your string. Signature: callbackFunction(err, readStream)

• .setPreParseHook(callbackFunction)
  callbackFunction: A function that will be called before running pdflatex. Signature: callbackFunction(params, cb)

• .setPostParseHook(callbackFunction)
  callbackFunction: A function that will be called after running pdflatex. Signature: callbackFunction(params, cb)

• .addRerunIndicator(string)
  string: A string to check against pdflatex log output to determine whether pdflatex must be rerun.

• .setCompileCommand(object)
  object: An object with one mandatory field: command gives the name of the latex command, for example 'pdflatex', 'xelatex', etc. An optional options field gives an array of additional command-line options. An optional texpath field gives a value for the TEXINPUTS environment variable, used to specify additional search paths for latex files and packages. An optional tmpdir field gives a path for a temporary working directory.

Usage

var 
    util = require("util"),
    latex = require("gammalatex"),
    fs = require("fs");

var string = [
              "\\documentclass{article}",
              "\\begin{document}",
              "Gammasoft Desenvolvimento de Software Ltda",
              "\\end{document}"
              ].join("\n");

latex.parse(string, function(err, readStream){
    if(err) throw err;
    
    var writeStream = fs.createWriteStream("output.pdf");
    util.pump(readStream, writeStream);
});
