Override Job Name and Write Terminal Output to Zip in Java

Introduction

In the world of Java development, Aspose.TeX stands out as a powerful tool for handling TeX file formats. In this tutorial, we’ll delve into a specific scenario – overriding job names and writing terminal output to a zip file. This step-by-step guide will walk you through the process using Aspose.TeX for Java.

Prerequisites

Before we embark on this tutorial, make sure you have the following prerequisites in place:

  • Basic knowledge of Java programming.
  • Installed Aspose.TeX for Java. If not, you can download it from the Aspose website.
  • An understanding of how to set up a Java development environment.

Import Packages

Begin by importing the necessary packages into your Java project. This ensures that you have access to the Aspose.TeX functionalities required for the task.

package com.aspose.tex.OverridenJobNameAndTerminalOutputWrittenToZip;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import com.aspose.tex.InputZipDirectory;
import com.aspose.tex.OutputFileTerminal;
import com.aspose.tex.OutputZipDirectory;
import com.aspose.tex.TeXConfig;
import com.aspose.tex.TeXJob;
import com.aspose.tex.TeXOptions;
import com.aspose.tex.rendering.PdfDevice;
import com.aspose.tex.rendering.PdfSaveOptions;

import util.Utils;

Step 1: Open ZIP Archives

Firstly, open a stream on the ZIP archive that will serve as the input working directory. This is the archive from which your data will be processed.

// Open a stream on the input ZIP archive
final InputStream inZipStream = new FileInputStream("Your Input Directory" + "zip-in.zip");

Step 2: Open Output ZIP Archive

Next, open a stream on a ZIP archive that will serve as the output working directory. This is where the terminal output will be written.

// Open a stream on the output ZIP archive
final OutputStream outZipStream = new FileOutputStream("Your Output Directory" + "terminal-out-to-zip.zip");

Step 3: Set Conversion Options

Create conversion options for the default ObjectTeX format upon ObjectTeX engine extension. Specify a job name and ZIP archive working directories for both input and output.

// Create TeX options for ObjectTeX format
TeXOptions options = TeXOptions.consoleAppOptions(TeXConfig.objectTeX());
options.setJobName("terminal-output-to-zip");
options.setInputWorkingDirectory(new InputZipDirectory(inZipStream, "in"));
options.setOutputWorkingDirectory(new OutputZipDirectory(outZipStream));

Step 4: Specify Terminal Output

Specify that the terminal output must be written to a file in the output working directory. The file name will be <job_name>.trm.

// Specify terminal output settings
options.setTerminalOut(new OutputFileTerminal(options.getOutputWorkingDirectory()));

Step 5: Define Saving Options and Run the Job

Define saving options, such as PDF save options in this case. Run the TeX job to execute the conversion.

// Define saving options and run the job
options.setSaveOptions(new PdfSaveOptions());
new TeXJob("hello-world", new PdfDevice(), options).run();

Step 6: Finalize Output ZIP Archive

After the job is completed, finalize the output ZIP archive to ensure proper completion.

// Finalize the output ZIP archive
((OutputZipDirectory) options.getOutputWorkingDirectory()).finish();

Conclusion

Congratulations! You’ve successfully learned how to override job names and write terminal output to a ZIP file in Java using Aspose.TeX. This powerful functionality adds flexibility and efficiency to your Java development projects.
