Displaying the Language Name at the Bottom Right

Oct 13, 2025 by wbrum.org 10 views

Introduction

When working with listings in LaTeX, it's essential to have a clear and customizable way to display code blocks. The tcolorbox package provides the tcblisting environment, which can be used to create visually appealing listings. However, sometimes you may need to add custom key-value parameters to the tcblisting environment. In this article, we'll explore how to let \newtcblisting take custom key-value params.

Understanding \newtcblisting

The \newtcblisting command is used to create a new listing environment with custom settings. It's a powerful tool that allows you to define a listing environment with specific key-value parameters. By default, tcblisting provides a set of predefined keys that can be used to customize the appearance of the listing.

Displaying the Language Name at the Bottom Right

One of the common requirements when working with listings is to display the language name at the bottom right corner of the listing. This can be achieved by using the title key and setting it to a specific value. However, to display the language name at the bottom right, you'll need to use the lowered key and set it to title.

Here's an example of how you can display the language name at the bottom right using \newtcblisting:

\documentclass{article}
\usepackage{tcolorbox}
