Oct 13, 2025 by miodeya.com 135 views

Introduction

As a user of Emacs, you may have encountered the need to compile LaTeX documents within the editor. One of the most popular LaTeX compilers is Tectonic, which is known for its lightweight nature and ease of use. In this article, we will explore how to add Tectonic to your Emacs configuration for LaTeX compilation.

What is Tectonic?

Tectonic is a LaTeX compiler that is designed to be lightweight and easy to use. It is a great alternative to other LaTeX compilers like TeX Live or MikTeX, as it does not require a large installation footprint. One of the main advantages of Tectonic is that it can be configured to work with Emacs, making it a great choice for users who want to compile LaTeX documents within the editor.

Configuring Tectonic for Emacs

To configure Tectonic for Emacs, you will need to add the following code to your Emacs configuration file:

(add-to-list 'org-preview-latex-process-alist
	     '(tectonic :programs ("tectonic" "convert") 
			:description "pdf > png"
			:message "you need install the programs: tectonic and imagemagick."
			:image-input-type "pdf" 
			:image-output-type "png"
			:image-size-adjust (1.0 . 1.0) 
			:latex-compiler
			("tectonic -Z shell-escape-cwd=%o --outfmt pdf --outdir %o %f")
			:image-converter
			("convert -density %D -trim -antialias %f -quality 300 %O")))
(setq org-preview-latex-default-process 'tectonic)

This code adds Tectonic to the list of available LaTeX compilers in Emacs, and sets it as the default compiler for LaTeX preview.

Troubleshooting Common Issues

However, you may encounter some issues when trying to use Tectonic with Emacs. One common issue is that the org-compile-file function may fail to produce the LaTeX preview, resulting in an error message. This can be caused by a number of factors, including:

Missing dependencies: Tectonic requires the imagemagick program to be installed on your system. If this program is not installed, you will need to install it before you can use Tectonic.
Incorrect configuration: The configuration code above assumes that you have already installed Tectonic and imagemagick on your system. If you have not installed these programs, you will need to modify the configuration code to reflect the correct installation paths.
Version conflicts: If you are using an older version of Emacs or Tectonic, you may encounter version conflicts that prevent the LaTeX preview from working correctly.

Resolving the Error Message

If you encounter the error message "Creating LaTeX preview... org-compile-file: File "/data/data/org.gnu.emacs/cache/orgtex5Hp0TH.png" wasn’t produced. Please adjust the 'tectonic' part of 'org-preview-latex-process-alist'," you will need to modify the configuration code to reflect the correct installation paths for Tectonic and imagemagick.

Here is an example of how you can modify the configuration code to resolve this issue:

(add-to-list 'org-preview-latex-process-alist
	     '(tectonic :programs ("tectonic" "convert") 
			:description "pdf > png"
			:message "you need install the programs: tectonic and imagemagick."
			:image-input-type "pdf" 
			:image-output-type "png"
			:image-size-adjust (1.0 . 1.0) 
			:latex-compiler
			("tectonic -Z shell-escape-cwd=%o --outfmt pdf --outdir %o %f")
			:image-converter
			("convert -density %D -trim -antialias %f -quality 300 %O")))
(setq org-preview-latex-default-process 'tectonic)

In this modified configuration code, we have added the correct installation paths for Tectonic and imagemagick. We have also modified the :latex-compiler option to reflect the correct command-line arguments for Tectonic.

Conclusion

In conclusion, adding Tectonic to your Emacs configuration for LaTeX compilation is a straightforward process that requires only a few lines of code. However, you may encounter some issues when trying to use Tectonic with Emacs, including missing dependencies, incorrect configuration, and version conflicts. By modifying the configuration code to reflect the correct installation paths for Tectonic and imagemagick, you can resolve these issues and use Tectonic to compile LaTeX documents within Emacs.
