This is a recent effort at writing a very light Latex build wrapper for Python 3 using Jinja2 templates. It was inspired by the build philosophy found inhttp://pythonhosted.org/latex/ . However, the original latex library made it difficult to do complex, non-pdf builds (such as compiling to HTML). This repository creates simple components that can be used to build Latex from Jinja2 templates without losing control of the lower-level command line tools provided with latex (like pdflatex and htlatex). The usefulness of the library is split into two components:
- Rendering Jinja2 templates for Latex
- Compiling the rendered template with Latex
Currently, the following output formats are supported out of the box:
- .html
- .docx
That said, given the granular control offered by this package, as long as you stick with formats that are supported by build tools distributed with texlive, you should be able to easily write your own output format extensions using this package as a base.
This project is available athttps://pypi.python.org/pypi/latexbuild and may be installed with pip. I strongly recommend the usage of a virtual environment.

Latex is a great typesetting engine for large, complex projects. However, its native build tools lack a straightforward templating engine where multiple people can collaborate on a similar document. For example, imagine a scenario where five professors in the same department need to create a course syllabus. Grading requirements may be standardized at the department level, which individual lessons are up to the professors. If course syllabuses were created using Jinja2 templating and Latex, the department could create a base template that listed the department standards and ask the professors to extend the base template for each course's syllabus. That way, the professors need not worry about cross-course content or department-wide formatting requirements: these would be handled by the base template.
Assume the department saves the following content intemplate.tex:
% FILENAME: template.tex\documentclass[12pt]{article}\title{Economics Department:\BLOCK{block title}\BLOCK{endblock}}\author{\vspace{-5ex}}\date{\vspace{-5ex}}\begin{document}\maketitle\section{Department Introduction}This is a standard message from the departmentthat will appear in every syllabus in exactly this place.Professors shouldn't have to think about this.\section{Greatness}\BLOCK{block greatness}\BLOCK{endblock}\section{Boredom}\BLOCK{block boredom}\BLOCK{endblock}\end{document}
Now that the template has been created, the accounting professor can create his syllabus in the following way:
%- extends "template.tex"% FILENAME: accounting.tex%- block titleAccounting%- endblock%- block greatnessThis is a great, accounting-specific block%- endblock%- block boredomThis is a boring, accounting-specific block%- endblock
Additionally, the statistics professor can create her syllabus as follows:
%- extends "template.tex"% FILENAME: statistics.tex%- block titleStatistics for juggernauts%- endblock%- block greatnessThis is a great, statistics-specific block%- endblock%- block boredomThis is a boring, statistics-specific block%- endblock
Most Jinja2 templating functionality is supported, using the same syntax alterations as the latex python package referenced in this README's introduction. For example, if you would like to loop over values and place them in a Latex list, you may use the following code.
This snippet provides an ordered list displaying thelist variable passed from Python:\begin{enumerate}%- for variable in variable_list\item\VAR{variable}%- endfor\end{enumerate}Alternatively, this snippet provides an unordered listdisplaying the list variable passed from Python:\begin{itemize}%- for variable in variable_list\item\VAR{variable}%- endfor\end{itemize}
This section will continue being updated over time with more examples.
For the simplest project, you can build a Jinja2-templated latex source repository with the following code:
fromlatexbuildimportbuild_pdf,build_html,build_docx,render_latex_templatePATH_JINJA2="/path/to/your/latex/jinja2/root"PATH_TEMPLATE_RELATIVE_TO_PATH_JINJA2="template/filepath.tex"PATH_OUTPUT_PDF="/path/to/your/output/directory/MYOUTPUTFILE.pdf"PATH_OUTPUT_HTML="/path/to/your/output/directory/MYOUTPUTFILE.html"PATH_OUTPUT_DOCX="/path/to/your/output/directory/MYOUTPUTFILE.docx"# Build Jinja2 template, compile result latex, move compiled file to output path,# and clean up all intermediate filesbuild_pdf(PATH_JINJA2,PATH_TEMPLATE_RELATIVE_TO_PATH_JINJA2,PATH_OUTPUT_PDF)build_html(PATH_JINJA2,PATH_TEMPLATE_RELATIVE_TO_PATH_JINJA2,PATH_OUTPUT_HTML)build_docx(PATH_JINJA2,PATH_TEMPLATE_RELATIVE_TO_PATH_JINJA2,PATH_OUTPUT_DOCX)# If you just want the rendered template's text in a python variable,# do the following (assuming you have no variables to pass):render_latex_template(PATH_JINJA2,PATH_TEMPLATE_RELATIVE_TO_PATH_JINJA2)# If your template renders Jinja2 variables, most interfaces provide# a dictionary parameter. See below for an example for simply# rendering the template's text in PythonDICT_VALS= {'var1':'my variable 1 value','list_var': ['item 1 for analysis','item 2 for analysis'] }render_latex_template(PATH_JINJA2,PATH_TEMPLATE_RELATIVE_TO_PATH_JINJA2,DICT_VALS, )
For more complex builds, the system is designed to accept whatever command line arguments you wish to use. Please see the source file latexbuild/build.py and read the LatexBuild class's documentation for more information.
