Converting text into PDF

enscript cannot do the job. I always cannot figure out how to change the font for enscript output, and the language support for highlighting in enscript is limited. With pygmentize and xelatex, we can do a better job.

Synopsis

usage: mintscript.py [--columns COLUMNS] [-2] [-1] [-b HEADER] [-B] [-c]
                     [-C [LINE_NUMBERS]] [-E [HIGHLIGHT]] [-f NAME] [-F NAME]
                     [--fancy-header [NAME]] [-h] [-I CMD] [-j] [-M PAPER]
                     [-p FILE] [-q] [-r] [-R] [-s NUM] [-T NUM] [-u TEXT] [-V]
                     [-X NAME] [--color [bool]] [--filter-stdin NAME]
                     [--footer FOOTER] [--help]
                     [--margins LEFT RIGHT TOP BOTTOM]
                     [--mark-wrapped-lines [STYLE]] [--style STYLE]
                     [--swap-even-page-margins] [--toc] [--ul-angle ANGLE]
                     [--ul-font NAME] [--ul-gray NUM] [--ul-position POS]
                     [--ul-style STYLE] [--word-wrap]
                     [--geometry-args OPTION [OPTION ...]]
                     [--fontspec-args OPTION [OPTION ...]]
                     [--minted-args OPTION [OPTION ...]]
                     [file [file ...]]

Requirements

It invokes xelatex command with -shell-escape option. The LaTeX code generated will use minted package, which in turn calls pygmentize command to format source code. It uses fancyhdr package for header and footers and tikz package for page underlays (i.e. watermarks). Font support is provided by fontspec package. By default, it expects a font named "Inconsolata" available and accessible by fontspec. This has been tested with TexLive 2017. An older version of TexLive or older version of LaTeX packages may not compatible.

Example and output

Most arguments are same as that of enscript. The following command

$ mintscript.py -M a4paper --footer 'sample output' -u 'TESTING' -r -2 <some_plain_text_file>

Generates the following LaTeX code and run through XeLaTeX to generate the PDF, in the same directory as the input file.

\documentclass{article}
\usepackage[xetex,twocolumn,a4paper,landscape,margin=15mm]{geometry}
\usepackage{amssymb}

\selectfont
\node[text=black!20.000000!white,rotate=45.000000] at ($(current page.center) + (0,0)$) {TESTING};
\end{tikzpicture}}
\fancyfoot[C]{\Headerfont\fontsize{8pt}{8pt}\selectfont{}sample output}
\begin{document}
\fontsize{8pt}{8pt}\selectfont
\inputminted[breaklines,breakanywhere]{text}{source0.txt}

\label{LastPage}
\end{document}

XeLaTeX is used in order to make use of TTF available in the system. Currently we set all fonts used in the LaTeX document to be the same (default Inconsolata, adjustable by -f option). Additional options pass on to geometry package, set font command of fontspec package, or \inputminted command of minted package are allowed via the options --geometry-args, --fontspec-args, --minted-args, respectively.

Intermediate files will be generated for and by LaTeX system but they will be cleaned up automatically.
