execute exernal programm with tectonic

[LuckyTurtleDev]

The following code works with xelatex --shell-escape latex.tex , but not with tectonic -Z shell-escape latex.tex

\documentclass{report}

\begin{document}

fooo baaa\\
%\input{|"uname -a"}
\input|"ls"

\end{document}

Tectonic returns the following:

Running TeX ...
warning: latex.tex:7: piped inputs from external commands are not implemented in Tectonic
error: failed to open input file "|ls"

The warning says piped inputs are not implemented. Are there any alternatives for this in tecontic?

[rm-dr]

I don't think so, at least not yet. iirc this used to work before (#859), but may have been broken with a recent Rust rewrite.
