fmt 和命令行命令(例如 mylatexformat)

fmt 和命令行命令(例如 mylatexformat)

我想加快编译过程,因此我将主文档分成两个文件:

平均能量损失

序言.tex

\documentclass{article}

\csname endofdump\endcsname

主文本

\begin{document}

\ifdefined\test
    :)
\else
    :/
\fi

\end{document}

这有效:

#!/bin/bash

pdftex -ini -jobname="preamble" "&pdflatex" mylatexformat.ltx "preamble.tex"
pdflatex -fmt preamble "main.tex"

问题

但是,我想将数据从命令行传递给 tex 以获得快乐的笑脸,

#!/bin/bash
pdftex -ini -jobname="preamble" "&pdflatex" mylatexformat.ltx "preamble.tex"
pdflatex -fmt preamble "\def\test{1}\input{main}"

我偶然发现了一个交互模式,我不知道该怎么做。使用-不解析第一行也没什么帮助。

答案1

我不是这方面的专家,但我猜mylatexformat不会递归扫描输入文件,因此永远不会遇到\begin{document}文字main.tex文字,而根据其格式,这是标记格式结束所必需的文档. 至少对于您的 MWE 来说,如果您在命令行上发出\endofdump(标记格式结束的替代方法,以避免两个),它就会起作用:\begin{document}

pdflatex -fmt preamble "\endofdump\def\test{1}\input{main}"
