I want to iterate all images in a certain directory and import each image with \includegraphics
from within the MainInput.tex
. The batch file IterateFiles.bat
helps us to create a list of image names in the specified directory.
rem IterateFiles.bat
echo off
rem %1 represents the path (relative to the main input file) to the files to be iterated
rem %2 represents the output file name
rem the remaining args represent the extensio of file to be iterated
set curdir=%CD%
cd %1
shift
set output=%curdir%\%1.list
copy nul %output%
shift
:loop
if "%1"=="" goto :eof
dir /b *.%1 >> %output%
shift
goto :loop
The current implementation of \IterateFiles
macro takes 3 arguments. The first 2 arguments are the path (relative to the MainInput.tex
) to the directory in which images are saved. The bad thing here is that we need to specify the same path in 2 forms: ..\dirsep Images\dirsep
and ../Images/
.
% MainInput.tex
\documentclass{article}
\usepackage{graphicx}
{
\catcode`\^0
\catcode`\\12
^gdef^dirsep{\}
}
\newread\myfile
\newcount\TotalFiles
\makeatletter
\newcommand{\IterateFiles}[3]{%
\immediate\write18{IterateFiles #1 \jobname\space #3}
\openin\myfile=\jobname.list\relax
\loop
\read\myfile to \mydata
\unless\ifeof\myfile
\filename@parse{\mydata}
\section*{\mydata}
\includegraphics[width=\textwidth,height=\textheight,keepaspectratio]{#2\filename@base}
\advance\TotalFiles1\relax
\repeat
\closein\myfile
}
\makeatother
\begin{document}
\IterateFiles{..\dirsep Images\dirsep}{../Images/}{jpg png pdf eps}
\section*{Summary}
There are \the\TotalFiles\ files in total.
\end{document}
My question: How to pass a single file path argument ../Images/
(as opposed two arguments) to the above macro?

Use the
xstring
package to replace/
s with\
s (or vice versa):
