[Tex/LaTex] How to influence the name of the pdf file created with pdfLaTeX (from within the source code)

external filesjobname

I have a source file called 2011-05-27_Myfilename.tex and I'd like to create a PDF file from it called only Myfilename.pdf.

Can this be configured from within the .tex file itself?

(It seems to be possible with

pdflatex -jobname=Myfilename.tex 2011-05-27_Myfilename.tex

However, as many different files are concerned, It would be easier to have an option like output=Myfilename in the LaTeX source code.)

I'm afraid you cannot alter the output name from within the LaTeX source: the \jobname primitive can be read but not altered. You can arrange two-file solutions which allow one LaTeX file to 'call' another, but I am not sure that will answer your problem here.

\documentclass{article}
\makeatletter
\def\app@exe{\immediate\write18}
\def\inputAllFiles#1{%
  \app@exe{ls #1/*.txt | xargs cat >> #1/\jobname.tmp}%
  \InputIfFileExists{#1/\jobname.tmp}{}{}
  \AtEndDocument{\app@exe{rm -f #1/\jobname.tmp}}}
\makeatother
\begin{document}

\inputAllFiles{.}% from the current dir 

\end{document}

Not really difficult. It is only an appetizer of how it can be done. This one only reads files *.txt. You have to run it with pdflatex -shell-escape test

Extract multiple information from the \jobname

If I understand your question, you have main file named foo-bar.tex and you need to check if the first part of the job name is foo. You can do this by following macros:

\def\readjobname #1-#2\end{\def\name{#1}\def\lang{#2}}
\def\isname #1\iftrue{\edef\tmp{\detokenize{#1}}\ifx\tmp\name}

\expandafter\readjobname \jobname\end  % reading both parts of the job name

\isname ingmod\iftrue Name is ingmod\else Name isn't ingmod\fi

\isname foo\iftrue Name is foo\else Name isn't foo\fi

\bye

The example above assumes that the job name must be in the form foo-bar. If the hyphen - is missing here, then it fails. But you can do the macro more robust:

\def\readjobname #1-#2\end{\def\name{#1}\def\lang{#2}}
\def\isname #1\iftrue{\edef\tmp{\detokenize{#1}}\ifx\tmp\name}
\def\isindash #1-#2\iffalse{\ifx\relax#2\relax}

\expandafter\isindash \jobname-\iffalse  % reading job name
   \edef\name{\jobname}\def\lang{}
\else
   \expandafter\readjobname \jobname\end
\fi

\isname ingmod\iftrue Name is ingmod\else Name isn't ingmod\fi

\isname foo\iftrue Name is foo\else Name isn't foo\fi

\bye

Now, if there isn't hyphen character then name is full jobname and \lang is empty.
