bug#28456: 11.90.2.2017-07-25; \\input parsing

[Pierre Lorenzon]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report.  In addition check if the bug is reproducable with an
up-to-date version of AUCTeX.  So please upgrade to the version
available from http://www.gnu.org/software/auctex/ if your
installation is older than the one available from the web site.

If the bug is triggered by a specific (La)TeX file, you should try
to produce a minimal sample file showing the problem and include it
in your report.

Your report will be posted for the auctex package at the GNU bug
tracker.  Visit http://debbugs.gnu.org/cgi/pkgreport.cgi?pkg=auctex
to browse existing AUCTeX bugs.

Hi,

Here is the sample file:

>>>  -- .tex 

\begin{plnpsudpb}{À rendre le 19 octobre 2016}
  \label{PB-I}
  %%
  \input{Introduction}
  %% 
  \input{../../Exercices/Ensembles/Applications-Proprietes}
  %%
  \begin{exercice}[L'addition dans $\Nat$]

   
  \end{exercice}
  %% 
\end{plnpsudpb}
%%% Local Variables: 
%%% mode: latex
%%% TeX-master: "Header"
%%% End: 

>>>  -- End .tex 

And here is the style .el file produced by auctex:

>>>  -- .el 

(TeX-add-style-hook
 "Probleme-I"
 (lambda ()
   (TeX-run-style-hooks
    "Introduction")
   (LaTeX-add-labels
    "PB-I"))
 :latex)


>>>  -- End .el

As if second \input
  \input{../../Exercices/Ensembles/Applications-Proprietes}

were not parsed when first one

  \input{Introduction}

is. In fact looking carefully at regexp used to match \\input
which is part of the LaTeX-auto-regexp-list variable, it
clearly appears that an path like \input{../../something} will
not be parsed.

Question is why? When LaTex allows inputs with so complexe
paths, why are they not parse by auctex?

Surely I can add somehting suitable to the parse variables so
that these inputs will be detected but why is it not done by
default in auctex?


Regards

Pierre
