Normalization rules such as this normally appear to be an excellent
idea, and may not even deserve documentation. But I wonder whether the
present case indicates that the behavior should be changed. At least
the normalization should be done after finding the files rather than before.
Of course, without good reasons to the contrary, having an input source
file in the output directory seems not a good idea. It's even less of a
good idea when there is a file of the same name in the current directory
and one knows that the output directory is necessarily ahead of the
current directory in the search path. But such unusual situations do
Here are my reasons against normalizing the given filename in the way it
is currently done:
1. It violates natural (or naive) user expectations that ./test.tex and
./test refer to a file specifically in the current directory.
2. It violates natural user expectations that ./test and ./test.tex
should refer to the same test.tex file (if it exists).
3. It gives different behavior between the tex programs and kpsewhich.
Suppose I define TEXINPUTS to put the output (or some other) directory
ahead of the current directory and have a file test.tex in both. Then
running both "kpsewhich ./test" and "kpsewhich ./test.tex" return
./test.tex. In contrast "pdflatex ./test" and "pdflatex ./test.tex"
have different behavior.
4. When the file in the current directory is used, the log file reports
it as ./test.tex, which reinforces the user's naive expectation that
using ./test.tex on the command line should specifically select the file
in the current directory.
5. When the file test.tex exists only somewhere else in the kpsearch
path, it won't be found by "pdflatex ./test.tex", unlike the case when
the file is in the output directory.
