Problem with \input files #207

Closed pauloney closed 4 years ago

pauloney commented 4 years ago

From the manul I understand that ``latexdiff'' works fines with commands like \input, but I am having a hard time making it work on the simplest of all examples -- 4 files all in the same directory:

  1. oldsub.tex
  2. newsub.tex
  3. oldinp.tex
  4. oldinpold files.zip

All attached. When I run:

 latexdiff --flatten oldinp.tex newinp.tex > inp-diff.tex

I get a file that does not process:

(./inp-diff.aux) ! I can't find file `{'.

\protect l.44 \input \DIFdelbegin \DIFdel{oldsub} \DIFdelend \DIFaddbegin \DIFadd{news... (Press Enter to retry, or Control-D to exit) Please type another input file name: ! Emergency stop. \protect l.44 \input \DIFdelbegin \DIFdel{oldsub} \DIFdelend \DIFaddbegin \DIFadd{news... No pages of output. Transcript written on inp-diff.log. I have no problems with include files. This is running on the latest version 1.3.2a

You have to write \input{oldsub}, ie. curly braces and no space between command and its argument (as described on page 3 of the latexdiff manual (pdf file) ). For \input I guess one could add some custom preprocessing, but given that the format with the curly braces is the one used by any LaTeX tutorial or help I am familiar with, this is not something I will pursue now. (Thanks for the well-organised bug report and example, though)
