Hello ConTeXist I met with great strangeness. When I was looking for a mistake in my source text, so I experimented and at one point I renamed myfile so that there are "+" in its name. At that moment compilation ran flawlessly. I know that the use of + in the filename is relatively non-standard, but even so I was surprised Now everything works fine, but I decided to send it as a curiosity rather than to be annoyed by someone. It's really strange and it took me a long time before I discovered the cause of the collapse of the compilation. Unfortunately I am unable to put together a minimal example, which worked, but it is interesting, that compilation will be OK in two cases: 1. when I rename the file to name without "+" or 2. when images are not to be found (for example when I comment the line which contain \setupexternalfigures[directory={flags/}]) Conversely, if "+" is part of the filename, while images are found, the compilation will collapse and prints a message that I mention below. I present here an minimal example (with message list), BUT THAT WILL NOT WORK because they do not have my library, but although the problem probably caused by my library, so it probably is not very important at this point because the problem is maybe a bit wider. Best regards Jaroslav Hajtmar Here is my minimal example. When the file called "list-aaa.tex" so everything is OK. When the file named "list+aaa.tex" and pictures are found, the compilation fails: \usemodule[../../t-scancsv.mkiv/t-scancsv] \setupexternalfigures[directory={flags/}] \def\flagpicture{\externalfigure[\Flag.png]} %\Flag macro is defined by my library \unexpanded\def\tableaction{\expanded{\bTR\bTD\ \flagpicture\eTD\eTR}} \starttext \setheader \setsep{,} \setfiletoscan{lide.csv} \bTABLE \doloopif{\Flag}{~=}{en}{\tableaction} \eTABLE \stoptext And here is message of compilation list: C:\1da\ConTeXt-MkIV\t-scancsv.mkiv\CTMagenda>context --autopdf list+aaa mtx-context | run 1: luatex --fmt="C:/context/tex/texmf-cache/luatex-cache/context/2448223e6631addb83df348d74153606/formats/cont-en" --lua="C:/context/tex/texmf-cache/luatex-cache/context/2448223e6631addb83df348d74153606/formats/cont-en.lui" --backend="pdf" "./list+aaa" \stoptext This is LuaTeX, Version beta-0.70.1-2011061421 (rev 4277) \write18 enabled.
