It's a known fact that context has a different notion of valid file
names than your operating system does. This is by design. To quote
the manual:
“It is highly recommended, that all input files, i.e. the ConTEXt
source and other included files such as image files, have only the
letters a–z, digits and dashes in their names, that is in the
names of their full paths, otherwise you can easily get into
problems.”
I'm writing a ConTeXt document called modern-c++.tex (in OS X 10.7.5). The
content of the file is:
\setupbibtex[database={modern-c++}, sort=author]
\setuppublications[numbering=yes]
\starttext
\completepublications[criterium=all]
\stoptext
Especially since c++ didn't work out, I expected dropping the “++”
would work (“modern-c”), but it didn't. So I ran some tracing:
\enabletrackers [resolvers.readfile]
\starttext
\readfile{file++.ext}{}{}
\stoptext
This reports:
files > readfile > not found by tree lookup: file .ext
Which means the “++” is replaced by two spaces, instead of searching
for “file++.ext” or “file.ext” which is what I had expected. I
didn't dig into the code to check where the spaces creep in.
Regardless if this particular issue gets fixed or not, I doubt that
Hans will put much effort into general support for “esoteric” file
names. So, it's best to avoid plus signs in file names.
indeed. names are parsed as url's (so + become space) so a possible fix is:
function getreadfilename(scheme,path,name)
local fullname
if hasscheme(name) or is_qualified_path(name) then
fullname = name
else
name = url.escape(name) -- yes or no ?
fullname = ((path == "") and format("%s:///%s",scheme,name)) or
format("%s:///%s/%s",scheme,path,name)
end
return resolvers.findtexfile(fullname) or "" -- can be more direct
end
but one cannot predict how this passes further on through the system
also, because one can say:
\readfile{file\letterpercent2B\letterpercent2B.ext}{}{}
the hack in fact should be:
if not string.find(name,"%%") then
name = url.escape(name) -- if no % in names
end
which then handles both
\readfile{file\letterpercent2B\letterpercent2B.ext}{}{}
\readfile{file++.ext}{}{}
ok. Of course, when moving from c++ to c# one gets things like
\readfile{file\letterhash.ext}{}{}
where the # will sometimes confuses macros later on.
