No bibliography in the output, depends on file name

No bibliography in the output, depends on file name

[Nicola]

Hi,
maybe this is a known issue, but I couldn't find anything about it, so I'm 
reporting it.

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

(Well, I haven't started to write my notes yet.) When typesetting it, though, no 
bibliography is printed (I've tried with Mark II/IV from MacTeX and with the 
latest Mark IV stable/beta). Renaming the .tex file to cplusplus.tex solves the 
problem (there is no need to rename the .bib file).
 
Nicola

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.”

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.
