    I am reluctant to modify the rest2web files. But maybe I missed a
way of doing this without modifying them. Currently I am only coding
embedded code in the template.

    You mean if the file keyword is "foo/bar" rest2web won't create a
foo subdirectory in the target directory and copy bar there ? If so then
I think it would be an interesting feature to add.

    I have been trying to, but I cannot find a way of retrieving the
target directory with embedded code. Are you suggesting that I modify
function.py to add such a function and send you a patch ? I'll have a
look at that.
    If you can give me some advice on implementing that I am more then

    The more I think about it the more I think there is a certain amount
of work. But I think it will be a very useful feature.

    Thanks for such quick feedback (I joined the sourceforge mailing
list and saw your mail).

But you can import anything inside the templates - so keep it in an 
external file somewhere on ``sys.path`` (e.g. your ``site-packages`` 
folder) and import it.

If you wanted to make this easily available, the file to add it to is 
functions.py. If you write a general enough function I will add it to 
the distribution. Ah.. I can see below that you are aware of this file.

I *don't* do this so that you can copy relative files into the target 
directory using the ``file`` keyword.

I think it would be easy enough to create a standard function that does 
this - so modifying the file keyword shouldn't be necessary.

The full path to the page being generated is ``pagepath``.

You should find that ``os.path.dirname(pagepath)`` gives you the 
directory. Let me know how you get on with this.

Well, I've started work on it. It might not be that easy because I need 
to pickle the data structures in use by rest2web. This means I need to 
check that there are no complicated cross references that won't be 
restored properly if I just copy data for individual pages from the pickle.

    Fare enough. You have a point.

    Well unless I am wrong this is the relative path from the root of
the web site. To be able to copy the file from the source tree to the
target tree I also need to know their roots. The root of the source tree
seems to be the current working dir of the script, that I can get with
os.getcwd(), but I have not found a way of accessing the root of the
target directory.

    I get the source directory with :
fullpath=3Dos.path.dirname(os.getcwd()+"/"+pagepath)

    If you know a way of finding out the target directory or the root of
the target tree from either functions.py or embedded code than I can
code a appropriate function.

Ahh.... good point, you need the target directory as well.

You can find this using ``Processor.target``, which is kind of a hack - 
but why I included access to the Processor object.

What values would you like (they are very easy to add into the namespace) ?

    Ha ! I should have investigator the processor object a bit more ( I
had seen that it was in the the namespace)

    Well, you know as well as I do that it is hard to know in advance
what a user might need. I think the root of the target tree would be
enough. Do you confirm that os.getcwd will give me the root of the
source tree or is this just a coincidence that it does on my tests.

    I'll write a function to copy file from the source tree to the
target tree that can be included in functions.py . I'll just wait until
tomorrow in order to have a clearer idea of what options/features might
be wanted for such function.

    Suggestions welcomed.

The current working directory is explicitly set at the start - so you 
can rely on this behaviour.

I'll probably add the target directory as an explicit value.

Ok. The file keyword isn't actually one I use (currently), I guess being 
able to specify a list of source files and a single target directory 
(relative to the current target directory I guess).

    OK, now that I am using Processor.target in my embedded scripts I
can do what I want. But it would be nicer to have a function for do
this. Something like :

def add_file(source, targetdir=3Dos.path.dirname(Processor.target+"/"+pag=
epath)

    Where source could be either a string or a tuple of strings.

    Trying to implement this I realize I do not know how to access
pagepath or Processor in functions.py . Maybe it would be nice if the
namespace accessible to the embedded functions was also accessible in
functions.py (note that I have no clue how to code this).

    On a side note: it might be a good idea to have a config entry in
the config file to add a user file where he could define his functions
without modifying functions.py . For large project it could prove
usefull.

I *haven't* yet added the target path to the standard namespace. I will 
do this very soon.

I have however made the namespace (and the 'uservalues') accessible to 
the functions (both as dictionaries).

Hmm... I'll think about the best way of doing this. Currently you can 
import whatever you want at the start of the templates, but maybe a way 
to specify a list of modules to automatically import would be good too.
