Re: [NTG-context] Current source directory.
Hi André,
Hans is right, it's a version problem.
You're using 2012.05.30 11:26 (from May)
I'm using 2012.09.25 21:44.
resolvers.inputstack is defined in my tex-data.lua.
I looked up your version among the commits on
http://repo.or.cz/w/context.git/shortlog,
and found that resolvers.inputstack is not yet defined in your data-tex.lua.
http://repo.or.cz/w/context.git/blob/ad5540007a2ac6504a47289ace109a76ec759a7e:/tex/context/base/data-tex.lua
So, you'll need to update I think. Which is a bit more work than usual
because minimals.contextgarden.net is down, but Johan Sandblom's
explains quite nicely what to do.

is it defined in yours? file-res.lua?
Thank you very very much, :-)

Re: [NTG-context] Current source directory.
Dear Sietse,
Thanks a lot!!!
Finally found it, after lots of trial-and-erroring through
likely-looking table names in file-job.lua: the stack of input files
is kept in resolvers.inputstack.
I don't program any lua. But I was taking a look at file-job.lua
myself. I have a lot to learn!! :-)
Assuming (absolute path of invocation
dir) + (path of file relative to invocation dir) = the desired path,
I don't mind this assumption.
Actually, I don't mind having a path relative to the currdir.
the following should work.
\cldcontext{
environment.runpath .. '/' ..
file.pathpart(resolvers.inputstack[#resolvers.inputstack])
}
I will try this now.
You may or may not want to parse out any ./ and ../ components.
No, I don't need that.
(If you do: helpful filename manipulation functions (such as
file.pathpart, indeed) may be found in l-file.lua.)
Thanks for the tip. Might be useful someday.
Hope this helps,
It does! :-)
Although, I think there should be a luatex command for this. That
is, something not related to ConTeXt.
Thank you,
André Caldas.

Hi!
the following should work.
\cldcontext{
environment.runpath .. '/' ..
file.pathpart(resolvers.inputstack[#resolvers.inputstack])
}
Sorry, to ask such a dumb question...
- Do I need to include file-job.lua somehow?

Hi André,

No need to include it, it's part of the ConTeXt core.
I only mentioned the filename in case people wanted to see what else
was in that file; the code snippet should Just Work. Is it working for
you?

Re: [NTG-context] Current source directory.
Hi André,
My mistake: I tested the code I gave you in \startluacode, but then
for the e-mail I wrapped it in \cldcontext. This is not the same: in
\startluacode # has its literal value, but in \cldcontext it is
interpreted as part of a macro parameter like #1.
So to get the length of a table t inside \cldcontext, I should have
used the idiom table.getn(t) instead of #t.
These two versions both work, and I actually tested them this time:
\startluacode
context(environment.runpath .. '/' ..
file.pathpart(resolvers.inputstack[#resolvers.inputstack])
)
\stopluacode
\cldcontext{
environment.runpath .. '/' ..
file.pathpart(resolvers.inputstack[table.getn(resolvers.inputstack)])
}
Sorry about that mistake.
Cheers,
Sietse

Re: [NTG-context] Current source directory.
Thank you for yor time, Peter. But this is not what I wanted... :-(
Is there a way to know the directory of the currently being processed
source file?
This works with mkiv:
\starttext
PWD: \cldcontext{io.popenpwd:read()}
\stoptext
This gives the directory where the context command was called from.
I want the directory where the tex file being processed lives in.
For example, I have a component
products/product/article.tex
Inside a product
products/product.tex
I produce it by calling
context products/product.tex
I want to know a function that returns
/fullpath_to_project/products/
when I call it from the script products/product.tex. And I want it to return
/fullpath_to_project/products/product/
when I call it from the script products/product/article.tex.
Cheers,
André Caldas.
