Well I solved the problem by writing a tangler which can be configured
with tangle-config
you define a tangler by making a hash "language" -> tangle-hooks. The
tangle-hooks are
called at beginning of tangling, on each source block, on each
noweb-ref and at the end of
tangling. They receive the full source-block-info to do their work,
and in the case of noweb-references
they receive the full stack of sbi's that lead up to this noweb reference.
>>>
(tangled-buffer "Buffer that is being tangled")
(name "Name of the code block")
(tangle-file "Filename to tangle to")
(properties "Properties of this block")
(full-block "Text of the full block")
(beg-block "Buffer pos of beginning of the block in the tangled buffer")
(end-block "end of the block in the tangled buffer")
(lang "language of the tangled buffer")
(beg-lang "beginning of the language in the tangled buffer")
(end-lang "end of the language in the tangled buffer")
(switches "switches of this block")
(beg-switches "begin of the switches in this block")
(end-switches "end of the switches in this block")
(header-args "header args of this block")
(beg-header-args "buffer pos of header args beginning")
(end-header-args "buffer pos of header args end")
(body "body of the tangled block")
(beg-body "buffer pos of the beginning of the body")
(end-body "buffer pos of the end of the body"))
>>>
That way I can tangle a multi language org file and do the correct thing for
each of the language by defining functions of interest. It's quite
flexible, I'm
going to use it to do some aspect-oriented programming/tangling when I
find the time.
