#143: Reorganize milena/mln/core/ ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: task | Status: new Priority: minor | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- (This ticket is just a proposal. We might close it even if no change occur in `milena/mln/core`.) There are many things in source:trunk/milena/mln/core/, that could be reorganized and/or split in several directories/subdirectories: * basic/classic images and entites (`mln::image2d`, etc.) * graph-based images and entities (`mln::graph_image`, etc.) * non classic images and associated tools (`mln::rle_image`, etc.) * morphers (`mln::cast_image`, etc.) * internal/core mechanisms (`initialize.hh` etc.) * general tools (`contract.hh`, `inplace.hh`, etc.) * concepts (though they are located in their own directory, `mln/core/concept/`) * implementation/factoring classes (thought most of them are in `mln/core/internal/`) * other entities, that should be moved elsewhere (`mln::h_vec`, etc.) * and so on. To my (Roland) mind, we should: 1. Identify the different kind of files present in `core/`. 2. Assign one (maybe two) kinds to each file of this directory. 3. Determine a new file layout, and perform the moves. -- Ticket URL: <https://trac.lrde.org/olena/ticket/143> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

Note: this can be solved with iterators where the dimension can be either static or dynamic. Let's start with a dynamic one, as it would allow us to write something like this: mln_fwd_citer_(topo::complex<D>) f(c); mln_fwd_lower_nciter(topo::complex<D>) n(c); for_all(c) for_all(n) // ... (Note: we might want to get rid of the name `citer', and use `fiter' everywhere.). A static version might be useful (and more efficient) too. Likewise, our iterators on n-faces (both faces_piter and complex_faces_piter) use a static `n'. We should also have n-faces iterators where n could be dynamic. But first, we need to clarify (existing) names. ----------------------------------------------------------------- Current name New name Definition ----------------------------------------------------------------- complex<D> (n/a) General complex face<N, D> face_data<N, D> Face data face_handle<N, D> n_face<N, D> (Static) n-face handle faces_set<N, D> n_faces_set<N, D> Set of face handles any_face_handle<D> face<D> Dynamic face handle complex_fwd_iter_<D>(c) face_fwd_iter<D>(c) | Iterators on all complex_bkd_iter_<D>(c) face_bkd_iter<D>(c) | faces of c complex_iter_base_<F, E> complex_iter_base<F, E> | Factoring base | class. ----------------------------------------------------------------- (Note: get rid of trailing underscores, even for entities in mln::internal::.)

#159: Distribute SWIG wrappers -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: minor | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- According to Alexandre Hamez, files generated by `swig` (e.g., `*.py` and `*-wrap.cc`) are portable. We should distribute them, as * it would save users wanting to use Swilena some time; * it would free them to have SWIG to compile Swilena. To do: * distribute these files (remove `nodist_` prefixes); * ensure they're available at distribution time (use `dist-hook` in `Makefile.am`); * add generated files to `MAINTAINERCLEANFILES`; * adjust `configure.ac`?
