I’ve been working on the prototype implementation to get it building in
both Windows & Linux, using CMake & the Conan package manager:

   1. All unit tests complete successfully for both MSVC & gcc10
   2. All bgl17 code has been removed from the repository. It uses a cloned
   bgl17 directory (ENABLE_BGL17 cmake option).
   3. Catch2 is now being used instead of Google Test for unit testing
   4. A simple unit test demonstrates the use of the library’s
   *dfs_vertex_range* iteration *using bgl17’s vov graph*. This can be seen
   in test/test_vov_adaptor.cpp.
      1. There were a few changes needed in bgl17 to accommodate this (I
      haven’t pushed these changes)

                                                               i. I
added an inner_container type definition to vov

                                                             ii. There
were 3 places where I added #ifdef _*MSC*_VER to disable linux-specific
code, far fewer than before.

   1. Adapting vov requires the following

                                                               i. An
adaptor graph class to map the vov types to expected types

                                                             ii. Function
overloads that uses the adaptor graph class as a template argument

   1. Added graph API functions to avoid name ambiguity with begin(g) &
   end(g) for vertices in the dfs & bfs range iterators.
      1. vertex_begin(g), vertex_end(g)
      2. edge_begin(g,u), edge_end(g,u)



I haven’t written the code to support value(uv) function to get edge
properties for vov yet.

These changes should bring the library much closer to a repeatable
cross-platform build and you’re welcome to try it.

I’ve pushed the code to the master branch at https://github.com/pratzl/graph



The next SG19 meeting is 6/11/20 (12d from now) and I have some things in
mind to work on. I’ve been focused on the prototype to make it more
accessible for all the authors and I need to switch back to the paper and
give it more attention.

   1. Paper
      1. Complete algorithm descriptions & examples:

                                                               i.
Connected
Components

                                                             ii. Strongly
Connected components

                                                           iii.
Bi-connected
Components

                                                           iv.
Articulation
Points

   1. Data structures

                                                               i. Add
section on graph adaptors

   1. algorithm implementations
      1. connected & strongly connected components unit tests
      2. [bi-connected components]
      3. [articulation points]
   2. bgl17 adaptors
      1. vov adaptor: implement value(edge), add dfs_edge_range tests
      2. implement a compressed adaptor
   3. other prototype features
      1. Support Clang10 using the range-v3 concepts macros
   4. Documentation
      1. Add explicit description of how to install and use the library
