Hi all,
Thanks for the good information and ideas being shared here. Our
combined efforts will surely help us to further improve WSJT-X and the
other WSJT-related programs, to make them easier to maintain and
distribute on multiple platforms, and to facilitate more widespread
participation in their development.
Several things on my mind today:
*To Do List* - Here's an item to add to the list I posted a few days ago.
How best should we manage code used in more than one of our programs?
For example, I note that the following Fortran routines are common to
both WSJT and WSPR: azdist.f90, conv232.f90, db.f90, deg2grid.f90,
fano232.f90, four2a.f90, gencwid.f90, geodist.f90, getfile.f90,
grid2deg.f90, morse.f90, nchar.f90, packcall.f90, packgrid.f90,
packpfx.f90, pctile.f90, peakup.f90, set.f90, slope.f90, sort.f90,
ssort.f90, thnix.f90, thnix_stub.f90, unpackcall.f90, unpackgrid.f90,
unpackpfx.f90, xfft.f90. Many of these are used in WSJT-X, MAP65, and
WSPR-X as well.
At present, we have multiple copies of these routines in the different
SVN branches, and they're not necessarily identical. They probably
should be, and it could help a lot if they were stored and maintained in
one place only.
What is best practice in such a situation? Should we have an SVN branch
or branches called "common" or "libxyz" or some such, and build these
functions into libraries that can be linked by the several programs? We
would need to be aware that changes to things like calling sequences
might then require corresponding changes in more than one program.
Therefore, functions to be moved into such libraries should be ones that
have been stable for some time, and judged likely to remain so.
I realize that (especially for code like that summarized above) I'm
probably the one best suited to do this work. But I would value any
organizational suggestions on how best to arrange our source-code tree.
*Build Methods* - I think we're now committed to using CMake for
production builds of WSJT-X. CMake build tools are now in place for
MAP65 and WSPR, as well, although the scripts in place now are less
sophisticated than the one for WSJT-X. Some effort is needed here, and
CMakeLists.txt files for WSJT and WSPR could also be written.
*Trivia* - Does anyone here have some graphics skills? Our icons need
work. Somehow the ones in window title-bars look fuzzy compared with
wsjt.ico, the one we had been using; and I notice the icon for WSJT-X in
the Windows taskbar has become an unrelated system default. Can we
restore the use of the green-on-blue world globe for this purpose, and
perhaps tweak the picture so that it works well on all our supported
platforms?
