An even easier solution (as proposed by Bill Hoffman) is for CMake to parse
fortran files ignoring all distinctions between fixed and free format (so
that any line starting with [cC*dD] is automatically skipped even though it
is not a comment for the free format). That solution appeals to me (I like
simplicity), but I am a little uneasy with it because it might cause trouble
now (jury is still out on that because nobody has listed what kinds of
things CMake is currently trying to parse in the fortran file), and if CMake
expanded the list of what was parsed in the future, it might cause obscure
bugs down the road where key free-form lines are skipped because they are
incorrectly interpreted as comments. For that reason I prefer the definite
FORTRAN_FIXED_FORM scheme where it is difficult to go wrong unless the
developer is unaware of what fortran form he is dealing with (in which case
he will probably have non-CMake problems as well).
I am for easy, and having to specify this is difficult for cmake developers and
for cmake users. The only thing cmake is parsing the files for is to create
depend information, that is it. I have not yet seen a case where the cC*dD
starting a
line would cause incorrect depend information and still be valid fortran code.
OK. That statement about the limited nature of the parsing is reassuring so
would somebody please commit the solution, i.e.,
<fixed_fmt>^[cC*dD].*\n { return EOSTMT; }
to:
^[cC*dD].*\n { return EOSTMT; }
that Bryan Walsh has already worked out?
