Description

fpm doesn't classify correctly the source type of program units without a program-statement, such as:

print *, "Hello World"
end

or

print *, "Hello World"
end program

which are allowed according to the standard.

Currently, parse_f_source will return FPM_UNIT_SUBPROGRAM (=4)` for these two cases.

Expected Behaviour

The expected source unit type should be FPM_UNIT_PROGRAM (=1).

Version of fpm

0.8.1, alpha

Platform and Architecture

MacOS (Intel)

Additional Information

The culprit is the parsing logic, which relies on detecting the program statement at front:

Instead it should probably rely on the end program statement which is mandatory per the standard. (J3/24-007, 14.1)
