Vim syntax highlighting for Fortran OpenMP comments

There was a very useful answer on how to highlight openmp directives in Fortran code (Vim syntax highlighting for multiline fortran openmp directives). So lines like 

!$omp parallel

are no longer highlighted as comments.

It would be great also to make vim not to treat as comments lines starting with "!$", i.e. in constructs like

! Make it compile both with and without OMP
nThreads = 1
!$ nThreads = omp_get_num_threads()

I want to have !$ highlighted as fortrandirective, and the rest of the last line highlighted normally.

Solution

  • You could use syn match for this: 

    :syn match fortranDirective "\v!\$\s"

    This matches !$ with a trailing whitespace (to distinguish it from !$omp).
