Branch dev_r11615_ENHANCE-04_namelists_as_internalfiles_agrif. Changes to support 2019/dev_r11615_ENHANCE-04_namelists_as_internalfiles developments.
These changes enable sufficient support for allocatable, zero-dimension character variables defined using the:

CHARACTER(LEN=:), ALLOCATABLE :: cstr

syntax. This is supported by:

  1. Adding : as a valid length identifier at line 1028 in fortran.y (and then rebuilding fortran.c and main.c via make -f Makefile.lex)
  2. Adding a carrayu entry to Agrif_Variable_c type in AGRIF_FILES/modtypes.F90 where carrayu is declared as:
character(:) , allocatable
carrayu
Ensuring correct deallocation of carrayu in AGRIF_FILES/modsauv.F90 and AGRIF_FILES/modutil.F90
  • Substituting carrayu in place of carray0 declarations when character length matches : for zero-dimension variables. This occurs twice in LIB/toamr.c, e.g:

    • if (!strcasecmp(var->v_dimchar ,":") && var->v_nbdim == 0 )
    {
    sprintf (tname_2, "%% carrayu");
    } else {
    sprintf (tname_2, "%% carray%d", var->v_nbdim);
    }

    Any such character variables must be allocated by the user. Typically this is done with lines such as:

    IF ( .NOT. ALLOCATED(cdnambuff) ) ALLOCATE( CHARACTER(LEN=kleng)
    cdnambuff )

    making AGRIF accept the CHARACTER(LEN=kleng) :: construct within the ALLOCATE statement was beyond my skills. Fortunately, for the current purpose, this
    isn't necessary since such allocations only occur within utility routines in which the appropriate tabvar has been passed down. So:

    !$AGRIF_DO_NOT_TREAT

    IF ( .NOT. ALLOCATED(cdnambuff) ) ALLOCATE( CHARACTER(LEN=kleng)
    cdnambuff )
    !$AGRIF_END_DO_NOT_TREAT

    avoids the issue.
