    33Misplaced or mis-spelt variables in configuration namelist files can be a source of frustration when porting configurations used with older releases of NEMO to more modern versions. The code will report these occurrences and stop during start-up; but only one instance is reported each time. Finding them all this way can be a time-consuming business. Part 1 of this page details a simple Python script which can be used to find mis-matches between a configuration namelist and its reference counterpart before attempting to run the model.

    5 For most users, this should be sufficient but developers of new features have the added uncertainty of not knowing if the reference namelist correctly contains all the namlist options available in the code. Part 2 of this page suggests further tools which can can construct a 'pseudo reference namelist' by parsing the fortran code base. The actual reference namelist and the 'pseudo' version can then be used with the integrity checker from part 1. By using the integrity checker twice, with the roles of the two namelists swapped, it is possible to confirm that:

    159 It is probably the case that the structure variables flagged (sn_*) are false positives. This is because only the structure name is declared in the namelist but individual members of the structure may be (and are) set the ''namelist_ref''. Nonetheless, there are quite a few normal variables to investigate. Even if these issues are resolved in more up-to-date revisions, this does illustrate the potential usefulness of this tool.
