15.1.2 Disable Metrics For Local Units

gnatmetric relies on the GNAT compilation model − one compilation unit per one source file. It computes line metrics for the whole source file, and it also computes syntax and complexity metrics for the file's outermost unit.

By default, gnatmetric will also compute all metrics for certain kinds of locally declared program units:

These kinds of entities will be referred to as eligible local program units, or simply eligible local units, in the discussion below.

Note that a subprogram declaration, generic instantiation, or renaming declaration only receives metrics computation when it appear as the outermost entity in a source file.

Suppression of metrics computation for eligible local units can be obtained via the following switch:

Do not compute detailed metrics for eligible local program units
