Overriding lxr.conf Parameters on a Per-tree Basis

As mentioned in another page, the configuration file is read in two passes:

• The first pass considers only the zeroth parameter group

  These parameters are entered in a dictionary.

• The second pass selects one parameter group among the remaining

  The parameters from the selected group update the dictionary. If a key duplicates one from the zeroth group, its value replaces the previous one.

You can take advantage of these two passes by writing parameters applicable to almost all trees in the zeroth parameter group. The value needed by the other trees is just repeated in the relevant tree specific parameter groups.
