[SynopticUseOptions::] Use Options.
|
|
|
|
To compile the main/synoptic/use_options submodule.
|
|
|
|
@ Our inventory |inv| already contains a list |inv->use_option_nodes| of all packages
|
|
in the tree with type |_use_option|.
|
|
|
|
=
|
|
void SynopticUseOptions::compile(inter_tree *I, pipeline_step *step, tree_inventory *inv) {

|
|
@<Define NO_USE_OPTIONS@>;
|
|
@<Define TESTUSEOPTION function@>;
|
|
@<Define PRINT_USE_OPTION function@>;
|
|
@<Define USE_OPTION_VALUES array@>;
|
|
}
|
|
|
|
@ Each use option package contains a numeric constant with the symbol name
|
|
|use_option_id|. We want to ensure that these ID numbers are contiguous from 0
|
|
and never duplicated, so we change the values of these constants accordingly.
|
|
|
|
@<Assign unique use option ID numbers@> =
|
|
InterNodeList::array_sort(inv->use_option_nodes, MakeSynopticModuleStage::module_order);

|
|
|
|
@ A relatively late addition to the design of use options was to make them
|
|
values at runtime, of the kind "use option". We need to provide two functions:
|
|
one to test whether a given use option is currently set, one to print the
|
|
name of a given use option.
