Finding-by-name
Functions for looking up and reordering parsed objects by their
names.
These are low-level functions that allow you to find parsed
objects (e.g., variables, modules, parameters) by their names, or to use names
to rearrange lists of objects.
Note: these functions do not have any proper understanding of
scoping issues. If you just want to look up a name and see what it refers to,
you should not use these functions; see scopestack instead.
One way to do find elements by name is to naively scan through the list of
items and retrieve the first one that matches the name. Our simple lookup
functions just do this for various types of objects. For instance, we provide
functions to "find a portdecl with the following name in this list of
portdecls."
If many items are going to be looked up from the same list, as is often the
case, then a faster approach is to construct a fast alist that maps the item
names to the items themselves, and then use hons-get to do hash table
lookups. See fast-finding-by-name for functions related to constructing
fast alists binding names to items that can be used for this purpose.
