|
|
GNU gperf is a perfect hash function generator. For a given
|
|
list of strings, it produces a hash function and hash table, in
|
|
form of C or C++ code, for looking up a value depending on the
|
|
input string. The hash function is perfect, which means that
|
|
the hash table has no collisions, and the hash table lookup
|
|
needs a single string comparison only.
|
|
|
|
GNU gperf is highly customizable. There are options for
|
|
generating C or C++ code, for emitting switch statements or
|
|
nested ifs instead of a hash table, and for tuning the algorithm
|
|
employed by gperf.
