This is useful + for certain highly redundant keyword sets. It enables the -S option. +-e Allow user to provide a string containing delimiters used to separate + keywords from their attributes. Default is ",\n" +-E Define constant values using an enum local to the lookup function + rather than with defines +-f Generate the gen-perf.hash function ``fast.'' This decreases GPERF's + running time at the cost of minimizing generated table-size. + The numeric argument represents the number of times to iterate when + resolving a collision. `0' means ``iterate by the number of keywords.'' +-g Assume a GNU compiler, e.g., g++ or gcc. This makes all generated + routines use the ``inline'' keyword to remove cost of function calls. +-G Generate the static table of keywords as a static global variable, + rather than hiding it inside of the lookup function (which is the + default behavior). +-h Prints this mesage. +-H Allow user to specify name of generated hash function. Default + is `hash'. +-i Provide an initial value for the associate values array. Default is 0. + Setting this value larger helps inflate the size of the final table. +-j Affects the ``jump value,'' i.e., how far to advance the associated + character value upon collisions. Must be an odd number, default is 5. +-k Allows selection of the key positions used in the hash function. + The allowable choices range between 1-126, inclusive. The positions + are separated by commas, ranges may be used, and key positions may + occur in any order. Also, the meta-character '*' causes the generated + hash function to consider ALL key positions, and $ indicates the + ``final character'' of a key, e.g., $,1,2,4,6-10. +-K Allow use to select name of the keyword component in the keyword structure. +-l Compare key lengths before trying a string comparison. This helps + cut down on the number of string comparisons made during the lookup. +-L Generates code in the language specified by the option's argument. Languages + handled are currently C++ and C. The default is C. +-n Do not include the length of the keyword when computing the hash function +-N Allow user to specify name of generated lookup function. Default + name is `in_word_set.' +-o Reorders input keys by frequency of occurrence of the key sets. + This should decrease the search time dramatically. +-p Changes the return value of the generated function ``in_word_set'' + from its default boolean value (i.e., 0 or 1), to type ``pointer + to wordlist array'' This is most useful when the -t option, allowing + user-defined structs, is used. +-r Utilizes randomness to initialize the associated values table. +-s Affects the size of the generated hash table. The numeric argument + for this option indicates ``how many times larger or smaller'' the associated + value range should be, in relationship to the number of keys, e.g. a value of 3 + means ``allow the maximum associated value to be about 3 times larger than the + number of input keys.'' Conversely, a value of -3 means ``make the maximum + associated value about 3 times smaller than the number of input keys. + A larger table should decrease the time required for an unsuccessful search, + at the expense of extra table space. Default value is 1. +-S Causes the generated C code to use a switch statement scheme, rather + than an array lookup table. This can lead to a reduction in both + time and space requirements for some keyfiles. The argument to + this option determines how many switch statements are generated. + A value of 1 generates 1 switch containing all the elements, a value of 2 + generates 2 tables with 1/2 the elements in each table, etc. This + is useful since many C compilers cannot correctly generate code for + large switch statements. +-t Allows the user to include a structured type declaration for + generated code. Any text before %% is consider part of the type + declaration. Key words and additional fields may follow this, one + group of fields per line. +-T Prevents the transfer of the type declaration to the output file. + Use this option if the type is already defined elsewhere. +-v Prints out the current version number +-Z Allow user to specify name of generated C++ class. Default + name is `Perfect_Hash.' +Usage: ../src/gperf [-acCdDef[num]gGhH<hashname>i<init>jk<keys>K<keyname>lL<language>nN<function name>oprs<size>S<switches>tTvZ<class name>]. +(type ../src/gperf -h for help) |
