[INPUT-FILE] - -If a long option shows an argument as mandatory, then it is mandatory -for the equivalent short option also. - -Input file interpretation: - -e, --delimiters=DELIMITER-LIST - Allow user to provide a string containing delimiters - used to separate keywords from their attributes. - Default is ",\n". - -t, --struct-type Allows the user to include a structured type - declaration for generated code. Any text before %% - is considered part of the type declaration. Key - words and additional fields may follow this, one - group of fields per line. - -Language for the output code: - -L, --language=LANGUAGE-NAME - Generates code in the specified language. Languages - handled are currently C++, ANSI-C, C, and KR-C. The - default is C. - -Details in the output code: - -K, --slot-name=NAME Select name of the keyword component in the keyword - structure. - -H, --hash-fn-name=NAME - Specify name of generated hash function. Default is - `hash'. - -N, --lookup-fn-name=NAME - Specify name of generated lookup function. Default - name is `in_word_set'. - -Z, --class-name=NAME Specify name of generated C++ class. Default name is - `Perfect_Hash'. - -7, --seven-bit Assume 7-bit characters. - -c, --compare-strncmp Generate comparison code using strncmp rather than - strcmp. - -C, --readonly-tables Make the contents of generated lookup tables - constant, i.e., readonly. - -E, --enum Define constant values using an enum local to the - lookup function rather than with defines. - -I, --includes Include the necessary system include file <string.h> - at the beginning of the code. - -G, --global 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). - -W, --word-array-name=NAME - Specify name of word list array. Default name is - `wordlist'. - -S, --switch=COUNT 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 COUNT argument - 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. If COUNT is very - large, say 1000000, the generated C code does a - binary search. - -T, --omit-struct-type - Prevents the transfer of the type declaration to the - output file. Use this option if the type is already - defined elsewhere. - -Algorithm employed by gperf: - -k, --key-positions=KEYS - Select 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. - -l, --compare-strlen Compare key lengths before trying a string - comparison. This helps cut down on the number of - string comparisons made during the lookup. - -D, --duplicates Handle keywords that hash to duplicate values. This - is useful for certain highly redundant keyword sets. - -f, --fast=ITERATIONS 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''. - -i, --initial-asso=N 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, --jump=JUMP-VALUE Affects the ``jump value'', i.e., how far to advance - the associated character value upon collisions. Must - be an odd number, default is 5. - -n, --no-strlen Do not include the length of the keyword when - computing the hash function. - -o, --occurrence-sort Reorders input keys by frequency of occurrence of - the key sets. This should decrease the search time - dramatically. - -r, --random Utilizes randomness to initialize the associated - values table. - -s, --size-multiple=N Affects the size of the generated hash table. The - numeric argument N 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. - -Informative output: - -h, --help Print this message. - -v, --version Print the gperf version number. - -d, --debug Enables the debugging option (produces verbose - output to the standard error). - -Report bugs to <bug-gnu-utils@gnu.org>. |
