It uses -those values to create a `Makefile' in each directory of the package. -It may also create one or more `.h' files containing system-dependent -definitions. Finally, it creates a shell script `config.status' that -you can run in the future to recreate the current configuration, a file -`config.cache' that saves the results of its tests to speed up -reconfiguring, and a file `config.log' containing compiler output -(useful mainly for debugging `configure'). - - If you need to do unusual things to compile the package, please try -to figure out how `configure' could check whether to do them, and mail -diffs or instructions to the address given in the `README' so they can -be considered for the next release. If at some point `config.cache' -contains results you don't want to keep, you may remove or edit it. - - The file `configure.in' is used to create `configure' by a program -called `autoconf'. You only need `configure.in' if you want to change -it or regenerate `configure' using a newer version of `autoconf'. - -The simplest way to compile this package is: - - 1. `cd' to the directory containing the package's source code and type - `./configure' to configure the package for your system. If you're - using `csh' on an old version of System V, you might need to type - `sh ./configure' instead to prevent `csh' from trying to execute - `configure' itself. - - Running `configure' takes a while. While running, it prints some - messages telling which features it is checking for. - - 2. Type `make' to compile the package. - - 3. Optionally, type `make check' to run any self-tests that come with - the package. - - 4. Type `make install' to install the programs and any data files and - documentation. - - 5. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - -Compilers and Options -===================== - - Some systems require unusual options for compilation or linking that -the `configure' script does not know about. You can give `configure' -initial values for variables by setting them in the environment. Using -a Bourne-compatible shell, you can do that on the command line like -this: - CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure - -Or on systems that have the `env' program, you can do it like this: - env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure - -Compiling For Multiple Architectures -==================================== - - You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you must use a version of `make' that -supports the `VPATH' variable, such as GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. - - If you have to use a `make' that does not supports the `VPATH' -variable, you have to compile the package for one architecture at a time -in the source code directory. After you have installed the package for -one architecture, use `make distclean' before reconfiguring for another -architecture. - -Installation Names -================== - - By default, `make install' will install the package's files in -`/usr/local/bin', `/usr/local/man', etc. You can specify an -installation prefix other than `/usr/local' by giving `configure' the -option `--prefix=PATH'. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -give `configure' the option `--exec-prefix=PATH', the package will use -PATH as the prefix for installing programs and libraries. -Documentation and other data files will still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=PATH' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - -Optional Features -================= - - Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - -Specifying the System Type -========================== - - There may be some features `configure' can not figure out -automatically, but needs to determine by the type of host the package -will run on. Usually `configure' can figure that out, but if it prints -a message saying it can not guess the host type, give it the -`--host=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name with three fields: - CPU-COMPANY-SYSTEM - -See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the host type. - - If you are building compiler tools for cross-compiling, you can also -use the `--target=TYPE' option to select the type of system they will -produce code for and the `--build=TYPE' option to select the type of -system on which you are compiling the package. - -Sharing Defaults -================ - - If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Operation Controls -================== - - `configure' recognizes the following options to control how it -operates. - -`--cache-file=FILE' - Use and save the results of the tests in FILE instead of - `./config.cache'. Set FILE to `/dev/null' to disable caching, for - debugging `configure'. - -`--help' - Print a summary of the options to `configure', and exit. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`--version' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`configure' also accepts some other, not widely useful, options. - diff --git a/contrib/gperf/Makefile.devel b/contrib/gperf/Makefile.devel deleted file mode 100644 index cd6b6282acfe..000000000000 --- a/contrib/gperf/Makefile.devel +++ /dev/null @@ -1,38 +0,0 @@ -# This is the developer's makefile, not the user's makefile. -# Don't use it unless you know exactly what you do! - -SHELL = /bin/sh -MAKE = make - -all : configures src/config.h.in doc/gperf.1 - -CONFIGURES = configure lib/configure src/configure tests/configure doc/configure - -configures : $(CONFIGURES) - -configure : configure.in aclocal.m4 - autoconf -l . - -lib/configure : lib/configure.in aclocal.m4 - cd lib && autoconf -l .. - -src/configure : src/configure.in aclocal.m4 - cd src && autoconf -l .. - -tests/configure : tests/configure.in aclocal.m4 - cd tests && autoconf -l .. - -doc/configure : doc/configure.in aclocal.m4 - cd doc && autoconf -l .. - -check-configures : $(CONFIGURES) - set -e; for f in $(CONFIGURES); do bash -x -n $$f; done - -src/config.h.in : src/configure.in aclocal.m4 - cd src && autoheader -l .. - -doc/gperf.1 : force - prog=`PATH=build/src:src:$$PATH which gperf`; if test -n "$$prog"; then doc/help2man --name='generate a perfect hash function from a key set' --section=1 $$prog > doc/gperf.1; fi - -force : - diff --git a/contrib/gperf/Makefile.in b/contrib/gperf/Makefile.in deleted file mode 100644 index 1d9336afa8a9..000000000000 --- a/contrib/gperf/Makefile.in +++ /dev/null @@ -1,62 +0,0 @@ -# Makefile for gperf - -# Copyright (C) 1989, 1992, 1993, 1998 Free Software Foundation, Inc. -# written by Douglas C.

Default name is -`wordlist'. -.TP -\fB\-S\fR, \fB\-\-switch\fR=\fICOUNT\fR -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. -.TP -\fB\-T\fR, \fB\-\-omit\-struct\-type\fR -Prevents the transfer of the type declaration to the -output file.

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.''

The general -idea for the perfect hash function generator was inspired by Keith -Bostic's algorithm written in C, and distributed to net.sources around -1984.

It -transforms an @var{n} element user-specified keyword set @var{W} into a -perfect hash function @var{F}. @var{F} uniquely maps keywords in -@var{W} onto the range 0..@var{k}, where @var{k} >= @var{n}. If @var{k} -= @var{n} then @var{F} is a @emph{minimal} perfect hash function. -@code{gperf} generates a 0..@var{k} element static lookup table and a -pair of C functions. These functions determine whether a given -character string @var{s} occurs in @var{W}, using at most one probe into -the lookup table. - -@code{gperf} currently generates the reserved keyword recognizer for -lexical analyzers in several production and research compilers and -language processing tools, including GNU C, GNU C++, GNU Pascal, GNU -Modula 3, and GNU indent. Complete C++ source code for @code{gperf} is -available via anonymous ftp from @code{ftp://ftp.gnu.org/pub/gnu/gperf/}. -A paper describing @code{gperf}'s design and implementation in greater -detail is available in the Second USENIX C++ Conference proceedings. - -@node Search Structures, Description, Motivation, Top -@chapter Static search structures and GNU @code{gperf} -@cindex Static search structure - -A @dfn{static search structure} is an Abstract Data Type with certain -fundamental operations, e.g., @emph{initialize}, @emph{insert}, -and @emph{retrieve}. Conceptually, all insertions occur before any -retrievals. In practice, @code{gperf} generates a @code{static} array -containing search set keywords and any associated attributes specified -by the user. Thus, there is essentially no execution-time cost for the -insertions. It is a useful data structure for representing @emph{static -search sets}. Static search sets occur frequently in software system -applications. Typical static search sets include compiler reserved -words, assembler instruction opcodes, and built-in shell interpreter -commands. Search set members, called @dfn{keywords}, are inserted into -the structure only once, usually during program initialization, and are -not generally modified at run-time. - -Numerous static search structure implementations exist, e.g., -arrays, linked lists, binary search trees, digital search tries, and -hash tables. Different approaches offer trade-offs between space -utilization and search time efficiency. For example, an @var{n} element -sorted array is space efficient, though the average-case time -complexity for retrieval operations using binary search is -proportional to log @var{n}. Conversely, hash table implementations -often locate a table entry in constant time, but typically impose -additional memory overhead and exhibit poor worst case performance. - -@cindex Minimal perfect hash functions -@emph{Minimal perfect hash functions} provide an optimal solution for a -particular class of static search sets. A minimal perfect hash -function is defined by two properties: - -@itemize @bullet -@item -It allows keyword recognition in a static search set using at most -@emph{one} probe into the hash table. This represents the ``perfect'' -property. -@item -The actual memory allocated to store the keywords is precisely large -enough for the keyword set, and @emph{no larger}. This is the -``minimal'' property. -@end itemize - -For most applications it is far easier to generate @emph{perfect} hash -functions than @emph{minimal perfect} hash functions. Moreover, -non-minimal perfect hash functions frequently execute faster than -minimal ones in practice. This phenomena occurs since searching a -sparse keyword table increases the probability of locating a ``null'' -entry, thereby reducing string comparisons. @code{gperf}'s default -behavior generates @emph{near-minimal} perfect hash functions for -keyword sets. However, @code{gperf} provides many options that permit -user control over the degree of minimality and perfection. - -Static search sets often exhibit relative stability over time. For -example, Ada's 63 reserved words have remained constant for nearly a -decade. It is therefore frequently worthwhile to expend concerted -effort building an optimal search structure @emph{once}, if it -subsequently receives heavy use multiple times. @code{gperf} removes -the drudgery associated with constructing time- and space-efficient -search structures by hand. It has proven a useful and practical tool -for serious programming projects. Output from @code{gperf} is currently -used in several production and research compilers, including GNU C, GNU -C++, GNU Pascal, and GNU Modula 3. The latter two compilers are not yet -part of the official GNU distribution. Each compiler utilizes -@code{gperf} to automatically generate static search structures that -efficiently identify their respective reserved keywords. - -@node Description, Options, Search Structures, Top -@chapter High-Level Description of GNU @code{gperf} - -@menu -* Input Format:: Input Format to @code{gperf} -* Output Format:: Output Format for Generated C Code with @code{gperf} -* Binary Strings:: Use of NUL characters -@end menu - -The perfect hash function generator @code{gperf} reads a set of -``keywords'' from a @dfn{keyfile} (or from the standard input by -default). It attempts to derive a perfect hashing function that -recognizes a member of the @dfn{static keyword set} with at most a -single probe into the lookup table. If @code{gperf} succeeds in -generating such a function it produces a pair of C source code routines -that perform hashing and table lookup recognition. All generated C code -is directed to the standard output. Command-line options described -below allow you to modify the input and output format to @code{gperf}. - -By default, @code{gperf} attempts to produce time-efficient code, with -less emphasis on efficient space utilization. However, several options -exist that permit trading-off execution time for storage space and vice -versa. In particular, expanding the generated table size produces a -sparse search structure, generally yielding faster searches. -Conversely, you can direct @code{gperf} to utilize a C @code{switch} -statement scheme that minimizes data space storage size. Furthermore, -using a C @code{switch} may actually speed up the keyword retrieval time -somewhat. Actual results depend on your C compiler, of course. - -In general, @code{gperf} assigns values to the characters it is using -for hashing until some set of values gives each keyword a unique value. -A helpful heuristic is that the larger the hash value range, the easier -it is for @code{gperf} to find and generate a perfect hash function. -Experimentation is the key to getting the most from @code{gperf}. - -@node Input Format, Output Format, Description, Description -@section Input Format to @code{gperf} -@cindex Format -@cindex Declaration section -@cindex Keywords section -@cindex Functions section -You can control the input keyfile format by varying certain command-line -arguments, in particular the @samp{-t} option. The input's appearance -is similar to GNU utilities @code{flex} and @code{bison} (or UNIX -utilities @code{lex} and @code{yacc}). Here's an outline of the general -format: - -@example -@group -declarations -%% -keywords -%% -functions -@end group -@end example - -@emph{Unlike} @code{flex} or @code{bison}, all sections of -@code{gperf}'s input are optional. The following sections describe the -input format for each section. - -@menu -* Declarations:: @code{struct} Declarations and C Code Inclusion. -* Keywords:: Format for Keyword Entries. -* Functions:: Including Additional C Functions. -@end menu - -@node Declarations, Keywords, Input Format, Input Format -@subsection @code{struct} Declarations and C Code Inclusion - -The keyword input file optionally contains a section for including -arbitrary C declarations and definitions, as well as provisions for -providing a user-supplied @code{struct}. If the @samp{-t} option -@emph{is} enabled, you @emph{must} provide a C @code{struct} as the last -component in the declaration section from the keyfile file. The first -field in this struct must be a @code{char *} or @code{const char *} -identifier called @samp{name}, although it is possible to modify this -field's name with the @samp{-K} option described below. - -Here is a simple example, using months of the year and their attributes as -input: - -@example -@group -struct months @{ char *name; int number; int days; int leap_days; @}; -%% -january, 1, 31, 31 -february, 2, 28, 29 -march, 3, 31, 31 -april, 4, 30, 30 -may, 5, 31, 31 -june, 6, 30, 30 -july, 7, 31, 31 -august, 8, 31, 31 -september, 9, 30, 30 -october, 10, 31, 31 -november, 11, 30, 30 -december, 12, 31, 31 -@end group -@end example - -@cindex @samp{%%} -Separating the @code{struct} declaration from the list of keywords and -other fields are a pair of consecutive percent signs, @samp{%%}, -appearing left justified in the first column, as in the UNIX utility -@code{lex}. - -@cindex @samp{%@{} -@cindex @samp{%@}} -Using a syntax similar to GNU utilities @code{flex} and @code{bison}, it -is possible to directly include C source text and comments verbatim into -the generated output file. This is accomplished by enclosing the region -inside left-justified surrounding @samp{%@{}, @samp{%@}} pairs. Here is -an input fragment based on the previous example that illustrates this -feature: - -@example -@group -%@{ -#include <assert.h> -/* This section of code is inserted directly into the output. */ -int return_month_days (struct months *months, int is_leap_year); -%@} -struct months @{ char *name; int number; int days; int leap_days; @}; -%% -january, 1, 31, 31 -february, 2, 28, 29 -march, 3, 31, 31 -... -@end group -@end example - -It is possible to omit the declaration section entirely. In this case -the keyfile begins directly with the first keyword line, e.g.: - -@example -@group -january, 1, 31, 31 -february, 2, 28, 29 -march, 3, 31, 31 -april, 4, 30, 30 -... -@end group -@end example - -@node Keywords, Functions, Declarations, Input Format -@subsection Format for Keyword Entries - -The second keyfile format section contains lines of keywords and any -associated attributes you might supply. A line beginning with @samp{#} -in the first column is considered a comment. Everything following the -@samp{#} is ignored, up to and including the following newline. - -The first field of each non-comment line is always the key itself. It -can be given in two ways: as a simple name, i.e., without surrounding -string quotation marks, or as a string enclosed in double-quotes, in -C syntax, possibly with backslash escapes like @code{\"} or @code{\234} -or @code{\xa8}. In either case, it must start right at the beginning -of the line, without leading whitespace. -In this context, a ``field'' is considered to extend up to, but -not include, the first blank, comma, or newline. Here is a simple -example taken from a partial list of C reserved words: - -@example -@group -# These are a few C reserved words, see the c.gperf file -# for a complete list of ANSI C reserved words. -unsigned -sizeof -switch -signed -if -default -for -while -return -@end group -@end example - -Note that unlike @code{flex} or @code{bison} the first @samp{%%} marker -may be elided if the declaration section is empty. - -Additional fields may optionally follow the leading keyword. Fields -should be separated by commas, and terminate at the end of line. What -these fields mean is entirely up to you; they are used to initialize the -elements of the user-defined @code{struct} provided by you in the -declaration section. If the @samp{-t} option is @emph{not} enabled -these fields are simply ignored. All previous examples except the last -one contain keyword attributes. - -@node Functions, , Keywords, Input Format -@subsection Including Additional C Functions - -The optional third section also corresponds closely with conventions -found in @code{flex} and @code{bison}. All text in this section, -starting at the final @samp{%%} and extending to the end of the input -file, is included verbatim into the generated output file. Naturally, -it is your responsibility to ensure that the code contained in this -section is valid C. - -@node Output Format, Binary Strings, Input Format, Description -@section Output Format for Generated C Code with @code{gperf} -@cindex hash table - -Several options control how the generated C code appears on the standard -output. Two C function are generated. They are called @code{hash} and -@code{in_word_set}, although you may modify their names with a command-line -option. Both functions require two arguments, a string, @code{char *} -@var{str}, and a length parameter, @code{int} @var{len}. Their default -function prototypes are as follows: - -@deftypefun {unsigned int} hash (const char * @var{str}, unsigned int @var{len}) -By default, the generated @code{hash} function returns an integer value -created by adding @var{len} to several user-specified @var{str} key -positions indexed into an @dfn{associated values} table stored in a -local static array. The associated values table is constructed -internally by @code{gperf} and later output as a static local C array -called @samp{hash_table}; its meaning and properties are described below -(@pxref{Implementation}). The relevant key positions are specified via -the @samp{-k} option when running @code{gperf}, as detailed in the -@emph{Options} section below(@pxref{Options}). -@end deftypefun - -@deftypefun {} in_word_set (const char * @var{str}, unsigned int @var{len}) -If @var{str} is in the keyword set, returns a pointer to that -keyword. More exactly, if the option @samp{-t} was given, it returns -a pointer to the matching keyword's structure. Otherwise it returns -@code{NULL}. -@end deftypefun - -If the option @samp{-c} is not used, @var{str} must be a NUL terminated -string of exactly length @var{len}. If @samp{-c} is used, @var{str} must -simply be an array of @var{len} characters and does not need to be NUL -terminated. - -The code generated for these two functions is affected by the following -options: - -@table @samp -@item -t -@itemx --struct-type -Make use of the user-defined @code{struct}. - -@item -S @var{total-switch-statements} -@itemx --switch=@var{total-switch-statements} -@cindex @code{switch} -Generate 1 or more C @code{switch} statement rather than use a large, -(and potentially sparse) static array. Although the exact time and -space savings of this approach vary according to your C compiler's -degree of optimization, this method often results in smaller and faster -code. -@end table - -If the @samp{-t} and @samp{-S} options are omitted, the default action -is to generate a @code{char *} array containing the keys, together with -additional null strings used for padding the array. By experimenting -with the various input and output options, and timing the resulting C -code, you can determine the best option choices for different keyword -set characteristics. - -@node Binary Strings, , Output Format, Description -@section Use of NUL characters -@cindex NUL - -By default, the code generated by @code{gperf} operates on zero -terminated strings, the usual representation of strings in C. This means -that the keywords in the input file must not contain NUL characters, -and the @var{str} argument passed to @code{hash} or @code{in_word_set} -must be NUL terminated and have exactly length @var{len}. - -If option @samp{-c} is used, then the @var{str} argument does not need -to be NUL terminated. The code generated by @code{gperf} will only -access the first @var{len}, not @var{len+1}, bytes starting at @var{str}. -However, the keywords in the input file still must not contain NUL -characters. - -If option @samp{-l} is used, then the hash table performs binary -comparison. The keywords in the input file may contain NUL characters, -written in string syntax as @code{\000} or @code{\x00}, and the code -generated by @code{gperf} will treat NUL like any other character. -Also, in this case the @samp{-c} option is ignored. - -@node Options, Bugs, Description, Top -@chapter Invoking @code{gperf} - -There are @emph{many} options to @code{gperf}. They were added to make -the program more convenient for use with real applications. ``On-line'' -help is readily available via the @samp{-h} option.

Furthermore, the meta-character '*' causes the generated -hash function to consider @strong{all} character positions in each key, -whereas '$' instructs the hash function to use the ``final character'' -of a key (this is the only way to use a character position greater than -126, incidentally). - -For instance, the option @samp{-k 1,2,4,6-10,'$'} generates a hash -function that considers positions 1,2,4,6,7,8,9,10, plus the last -character in each key (which may differ for each key, obviously).

This might cut -down on the number of string comparisons made during the lookup, since -keys with different lengths are never compared via @code{strcmp}. -However, using @samp{-l} might greatly increase the size of the -generated C code if the lookup table range is large (which implies that -the switch option @samp{-S} is not enabled), since the length table -contains as many elements as there are entries in the lookup table. -This option is mandatory for binary comparisons (@pxref{Binary Strings}). - -@item -D -@itemx --duplicates -@cindex Duplicates -Handle keywords whose key position sets hash to duplicate values. -Duplicate hash values occur for two reasons: - -@itemize @bullet -@item -Since @code{gperf} does not backtrack it is possible for it to process -all your input keywords without finding a unique mapping for each word. -However, frequently only a very small number of duplicates occur, and -the majority of keys still require one probe into the table. - -@item -Sometimes a set of keys may have the same names, but possess different -attributes. With the -D option @code{gperf} treats all these keys as -part of an equivalence class and generates a perfect hash function with -multiple comparisons for duplicate keys. It is up to you to completely -disambiguate the keywords by modifying the generated C code. However, -@code{gperf} helps you out by organizing the output. -@end itemize - -Option @samp{-D} is extremely useful for certain large or highly -redundant keyword sets, e.g., assembler instruction opcodes. -Using this option usually means that the generated hash function is no -longer perfect. On the other hand, it permits @code{gperf} to work on -keyword sets that it otherwise could not handle. - -@item -f @var{iteration-amount} -@itemx --fast=@var{iteration-amount} -Generate the perfect hash function ``fast''. This decreases -@code{gperf}'s running time at the cost of minimizing generated -table-size. The iteration amount represents the number of times to -iterate when resolving a collision. `0' means iterate by the number of -keywords. This option is probably most useful when used in conjunction -with options @samp{-D} and/or @samp{-S} for @emph{large} keyword sets. - -@item -i @var{initial-value} -@itemx --initial-asso=@var{initial-value} -Provides an initial @var{value} for the associate values array. Default -is 0. Increasing the initial value helps inflate the final table size, -possibly leading to more time efficient keyword lookups. Note that this -option is not particularly useful when @samp{-S} is used. Also, -@samp{-i} is overridden when the @samp{-r} option is used. - -@item -j @var{jump-value} -@itemx --jump=@var{jump-value} -@cindex Jump value -Affects the ``jump value'', i.e., how far to advance the associated -character value upon collisions. @var{Jump-value} is rounded up to an -odd number, the default is 5. If the @var{jump-value} is 0 @code{gperf} -jumps by random amounts. - -@item -n -@itemx --no-strlen -Instructs the generator not to include the length of a keyword when -computing its hash value. This may save a few assembly instructions in -the generated lookup table. - -@item -o -@itemx --occurrence-sort -Reorders the keywords by sorting the keywords so that frequently -occuring key position set components appear first. A second reordering -pass follows so that keys with ``already determined values'' are placed -towards the front of the keylist. This may decrease the time required -to generate a perfect hash function for many keyword sets, and also -produce more minimal perfect hash functions. The reason for this is -that the reordering helps prune the search time by handling inevitable -collisions early in the search process. On the other hand, if the -number of keywords is @emph{very} large using @samp{-o} may -@emph{increase} @code{gperf}'s execution time, since collisions will -begin earlier and continue throughout the remainder of keyword -processing. See Cichelli's paper from the January 1980 Communications -of the ACM for details. - -@item -r -@itemx --random -Utilizes randomness to initialize the associated values table. This -frequently generates solutions faster than using deterministic -initialization (which starts all associated values at 0). Furthermore, -using the randomization option generally increases the size of the -table. If @code{gperf} has difficultly with a certain keyword set try using -@samp{-r} or @samp{-D}. - -@item -s @var{size-multiple} -@itemx --size-multiple=@var{size-multiple} -Affects the size of the generated hash table. The numeric argument for -this option indicates ``how many times larger or smaller'' the maximum -associated value range should be, in relationship to the number of keys. -If the @var{size-multiple} is negative the maximum associated value is -calculated by @emph{dividing} it into the total number of keys. For -example, 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 ``allow the maximum associated value to -be about 3 times smaller than the number of input keys''. Negative -values are useful for limiting the overall size of the generated hash -table, though this usually increases the number of duplicate hash -values. - -If `generate switch' option @samp{-S} is @emph{not} enabled, the maximum -associated value influences the static array table size, and a larger -table should decrease the time required for an unsuccessful search, at -the expense of extra table space. - -The default value is 1, thus the default maximum associated value about -the same size as the number of keys (for efficiency, the maximum -associated value is always rounded up to a power of 2). The actual -table size may vary somewhat, since this technique is essentially a -heuristic. In particular, setting this value too high slows down -@code{gperf}'s runtime, since it must search through a much larger range -of values. Judicious use of the @samp{-f} option helps alleviate this -overhead, however. -@end table - -@node Verbosity, , Algorithmic Details, Options -@section Informative Output - -@table @samp -@item -h -@itemx --help -Prints a short summary on the meaning of each program option.

It is -extremely useful for maintaining perfect hash functions for compiler -keyword sets. Several recent enhancements now enable @code{gperf} to -work efficiently on much larger keyword sets (over 15,000 keywords). -When processing large keyword sets it helps greatly to have over 8 megs -of RAM. - -However, since @code{gperf} does not backtrack no guaranteed solution -occurs on every run. On the other hand, it is usually easy to obtain a -solution by varying the option parameters. In particular, try the -@samp{-r} option, and also try changing the default arguments to the -@samp{-s} and @samp{-j} options. To @emph{guarantee} a solution, use -the @samp{-D} and @samp{-S} options, although the final results are not -likely to be a @emph{perfect} hash function anymore! Finally, use the -@samp{-f} option if you want @code{gperf} to generate the perfect hash -function @emph{fast}, with less emphasis on making it minimal. - -@item -The size of the generate static keyword array can get @emph{extremely} -large if the input keyword file is large or if the keywords are quite -similar. This tends to slow down the compilation of the generated C -code, and @emph{greatly} inflates the object code size. If this -situation occurs, consider using the @samp{-S} option to reduce data -size, potentially increasing keyword recognition time a negligible -amount. Since many C compilers cannot correctly generated code for -large switch statements it is important to qualify the @var{-S} option -with an appropriate numerical argument that controls the number of -switch statements generated. - -@item -The maximum number of key positions selected for a given key has an -arbitrary limit of 126. This restriction should be removed, and if -anyone considers this a problem write me and let me know so I can remove -the constraint. -@end itemize - -@node Projects, Implementation, Bugs, Top -@chapter Things Still Left to Do - -It should be ``relatively'' easy to replace the current perfect hash -function algorithm with a more exhaustive approach; the perfect hash -module is essential independent from other program modules. Additional -worthwhile improvements include: - -@itemize @bullet -@item -Make the algorithm more robust. At present, the program halts with an -error diagnostic if it can't find a direct solution and the @samp{-D} -option is not enabled. A more comprehensive, albeit computationally -expensive, approach would employ backtracking or enable alternative -options and retry. It's not clear how helpful this would be, in -general, since most search sets are rather small in practice. - -@item -Another useful extension involves modifying the program to generate -``minimal'' perfect hash functions (under certain circumstances, the -current version can be rather extravagant in the generated table size). -Again, this is mostly of theoretical interest, since a sparse table -often produces faster lookups, and use of the @samp{-S} @code{switch} -option can minimize the data size, at the expense of slightly longer -lookups (note that the gcc compiler generally produces good code for -@code{switch} statements, reducing the need for more complex schemes). - -@item -In addition to improving the algorithm, it would also be useful to -generate a C++ class or Ada package as the code output, in addition to -the current C routines. -@end itemize - -@node Implementation, Bibliography, Projects, Top -@chapter Implementation Details of GNU @code{gperf} - -A paper describing the high-level description of the data structures and -algorithms used to implement @code{gperf} will soon be available.

If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - -@iftex -@unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION -@end iftex -@ifinfo -@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION -@end ifinfo - -@enumerate 0 -@item -This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License.

[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.
