NAME

       trietool-0.2 - trie manipulation tool

SYNOPSIS

       trietool-0.2 [ options ] trie command arg ...

DESCRIPTION

       trietool-0.2  is the command-line tool for manipulating double-array trie data.  It can be
       used to query, add and remove words in a trie.

   The Trie
       The trie argument specifies the name of the trie to manipulate.  A trie  is  stored  in  a
       file  with  `.tri'  extension.  However, to create a new trie, one needs to prepare a file
       with `.abm' extension, describing the Unicode ranges of alphabet set of the trie.  The ABM
       defines  a set of vectors that map Unicode characters into a continuous range of integers.
       The mapped integers will be used as internal alphabet for  the  trie.   Such  mapping  can
       improve  the  space  allocation  within the trie data, regardless of non-continuity of the
       character set being used, as the mapped range is always continuous.

       The ABM file is a plain text file, with each line listing a range of 32-bit Unicodes to be
       added to the alphabet set, in the format:

              [0xSSSS,0xTTTT]

       where  `0xSSSS'  and `0xTTTT' are hexadecimal values of starting and ending character code
       for the range, respectively.

       For example, for a dictionary that contains only English words  witout  any  punctuations,
       one may prepare `trie.abm' as:

              [0x0041,0x005a]
              [0x0061,0x007a]

       The first line lists the ASCII codes for A-Z, and the second for a-z.

       No more than 255 alphabets are allowed in a trie.

       The  created  `.tri'  file  will  incorporate  the  ABM  data.  So, the `.abm' file is not
       required after the first creation, and will be ignored.

COMMANDS

       Available commands are:

       add word data ...
              Add word to trie, associated with integer data.   Arbitrary  number  of  words-data
              pairs  can  be  given.   Two  arguments  will  be read at a time, the first will be
              treated as word, and the second as data.

       add-list [ options ] list-file
              Add words with associated data listed in list-file to trie.  The list-file must  be
              a  text  file  listing one word per line.  The associated data can be put after the
              word in the same line, separated with tab (`\t') character.  If the data  field  is
              omitted, a default value (-1) will be used instead.

              Options are available for this command:

              -e, --encoding enc
                     Specify  character  encoding of the list-file contents, such as `UTF-8'.  If
                     omitted, current locale codeset is assumed.

       delete word ...
              Delete word from trie.  Arbitrary number of words to delete can be given.

       delete-list [ options ] list-file
              Delete words listed in list-file from trie.  The list-file  must  be  a  text  file
              listing one word per line.

              Options are available for this command:

              -e, --encoding enc
                     Specify  character  encoding of the list-file contents, such as `UTF-8'.  If
                     omitted, current locale codeset is assumed.

       query word
              Search for word in trie.  If  word  exists,  its  associated  data  is  printed  to
              standard  output.   Otherwise,  error  message  is  printed to standard error, with
              nothing printed to standard output.

       list   List all words in trie to standard output.  The output lists one word-data pair per
              line,  separated  with tab (`\t') character, the format appropriate for being list-
              file for the add-list command.

OPTIONS

       This program follows the usual GNU command line syntax, with long  options  starting  with
       two dashes (`--').  A summary of options is included below.

       -p, --path dir
              Set trie directory to dir [default=`.']

       -h, --help
              Show summary of options.

       -V, --version
              Show version of program.
