GENDICT(1)

NAME
gendict - Compiles word list into ICU string trie dictionary

SYNOPSIS
gendict [ --uchars | --bytes --transform transform ] [ -h, -?, --help ] [ -V, --version ] [ -c, --copyright ] [ -v, --verbose ] [ -i, --icudatadir directory ] input-file output-file

DESCRIPTION
gendict reads the word list from dictionary-file and creates a string trie dictionary file. Normally this data file has the .dict extension.

Words begin at the beginning of a line and are terminated by the first whitespace. Lines that begin with whitespace are ignored.

OPTIONS

-h, -?, --help
    Print help about usage and exit.

-V, --version
    Print the version of gendict and exit.

-c, --copyright
    Embeds the standard ICU copyright into the output-file.

-v, --verbose
    Display extra informative messages during execution.

-i, --icudatadir directory
    Look for any necessary ICU data files in directory. For example, the file pnames.icu must be located when ICU's data is not built as a shared library. The default ICU data directory is specified by the environment variable ICU_DATA. Most configurations of ICU do not require this argument.

--uchars
    Set the output trie type to UChar. Mutually exclusive with --bytes.

--bytes
    Set the output trie type to Bytes. Mutually exclusive with --uchars.

--transform
    Set the transform type. Should only be specified with --bytes. Currently supported transforms are: offset-<hex-number>, which specifies an offset to subtract from all input characters. It should be noted that the offset transform also maps U+200D to 0xFF and U+200C to 0xFE, in order to offer compatibility to languages that require these characters. A transform must be specified for a bytes trie, and when applied to the non-value characters in the input-file must produce output between 0x00 and 0xFF.

input-file
    The source file to read.

output-file
    The file to write the output dictionary to.

CAVEATS
The input-file is assumed to be encoded in UTF-8. The integers in the input-file that are used as values must be made up of ASCII digits. They may be specified either in hex, by using a 0x prefix, or in decimal. Either --bytes or --uchars must be specified.

ENVIRONMENT

ICU_DATA
    Specifies the directory containing ICU data. Defaults to ${prefix}/share/icu/78.3/. Some tools in ICU depend on the presence of the trailing slash. It is thus important to make sure that it is present if ICU_DATA is set.
