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-fileDescription
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/70.1/. 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.
