genctd: Compiles word list into ICU compact trie dictionary


genctd - Compiles word list into ICU compact trie dictionary


genctd [ -h, -?, --help ] [ -V, --version ] [ -c, --copyright ] [ -v, --verbose ] [ -d, --destdir destination ] [ -i, --icudatadir directory ] -o, --out output-file dictionary-file


genctd reads the word list from dictionary-file and creates a compact trie dictionary file. Normally this data file has the .ctd extension.

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


-h, -?, --help
Print help about usage and exit.
-V, --version
Print the version of genctd and exit.
-c, --copyright
Embeds the standard ICU copyright into the output-file.
-v, --verbose
Display extra informative messages during execution.
-d, --destdir destination
Set the destination directory of the output-file to destination.
-i, --icudatadir directory
Look for any necessary ICU data files in directory. For example, the file 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.
The source file to read.
-o, --out output-file
The output data file to write.


When the dictionary-file contains a byte order mark (BOM) at the beginning of the file, which is the Unicode character U+FEFF, then the dictionary-file is interpreted as Unicode. Without the BOM, the file is interpreted in the current operating system default codepage. In order to eliminate any ambiguity of the encoding for how the rule-file was written, it is recommended that you write this file in UTF-8 with the BOM.


Specifies the directory containing ICU data. Defaults to /usr/share/icu/4.2.1/. 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.
