GENDICT(1) ICU 78.3 Manual GENDICT(1)

# [NAME](#NAME)

**gendict** - Compiles word list into ICU string trie dictionary

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#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](#OPTIONS)

[**-h, -?, --help**](#h)

Print help about usage and exit.

[**-V, --version**](#V)

Print the version of **gendict** and exit.

[**-c, --copyright**](#c)

Embeds the standard ICU copyright into the *output-file*.

[**-v, --verbose**](#v)

Display extra informative messages during execution.

[**-i, --icudatadir **directory****](#i)

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**](#uchars)

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

[**--bytes**](#bytes)

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

[**--transform**](#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**](#input)

The source file to read.

[**output-file**](#output)

The file to write the output dictionary to.

# [CAVEATS](#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](#ENVIRONMENT)

[**ICU\_DATA**](#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.
