# voikkospell(1)

test program for Voikko spell checker

## NAME

voikkospell - test program for Voikko spell checker

## SYNOPSIS

**voikkospell** \[*options*\]

## DESCRIPTION

**voikkospell** is a test program for spell checking functionality in libvoikko, library of language tools. It reads words from stdin (one word on a line) and print them to stdout, adding "C: " in front of correct words and "W: " in front of incorrect words.

Common options of different Voikko test programs are listed in COMMON OPTIONS.

## OPTIONS

- **-m**

  In addition to spelling result, prints morphological analysis info (A:) for recognized words.

- **-M**

  Prints morphological analysis info (A:) for recognized words without displaying spelling result.

- **-t**

  Prints only "C" or "W" instead of typical full output.

- **-tt**

  Prints only misspelled words.

- **-s**

  Prints suggestions (S:) for incorrectly spelled words.

- **-c***n*

  Set cache size parameter to *n*. -1 disables the cache and 0 is the default. For checking large amounts of unsorted text you may want to set *n* to 5 to get better performance.

- **-j** *n*

  Use *n* threads for spell checking. When more than one thread is used checking is performed using large internal buffers which is why this mode should only be used for batch processing.

- **-x***c*

  Like **voikkospell -s** but output is printed on one line separated by character *c* without "C", "W" or "S" in front of the words. If *c* is not defined words are separated by space and suggestions that have spaces in them are not printed.

- **-l**

  Prints a list of available dictionary variants and exits. The first variant is the default to be used when no specific variant has been requested.

- **-L**

  Prints a list of capabilities and languages for which these capabilities are supported.

- **ignore\_nonwords=***n*

  - **accept\_first\_uppercase=***n*

  - **accept\_all\_uppercase=***n*

  - **accept\_extra\_hyphens=***n*

  - **accept\_missing\_hyphens=***n*

  - **ocr\_suggestions=***n*

  Set the value of the specified boolean option. *n* can be either 0 (false) or 1 (true).

## COMMON OPTIONS

- **-p** *directory*

  (voikkospell, voikkohyphenate, voikkogc) Look from *directory* before the standard locations when searching for dictionary files.

- **-d** *variant*

  (voikkospell, voikkohyphenate, voikkogc) Use dictionary variant *variant* instead of the default dictionary variant. The variant must be represented as a BCP 47 language tag.
