fsa_spell

NAME

fsa_spell - find words in dictionary or propose replacements

SYNOPSIS

fsa_spell [ options ] [ <infile ] [ >outfile ]

DESCRIPTION

fsa_spell reads lines from the input. Each line contains one word. Every word is looked up in specified dictionaries. If the word is not found, similar words are listed. The degree of similarity is controlled by the edit distance option.

OPTIONS

-d dictionary

use that dictionary. Several dictionaries may be given. At least one dictionary must be specified. Dictionaries are automata built using fsa_build or fsa_ubuild.

-e edit_distance

if the word is not in the dictionaries, look for words that lie within the specified distance. The edit distance is a number of basic editing operations needed to transform one string into another. Those operations are: inserting one character, deleting one character, changing one character, and transposing two adjacent characters.

-f

force search for replacement candidates (words within given edit distance) even if the word is in the dictionary. This may be useful in situations when an incorrect spelling of a word is identical to the correct spelling of another word. Use with caution.

-i input_file

specifies a file with words to be corrected. More than one file can be specified in this way (i.e. the option can be used more than once). In absence of this option, standard input is used.

-l language_file

specifies a file that holds language specific information, i.e. (for now) characters that form words, and pairs of (lowercase, uppercase) characters for case conversion. If the option is not specified, latin letters with standard case conversions wil be used.

-r character_class_file

specifies a file that information about relation between single characters and two-character sequences. If a two-letter sounds the same as one (different) letter, that relation can be established in this file, and the replacement of the first with the second will be treated as being one edit distance unit apart. The first character of this file is a comment character - all lines beginning with it will be ignored. Data lines consist of two columns. Both columns specify either a single character or a two-character sequence, but the sum of the number of characters should be three. The first column specifies something that may (incorrectly) appear in text, the second one - the correct form.

-v

prints version details.

EXIT STATUS

0

OK

1

Invalid option, or lack of a required option.

2

Dictionary file could not be opened.

4

Not enough memory.
