NAME

word−list−compress − word list compressor/decompressor for GNU Aspell

SYNOPSIS

word-list-compress c[ompress] | d[ecompress]

DESCRIPTION

word-list-compress compresses or decompresses sorted word lists for use with the GNU Aspell spell checker.

COMMANDS

−c, c, compress

compress the plain text word list read from standard input.

−d, d, decompress

decompress the compressed word list read from standard input.

EXAMPLES

Here are a few examples of how you can use word−list−compress
word−list−compress d <wordlist.cwl >wordlist.txt

Decompress file wordlist.cwl to text file wordlist.txt

word−list−compress c <wordlist.wl >wordlist.cwl 2>errors.txt

Compress wordlist.wl to wordlist.cwl and send any error messages to a text file named errors.txt

LC_COLLATE=C sort −u <wordlist.txt | word−list−compress c >wordlist.cwl

Sort a word list, then pipe it to word−list−compress to create a compressed binary wordlist.cwl file.

word−list−compress d <words.cwl | aspell create master ./words.rws

Decompress a wordlist, then pipe it to aspell(1) to create a spelling list. Please check the aspell(1) info manual for proper usage and options.

TIPS

Word−list−compress is best used with sorted word list type files. It is not a general purpose compression program since the resulting files may actually increase in size.

Word−list−compress accepts up to 255 text characters in the range of {0x21...0xFF}. If your word list requires a larger character set for certain languages or longer length for multi−word, scientific, medical, technical or other use, then it is recommended that you compress your word list using prezip−bin(1)

DIAGNOSTICS

Word−list−compress normally exits with a return code of 0. If it encounters an error, a message is sent to standard error output (stderr), and word−list−compress exits with a non-zero return value. Error messages are listed below:
(display help/usage message)

Unknown command given on the command line so word−list−compress displays a usage message to standard error output.

Corrupt Input

This is only for the decompression command d. The input file is of an unknown format or the input file/stream is corrupted. You may have some valid output, but word−list−compress could not complete the process. If the input file is a compressed wordlist but you have no output file, then it may be a newer prezip−bin(1) version of compressed file, if so, try decompressing the file with prezip−bin(1) instead.

Output Data Error

The output is full, write protected, or has an error and can no longer be written to.
