text-lossy - lossy text compression via entropy reduction
text-lossy [-1|-2|-3|--filter <aa,bb,cc>|--paragraph] [file ...]
Options: - help This help - version Version of text-lossy - filter aa,bb,cc Add filters named 'aa', 'bb' and 'cc' to the process This option can also be given more than once - available-filters List of available filters - 1 Preset 1: filter 'lower' - 2 Preset 2: filters 'lower whitespace' - 3 Preset 3: filters 'lower punctuation_sp whitespace' - 2l Same as preset 2, but uses 'whitespace_nl' - 3l Same as preset 3, but uses 'whitespace_nl' - paragraph Read files in paragraph mode

Add one ore more named filters to use for this run. For multiple filters, you can either separate the names with commas, or use the
filteroption several times.
Returns a list of currently available filters. These names can be passed to the
filteroption. See Text::Lossy(3pm) or supporting modules for information on the filters.
- 1, 2, 3
Various presets that choose from sensible filter lists. Generally, higher numbers will compress better.
- 2l, 3l
Similar to presets
3, except that newline characters on the end of lines remain newline characters. Most useful if you wish to pipe line-oriented data through
text-lossywithout causing it to buffer the entire input. May reduce compression efficiency.
Reads files, or
STDIN, in paragraph oriented mode. In this mode, "paragraphs" are separated by one or more blank lines. Most useful in conjunction with the
3lpresets, or the
whitespace_nlfilter: the output will contain one line per paragraph in the input.
This script is a straight-forward application of the Perl moduleL <Text::Lossy(3pm)|Text::Lossy> to
STDIN or a set of files. Leave the list of files empty to read from
STDIN. The results are printed to
Note that this module does not perform the actual compression itself, it merely changes the text so that it may be compressed better. You will most likely need to add some form of actual compression at the end, e.g.
text-lossy -3 mytext.txt | gzip > mytext.txt.gz
