User guide

The project has a simple command line interface.

Usage: <main class> [-dhv] [--performance] [--showbwt] -m=<method> <filepath>
      <filepath>          The file to compress.
  -d, --decompress        decompress the given file using chosen method
  -h, --help              displays a help message
  -m, --method=<method>   compression method: 'l' for LZSS or 'b' for BWT + RLE
      --performance       run performance tests
      --showbwt           displays the BWT transformation of the input
  -v, --verify            decompresses the file and verifies that the
                            decompression matches original content                       

You can run the project using gradle

./gradlew <filename> -m <l or b>

or build the project using

./gradlew fatJar

and run

java -jar tirautin <filename> -m <l or b> <additional flags>

There is also a ready made jar -file in releases. Please notice that the config.properties -file included in the releases needs to be in the same folder as the jar -file that is being run.

I've included two files: poem.txt is a poem in English and nucleotide-sample.txt contains some DNA sequences.
