a simple compression/decompression command line application using the zlib compression library and prints out some useful diagnostic information about the process.
- this program already has a pre-built binary in the
buildfolder namedSimComp.exe - alternate build versions can be created by altering the
CMakeLists.txtfile in the root directory of this project. - to use the project built as is, place a file which is to be compressed/decompressed in the root directory of this project and navigate to this root directory in the termianal.
- there are 4 flags which can be set and passed parameters whilst using this application:
-c[REQUIRED] signifies that the following arguement is a file to be compressed-l[OPTIONAL] the following arguement is the level of compression to be done [between 1 and 9]-d[REQUIRED] signifies that the following arguement is a file to be decompressed-o[REQUIRED] the following arguement is the output file which the output of compression/decompression will be written to.
An example showing the compression of the example.txt text file in the root directory is as follows:
./build/SimComp.exe -c example.txt -o compressed.bin -l 8
this compresses the text file to a binary file and prints out some useful diagnostic information.
An example of decompression using the above compressed file is as follows:
./build/SimComp.exe -d compressed.bin -o decomp.txt
this will produce a text file called decomp.txt that will contain the same contents as in the original example text file
