Huffmancode program

Instruction on how to run program:

The program can be run with cmake as follows:

1 ) Enter the following command for an out of source build:

cmake -H. -Btmp_cmake -DCMAKE_INSTALL_PREFIX=$INSTALL_DIR

The $INSTALL_DIR is where you would like the program to be installed.

2. Navigate to the $INSTALL_DIR directory.

3. There will be two exectuable programs visible : demo and Huffmancoder

• The demo program exhibits a demonstration of the Huffmancoder program.
• Huffmancoder is the executable program

Using the Huffmancoder program

The Huffmancoder program can be run in two modes:

1. Standard input/output mode

   To activate this mode use the program as follows:

   -For compression mode use the command line argument -c and then press enter. Then you can enter input that you would like to have compressed.

   Example:  Huffmancoder -c
   
   Example: (with input pipelining and output printed to screen) Huffmancoder -c <input.txt  
   
   Example : (with input and output pipelining) Huffmancoder -c <input.txt >compressed_input.txt
   

   -For decompression mode use the command line argument -d and then press enter. Then you can enter the compressed input that you would ike to have decompressed.

   Example:(with no input or output pipelining, input taken from keyboard and output to screen)  
    
   Huffmancoder -d
   
   Example: (with input pipelining and output printed to screen) 
    
   Huffmancoder -d <compressed_input.txt 
   
   Example : (with input and output pipelining) 
   
   Huffmancoder -d <compressed_input.txt >decompressed_output.txt
   
   Similarly the program can run both compression and decompression run with outpipelining and input from keyboard. 
   

2. File input/output mode

   To activate this mode use the program as follows:

   -For compression mode use the command line argument -c followed by a space and then a name of a file to read input from.

   Example:  Huffmancoder -c input.txt 
   
   In File input/output mode compression will lead to a file being created titled "compressed.txt". 
   

   -For decompression mode use the command line argument -d followed by a space and then the name of a compressed file.

   Example:  Huffmancoder -d compressed.txt 
   
   In File input/output mode compression will lead to a file being created titled "decompressed.txt".
