Installation

Building instruction

mkdir build
cd build
cmake ..

Or, quicker :

./build.sh

To test if it works :

./test.sh

Installation instruction

Once build, run the following commands as root:

cd build
make install

Limitations

Follow the RFC 4180 by default. Further release may allow to change default separator character, in order to use a semi colon as an example.

In order to operate as fast as possible, the current implementation limits to 256 the number for fields that can be handled in the source stream. Further release may be more flexible and self scales to the number of columns in the source stream.
