Member Function Documentation

vector< string > Parse_Single_Command::parse ( )

virtual

Parses a single command into exe and parameters.

Returns

a vector of strings where the first element is the exe and following are each parameter

Only the Command class instantiates this class.

The parse function is broken into several steps: STEP 1 - ELIMINATE EXTRANEOUS SPACE NOT IN QUOTES STEP 2 - DIVIDE BY SPACES, |, <, > and >> STEP 3 - REMOVE ANY SETS OF QUOTES STEP 4 - REMOVE ANY EMPTY STRINGS

This parsing function does not handle connectors (&& || or ;) nor does it handle comments (#comments) and it does not expect them in the string. This is because those should have been parsed by Parse_Multi_Command prior to being sent to a Command Class.

Implements Parse.
