limit re of COMMAND #58

Closed huntzhan closed 9 years ago

huntzhan commented 9 years ago

currently, re of COMMAND:

COMMAND              {NON_SPACE}+

Supporting COMMAND with arbitrary pattern is expensive, it requires:

process doc before parsing, i.e. insert spaces between around keyword.
treat COMMAND as general element when processing input argument.

Decision:

reset the pattern of COMMAND to {LOWERCASE_DIGIT}({LOWERCASE_DIGIT}|{HYPHEN})*.(meaning that single dash - can not be a command)
introduce COMMAND type to input argument processing.
