Detailed Description

This class lexically analyzes a string, splitting it up into tokens, which are accessed as a vector.

This involves splitting at spaces, or better quoted strings. At any token, the untokenized, original remainder can also be retrieved.

Constructor & Destructor Documentation

ArgumentVector()

Parsnip::ArgumentVector::ArgumentVector

(

const StringType &

cmd

)

Construct an argument vector by splitting up a string into tokens.

• An empty/whitespace-filled string results in an empty vector.
• Strings may be quoted with single (apostrophe) or double quotes. The quote characters are omitted from their tokens.
• A literal of of the quote character may be inserted by doubling within the quoted region.
• A mismatched quote is not treated as an error; the token is taken from the character after the open quote to end of string.
