The &*\fBquotewords()\fR functions simply call &\fBparse_line()\fR, so if you're only splitting one line you can call &\fBparse_line()\fR directly and save a function call. .PP The \f(CW$keep\fR argument is a boolean flag. If true, then the tokens are split on the specified delimiter, but all other characters (including quotes and backslashes) are kept in the tokens. If \f(CW$keep\fR is false then the &*\fBquotewords()\fR functions remove all quotes and backslashes that are not themselves backslash-escaped or inside of single quotes (i.e., &\fBquotewords()\fR tries to interpret these characters just like the Bourne shell). \s-1NB:\s0 these semantics are significantly different from the original version of this module shipped with Perl 5.000 through 5.004. As an additional feature, \f(CW$keep\fR may be the keyword \*(L"delimiters\*(R" which causes the functions to preserve the delimiters in each string as tokens in the token lists, in addition to preserving quote and backslash characters. .PP &\fBshellwords()\fR is written as a special case of &\fBquotewords()\fR, and it does token parsing with whitespace as a delimiter\*(-- similar to most Unix shells. .SH "EXAMPLES" .IX Header "EXAMPLES" The sample program: .PP .Vb 7 \& use Text::ParseWords; \& @words = quotewords(\*(Aq\es+\*(Aq, 0, q{this is "a test" of\e quotewords \e"for you}); \& $i = 0; \& foreach (@words) { \& print "$i: <$_>\en"; \& $i++; \& } .Ve .PP produces: .PP .Vb 6 \& 0: <this> \& 1: <is> \& 2: <a test> \& 3: <of quotewords> \& 4: <"for> \& 5: <you> .Ve .PP demonstrating: .IP "0" 4 a simple word .IP "1" 4 .IX Item "1" multiple spaces are skipped because of our \f(CW$delim\fR .IP "2" 4 .IX Item "2" use of quotes to include a space in a word .IP "3" 4 .IX Item "3" use of a backslash to include a space in a word .IP "4" 4 .IX Item "4" use of a backslash to remove the special meaning of a double-quote .IP "5" 4 .IX Item "5" another simple word (note the lack of effect of the backslashed double-quote) .PP Replacing \f(CW\*(C`quotewords(\*(Aq\es+\*(Aq, 0, q{this is...})\*(C'\fR with \f(CW\*(C`shellwords(q{this is...})\*(C'\fR is a simpler way to accomplish the same thing. .SH "SEE ALSO" .IX Header "SEE ALSO" Text::CSV \- for parsing \s-1CSV\s0 files .SH "AUTHORS" .IX Header "AUTHORS" Maintainer: Alexandr Ciornii <alexchornyATgmail.com>. .PP Previous maintainer: Hal Pomeranz <pomeranz@netcom.com>, 1994\-1997 (Original author unknown).
