parsing string, as if it were a command line

[nickelstat]

Hi, I'm looking for codes/modules that parse exactly like the command
line parser
(otherwise, I'll do the work myself)

Here is the story

When this command below is executed

perlScript -k b='this has blanks' -x "escape \" the quote"


I get $ARGV[0] = -k
[1] = b='this has blanks'
[2] = -x
[3] = escape " the quote

Note: this is one example. Hairy situations may be a combination of
lots of blanks and quotes and # variations.

Now I want to achieve the same thing, but the arguments are in a string

$string=qq# -k b='this has blanks' -x "escape \" the quote"#;

If not for the quotes and the blanks, I could do @ARGV = split /\s+/
but those blanks create problems

(I put double quotes in the value to show empty arguments
ARGV[0]=""
ARGV[1]="-k"
ARGV[2]="b='this"
ARGV[3]="has"
ARGV[4]="blanks'"
ARGV[5]="-x"
ARGV[6]=""escape"
ARGV[7]="""
ARGV[8]="the"
ARGV[9]="quote""

Thanks in advance

Have you looked at Getopt::Long (or other modules in the Getopt
family):

Understand Getopt assumes you use the command line.

Here I have a string, inside a script, that I want parsed to get @ARGV

Paul, I'll look into your suggestion.

And thanks guys for the very speedy answers. Just as if you were
sitting next to me.

See Paul's suggestion.

$string=qq# -k b='this has blanks' -x "escape \" the quote"#;

----------^^

You didn't mean to use qq// there, you meant to use the q// operator.

Thanks

I used &shellwords() and it does what I want.

Saves me lots of time.

Except that it didn't like leading blanks -> it gives me a blank as the
first token.

Really appreciate your inputs.

That will probably be _very_ challenging because each of the many, many
"command line parsers" has its own way of parsing the command line.
Ever noticed the differences between e.g. sh, bash, tcsh, cmd.exe, ....

Which command-line parser? ksh? sh? ash? zsh? bash? DOS 5.x? 4DOS? Windows
CMD? DR-DOS? csh? VMS? CP/M? AIX? TSO?

Sorry,
should have been more precise

The one that is common to ksh,csh,bash.
But I'm only interested in a small subset of the parsing, not the whole
thing.

Text:arseWords seems to do what I need.
