What is the purpose for the regexp -inline flag

I could only find usage for regexp -indices and regexp -nocase
What is the use for the regexp -inline
-Parag

[Bruce]

useful for directly using the matches without storing in a variable

foreach itemThatMatched [regexp -all -inline $RE $input] {

doStuffWith $itemThatMatched

}

or getting a list of stuff

set listOfNumbers [regexp -all -inline {\d+} $input]

It's brilliant - especially when used with -all! You get
all the match results as a list instead of needing to
invent variable names to store them. For example, consider
your "variable_name[index1][index2]..." problem (I guess
you're looking at Verilog source code???)

proc give_me_the_arrays {Verilog} {
return [regexp -inline -all {(\w+)((?:\s*\[\d+\])+)} $Verilog]
}

[note the noncapturing ?: in the innermost parentheses]

% set stuff [give_me_the_arrays {a[3]=test[6] [9] - junk[3]}]
{a[3]} a {[3]} {test[6] [9]} test {[6] [9]} {junk[3]} junk {[3]}

Now you can scan through the list using the fancy version of
"foreach" with multiple variables, so that it picks up the
list elements in groups of three:

foreach {complete_match variable subs} $stuff {
puts "variable name = $variable, subscripts = $subs"
}

You have old documentation and/or and old version of Tcl. The -inline
option was added in Tcl 8.3:
