"in" identified as "imaginary", not "inches" about raku-physics-measure HOT 6 CLOSED

Hi @wayland - thanks for the feedback. The the .new constructor will parse Strings with the defn-extract regex

/^ ( <number> ) \s* ( <-[±]>* ) $/ [see Measure.rakumod line 102]

In this case, raku thinks the that 7.27i is a (complex) number. I think the best way to handle this corner case is to test for both number == complex && first letter = 'i' then insert space and reparse.

This to be closed in v0.0.4 - due in a few weeks.

Sounds good! In the meantime, I'm splitting it apart and putting a space in manually.

Here it is golfed. Turns out that defined assertion also gets Complex which we don't want.

my regex number is export {
    \S+                     #grab chars
    <?{ +"$/" ~~ Real }>    #assersion coerces via '+' to Numeric (Real && Complex)
    ##<?{ defined +"$/" }>    #assert coerces via '+' to Real
}

#my $s = '7m';
#my $s = '7 m'; 
my $s = '7in';
#my $s = '7 in';

$s ~~ /^ ( <number> ) \s* ( <-[±]>* ) $/;  

my $v = +"$0".Real if $0.defined;
my $u =  "$1".Str  if $1.defined;

say "extracting «$s»: v is «$v», u is «$u»";

Final version a bit cleaner...

my regex number is export {
	\S+                     #grab chars
	<?{ +"$/" ~~ Real }>    #assert coerces via '+' to Numeric (Real || Complex)
}

and

$s ~~ /^ ( <number> ) \s* ( <-[±]>* ) $/;  
my $v = +$0;
my $u = ~$1;

Hi @wayland - I have completed this as a HotFix to the Master branch here at GitHub. You can get right away with:

zef uninstall Physics::Measure
zef install --verbose https://github.com/p6steve/raku-Physics-Measure.git

or similar

Cool, thanks!
