Hi,
I tried something like this...
auto m = match("a=42 b=32 c=22", regex(`^(?: \s* (\w+)=(\d+)
)+$`, `x`));
This works fine...
`^(?: \s* (\w+)=(\d+) )+$`
... and if I duplicate the string x times, it also works...
But I'm hoping to parse a variable number of these 'pairs'...
so I tried
grouping the pairs in (?:)+ but this way it saves only the
last pair?
Anyone got an idea?
Yes, just use the global flag and drop ( )+.
Then this foreach ought to save the day:
foreach( m; match(..., `\s* (\w+)=(\d+) `, `gx`))
Bleh. Fixed:
foreach( m; match(..., regex(`\s* (\w+)=(\d+) `, `gx`)))
{
//some stuff with m[1] & m[2]
}
Throw in some experiment w.r.t. the end of line and you should
be fine.
Great, thanks for your quick support. :)
I actually did test `gx` but I failed to realise that I now have
to iterate over matches as well as captures... which makes
perfect sense when I pause to think about it.
