an anyone explain me what I'm doing wrong here :
[code]
dstring[][dstring] providor_symbol_map;
...
writeln(providor_symbol_map.keys.sort!((x,y)=providor_symbol_map[x].length=providor_symbol_map[y].length));
[/code]
output:
core.exception.RangeError@std.algorithm(9429): Range violation

I'm trying to analyze the usage of certain words in a large number of spam
emails, and I want for every interesting word a list of 'providors', that
mentioned that word. with associative arrays I hoped to get it by using
array[interestingworde].
And I have to refer outside from sort(x,y) as
maarten van damme:
writeln(providor_symbol_map.keys.sort!((x,y)=providor_symbol_map[x].length=providor_symbol_map[y].length));
[/code]
Try:
((x, y) = providor_symbol_map[x].length
providor_symbol_map[y].length)

Sorry about typo, I meant
providor_symbol_map.sort!((x,y)={x.value.lengthy.value.length})
above.
Aha, so you want to maintain spam word - set of senders
relationship, so it's actually map of sets and your declaration
is correct. You only need to sort map's entries (key and value
pairs together).
If D supports that, it should be something like
Wanderer:
providor_symbol_map.sort!((x,y)={x.value.length=y.value.length}),
This lambda doesn't return a boolean. Also, add spaces around
operators and after commas.

wow.
senpai, teach me what I did wrong...

providor_symbol_map is an Associative Array, so you can't sort
that. *Usually*, you want to do what the OP did, which is to get
