18:13 <postmodern> is it better to define methods that return/yield Int::Unsigned or some kind of type union for all possible values, or define the class as a generic that specifies the specific type that will be returned/yielded?

18:14 <FromGitter> <Blacksmoke16> prob the latter, but do you really need to be working with unsigned ints?

18:14 <FromGitter> <oprypin:matrix.org> postmodern, depends

18:15 <FromGitter> <Blacksmoke16> just because the value shouldnt be negative doesnt mean its "right" to use them

18:15 <FromGitter> <oprypin:matrix.org> agreed there too

18:16 <postmodern> it's for hexdumping code, so i'd prefer to keep them as unsigned. i'll eventually add support for printing signed words, then maybe floats as well

18:17 <FromGitter> <Blacksmoke16> https://crystal-lang.org/api/master/IO/Hexdump.html possibly helpful?

18:17 <postmodern> i'm more worried about word-size. if i'm only dumping 8bit or 16bit words, having a big type union seems needless

18:18 <postmodern> Blacksmoke16, yes i've seen IO::Hexdump and it's kind of limited, which is why i'm porting my hexdump ruby library to crystal

18:23 <FromGitter> <Blacksmoke16> 👍

19:07 <postmodern> can integer types automatically increase their size, or do you just have to decide whether to use Int32 or Int64 for counts/sizes?

19:08 <FromGitter> <Blacksmoke16> the latter

19:08 <FromGitter> <Blacksmoke16> well, is it an ivar or just a local var?

20:54 <postmodern> Blacksmoke16, ivar, since i initialize the Dumper class with the settings (word_size, endianness, base, etc), then #each_word is supposed to convert a byte stream into a word stream, which then gets formatted and written out

20:56 <FromGitter> <Blacksmoke16> yea, then in that case it would overflow

23:50 <FromGitter> <asterite> I would avoid int unions if possible. Why do you need them?
