Dear all, Thank you very much for the response and kind explanation. After studying, I will submit to ghc-proposals :) Regards, Takenobu 2017-09-26 22:56 GMT+09:00 Merijn Verstraaten : > I, too, have wished for the ability to have a separator in large number >

Re: Underscore in binary literals

I, too, have wished for the ability to have a separator in large number literals. So a strong +1 from me. Cheers, Merijn > On 26 Sep 2017, at 15:43, Ben Gamari wrote: > > Takenobu Tani writes: > >> Hi Rahul, >> >> Thanks for the explanation.

Re: Underscore in binary literals

I'd find that quite useful for hex and binary. It's useful for distinguishing e.g. 0x and 0xfff which when confused accidentally and lead to big bugs. Rust has exactly this feature for all numeric literals: https://rustbyexample.com/primitives/literals.html On 26/09/17 14:40,

Re: Underscore in binary literals

Hi, I for one, would like to have this in more than just BinaryLiterals (which I find rather useful as well!) I’d like to see `_` in any numeric literal being simply ignored, as I find it makes writing and reading numbers in source code much easier. let i = 1_000_000 :: Int f =

Hi Rahul, Thanks for the explanation. Hmm, Is not there much need... Thank you code example. I will also look at lexer for my study [1]. [1]: https://phabricator.haskell.org/D22 Thank you :) , Takenobu 2017-09-26 21:58 GMT+09:00 Rahul Muttineni : > Implementation-wise,

Re: Underscore in binary literals

Implementation-wise, it's no so difficult to include - the lexer needs to be tweaked. But it seems like a specialised use-case that will only affect a minority of users is probably not worthwhile as an extension to the language/compiler. Maybe you can try using OverloadedStrings and implement

Underscore in binary literals

Dear devs, GHC's BinaryLiterals extension is useful. (For example, x = 0b110111000101) Is it difficult to include underscore(_) in the format like Verilog-HDL[1] ? (For example, x = 0b1101_1100_0101) [1]: https://inst.eecs.berkeley.edu/~cs150/fa06/Labs/verilog-ieee.pdf#page=20 Regards,
