What CLI argument parsing library can you suggest?
Bish 2017-02-19 01:47:01
is that kinda like a macro?
Bish 2017-02-19 01:47:09
on what level that will be done?
lyxia 2017-02-19 01:47:12
delYsid: I highly recommend optparse-applicative

optparse-applicative
lyxia 2017-02-19 01:49:29
Bish: it's a construct within the language to name patterns like we name expressions with let.
lyxia 2017-02-19 01:49:54
it's only toplevel though
delYsid 2017-02-19 01:55:24
lyxia: looks nice, thanks

if I have a sum type S = A | B | C, is there a way to "or" two prisms? (_A <||> _B) or something

Hello! :) is there a way to surround code on here? `let x = "test"` or something?
lyxia 2017-02-19 02:42:23
bollu: failing does something along those lines
bollu 2017-02-19 02:42:30
chrisdotcode: what do you mean by surround?
bollu 2017-02-19 02:42:38
> let x = "test" in x ++ x
lambdabot 2017-02-19 02:42:40
"testtest"

lyxia: I need a way to know where to find what I need
lyxia 2017-02-19 02:43:35
yeah I'm not sure what's a good way...

I'm just starting to remember things from having gone through the whole library tens of times to answer this kind of question

anyone know how to fix the overlapping instance problem here http://lpaste.net/352712 I can't enable the last line, GHC complains, saying that two instance declarations overlap
chrisIrcTheFirst 2017-02-19 02:44:36
Haha, well anyway I've got that function and it's giving me an error of: Non type-variable argument
chrisIrcTheFirst 2017-02-19 02:44:36
in the constraint: ConvertibleStrings

lyxia: in terms of "real life use" going through lens?
