In case you weren't aware you can indent . chaining in Nim like this too if you 
like: [https://play.nim-lang.org/#ix=2bRv](https://play.nim-lang.org/#ix=2bRv)

It's just a styling thingy. Having every step of the pipeline on a separate 
line with same indentation just looks cleaner. Thanks for your hint, though!

Well operators that are also used for line continuations have to be written 
like this:


a |>

There are already several libraries for this in Github

Pipe operator in Nim

2020-02-14 Thread schmidh 
Is there any chance to get hold of the AST in a language construct where you 
define your own pipe operator as found e.g. in F#? (The point being that it 
should span multiple lines.)


"Hello"
|> echo


Run

It parses but it seems impossible to get access to the whole thing and 
manipulate it:


dumpTree:
  "Hello"
  |> echo


Run

The result is: 


StmtList
  StrLit "Hello"
  Prefix
Ident "|>"
Ident "echo"


Run
