Some notes for beginners on how to pronounce those strange Haskell operators etc.
This is just a rough start to this page. Obviously needs more work.
This can be a table with formal and informal ways of saying various operators and code snippets such as
| Symbol | Pronunciation |
|---|---|
::
|
has type (in definitions); at type (in expressions or patterns) |
->
|
maps to, to |
=
|
is |
==
|
equals |
/=
|
not-equals |
=>
|
is a witness for, implies |
.
|
dot (could be used anywhere, but especially in, for example, Data.Char.ord), ring, compose (for example, negate . (+1)), (silent) (for example, forall a. (Num a) => a) |
<-
|
drawn from, from |
-<
|
|
++
|
append |
>>=
|
bind |
>>
|
then |
\
|
lambda |
!
|
bang; strict (in patterns or data definitions); index (in expressions) |
~
|
irrefutable, lazy (in patterns) |
:
|
cons |
[]
|
nil |
()
|
unit |
(,)
|
2-tuple, pair |
(a,b,c)
|
[3-]tuple [of] a, b, and c |
({)}
|
just as inconvenient to convey grouping verbally, whether it's layout or punctuation |
| Example | Pronunciation |
|---|---|
f :: Int -> Int
|
f has type Int to Int |
should we add informal, possibly bad suggestions like "then", "is", "gets"?
