Atom 1.2.0 , OSX 10.11, Only limited ligatures working

[benjamin-rood]

atom-text-editor { text-rendering:optimizeLegibility } makes no difference.

Working:
!= <= >= /= == ^= >>= <<= ===
... (...)

Not Working:
-> => (all lengths)
->>
!== maps to != =
>>> (and reverse)
-<< (and reverse)
***
(all arrows)

It would be safe to assume that most of the rest are not working, but those are the ones I had a chance to try.

It may be that I am typing the wrong keys? But since some of the ligatures are working, I must be doing something correct?

(One other suggestion: Why not have a plaintext version of all symbol combinations in the README.md which produce ligatures. Then someone can just copy and paste the whole set into Atom, see which ones convert or not.)

Take a look at issue #63.

Hi weavejester, Yes, you are right, that is indeed the problem and an identical issue. When I try to enter a ligature in a comment line, they all seem to work fine. Thank you very much for correctly spotting the most likely candidate.
Related query: is there a list of the syntax definitions which are compatible / partially compatible / no functionality?
How can I help with the atom implementation? It seems nuts to me that say, if you are dealing with pointer indirection in C, that there is any difference between having the arrow and -> , surely the ligature is just for our viewing and the raw source code just has -> to preserve parsing?

Here’s text version of most of the ligatures:

a == b    a := b   a >= b
a != b    a |= b   a <= b
a === b   a ||=b   a <> b
a !== b   a .= b   a && b
a =:= b   a ~= b   a || b
a =/= b   a =~ b   a ?: b
a <=> b   a ~~ b   a >> b
a ..< b   a ?= b   b << a
a ... b   a /= b   s |> p
a ** b    a ^= b   p <| s
a :: b    a .. b

x ->  _  <- x   #(...)    /* ... */
x ->> _ <<- x   #[...]   /** ... */
x --> _ <-- x   #{...}    // ...
x =>  _  <= x   #_(...)  /// ...
x ==> _ <== x   #?(...)   ;; ...
x =>> _ <<= x   ~@(...)   {- ... -}
     a!!                 <!--...-->
     a??                    <.../>
     a++                   </...>
     a--                 

f >>= g   f +++ g
f =<< g   f --- g
f <=< g   f <+> g
f >=> g   f <*> g
f *** g   f <$> g
f &&& g   f <|> g
f ||| g   f -<< g
f >>> g   f >>- g
f <<< g   f >- g
          f -< g

Seems to be fixed in atom/language-javascript#259.

Just to note, there are multiple highlighting modes for JS and JSX, "Javascript (JSX)" seems to work best for me.

PHP still seems to have issues with it.
