Ligature requests for package magrittr (R)

[neuwirthe]

magrittr make piping (Haskell style) available in R. It is not only used in magrittr, but also gives the basic operator %>% in dplyr.

Therefore it would be helpful if we had the following operators as ligatures:

%$% magrittr exposition pipe-operator %<>% magrittr compound assignment pipe-operator %>% magrittr forward-pipe operator %T>% magrittr tee operator

Partial duplicate with #41.

Following my suggestion on #41 and #473, I would give less emphasis to the % signs, which just convey that these are custom binary operators (which will already be clear from the use of ligatures). I'd reduce each % to just a small vertically centered circle ∘.

So, for %>% I'd use ∘▷∘ (except I would stretch the triangle so it touches the circles).

Similarly:

• For %$% you could use ∘$∘ but extend the tips of the dollar sign to touch the circles
• For %<>%, you use something like the ligature for F#'s <|>, but add circles ∘ at the vertex of < and the vertex of >
• For %T>% you could use ∘T>∘, but join the right end of the T's cross bar to the top of the >, make the vertex of the > touch the right ∘, and make the left side of the T's cross-bar bend down at a right angle to touch the top of the left ∘. The result would be something like ⫰⊤>∘ but all linked together.
