What is the keyboard shortcut for ⇒ in your Scala editor?

Question

The Unicode \u21D2 " ⇒ " operator (sometimes referred to as => ) is the common lexical identifier prevailing in the Scala programming language used in functional combinators, function definitions, case arguments, etc. I usually have to copy and paste this statement into my code from another place, but this can be very annoying.

Does anyone know of shortcuts for creating this symbol in your IDE? I usually use programs like JetBrains IntelliJ, SublimeText, and VIM.

Answer 1

IntelliJ IDEA under

Settings -> Editor -> CodeStyle -> Scala

In the "Other" tab, there are options for automatically inserting multiple characters in Unicode.

Answer 2

In IntelliJ, I created a live form template of $PARAMS$ ⇒ $BODY$ . This makes it easy to insert the ⇒ symbol.

Answer 3

For emacs, there (global-prettify-symbols-mode) , which simply displays ⇒ over => . It still writes => to the file at the end.
