How do you actually type ⇒ in editor like Intellij Idea?

[Henry Saputra]

HI Guys, I just pulled the latest code from master and just found out the "=>" has been changed to "⇒" character in the source code with commit for https://github.com/spray/spray/issues/213

So, how do we insert this kind of symbols using editor like IDEA to update the code?

Thanks,

Henry

Hi,

AFAIK they are interchangeable. You can use either or them. Scala will interpret them the same way.

In case of spray, this is done by the plugin https://github.com/sbt/sbt-scalariform which formats the source code pre-compile. The arrows are in the setting rewriteArrowSymbols.

Yep, exactly. We followed the example from akka and it seems to us
like a good compromise: type the ASCII characters which get then
automatically exchanged into the nicer looking unicode symbols for
better readability.

I think this information merit itself to be added to Scala how to
contribute or code standard page?

You mean for spray? Yeah, maybe that would make sense.

If you're using Linux, I highly recommend taking advantage of the X11 Compose feature.

I have my Compose key set to Scroll Lock (it's in the KDE settings, dunno about anything else), and this is my ~/.XCompose file:

include "/usr/share/X11/locale/en_US.UTF-8/Compose"

<Multi_key> <less> <equal>      : "⇐" U21D0 # LEFTWARDS DOUBLE ARROW

<Multi_key> <equal> <greater>   : "⇒" U21D2 # RIGHTWARDS DOUBLE ARROW

<Multi_key> <a> <r> <r>         : "☠" U2620 # SKULL AND CROSSBONES

<Multi_key> <s> <n> <o> <w>     : "☃" U2603 # Snowman

Thanks Johannes, I will try to find the right place to add this info
into Spray site/doc.
