How to make IEx print strings instead of charlists
Hi , Trying to understand why
Phoenix.HTML.Link.link("Home", to: '/')
is returning
{:safe, [60, "a", [[32, "href", 61, 34, "/", 34]], 62, "Home", 60, 47, "a", 62]}
instead of
{:safe, ["<a href=\"/\">", "Home", "</a>"]}
like I would expect.
I’m gathering that it’s showing the char codes, but also the nested arrays are throwing me off too.
Thanks for the help!

Hello and welcome,
It is because Phoenix templates use IO list for optimization…
See this post for more information.

Note that single quotes are for charlists. So the '/' you are passing in is not a string but a charlist. It’s a bit odd that it works at all, but when interfacing with Elixir libraries you should use double quoted string literals.

You can use just to_string btw.
