F-Strings

[froggestspirit]

I know this has been mentioned a little in the past, but it would be nice to see f-string support for the GDScript language.
https://docs.python.org/3/tutorial/inputoutput.html
I don't think it would need to be as in depth as python 3 (unless it works fine that way?), but something like
f"The value of x, is {x}" would be nice, and require less than format strings.

Isn't that what the "%" character in strings is for (Doc) ?

[froggestspirit]

Yes, but it’s an alternative way to utilize it. Instead of
var script = "GDScript"
var name = "Estragon"
var format_string = "%s was reluctant to learn %s, but now he enjoys it."
var actual_string = format_string % [name, script]

it would be

var script = "GDScript"
var name = "Estragon"
var format_string = f"{name} was reluctant to learn {script}, but now he enjoys it."

FWIW, the String.format() method has a similar syntax:

var script = "GDScript"
var name = "Estragon"
var format_string = "{name} was reluctant to learn {script}, but now he enjoys it."
var actual_string = format_string.format({"name": name, "script": script})

It's a handy function that accepts plenty of different ways to format the string.

Its similar to C#:
$"string_literals {var_name} string_literals {obj.method()}";
pretty handy

also for keep tabulation and new lines:
@"string_literals
string_literals
string_literals";
(the new lines are preserved in the string)

Tbh feel the current f-strings in GDScript different than other languages (in a bad sense), it doesn't like me.

There is already a proposal:

• Add literal quoted strings with embedded variables (f-strings) to GDScript #157

Let's close this discussion for consolidation. Thanks for the contribution nonetheless!
