<RX14> it's most likely an escaping issue in the string

<RX14> yup

<RX14> you need a %q string

<RX14> so that backslash escapes are processed properly

<RX14> it's literally because you pasted it into a string literal

<RX14> that \ chars needed to be doubly escaped

<RX14> or use %q

bmcginty, about your issue with libgen not removing common prefixes, I just had the same and fixed it: you need a rename rule, that remove the prefix from the fun name

<alex``> How to get the API documentation for offline usage?

<alex``> https://crystal-lang.org/api

Ghost

@ghost~55586c4815522ed4b3e08557

you can generate the documentation from the crystal code with make doc

Hi guys, I hope you are all doing well! :)
I need some help about the langage.
Can we translate a String to Symbol ?
My problem is: I get a list of file in a folder, and I want to call the function inside (that have the same name of the file).

thanks for the answer

John Jansen

@johnjansen

You can't dynamically create symbols. When you compile your program, each symbol gets assigned a unique number.

@FromIRC

<Papierkorb> @Jeremy-Pichon, there's no #send like in Ruby either. Use a case statement instead.

Jeremy Pichon

@Jeremy-Pichon

ok, thanks a lot :+1:

is there a method like .sub but that its adding something?

Ghost

@ghost~55586c4815522ed4b3e08557

do you have an example input/output?

From IRC (bridge bot)

@FromIRC

<oprypin> @LuckyChicken91_twitter, i noticed that last time you used sub(index, "") and you see it only as deleting something maybe? well obviously it doesnt have to be that way

LuckyChicken

@LuckyChicken91_twitter

okay

im still a bit conditined to ruby that you can do string[0] += "text" but unfortunately this doesnt work in crystal

John Jansen

@johnjansen

string[0] returns a char, not a string

LuckyChicken

@LuckyChicken91_twitter

i know

Ghost

@ghost~55586c4815522ed4b3e08557

If I understand correctly, you want to insert some text at a specific position of the string?

LuckyChicken

@LuckyChicken91_twitter

yes

excatly

Bar Hofesh

@bararchy

btw, why don't we have String#gsub!() ?

LuckyChicken

@LuckyChicken91_twitter

yes! why?

From IRC (bridge bot)

@FromIRC

<RX14> strings aren't mutable

Bar Hofesh

@bararchy

LuckyChicken

@LuckyChicken91_twitter

ouh

From IRC (bridge bot)

@FromIRC

<oprypin> @LuckyChicken91_twitter, so, like, when you decide what you actually want to do, maybe you could ask that, instead of "how can I do this weird thing from Ruby"

LuckyChicken

@LuckyChicken91_twitter

okay will do this next time

but im saying sometimes "because this is not working: Some code" so that people better understand what im meaning
