00:00 <FromGitter> <Blacksmoke16> ... i did suggest using make and you said you did and still errors

00:01 <FromGitter> <Blacksmoke16> because make is the primary entrypoint into compiling crystal

00:01 <FromGitter> <Blacksmoke16> a PR to add it would be 🙏

00:01 <FromGitter> <lebogan> Yes, I used make but without the target= flag. My mistake :faceplant:

00:02 <FromGitter> <Blacksmoke16> even then im surprised it would happen even w/o that...

00:03 <FromGitter> <Blacksmoke16> also i had no idea make has auto generated help like that

00:03 <FromGitter> <Blacksmoke16> is pretty sweet

09:59 <frojnd> Hi there.

10:00 <frojnd> I'm trying to copy file that is inside .zip Not read it. I know how to read it https://crystal-lang.org/api/1.4.1/Compress/Zip/File.html but is there a way to copy it somewhere so I can than use other system apps to manipulate/use that file?

10:26 <FromGitter> <oprypin:matrix.org> frojnd, open the file from zip, you get a readable io. inside, open the destination path, you get a writable io. inside, use https://crystal-lang.org/api/1.4.1/IO.html#copy%28src%2Cdst%29%3AInt64-class-method

10:53 <frojnd> @oprypin I think I'm missing the writable io? https://carc.in/#/r/d4oo

10:55 <FromGitter> <oprypin:matrix.org> frojnd, yea that would be https://crystal-lang.org/api/1.4.1/File.html#open%28filename%3APath%7CString%2Cmode%3D%22r%22%2Cperm%3DDEFAULT_CREATE_PERMISSIONS%2Cencoding%3Dnil%2Cinvalid%3Dnil%29%3Aself-class-method

10:56 <FromGitter> <oprypin:matrix.org> IO::Memory shouldn't be involved.

10:58 <frojnd> So I should ditch https://crystal-lang.org/api/1.4.1/IO.html#copy%28src%2Cdst%29%3AInt64-class-method "def self.copy" and rather try the https://crystal-lang.org/api/1.4.1/File.html#open%28filename%3APath%7CString%2Cmode%3D%22r%22%2Cperm%3DDEFAULT_CREATE_PERMISSIONS%2Cencoding%3Dnil%2Cinvalid%3Dnil%29%3Aself-class-method (def self.open(filename : Path | String, mode = "r", perm =

10:58 <frojnd> DEFAULT_CREATE_PERMISSIONS, encoding = nil, invalid = nil) : self) ?

11:06 <frojnd> @oprypin https://carc.in/#/r/d4op I get No such file

11:06 <frojnd> But then again maybe I don't understand how to write to file

11:07 <FromGitter> <oprypin:matrix.org> frojnd, maybe the directory "some_file" doesn't exist

11:08 <FromGitter> <oprypin:matrix.org> the code is all good, also should delete this line as well `io = IO::Memory.new io.gets_to_end`

11:08 <frojnd> @oprypin it doesn't since it didn't extract it. Hm I have to create it by hand?

11:08 <FromGitter> <oprypin:matrix.org> yes

11:09 <frojnd> If I delete that io line, what should I put inside IO.copy()

11:11 <frojnd> Just IO.copy(io.gets_to_end, f)

11:13 <FromGitter> <oprypin:matrix.org> literally just delete that line, no other change compared to https://carc.in/#/r/d4op ⏎ that is because you already have |io|

11:14 <FromGitter> <oprypin:matrix.org> frojnd,

11:15 <frojnd> I see

11:15 <frojnd> I have to use typeof more often in this lerning proccess

11:15 <frojnd> Thank you oprypin

13:15 <Sankalp> Hi #crystal-lang

13:16 <FromGitter> <Blacksmoke16> o/

13:16 <Sankalp> Set{1,2,3}.map(...) returns an Array

13:17 <Sankalp> Is this expected?

13:18 <FromGitter> <Blacksmoke16> i think so

13:18 <FromGitter> <Blacksmoke16> could call `.to_set` on it

13:19 <Sankalp> True

13:21 <FromGitter> <Blacksmoke16> https://crystal-lang.org/api/1.4.1/Enumerable.html ⏎ ⏎ > Note that most search and filter methods traverse an Enumerable eagerly, producing an Array as the result. For a lazy alternative refer to the Iterator and Iterable modules.

13:22 <Sankalp> Ahh.. I see.

13:22 <Sankalp> Thank you, Blacksmoke16!
