08:00:27FromGitter<kayabaNerve> I think the biggest problem wasn't even with the suggested operator (~); it was with requiring Nim to be run from a certain directory so code would work.

13:51:57enthus1astthere is no thing like a "file's MIME type"
13:52:36enthus1astsome files are so kind and store some magic bytes at the start or at the end
13:52:42enthus1astfor example zip (pk)
13:52:52enthus1astor windows executable (mz)

15:15:19FromGitter<JasperJenkins> @arnetheduck Tuple assignments aren't very strict, so you can discard the last items implicitly by assigning to a shorter tuple. See PR https://github.com/nim-lang/Nim/pull/11348 (which would change this behavior) for examples.
15:17:43FromGitter<arnetheduck> @JasperJenkins interesting, though it's the kind of trick to avoid it seems - it also wouldn't cover `(a, _, b)`?
15:21:29FromGitter<JasperJenkins> Yeah. Just assigning to a temp var like the compiler does seems the best option.

15:35:37Araqso ... closures are beginning to compile with --newruntime. Unfortunately they crash at runtime :P
15:37:59FromGitter<arnetheduck> are all nil dereferences supposed to be raised as nim exceptions (with checks:on)? I'm getting `Illegal storage access. (Attempt to read from nil?)` in a debug build
15:41:15Araqnah, hardly any nil checks are emitted
15:42:06AraqI tried to use ' -fsanitize=null -fsanitize-undefined-trap-on-error' to make the C compiler do it for us but my programs then die
15:42:18Araqprobably I misunderstand what these switches do.
15:49:37*nsf quit (Quit: WeeChat 2.4)
15:49:52FromGitter<arnetheduck> so.. why are.. any nil checks emitted? ie it gives a false kind of security.. specially to the exception loving crowd that might expect to be able to catch them

16:58:55Acid147Is it currently possible to include assembly files in the build process? I found no compiler option for that and executing something before the build process with nimble doesn't seem to work (https://github.com/nim-lang/nimble/issues/606)
17:09:52ZevvI guess you could {.emit.} asm blocks

17:19:35Acid147Thanks. Not the option I hoped for, because I would have to include the code in Nim files. But I'll try it if I don't find another solution
17:20:22Zevvwell, to be honest, I wouldn't do it like this
17:20:30ZevvI'd make a little helper lib from the asm code
17:20:37Zevvand link that when compiling nim code
17:21:41Acid147That would mean that I need to build the assembly code seperately from my Nim project, right?
17:22:12Zevvindeed. Nim does not know anything about assembly, so it wouldn't know how to invoke your assembler
