Maybe some C exercises would help
Note that modpg.unit and rescnt.uint are not plain casts (reinterpretation of
bit pattern) but type conversions. Type conversions may ensure that the values
are not negative before conversion and raise exceptions otherwise. I don't
rotated = rotated or rotated # is this correct?
I doubt this is correct. For any `x`: expression `x or x` gives just `x`
(always), so this line is equivalent to
rotated = rotated
which is pointless and does nothing (unlike the original `rotated &= ~c;`).
Dippo, your observations is interesting.
It is very obvious that something strange is going on...
For your test code the implementation of toLowerAscii() should have nearly no
impact, as that operation is really trivial and gcc is smart.
Note that it is generally recommended to put all your
This works for me:
type
ConceptA = concept c
ConceptB = concept c
c.myProc(ConceptA)
Obj = object
proc myProc(obj: Obj, x: ConceptA) = discard
echo Obj is ConceptB #true
As for why, I'm not really sure as

Hey thanks for the help!
Here's what I had to do to get it to compile/work fully (using Nim 0.17.2).
proc genPGparameters(prime: int): (int, int, int, seq[int]) =
echo("generating parameters for P", prime)
let primes = [2, 3, 5, 7, 11, 13, 17, 19, 23]
var
Hello all,
Everybody here wants to make Nim the best language ever made. The question is
however, can we take code from other projects to use in Nim? The reason i am
asking this is because i found a website that contains allot of cool tricks to
make Nim faster. They are using the MIT license,
Hi woggioni,
the static code block is executed at compiletime inside the vm. you cannot
access the parameters outside the block. It´s out of scope. This is why you get
undecleared identifier. But indeed there should be a meaningful error message
instead of the compiler complain.
this works:
Hello,
I have detect two missing things in JS Backend.
First the method **removeEventListener**, that i have wrote taking
**addEventListener** as example:
proc removeEventListener*(et: EventTarget, ev: cstring, cb: proc(ev:
Event), useCapture: bool = false) {.importcpp.}
If you want to unpack the tuple you have to declare the resulting variables
first, like this:
proc foo(): (int, int, int) = (1,2,3)
static:
var a,b,c : int
(a,b,c) = foo()
echo a,b,c
what is quite strange is that this does not pass gcc
Hi jzakiya,
you simply can not use brackets within your constant-name. Here is the BNF
which literals are allowed:

As long as your tuple have
This should work
import math
proc genPGparameters(prime: int): (int, int, seq[int], int) =
echo("generating parameters for P", prime)
let primes = [2, 3, 5, 7, 11, 13, 17, 19, 23]
var modpg = 1
var excluded_primes = 0
for prm in primes:
I do `import math` to get `gcd` in my program, that's why you got that error.
I still can't get the output from `getPGparameters` assigned to constants of
the same names, to be used later in the program. I thought you could do
assignments like:
const (a, b, c) = tuple(x, y, z)
For Linux systems, this is how I do it in the [psutil
library](https://github.com/johnscillieri/psutil-nim):
proc cpu_count_logical*(): int =
## Return the number of logical CPUs in the system.
try:
return sysconf( SC_NPROCESSORS_ONLN )
except
Hi jzakiya, for me I will get: Error: undeclared identifier: 'gcd' (also when
you type the run-button below your code snippet).
