Non-trivial parameter are not matched
What is the expected behaviour while matching parameters. Should they be structurally equal, or is some rewriting on their AST expected? For example, the following code gives the error on the return of doubleCube.
because
cannot implicitly convert 'SIMD[T, __lshift__(1, __add__(__sub__(N, 1), 1))]' value to 'SIMD[T, __lshift__(1, N)]' in return value
cannot implicitly convert 'SIMD[T, __lshift__(1, __add__(__sub__(N, 1), 1))]' value to 'SIMD[T, __lshift__(1, N)]' in return value
1<<((N-1)+1) is not considered equal to 1<<N which suggests threre is no rewriting of parameters. ...Type system does not recognize that a literal int is equal to an Int alias
I have a simple struct called Cube:
...
struct Cube[T: DType, N: Int]:
var value: SIMD[T, (1 << N)]
struct Cube[T: DType, N: Int]:
var value: SIMD[T, (1 << N)]
Does Mojo support virtual environments?
I use virtual environments in Python to isolate dependencies and ensure a consistent developer experience on projects. I was wondering if Mojo has a virtual environment tool or if it's compatible with Python's environment tools like
venv or conda environments?Cannot import Top level packages
Hi, I was trying to import a top level package, using built package, and without building but using filenames, but am not able to use it. I am sure as hell that I was able to do something like this in v0.3.x
Is this the expected behaviour, or something changed or am I missing something?
Let me know if you find out what's missing...

How to trigger `cf.assert` MLIR operations?
Suppose I have
...
let _ = __mlir_op.`cf.assert`[msg=__mlir_attr.`"ERROR"`](false)
let _ = __mlir_op.`cf.assert`[msg=__mlir_attr.`"ERROR"`](false)
Compile Mojo Python
Hey would there be ability to compile your package with Mojo and then pip install it on python without needing to install Mojo?
Build options - supported platforms
Hi! I know the SDK only supports linux right now, but does that also mean that you can only build for linux, and not for Windows/macOS yet?
Should we fuse Python's array class and mojo's DynamicVector's struct?
They are extremely similar.
Here is the documentation for array: https://docs.python.org/3/library/array.html
Here is the documentation for DynamicVector:

TOR-Client in Mojo
I would like to know whether there is already a tor client or how one can implement it so that the PE does not need any additional software to send data over the tor network. What important is that after compilation everything is in one without any third party software
randn not working
I am trying to use rand and randn functionality from the Mojo library https://docs.modular.com/mojo/stdlib/random/random.html#randn
rand works fine, but when trying to import randn I get:
error: package 'random' does not contain 'randn'

Cant install Mojo
I'm trying to install mojo and got the following error. can someone help me? this is my second time installing mojo, the problem caused while typing "modular install mojo"
Easy to install in offline enviroment, will mojo keep it and provide a package system ?
Recently I just tar entire .modular folder to another machine in our company, which is limit access internal only.
I found it's quite easy make it work , I skip venv/jupyter parts, just:
* modify mojo.cfg
* add some missing .so the my LIBRARY env . (machine has libtinfo.so.6, but no libtinfo.so, I don't know why )

External Python dependencies and Mojo binaries
I've just compiled a small Mojo program that uses Python iterop and the numpy library. Running the binary, everything works fine.
Hypothetically though, if I shared the binary with someone using the same os and hardware architecture as me, would they need to have Python and numpy installed (bare metal or virtualenv) to run the binary?
Or is the binary standalone?...
Will mojo let third parties handle the compiler distribution and packaging like python?
The cpython core team and steering council has the responsability of providing the source code but not to distribute it. It also doesn't have the responsability of defining how the packaging should be done.
This is a huge issue as third parties must implement tools to do this and there are many different tools now. Let's take for the installation:
- anaconda
- the py installer on windows from the windows store...
How to call function in share library

Const generics, a runtime or compile time construct?
https://docs.modular.com/mojo/changelog.html#v0.4.0-2023-10-05
Really happy to see this development in Mojo, where
StringLiteral is a const generic of type 'string', which is something not even C++ or Rust manages to do.
However, I am curious if the 'instantiation' or 'specialization' of the template parameter is actually resolved during runtime or compile time....Native in Windows of Mojo
When can I get an update of installation of Mojo in Windows Platform?
