Cannot create a `DTypePointer` from `pointer<scalar<...>>`

how do I cast a pointer (btw, what is this? a MLIR type?) to a Pointer or preferably a DTypePointer? Inspired by this code,

``py
 out_arr.data = DTypePointer[dtype](
            __mlir_op.

pop.index_to_pointer

[
                _type : __mlir_type[

What is difference between `__init__(...) -> Self` vs `__init__(inout self, ...)`?

I'm familar with the later which is similar to what we typically write in Python. But what is the former one? It seems compile time with @register_passable structs always use that pattern.

Will Mojo be a multipurpose language?

I’ve seen this debate come up a few times now and I’d like to get an official reading on the question: “Is Mojo a multipurpose language or an AI specific language?” In other words: “Are the design features built with AI in mind or * focused on AI*?”

Core Library Conversions - What has/will been done?

Disclaimer: I'm kinda new to this; but I know python well enough to create dashboards for work and private. My objective is to assist with converting preexisting Python 3.10 libraries to Mojo using this daring project: https://github.com/msaelices/py2mojo...

Module loading error

I have a module with a following file structure as shown in the attached images. In the types folder there is an __init__.mojo file that imports the main type/function in the submodules for pretty importing by the user. The submodules similarly contain an _init_.mojo that imports the associated type/function so the main init can also cleanly import said type/function. This, however, is an issue according to Mojo. Attempting to compile this gives the following issue:...

Mojo Binary Sizes?

Are compiled binaries in mojo lighter in size compared to c, c++, or rust? I’m asking because I’m really interested in the embedded systems aspect of using this language and I’m curious on how lean it is.

Installing mojo in ubuntu only works with root

Hi, I am trying to install mojo in my ubuntu server following different guides and tutorials. I always see that people can install it in their home folder, but for me only works with root. I guess this is something related with my user permissions or configuration, rather than mojo, but I've already tried different workarounds and nothing works. Appreciate help, since having to run mojo as root all the time is a little bit inconvenient.

GitHub Actions/Runner - Mojo

I created a GH Action that would download and run Mojo here. Unfortunately, even after running modular clean, re-installing, using GITHUB_PATH, running in an Ubuntu container (cause the runners are just containers), and attempting to add mojo to the normal PATH both ways (bash and zsh) it still gives the error mojo: command not found. What am I missing?

Calling mktime from mojo

I'm trying to call C's mktime from mojo but I seem to get a negative number. Here's the code, is the external call correct? mktime returns a time_t which should be a positive int, but I see a negative value. https://github.com/sa-/mo-time/blob/02cf8d1ccdd92ab1ca0863f1538d342d48b18f59/mo_time/date_time.mojo#L73...
