Regular Expression Engine for Mojo, any plans?
Do we have a regular expression engine implemented in Mojo?I haven't come across one yet, but it would be fantastic to have. Or is there a native solution planned for Mojo? If not, what could be our approach to developing one? I have no clue about the complexity involved in this task. Would we base it on some existing C engine or write it from scratch in Mojo. Thx
Why is this in-place operation not modifying the Python object in-place?
```mojo
from python import Python
def do_numpy_stuff(ar: PythonObject) -> PythonObject:
ar.iadd(3)...
Will mojo support JIT compilation?
From what I understand mojo does have already some JIT capabalities (like notebooks) but i'm talking about things like being able to pass run time variables to parameters (not arguments) in functions.
How to read args from environment
Hi, I am trying to write a simple program where I would read args from terminal and print them. I found this function in the documentation but well...there is no documentation https://docs.modular.com/mojo/stdlib/sys/arg/argv
I am wondering how is people learning to code in mojo considering documentation is at this level...
Will mojo upstream its borrow checker to llvm?
I understand mojo's borrow checker is built upon mlir, like everything in mojo, and I suspect you guys might have developed a lot of infrastructure that could benefit other projects using mlir. I wonder if mlir could include a standard dialect for doing borrow checking, and I think mojo could provide a great starting point. Would you mind sharing some details about how borrow-checking currently works internally?
Assigning slice of a tensor to a variable?
As best I can tell there is no direct way to assign a slice of a tensor to a new variable. I am looking for something Python-esque like
```
fn blah():
var t = Tensor[DType.float64](...
what can I really do with mojo at the moment?
Hi, I have been following Mojo since release but still haven’t seen any project i could use.
1. We always see mojo is meant to be used for ai but as far as i know there is no pytorch/flux or similar. So how would i be able to train my goof vector to sequence model? What would be the real diff vs using pytorch with cuda?
2. I have another usecase where i build high speed libraries with rust that scan over hashmaps in memory and provide ms response. Would mojo allow me to do something similar?...
mojo compiler implementation
What is the current implementation of the mojo compiler written in? Is there a plan for mojo to be self hosting? Is this why the compiler itself is not open source yet?
Passing a trait as a parameter to `Dict`?
This is related to a proposal for adding Middleware functionality to Lightbug HTTP: https://github.com/saviorand/lightbug_http/pull/33#issuecomment-2105547981
We're trying to do something like the following:
```
HTTPHandler is an interface for handling HTTP requests in the RouterMiddleware.
It is a leaf node in the middleware chain....
Printing at compile time
How to print at compile time? Something that looks like the following code, which currently does not compile:
```rust

What UnsafePointer can point to and allocate mem for?
I opened an issue last week in which I reported a problem with allocating for an array of Sets
https://github.com/modularml/mojo/issues/2503
This issue was closed as
not planned'which leaves me confused right now,. From the docu it says ...Classification on the Cloud
Instead of doing a custom GCP image hosting and Python image classifier. Is this something that the MAX Platform Supports? We are looking for a hosted classification system to train our models and then allow access to the model for classification.
What's the status of Mojo for compile-time validation?
It sounds like there's great stuff going on in Mojo to bring some of Rust's memory safety guarantees without as much conscious effort as Rust requires.
I'm curious about compiling a (well-annotated) Mojo program. To what extend Mojo does catch errors (type mismatches, say) on compile the way a statically typed language does? If that's not happening these days, does anybody know where that is on the roadmap?...
Trait `Comparable`
I looked around, but do not see an answer so far. Does Mojo have a Trait like
Comparable to indicate that a Struct has implemented all of the comparison dunder methods? Something like:
```mojo
trait Comparable:
# == equal
fn eq(self, other: Self) -> Bool: ......Mojo test
Did anyone get unit tests working?
I run
mojo test on the following folder structure:
```

Mojo and AWS.
How difficult is it to run Mojo apps in AWS, I intend to run an app in AWS ECS pointed to by API Gateway.

Return with move semantics
Is that possible to use the move semantic when returning a value from a function?
The code below would give error:
