🟢 Let's mojo build -D your="own" -D version=1 app.🔥 with 🛡️Constrained

Integrate apps with existing build scripts, for example

SIMD is a type, with methods and operators !

SIMD vectors are first-class citizens.

🔁 Python land and mojo land, PythonObject

note: need revision for better accessibility

🛣️ 🚌 multi-core (parallelize) with simd

simd and parallelize.

🪄 calling mojo functions from python

using pointers an ctype

🐍 using python in mojo: a to z

first steps and dancing

🏚️🏗️🏠 Moving owned values

__moveinit__ __del__ and many more !

📋 Traits: accept any types that comply to requirements

accept types based on some requirements

SIMD: 🔢✖️2️⃣🟰❪2️⃣,4️⃣,6️⃣,8️⃣❫

perform an operation on multiple numbers

👜 Variant, a type that can hold values of different types

The current type it holds can change and be checked

🐍🔍 type-checking a PythonObject

For example, to iterate python arrays that might contains objects of various classes

🧬 Parameters, Alias, Struct parameter deduction, more

Parameterize! (compile time meta-programming)

🪄🔮 Autotuned parametrized tests

Testing for multiple SIMD sizes

🔥 With blocks: with my_struct(1) as v

with blocks from struct (parametric/minimal/raise)

🏃 (SPEED) Parametric struct through CPU registers

the @register_passable decorator

🏞️ getattr: dynamic and static struct members

the_instance.method_not_defined() handled

🤹 making lists of structs with magic operators

unsafe references abilities until lifetimes

🫙 struct as a namespace (@staticmethod)

example: wrap python functions

🏳️ make test builds using a custom flag

mojo build program.mojo -D...

🕯️ reader.read[Int32,"swap"](3) in 45 lines

v0.4.0: powerfull magic

🔮 Autotune: optimization made easy

Easy to use

🔥 making compile time functions

Pointer[Int] of squared numbers

🧹 ASAP: will call __del__ when last used

when do del get called on instance

🏗️ moveinit 💿💿 copyinit 🐿️ non-destructing move

implement in struct: copy of instance, move, taking move

🤙 callbacks trough parameters

toy markdown generator as an example

🌊 256Hz: simd cosine and plot it

one cycle by vectorizing simd instructions, plot with python

🦜 env, argv and param_env (for alias)

arguments: command-line, env, alias

⌨️ introduction to types

syntax and concepts: not complicated

Try & Except: ✋->⚠️->⛑️->🩹->👍

raise custom errors and recover (with example)
