Matriad: A WIP Programming Language Made in Rust

The Matriad programming language

Prerequisites

  • Rust must be installed, version 1.60.0 or greater
    • Older versions of Rust may compile this code, but there are no guarantees, so it is recommended you use the latest version of Rust when compiling this program.
    • Installing cargo for rust is also recommended
    • You can install both cargo and the rust compiler with rustup
  • Git must be installed if you want to clone the source code

Cloning

  • Clone the source-code using git like so:

Execution

  • This language is still not complete to the point where it's usable, but I've implemented the lexer for the most part, and you can try it out! I assume you want to look at the interesting errors more than the output though, which is very boring to look at.
# Format for running the code to check your file
# Run it through cargo:
cargo run --release <source_file> | <source_file.mrd>

# Or build the executable and use it:
cargo build --release
cd ./target/release
# Run the file
./matriad <source_file> | <source_file.mrd>

Aim

This language aims to be a language that is:

  • Easy to learn and use
  • Performant and efficient
  • Almost, or equally powerful as Rust or C++
  • Fun to read and write
    • syntax sugar to help make code shorter, and easier to read
  • Feature complete
    • almost everything needed is implemented in the standard library
  • Versatile
    • A general purpose language
    • Object-oriented or partially functional programming both have good support

This compiler aims to be:

  • Simple to set up
  • Easy to use
  • Good at showing error / warnings and other messages
    • Compiler suggests fixes for common mistakes
  • Relatively fast at compiling source code
  • Hassle-free (no bugs)
  • Versatile
    • interpreted and compiled mode

Notes

  • This language is currently in a:
  • Stage of development where nothing is really certain
  • Non-usable, but compilable state
# git must be installed!
git clone https://github.com/dquat/Matriad.git

Cargo.toml

[package]
name    = "matriad"
version = "0.1.0"
edition = "2021"
# email = "user.some1@outlook.com"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
crossterm     = "0.23.0" # cross platform terminal-interaction library
unicode-width = "0.1.9" # library to test the width of unicode characters

[profile.release]
# Mess with `lto`, `codegen-units` and `panic` settings.
# They sometimes cause performance improvements when enabled or disabled

lto           = "fat" # link-time optimization, slow build time, and marginal peformance improvements
codegen-units = 1 # increases the performance marginally on my device?
# lowers size of file and may change performance but can cause problems with some libraries
panic         = "abort" # improves performance now?

Matriad: A WIP Programming Language Made in Rust

RUST on programming language

The title is a bit confusing to understand the context of the content. In this blog, I am going to run around and see the different aspects of programming language rust. And talk about the concepts that it introduces that are useful for various aspects of programming.

What is Rust?

Simply putting it is a statically as well as strongly typed programming language.

Let me explain:

_statically typed _indicates that all the datatypes that are expressed in the code are known at compile time and memory allocation is done properly.

Image for post

Then what is 👆 that? Let’s just say rust knows what you want to say.

But this doesn’t mean you could declare variables for a complex data type and expect rust to understand. Here comes the next point I mentioned above.

_strongly typed _indicates that the types are designed to make it harder to write syntatically incorrect code.

If you were to do even a little mistake with the syntax or definition of variables then the errors are caught at compile time. Not just the syntax errors but there are various tests build in the compiler to check for unused variablesdead code(Code that will never run), infinite loops as well as the lifetime of variables.

Serde Rust: Serialization Framework for Rust

Serde

*Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.*

You may be looking for:

Serde in action

Click to show Cargo.toml. Run this code in the playground.

[dependencies]

# The core APIs, including the Serialize and Deserialize traits. Always
# required when using Serde. The "derive" feature is only required when
# using #[derive(Serialize, Deserialize)] to make Serde work with structs
# and enums defined in your crate.
serde = { version = "1.0", features = ["derive"] }

# Each data format lives in its own crate; the sample code below uses JSON
# but you may be using a different one.
serde_json = "1.0"

 

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize, Debug)]
struct Point {
    x: i32,
    y: i32,
}

fn main() {
    let point = Point { x: 1, y: 2 };

    // Convert the Point to a JSON string.
    let serialized = serde_json::to_string(&point).unwrap();

    // Prints serialized = {"x":1,"y":2}
    println!("serialized = {}", serialized);

    // Convert the JSON string back to a Point.
    let deserialized: Point = serde_json::from_str(&serialized).unwrap();

    // Prints deserialized = Point { x: 1, y: 2 }
    println!("deserialized = {:?}", deserialized);
}

Getting help

Serde is one of the most widely used Rust libraries so any place that Rustaceans congregate will be able to help you out. For chat, consider trying the #rust-questions or #rust-beginners channels of the unofficial community Discord (invite: https://discord.gg/rust-lang-community), the #rust-usage or #beginners channels of the official Rust Project Discord (invite: https://discord.gg/rust-lang), or the #general stream in Zulip. For asynchronous, consider the [rust] tag on StackOverflow, the /r/rust subreddit which has a pinned weekly easy questions post, or the Rust Discourse forum. It's acceptable to file a support issue in this repo but they tend not to get as many eyes as any of the above and may get closed without a response after some time.

Introduction to Structured Query Language SQL pdf

SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.

Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:

1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.

2. Every database seller needs an approach to separate its item from others.

Right now, contrasts are noted where fitting.

OS in Rust: An executable that runs on bare metal

This is the very first blog of the series that pertains to create a basic Operating System using Rust Programming Language.

The aim of this series is to learn and understand the basics of Operating System. Through this series, you will get some ideas about the internal components of Operating System and how they interact with each other.

In this article, we will create a freestanding binary (an executable) that has the capability to run on bare metal. To create that executable we need to follow certain steps:

Steps to create a bare-metal executable:

  • Disable standard library
  • Define custom panic handler
  • Provide language items
  • Provide entry point
  • Build executable
