Forscape VS TypeScript

And if you like mathematical languages, you should check out Forscape :)

You can use the free GitHub runners to execute regression tests on Linux, Windows, and Mac. I recommend testing with 32bit compilation as well as 64bit- it has a way of smoking out bugs. You could take a look at the GitHub actions on my Forscape repo in the .github folder, although it's probably not the most idiomatic runner scripting, but it is a C++ project like yours.

When I was developing a typesetting text editor for Forscape, I struggled to get traction until stumbling on the following plan: 1) Implement the document data structure and get it rendering to the screen 2) Support non-mutating interactions, such as clicking to move the text cursor, selecting, copying, etcetera 3) Support mutating interactions, such as keyboard input, deleting, and pasting. You'll probably use the Command pattern to support undo/redo of mutations

The project is Forscape, although the language part is made a bit complicated because a goal of the project is creating an editor that supports typeset code with IDE interaction

Finally adding multi-file support to Forscape. The frontend UI aspects are completed and I'm quite happy with the result. The app is Unicode heavy and QString's UTF-16 encoding is an annoyance; I would much prefer if Qt relied on std::string even. But the signal/slot mechanism lets you achieve some complicated behaviour with minimal complexity, and Qt looks great.

Here's an example from a project. The first step installs Qt, the second step clones my repo on the runner, then a bit more setup with Conan, then building and running.

I've been working on the Key CAS project (Imgur Screenshot), CAS being an acronym for Computer Algebra System, and "Key" a judiciously chosen title. This was my third time attempting CAS- this iteration was a huge improvement, but I still find it to be a damn hard problem. The GUI comes from the open source project Forscape, a scientific computing environment written in C++.

It gets fun when you go beyond flat symbols and start supporting 2D notation, like fractions and matrices. Probably not worth the hassle for most things, but I think it makes matrix expressions more compact with better readability.

I've been working on a mathematical programming language, Forscape. Currently it's entirely numerical, but I'm building a CAS separately which I hope to use in the language.

Forscape is a scientific computing language in development. It supports first-class matrices and common matrix operations. The language reached a milestone when it achieved similar performance to other prominent scientific langs on a computationally involved numerical problem from my graduate school years. At this point, I am unsure where the development should go next and I would appreciate advice. What do you find missing in scientific computing languages? What are essential features that you need/enjoy?

Regular expressions are part of the language, so it's not so unreasonable that TypeScript should parse them and take their semantics into account. Indeed, TypeScript 5.5 will include [new support for syntax checking of regular expressions](https://github.com/microsoft/TypeScript/pull/55600), and presumably they'll eventually be able to solve the problem the GP highlighted on top of those foundations.

Dedicated syntax for creating unique subsets of a type that denote a particular refinement is a longstanding ask[2] - and very useful, we've experimented with implementations.[3]

I don't think it has any relation to runtime type checking at all. It's refinement types, [4] or newtypes[5] depending on the details and how you shape it.

Learning Curve and Developer Tooling sCrypt is an embedded Domain Specific Language (eDSL) based on TypeScript. It is strictly a subset of TypeScript, so all sCrypt code is valid TypeScript. TypeScript is chosen as the host language because it provides an easy, familiar language (JavaScript), but with type safety. There’s an abundance of learning materials available for TypeScript and thus sCrypt, including online tutorials, courses, documentation, and community support. This makes it relatively easy for beginners to start learning. It also has a vast ecosystem with numerous libraries and frameworks (e.g., React, Angular, Vue) that can simplify development and integration with Web2 applications.

As a JavaScript or TypeScript developer, you might have come across the terms type and interface when working with complex data structures or defining custom types. While both serve similar purposes, they have distinct characteristics that influence when to use them. In this blog post, we'll delve into the differences between types and interfaces in TypeScript, providing examples to aid your understanding.

TypeScript helps you in many ways in the context of a JavaScript app. It makes it easier to consume interfaces of any type.

In this guide, we'll be extracting information from Amazon product pages using the power of TypeScript in combination with the Cheerio and Crawlee libraries. We'll explore how to retrieve and extract detailed product data such as titles, prices, image URLs, and more from Amazon's vast marketplace. We'll also discuss handling potential blocking issues that may arise during the scraping process.
