Rho, Sigma and Other Fantastic Beasts of EO

Since the last blog post, we released a new version of EO where we got rid of the σ (Sigma) attribute. So, this blog post will try to explain all special attributes and assets such as Δ (Delta), φ (Phi), σ (Sigma), λ (Lambda), and ρ (Rho) as promised in one of the previous blog posts.

New Syntax for Nameless @-Bound-Only Objects

We’re continuing to observe the features of the latest release of EO, and today we’re talking about new syntax for nameless @-bound-only objects.

Bye, bye, bool!

After the previous blog post, one of the followers brought an interesting suggestion in our Telegram chat (join it btw). He proposed getting rid of the object bool and making if an object not an atom. And it was quite interesting. So we made a new release where we followed our follower’s proposal.

Big changes in 0.36.0

It’s been a while since our last blog post. All this time, we were working hard on fixing bugs, creating new objects, and improving EO in general. And here it is - release 0.36.0, which contains many new features. So, this blog post is a summary that highlights the most significant changes.

Recursive tuple and varargs

We’re continuing to observe new features of the latest release 0.34.1 of EO, and today we talk about new recursive implementation of tuple object and why we got rid of varargs in our language.

Covert EO to φ-calculus expression and back

In the recently released version 0.34.0, we have implemented several changes to EO. Today, we will discuss the conversion of EO to φ-calculus expression and vice versa.

$ Object

In the world of EO programming, the $ object acting as a syntax sugar that refers to the current abstract object it is used in. This seemingly simple yet powerful feature provides programmers with an elegant way to manipulate and access objects within their code, ultimately enhancing readability and ease of use. In this blog post, we will dive deep into the concept of the $ object and shed light on its practical applications through illustrative examples.

Comparison of 0.0 and -0.0

Due to the peculiarities of working with data in EO, an interesting quirk had been arising when comparing 0.0 and -0.0. The fact is that in EO, these two values were not considered equal until we made changes.

Until recently, the comparison of 0.0 and -0.0 in EO didn’t work like in other languages, but we changed that. This short blog post provides a simplified explanation of number encodings, how such comparison takes place in popular programming languages, and how we changed this comparison in EO to meet the standard.
