The black hole…
...my black hole...
A few weeks ago I wrote about Writing Tree-sitter grammars in BNF, introducing a new toy project, a utility to write grammars in a clean BNF notation and convert them to the Tree-Sitter JavaScript syntax. The project repository is on GitHub: ambs/tree-sitter-bnf-tools. Version 0.2.0 is out now. I introduced a couple of new sub-commands to […]
I’ve been using eXist-db for some years, mainly as the backbone of LeXmart, a tool for lexicographers, and that has been used for different projects, and the most prominent of which is Dicionário da Língua Portuguesa. eXist-db is a powerful native XML database with XQuery support, widely used in digital humanities, publishing, and other applications […]
If you keep up with my blog, you might remember a tutorial series on using Tree-sitter. At that time, I expressed my frustration on using it to write grammars, as they are expressed in JavaScript. But I ended up learning it, and for that, I invested some time in the tutorial. The tutorial example was […]
I spent my birthday afternoon in a hospital waiting room. Not because I was sick, but because my mother-in-law was. While waiting, I kept staring at the hospital dashboard, trying to understand how the average waiting time for a particular urgency level could show two hours, when there was already some persons who have been […]
I’m back to using a Mac at work after almost four years on Windows. It’s a nice relief—though honestly, still not as good as running Linux. Anyway, while setting up the Mac, I stumbled on what I’m calling a bug (because it is one) in the mouse and touch-pad settings. Both panes in the Settings […]
In the last months, I’ve been hearing about Agentic-AI. The hype is enormous. I decided to delve deeper and understand what exactly Agentic-AI is and its relevance in today’s world. As a first try, I went to Wikipedia, and found a very clear definition of Agentic-AI: Thus, agentic AI is a program that uses AI […]
As stated previously, Part #5 of this tutorial provides a brief overview of using Tree-Sitter from C#. This post continues from Part #4 and will add a Domain Object Model to the parser. It will not include many details specific to Tree-Sitter, as it will be more of a restructuring of our Rust code. Nevertheless, […]
Linguamática is a scientific journal created 16 years ago (2009) by Xavier Gómez Guinovart, José João Almeida, and me. It is a joint venture between the University of Vigo and the University of Minho. Our main goal was to create a forum where we could discuss Natural Language Processing in the languages we were studying. […]
I will get back to Rust to investigate more Tree-Sitter features, like cursors. But for my job, I might need to use Tree-Sitter from C#. So, I decided to write a post on how to do that, this time, from Windows. In the future, maybe I can look into how to do that with dotnet […]
Continuing with Rust, in this part of the tutorial we will improve the grammar with support for a few new things. One will be the support of literals and regular expressions for terminal symbols, and the second will be the support for the Kleene closures. Grammar Literals The first changes we will perform are to […]
