The black hole…
...my black hole...
This is something we rarely see nowadays, with the noble exception of vinyl disks, for those who still like to hear a cracked sound from time to time. But in the old days, when cassettes were used, they were recorded on both sides. And if the first cassette I had for the ZX Spectrum +2 […]
A few nights ago, unable to sleep, I started thinking about old games and got reminded of the first game I ever played on my first computer, a ZX Spectrum +2 my father bought. The first cassette I ever used was for Jumping Jack. Very simple, no colors (well, I found out later that it […]
I am mostly a Linux user. That’s what I have in my personal laptop, and what I used for years, when in the Academia. Unfortunately, my change to the industrial world forced me to work with Windows, namely developing with C#. A few months ago, developing AI tools, That shift to Python allowed me to […]
I know that in the last weeks I have been posting too much about this tool, but I am having fun developing it, and I hope it gets useful for someone. Version 0.4.0 of tree-sitter-bnf-tools is out, and the headline this time is completeness: the BNF dialect now covers the full set of tree-sitter grammar-level […]
Here I am again sharing news from my recent toy-project. The version 0.3.0 of tree-sitter-bnf-tools is out. If you did not run my tree-sitter grammars in plain BNF notation instead of JavaScript. It hips a CLI called ts-bnf-tool to convert, check, format, and analyse those grammars. Versions 0.1.0 and 0.2.0 were covered in earlier posts; […]
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 […]
