The black hole…
Keeping up with the ANTLR tutorial, here goes a new issue. Part I and Part II are also available. As discussed previously, we are writing a conversion tool from the LOGO programming language into SVG. Up to now, we wrote a lot of code but did accomplish the generation of any SVG. In this issue […]
Continuing with the ANTLR tutorial, started in my last post, this second part advances with three main goals: Grammar Simplification The grammar presented in the last post was somewhat cucumbersome. The way we dealt with whitespace characters made the grammar difficult to read, as we needed to take care of where spaces could appear in […]
I’ve been working with Checkmarx for more than one and a half years, and I’ve been using ANTLR mostly daily. While there are some books on ANTLR, a couple of reference sites and some tutorials from the Strumenta site, I decided to write my own, with my vision of parsing and parsing writing in C#. […]
It’s been a long time since my last post here. It seems it gets less and less of a habit. It’s probably because I am not sure if someone reads my posts. Anyway, here goes a new one. Lately, I’ve been playing the game Tiny Room Stories: Town Mystery on my Android phone. Lately, I […]
I don’t write here for some time. It’s been a busy year. But a recent event makes me feel like it is an excellent time to write a little, about the architecture I created behind the Dicionário da Língua Portuguesa [Portuguese Language Dictionary] from Academia das Ciências de Lisboa [Lisbon’s Science Academy]. The story of […]
I was playing with GloVe, and noticed it does not ship with any code to run its pipeline. I suspect there are hundred of modules to do that from withing Python, but I decided to do a quick clean script to run that from the command line, and at the same time ready to tune […]
While some of this information is accurate, I have one main issue with this configuration: with Traefik running in non swarm mode, it is unable to detect containers running on other swarm nodes. 2021 March 14 In the last weeks I’ve been deploying a set of new services in three servers. As I want to […]
Today I took a long time, together with folks from the eXist-DB Community (thanks Luca Guariento and line0 for the brainstorming), to figure out why a function was receiving a node sequence instead of a single node. The question was why using this code was not working: And fn:lower-case was complaining for receiving a sequence […]
Today I stumped on how to create a XML document, storing it in a XQuery variable, that is composed from both a processing instruction and an XML body. While this might seem easy at first, creating the document as once: The truth is that this does not work. Nevertheless, there is a set of ways […]
I’ve been using eXist-DB for some time for the project of the Dicionário da Academia de Ciências de Lisboa, that is being revived from the PDF into TEI, so that a new digital version can be soon released. Recently I needed to update the server where eXist-DB was running, and decided to use a dockerized […]
