The black hole…
...my black hole...
For this issue, I do not bring a lot of news. With Christmas and other requests, I had little time to continue this tutorial. But, having someone to test the previous issues of this tutorial (thanks, Vicente), we found out that the custom Build Task developed in the first parts of this tutorial has problems […]
Is this tutorial ever ending? Who knows. But while I am motivated for it, I will continue. I already have some ideas for future parts, so I can’t see this finishing before the ten or twelve issues. To start with, the news since the last part. I added documentation to the repository as well as […]
Things are getting exciting. I will introduce control statements in this part of the ANTLR tutorial, like repetitions and conditionals. For that, we will need to do a small walk, visiting the comparison and boolean operators. Then, we will be able to implement the control operators and, in the end, test everything. Comparisons LOGO does […]
Welcome back to my ANTLR tutorial. This part will be focused on the support of variables in LOGO. We will work on the assignment of values to variables and variables evaluation. We will also take the opportunity to split the grammar file into two: the lexer and the grammar parts. The previous parts of this […]
I am sure there are hundreds of better tutorials for GitHub actions. However, I decided that it would be nice to have tests run on every push to my repository of the code developed for my ANTLR Tutorial Series, and it seemed a good idea to document the process here. First, what are GitHub Actions? […]
This is the fifth part of my ANTLR Tutorial. You can look at the previous issues here: Part I, Part II, Part III, and Part IV. For this part, we will implement arithmetic expressions and mathematical functions (in fact, only a portion, as the remaining will be left as an exercise for the reader). To […]
This is the fourth part of my ANTLR Tutorial. Previous issues, Part I, Part II and Part III are also available. Before you ask, I have no idea how many parts this tutorial will have. I will keep sharing some knowledge, both from ANTLR and C#. I hope you keep enjoying it and that it […]
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#. […]
