My period of disruptions is hopefully coming to an end, with this blog and our other websites now hosted on a different hardware (though the same VM), and the electrical work all finished and tidied up. So, I’ve been managing… Read moreLanguage tools progress
In my last post I said that I would leave discussion of the testing section of Wąsowski and Berger’s[1] chapter on code generation to a separate blog post, Basically because it is very tricky subject and deserves quite a bit… Read moreTesting DSLs and Code Generators
I recently came across the book, “Domain-Specific Languages: Effective Modeling, Automation, and Reuse” by Andrzej Wąsowski and Thorsten Berger[1], and this provides a very useful overview of current standard practice. The chapter on code generation is of particular interest, as… Read moreLooking at the Code Generation chapter of Wąsowski and Berger (2023)
In my previous post, Turning data into code, I described the latest iteration of my template language, used to convert data-structure or AST produced by the parser into source code in the target language. At that time, I was updating… Read moreTesting and then updating my template language
This week I’ve been working on support for my output template language in my on-line IDE. The IDE itself is basically a fairly old version of dock-spawn-ts, combined with Microsoft’s Monaco editor, with my own framework and configuration language. To… Read moreTurning data into code
One of the nice features of my early regular expression based parsers was that it was easy to get data out by defining sub-matches in the rules. For example, to match the start of a class (using PHP preg_match syntax,)… Read moreAdding named matches to parser rules
(For some background/context to this post see my Generative Programming page.) A slightly unusual aspect of my parser authoring tools is that there are three different levels of design involved. The classic parser writing tools, Lex and Yacc, separate to… Read moreEvolving a parser design strategy and tools
(For some background/context to this post see my Generative Programming page.) When I first started writing parsers for little source code generation languages, I largely ignored expressions because the simple declarative languages that I was creating had no need for… Read moreParsing expressions in little languages
