When I read or hear about domain-specific languages in Julia I tend to cringe a little. In most cases it is not about a language, but rather an API. The difference? A DSL uses a syntax appropriate for its domain. An API is restricted by the syntax rules of the hosting language, in this case Julia.…

Parser generators do exist in the package community, See packages like [image] GitHub - chakravala/Reduce.jl: Symbolic parser for Julia language term... Symbolic parser for Julia language term rewriting using REDUCE algebra - GitHub - chakravala/Reduce.jl: Symbolic parser for Julia lang…

Following the theme of your DB examples, this Julia package seems to get very close to the syntax you want: https://github.com/wookay/Octo.jl

Do you mean we should embrace the two language issue instead of solving it…

The two language issue refers to having to use two different generic programming languages to properly balance ease of use and performance. In this case we’re talking about adding Domain Specific Languages to a generic programming language. Regular expressions are good example of a DSL embedded in …

[image] jandehaan: They both borrow from SQL, but can’t use the exact SQL syntax. As a result we have to learn multiple language dialects and remember how they differ from the SQL language standard. The idea of creating a language-specific API with the intention of imitating some imagined “ma…

Hello, From linked discussion by waldyrious it seems that the way to go on making own DSL is to create own REPL. On the other hand I read in https://github.com/JuliaLang/julia/pull/24945#issuecomment-349739529 that “REPL code will be considered non-public and unstable in 1.0”. Is there any canonic…

I have a package ReplMaker.jl which exposes a simpler API for building repl modes. It’s currently very basic and limited but for now, it’s still a nice option if one doesn’t want to deal with the difficult and confusing process of interfacing with the REPL standard library directly. If anyone out t…

Thanks Mason for your input and ReplMaker.jl. I’ve spotted your package from linked discussion. It is really interesting. It is so small that it is actually more robust (in terms of reducing deps) to include same logic in a package that would like to use ReplMaker. REPL standard library seems to be …

There are non standard string literals , which are not constrained to use julia syntax.
