Comment on I had to design a simple general purpose language for university, so I tried creating "ZoomerScript" with Jetbrains MPS

  Compiler courses are typically master level.

    My college must have been full of sadists. They had undergrad compiler courses and required students to take them.

    I had an entry-level compiler course during undergrad. We used JavaCC.

    Im having a compiler course on my 3rd year of (french) bachelor

      I definitely read this as you were a third year French major being forced to taking a compiler course for a moment and went wtf. Then my brain slapped itself and realized you mean you’re a student in France.

        Haha yeah I meant that I was studying computer science im France and not studying french

    It was part of my BSc, but that was over 20 years ago.

  Compilers are a specialized topic - and syntax design is fiddly - but it really is no harder than any other sort of program. A lot of the hard theoretical work was done back in the sixties and seventies. You don’t have to start from scratch. These days it’s “only” a matter of implementing the features you want and making sure your syntax doesn’t leave itself open to multiple interpretations. (just as arithmetic, e.g. ‘5 × 4 - 1’ requires some rules to make sure there’s only one correct interpretation, so do language syntaxes need to be unambiguous to parse. )

  Don’t get me wrong - writing a language is a lot of work and it’s super cool that OP has done this! I just want to stress that language development is 100% doable with an undergrad degree. If you understand recursion and how to parse a string you already have all the theory you need to get started.

    Valuable input! I actually am an undergrad student. There are a lot of frameworks out there that support writing languages, with MPS being one of them.

    If I’d start from scratch again and had a little more time, I’d frankly try writing an interpreter myself, instead of trying to conform to weird framework syntax, which I won’t be able to reuse in any other context.

    Saying syntax design is fiddly is an understatement. I focused very hard on getting an abstract syntax somehow finished before working on generation in my first iteration. Then I had so much technical debt, that I couldn’t get anything to work and had to rewrite a lot. So I scrapped it all and started again, starting with top level concepts including generation and only implementing some lower level ones, once everything around it worked properly.

  If you'd like to learn how, I recommend the book (which is also available online) Crafting Interpreters.

  Make a meme with no GitHub repo? Don’t sell yourself short.

  It’s likely transpiring and not compiling, so it’s a lot easier than it seems. Source: made a language that adds features to Python and transpiles to valid Python.

    It doesn’t compile or transpile in actuality. It generates Java based on an abstract syntax tree. The concrete syntax is not considered in Java generation by MPS.
