  • Appwrite - The Open Source Firebase alternative introduces iOS support
  • SonarLint - Clean code begins in your IDE with SonarLint
  • Scout APM - Less time debugging, more time building
  • TypeScript

    TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

    The situation I want to avoid is one which I've encountered in some hobby languages that I've tried, which is that any syntax error anywhere in the file causes the entire file to red squiggly. IMO, this is worse than nothing at all. TypeScript handles this problem very well; you can have multiple syntax errors in different places in the file, and each of them will report errors at a local scope. (I assume this has to do with balancing brackets, because unbalanced parenthesis seem like the easiest way to cause non-local syntax errors.) Problem is, at 9.5k lines of imperative code, trying to read the TypeScript parser hasn't made anything click for me.

  • bangalang

    I made a toy language awhile back that might help. It's mostly based on the "crafting interpreters" series but more functional (with types). There's a simple language server as well as a debugger. It's all in typescript. Github repo

  • Appwrite

    Appwrite - The Open Source Firebase alternative introduces iOS support . Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!

  • V8

    The official mirror of the V8 Git repository

    It must be a fairly large echo chamber since it has room for Clang, GCC, V8, OpenJDK, Roslyn, etc. (The Zend parser for PHP seems to use some flavor of YACC, but given PHP, I don't know if that strengthens or weakens my point.)

  • JDK

    JDK main-line development

    It must be a fairly large echo chamber since it has room for Clang, GCC, V8, OpenJDK, Roslyn, etc. (The Zend parser for PHP seems to use some flavor of YACC, but given PHP, I don't know if that strengthens or weakens my point.)

  • Roslyn

    The Roslyn .NET compiler provides C# and Visual Basic languages with rich code analysis APIs.
