From Programming Language Design (PLD) to Programmer Experience Design (PXD)This is a fork of another topic. I think it is high time that we stop talking about programming languages in isolation of the tools that support them. The tools have always depended on the languages, obviously, but increasingly the languages depend on the tools, especially in professional language design contexts. Dart and TypeScript are extreme examples of this where the type systems are there primarily to support tooling, and are much less about early error detection. As another example, C# design is heavily influenced by Visual Studio. Designing a language invariably involves trade offs, and if we accept tools as part of the core experience, we are able to make decisions that are impossible given the language by itself. For example, many people find type inference bad because it obscures developer documentation, especially if it is not completely local. However, given an editor where inferred type annotations are easily viewed when needed, this is no longer a problem. Likewise, a type system that cannot provide good comprehensible error messages in the tooling is fundamentally broken, but tooling can be enhanced to reach that point of comprehensibility. Type systems in general are heavily intertwined with tooling these days, playing a huge role in features like code completion that many developers refuse to live without. And of course, there are huge advances to be had when language and programming model design can complement the debugging experience. There are other alternative opinions about this, to quote and reply to Andreas from the other topic:
This is a good point: code should stand on its own as a human communication medium. However even our human communication is increasingly tool dependent, as we rely on things like the Google to extend our capabilities. We are becoming cyborgs whether we like it or not.
Code isn't bound to paper. Even when printed out on paper, it does not need to printed out as it was typed in.
This is more of an observation about current and future success of programming experiences. I would say it has already happened: successful programming languages already pay these costs, and new languages must either devote a lot of resources to tooling, or build them in at the beginning, or they simply won't be successful. Some people wonder why language X isn't successful, and then chalk it up to unenlightened developers...no.
Since an appeal to common sense is made, I would just think we have different world views. We at least exist in different markets. By Sean McDirmid at 2015-05-14 12:31 | LtU Forum | previous forum topic | next forum topic | other blogs | 19396 reads
