  • Here is the reasoning:
  • 1. Compiler error is syntax error
  • 2. Language server can catch all syntax error
  • 3. Therefore, all compiler errors can be caught by language server
  • I have the feeling that this is true, based from my understanding on [Language Server Protocol - Wikipedia](https://en.wikipedia.org/wiki/Language_Server_Protocol). But the article doesn't explicitly mention any point of above.
  • If point 3 is true, then we can say that language server catches compiler error without having a compiler. And as the difference between an IDE and a code editor is just whether the compiler is integrated in it or not, then we can redefine IDE as a text editor with language server. Or we can say that as of today, code editor is IDE, and IDE is code editor, and we only need to use one term. The necessity for using the term IDE has ceased to exist. We only use it as a habit.

Can all compiler errors be caught by language server?
Here is the reasoning:
1. Compiler error is syntax error
2. Language server can catch all syntax error
3. Therefore, all compiler errors can be caught by language server

I have the feeling that this is true, based from my understanding on [Language Server Protocol - Wikipedia](https://en.wikipedia.org/wiki/Language_Server_Protocol). But the article doesn't explicitly mention any point of above.
