### Prelude: Language Server Protocol
Language Server Protocol (LSP) is an attempt to simplify the code analysis feature in various IDEs. Before LSP, each individual IDE had to provide its own functionality for analyzing user code, and couldn't re-use the code analysis features of another IDE. Thus, for every IDE, for every language, a new code analyzer had to be developed. For \\(m\\) IDEs and \\(n\\) languages, there would need to be \\(m \times n\\) code analyzers. This is less than ideal. LSP solves this problem by moving the task of analyzing code into an external process, called a _Language Server_. The language server examines code, finds errors and warnings, and figures out the names of the various variables and functions that the source file contains. It then communicates this information to a _Language Client_, which is usually the IDE. The language client is responsible for presenting the information to the user in any way it deems fit.

Because LSP is a _protocol_, any server is able to communicate with any client. Once someone has written a language client for, say, Haskell, this client can be used by any IDE that supports LSP, which means that IDE instantly gains Haskell support. Similarly, once an IDE works as an LSP client, it can use any language server, and thus is immediately able to support all languages for which there is a language client.
