It took quite some time to read HOWTOs/compile/set up things etc., and the result was a bit underwhelming: Slow, using tons of memory, buggy, etc. Somehow this was to be expected from a new project, nevertheless it was a bit demotivating. Although it had a much smaller feature set, I was much more happy with Intero, it worked basically out-of-the-box. For most other IDEs, setting up a language mode is often just ticking a checkbox or pressing a button in an extension manager.</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Haskell does have langserver support, which means it's easy to have a <br>

Using the C++-LSP-Mode in Spacemacs takes a one-liner in the config ("Hey, please use clangd as the LSP backend") and an "apt install clangd" (if you don't have it already on your disk, which is very likely if you do development in C++ on Linux). I had a very different experience with Haskell and LSP.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">The more interesting question is: What's missing in the plugins for the <br>

Perhaps I should give haskell-language-server a new try, there seem to be precompiled binaries by now, and the Emacs Lisp part had quite a few fixes. Don't get me wrong: haskell-language-server is a great and important project, it's just that some months ago I wouldn't have recommended it to a newcomer. But this is a general problem in most Open Source projects: In their spare time, programmers like to program new features, not some packaging/deployment stuff, as important as the latter may be. This is probably only something for a person who gets paid to do this, and I'm not sure if there are such people in this project.</div></div></div>
