Vscode Haskell syntax highlighting color suddenly not working or missing

Asked 2022-Mar-15 at 22:12

My Haskell isn't showing any more syntax highlight and color, but I can still write it with suggestions and snippets. This is the first time it happened, and it works without a problem before, that it shows color and syntax highlighting

I've already tried uninstalling vscode and reinstalling again, installing GHCup again, and restarting my Mac. But still, I can't get the syntax color back. Tried changing the theme too, reinstalling Haskell related extension but nothing works.

Before this happen, I was reopening my vscode, and it pops out some message error on the right bottom, that says: "Error with calling Haskell server 3 times, so not calling again" or something along those lines, because I remember it only vaguely and now it doesn't reappear anymore.

How do I fix this syntax color highlighting issue with Haskell?

Why doesn't "n" downgrade my node version on a Mac?

Asked 2022-Feb-12 at 15:39

I’m using Mac Big Sur. I want to downgrade the version of Node. I tried the below (installing without sudo gives me permission errors) …

...

ANSWER

Answered 2021-Dec-13 at 20:34

The n message is telling you that the version it just "installed" and the version that is "active" are different. You have two versions of node installed, and the active version is the one that is first in the PATH.

The active version is /usr/local/opt/node@14/bin/node. I don't recognise that path, not sure what was used to install that. It must be in your PATH variable and there might be a clue in your login script as to what added /usr/local/opt/node@14/bin to the PATH?

To get the n installed version of node to be the active version, you could delete the other copy of node, or put /usr/local/bin earlier in PATH so it is found first, or simplest remove /usr/local/opt/node@14/bin from your PATH variable.

QUESTION

Compiling a library with a newer set of dependency in haskell

Asked 2022-Feb-11 at 22:48

Taking some not so old haskell project hdocs (last updated November 2020...).

If I build it with the original Stack file, everything is fine. And I can still build upon it on my own projects with the other libraries of that LTS which works well together. Reproducibl-ish build is good.

Now I want to update its dependencies

if I build it (after ghcup set ghc 9.0.2) with cabal v1-build I get nonsense about "fail backjumping" and "private dependencies"
If I either
- cabal v2-build (after ghcup set ghc 9.0.2) and let it think hard
- or if I build it using stack build

ANSWER

Answered 2022-Feb-11 at 22:48

According to the relevant section of the Cabal User Guide, Cabal provides a MIN_VERSION macro "for each package depended on via build-depends. The hdocs.cabal currently on GitHub only specifies haddock-library in the conditional parts of build-depends, so it would be missing for anything above GHC 8.10. That being so, if we are to keep the cabal file organised in the same way, this specific error can be avoided by specifying the missing dependencies for GHC 9.0:

ANSWER

Answered 2022-Jan-27 at 06:08

You installed Ruby previously with rbenv and now you show that you installed Ruby with brew, which is a totally different process. I assume you removed your rbenv installation, but left around some leftovers. If you wish to continue with your brew Ruby installation, which is in my opinion perfectly good, you just need to remove the rbenv leftovers by removing your /Users/oscar/.rbenv directory, possibly you may also need to restart your Terminal.

Judging by this issue on the ghcup repo (it cites the same error as yours), you are using WSL 1, which is not supported. You have to upgrade to WSL 2.

On Ubuntu, essentially all of the Haskell packages come in bland and -prof flavors. You need the latter for profiling.

ghcup is also fine. There's no need to purge it all -- ghcup and the package manager can coexist cleanly.

Even though there is the --lib flag, it's generally best to work under the assumption that Cabal doesn't do library installs. Never install a library, instead just depend on it – and have Cabal install, update etc. it whenever necessary.

But then how can you pass the necessary flags? With a cabal.project file.

Install ghcup

Choose one of the following installation methods.
Just place the ghcup shell script into your PATH anywhere.
Since this uses precompiled binaries you may run into several problems. You may run into problems with ncurses and missing libtinfo, in case your distribution doesn't use the legacy way of building ncurses and has no compatibility symlinks in place. Ask your distributor on how to solve this or try to compile from source via ghcup compile <version>. This was a bug in the build system of some GHC versions that lead to unconditionally enabled libnuma support. To mitigate this you might have to install the libnuma package of your distribution. See here for a discussion.
