+**** Haskell
+ I have to use haskell in my new module, so there is now some haskell infra for that
+ first we have to set up a nix environment for our haskell tools
+ #+begin_src emacs-lisp :tangle emacsconfig/haskell.el
+ (setq haskell-env (nix-env-from-packages "Haskell"
+ "ghc"
+ "cabal-install"
+ "haskellPackages.fourmolu"))
+ #+end_src
+ Then haskell-mode setup, which integrates company mode as well as the sandbox
+ #+begin_src emacs-lisp :tangle emacsconfig/haskell.el
+ (use-package haskell-mode
+ :after nix-sandbox
+ :hook
+ (haskell-mode . set-haskell-company-backends)
+ (haskell-mode . company-mode)
+ (haskell-mode . haskell-indentation-mode)
+ :config
+ (setq haskell-process-wrapper-function
+ (lambda (args)
+ (cons
+ (nix-executable-find haskell-sandbox (car args))
+ (cdr args))))
+ (defun set-haskell-company-backends ()
+ (set (make-local-variable 'company-backends)

+ ormolu formats my haskell files, though I use fourmolu since I prefer prefixing chained infix functions
+ #+begin_src emacs-lisp :tangle emacsconfig/haskell.el
+ (use-package ormolu

+ :bind
+ (:map haskell-mode-map
+ ("C-c r" . ormolu-format-buffer)))
+ #+end_src
+ Finally, dante runs as background interpreter of my haskell codes and checks stuff for errors

**** Web stuff
I also have made some basic webpages. I haven't gotten too deep into JS with emacs yet, so this section
might expand later, but so far this is what I have
