agda

install

Instructions from the cubical library Blogposts of myself: fedora 32 using WSL on windows (install agda from source, usually not what you want to do)

git clone --recurse-submodules https://github.com/agda/agda.git
cd agda
curl -sSL https://get.haskellstack.org/ | sh

or maybe 'stack upgrade' if already installed

stack install

test with 'agda', should return help

problems

stack install fails

  1. something with ghc

    there are multiple

    stack-VERSION_NUMBER.yaml
    

    files, try a specific one with

    stack install --stack-yaml stack-VERSION_NUMBER.yaml
    

setup ide

these are the two ide's for agda that worked for me.

emacs

find the installed 'agda-mode' and let it write something to .emacs with 'agda-mode setup' you might want to delete trailing whitespaces on save, by adding the following to your '.emacs':

  ;; delete trailing whitespace before saving in agda-mode
(defun agda-mode-delete-whitespace-before-save ()
  (when (eq major-mode 'agda2-mode)
    (delete-trailing-whitespace)))
(add-hook 'before-save-hook #'agda-mode-delete-whitespace-before-save)

vscode (this one is probably the right one for you, if you don't know emacs)

install vscode (it sends data home to Microsoft by default…) install vscode plugin https://marketplace.visualstudio.com/items?itemName=banacorn.agda-mode maybe, you want to tell vscode to kill trailing whitespaces and have exactly one newline at the end of each file by:

the default keymap for the mode has a lot of 'Ctrl+X …' in it, which prevented cut and paste from working properly. So I moved all the shortcuts to 'Ctrl+< …' which made 'Ctrl+X' for cutting work again.
