Agda Installation |
Install the latest versions of cabal-install and of emacs via your
package manager, then open a
terminal and run the commands
cabal update
cabal install alex happy Agda
agda-mode setup
Note that even if your Linux distribution has an agda package
available it might not be recent
enough, so you should use the instructions above (in particular
Debian, Ubuntu, and Fedora all seem
to have outdated versions of Agda in their repositories).
Homebrew provides prebuilt packages for OS X. Install Homebrew and then run
brew install agda
agda-mode setup
Hopefully this should be all that is needed.
Download emacs from
[http://ftpmirror.gnu.org/emacs/windows/emacs-26/emacs-26.2-x86_64.zip]
and
unzip it somewhere (preserving the directory structure). You can now
run emacs with the
bin\runemacs.exe executable. Feel free to create a desktop shortcut to it.
Download and install the Haskell Platform from [https://www.haskell.org/platform/windows].
Open the Windows command prompt and run the following two commands. The second command will take a rather long time as it will compile Agda from scratch together will all of its dependencies.
cabal update
cabal install Agda
Create a file called .emacs (with the leading period) in the directory
C:\Users\##yourusername##\AppData\Roaming containing the following two lines
(load-file (let ((coding-system-for-read 'utf-8))
(shell-command-to-string "agda-mode locate")))
You can test your installation as follows.
Open Emacs and create a new file (File > Visit New File…) that you
name test.agda. You should see
(Agda) on the bottom of the window.
Type the text below in the file (type! do not copy-paste!).
postulate \bN : Set
As you type, the \bN should automatically change to a blackboard
bold N. If it turns to a box or
to something weird, there is something wrong with your fonts. Type
Ctrl-C followed by Ctrl-L, it
should now show (Agda:Checked) at the bottom of the buffer.
