(Note that this README only discusses installation of Agda, not its standard library. See the Agda Wiki for information about the library.) * Using a binary package, prepared for your platform. Recommended if such a package exists. See the Agda Wiki. * Using stable packages available from Hackage. Install the prerequisites mentioned below, then run the following commands: cabal install Agda-executable agda-mode setup The second command tries to set up Emacs for use with Agda. As an alternative you can copy the following text to your .emacs file: (load-file (let ((coding-system-for-read 'utf-8)) (shell-command-to-string "agda-mode locate"))) * Using the source tar balls available from the Agda Wiki, or the development version of the code available from our darcs repository. 1) Install the prerequisites mentioned below. 2a) If your system is Unix-like you can now hopefully install the Agda 2 library, batch-mode tool and Emacs mode by running the following command: make install If this does not work on your system, or you want to have more control, you can follow 2b instead. 2b) Run the following commands in the top-level directory of the Agda source tree: cabal install agda-mode setup cd src/main cabal clean # To ensure recompilation when upgrading. cabal install The second command tries to set up Emacs for use with Agda. As an alternative you can copy the following text to your .emacs file: (load-file (let ((coding-system-for-read 'utf-8)) (shell-command-to-string "agda-mode locate"))) If you want to have more control over where files are installed then you can give various flags to cabal install, see cabal install --help. A section below lists an installation script which should work under the Ubuntu distribution of GNU/Linux, assuming that your configuration is reasonably standard. ------------------------------------------------------------------------ Configuring the Emacs mode ------------------------------------------------------------------------ If you want to you can customise the Emacs mode. Just start Emacs and type the following: M-x load-library RET agda2-mode RET M-x customize-group RET agda2 RET This is useful if you want to change the Agda search path, in which case you should change the agda2-include-dirs variable. If you want some specific settings for the Emacs mode you can add them to agda2-mode-hook. For instance, if you do not want to use the Agda input method (for writing various symbols like ∀≥ℕ→π⟦⟧) you can add the following to your .emacs: (add-hook 'agda2-mode-hook '(lambda () ; If you do not want to use any input method: (inactivate-input-method) ; If you want to use the X input method: (set-input-method "X") )) Note that, on some systems, the Emacs mode changes the default font of the current frame in order to enable many Unicode symbols to be displayed. This only works if the right fonts are available, though. If you want to turn off this feature, then you should customise the agda2-fontset-name variable. ------------------------------------------------------------------------ Prerequisites ------------------------------------------------------------------------ You need recent versions of the following programs/libraries: GHC: http://www.haskell.org/ghc/ cabal-install: http://www.haskell.org/cabal/ Alex: http://www.haskell.org/alex/ Happy: http://www.haskell.org/happy/ GNU Emacs: http://www.gnu.org/software/emacs/ haskell-mode: http://projects.haskell.org/haskellmode-emacs/ You should also make sure that programs installed by cabal-install are on your shell's search path. For instructions on installing a suitable version of Emacs under Windows, see below. Non-Windows users need to ensure that the development files for the C library zlib are installed (see http://zlib.net). Your package manager may be able to install these files for you. For instance, on Debian or Ubuntu it should suffice to run apt-get install zlib1g-dev as root to get the correct files installed. ------------------------------------------------------------------------ Installing a suitable version of Emacs under Windows ------------------------------------------------------------------------ Note that Agda code often uses mathematical and other symbols available from the Unicode character set. In order to be able to display these characters you may want to follow the procedure below when installing Emacs under Windows. 1. Install NTEmacs 22. Download from http://ntemacs.sourceforge.net/ the self-extracting executable ntemacs22-bin-20070819.exe When executed, it asks where to extract itself. This can be anywhere you like, but here we write the top directory for ntemacs as c:/pkg/ntemacs in the following. What follows is tested only on this version. Other versions may work but you have to figure out yourself how to use Unicode fonts on your version. 2. Install ucs-fonts and mule-fonts for emacs. Download from http://www.cl.cam.ac.uk/~mgk25/ucs-fonts.html the tar file http://www.cl.cam.ac.uk/~mgk25/download/ucs-fonts.tar.gz Let us write the top directory of extracted files as c:/pkg/ucs-fonts Next we create some derived fonts. cd c:/pkg/ucs-fonts/submission make all-bdfs This gives an error message about missing fonts, but ignore it. Download from http://www.meadowy.org/ the tar file http://www.meadowy.org/meadow/dists/3.00/packages/mule-fonts-1.0-4-pkg.tar.bz2 The untarred top directory is named "packages", but we are only interested in the subdirectory "packages/fonts". Let us assume we moved this subdirectory to c:/pkg/mule-fonts Add the following to your .emacs ;;;;;;;;; start of quoted elisp code (setq bdf-directory-list '( "c:/pkg/ucs-fonts/submission" "c:/pkg/mule-fonts/intlfonts" "c:/pkg/mule-fonts/efonts" "c:/pkg/mule-fonts/bitmap" "c:/pkg/mule-fonts/CDAC" "c:/pkg/mule-fonts/AkrutiFreeFonts" )) (setq w32-bdf-filename-alist (w32-find-bdf-fonts bdf-directory-list)) (create-fontset-from-fontset-spec "-*-fixed-Medium-r-Normal-*-15-*-*-*-c-*-fontset-bdf, ascii:-Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO8859-1, latin-iso8859-2:-*-Fixed-*-r-*-*-15-*-*-*-c-*-iso8859-2, latin-iso8859-3:-*-Fixed-*-r-*-*-15-*-*-*-c-*-iso8859-3, latin-iso8859-4:-*-Fixed-*-r-*-*-15-*-*-*-c-*-iso8859-4, cyrillic-iso8859-5:-*-Fixed-*-r-*-*-15-*-*-*-c-*-iso8859-5, greek-iso8859-7:-*-Fixed-*-r-*-*-15-*-*-*-c-*-iso8859-7, latin-iso8859-9:-*-Fixed-*-r-*-*-15-*-*-*-c-*-iso8859-9, mule-unicode-0100-24ff:-Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO10646-1, mule-unicode-2500-33ff:-Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO10646-1, mule-unicode-e000-ffff:-Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO10646-1, japanese-jisx0208:-JIS-Fixed-Medium-R-Normal--16-150-75-75-C-160-JISX0208.1983-0, japanese-jisx0208-1978:-Misc-Fixed-Medium-R-Normal--16-150-75-75-C-160-JISC6226.1978-0, japanese-jisx0212:-Misc-Fixed-Medium-R-Normal--16-150-75-75-C-160-JISX0212.1990-0, latin-jisx0201:-*-*-medium-r-normal-*-16-*-*-*-c-*-jisx0201*-*, katakana-jisx0201:-Sony-Fixed-Medium-R-Normal--16-120-100-100-C-80-JISX0201.1976-0, thai-tis620:-Misc-Fixed-Medium-R-Normal--24-240-72-72-C-120-TIS620.2529-1, lao:-Misc-Fixed-Medium-R-Normal--24-240-72-72-C-120-MuleLao-1, tibetan:-TibMdXA-fixed-medium-r-normal--16-160-72-72-m-160-MuleTibetan-0, tibetan-1-column:-TibMdXA-fixed-medium-r-normal--16-160-72-72-m-80-MuleTibetan-1, korean-ksc5601:-Daewoo-Mincho-Medium-R-Normal--16-120-100-100-C-160-KSC5601.1987-0, chinese-gb2312:-ISAS-Fangsong ti-Medium-R-Normal--16-160-72-72-c-160-GB2312.1980-0, chinese-cns11643-1:-HKU-Fixed-Medium-R-Normal--16-160-72-72-C-160-CNS11643.1992.1-0, chinese-big5-1:-ETen-Fixed-Medium-R-Normal--16-150-75-75-C-160-Big5.ETen-0, chinese-big5-2:-ETen-Fixed-Medium-R-Normal--16-150-75-75-C-160-Big5.ETen-0 " t) (setq font-encoding-alist (append '( ("JISX0208" (japanese-jisx0208 . 0)) ("JISX0212" (japanese-jisx0212 . 0)) ("CNS11643.1992.1-0" (chinese-cns11643-1 . 0)) ("GB2312" (chinese-gb2312 . 0)) ("KSC5601" (korean-ksc5601 . 0)) ("VISCII" (vietnamese-viscii-lower . 0)) ("MuleArabic-0" (arabic-digit . 0)) ("MuleArabic-1" (arabic-1-column . 0)) ("MuleArabic-2" (arabic-2-column . 0)) ("muleindian-1" (indian-1-column . 0)) ("muleindian-2" (indian-2-column . 0)) ("MuleTibetan-0" (tibetan . 0)) ("MuleTibetan-1" (tibetan-1-column . 0)) ) font-encoding-alist)) ;;;;;;; end of quoted elisp code To test the fonts, try M-x eval-expression RET (set-default-font "fontset-bdf") RET M-x view-hello-file You should see all the characters without white-boxes. ------------------------------------------------------------------------ Installation scripts for Ubuntu 9.10 ------------------------------------------------------------------------ Installs a released version: sudo apt-get install agda-mode agda-bin Installs the development version: sudo apt-get install ghc6 happy alex darcs emacs haskell-mode zlib1g-dev make wget http://www.haskell.org/cabal/release/cabal-install-0.6.4/cabal-install-0.6.4.tar.gz tar xzf cabal-install-0.6.4.tar.gz cd cabal-install-0.6.4 . bootstrap.sh cd .. $HOME/.cabal/bin/cabal update darcs get --lazy http://code.haskell.org/Agda cd Agda make CABAL_CMD="$HOME/.cabal/bin/cabal" install
