2.7 Editing modes

Users of emacs can edit Asymptote code with the mode asy-mode, which is installed and enabled by default in the Debian package.

Particularly useful key bindings in this mode are C-c C-c, which compiles and displays the current buffer, and the key binding C-c ?, which shows the available function prototypes for the command at the cursor. For full functionality you should also install the Apache Software Foundation package two-mode-mode: http://www.dedasys.com/freesoftware/files/two-mode-mode.el

Fans of vim can customize vim for Asymptote with

cp @value{Datadir}/doc/asymptote/examples/asy.vim.gz ~/.vim/syntax/asy.vim.gz
gunzip ~/.vim/syntax/asy.vim.gz

and add the following to their ~/.vimrc file:

augroup filetypedetect
au BufNewFile,BufRead *.asy     setf asy
augroup END
filetype plugin on

If any of these directories or files don't exist, just create them. To set vim up to run the current asymptote script using :make just add to ~/.vim/ftplugin/asy.vim:

setlocal makeprg=asy\ %
setlocal errorformat=%f:\ %l.%c:\ %m
