2.7 Editing modes
Users of emacs can edit Asymptote code with the mode
asy-mode, after enabling it by putting the following lines in their
.emacs initialization file, replacing ASYDIR with the
location of the Asymptote system directory (by default,
/usr/local/share/asymptote or C:\Program Files\Asymptote
under MSDOS):
(add-to-list 'load-path "ASYDIR")
(autoload 'asy-mode "asy-mode.el" "Asymptote major mode." t)
(autoload 'lasy-mode "asy-mode.el" "hybrid Asymptote/Latex major mode." t)
(autoload 'asy-insinuate-latex "asy-mode.el" "Asymptote insinuate LaTeX." t)
(add-to-list 'auto-mode-alist '("\\.asy$" . asy-mode))
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:
Once installed, you can use the hybrid mode lasy-mode to edit a
LaTeX file containing embedded Asymptote code (see section LaTeX usage).
This mode can be enabled within latex-mode
with the key sequence M-x lasy-mode <RET>.
On UNIX systems, additional keywords will be generated from
all asy files in the space-separated list of directories
specified by the environment variable ASYMPTOTE_SITEDIR.
Further documentation of asy-mode is available within
emacs by pressing the sequence keys C-h f asy-mode <RET>.
Fans of vim can customize vim for Asymptote with
cp /usr/local/share/asymptote/asy.vim ~/.vim/syntax/asy.vim
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
Syntax highlighting support for the KDE editor Kate
can be enabled by running asy-kate.sh in the
/usr/local/share/asymptote directory and putting the generated
asymptote.xml file in ~/.kde/share/apps/katepart/syntax/.
