;; Major mode for editing Asymptote source code.
;; INSTALLATION:
;; Place this file (asy-mode.el) and asy-keywords.el in your Emacs load path.
;; Then choose ONE of the following installation methods:
;; * Method 1:
;; Copy and uncomment the following lines to your .emacs initialization file:
;;(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))
;; * Method 2:
;; Copy and uncomment the following line to your .emacs initialization file:
;;(require 'asy-mode)
;; Notes:
;;
;; For full functionality the two-mode-mode package should also be installed
;; (http://www.dedasys.com/freesoftware/files/two-mode-mode.el).
;;
;; See also paragraph II of the documentation below to automate asy-insinuate-latex.
;;; Code:
(defvar asy-mode-version "1.6")

"Emacs mode for editing Asymptote source code.
For full functionality the `two-mode-mode' package should also be installed
(http://www.dedasys.com/freesoftware/files/two-mode-mode.el).
I. This package provides two modes:
1- asy-mode:
All the files with the extension '.asy' are edited in this mode, which provides the following features:
* Syntax color highlighting;
* Compiling and viewing current buffer with the key binding C-c C-c;
* Moving cursor to the error by pressing the key F4.
* Showing the available function prototypes for the command at the cursor with the key binding C-c ?
* Compiling and viewing a TeX document linked with the current buffer (usually a document that includes the output picture).
To link a Tex document try 'M-x asy-set-master-tex' follow by C-Return (see descriptions further of the key binding C-Return, C-S-Return, M-Return, M-S-Return etc within 2- lasy-mode)
2- lasy-mode
Editing a TeX file that contains Asymptote code is facilitated with the hybrid mode 'lasy-mode'.
Toggle lasy-mode with M-x lasy-mode.
In this hybrid mode the major mode is LaTeX when the cursor is in LaTeX code and becomes asy-mode when the cursor is between '\\begin{asy}' and '\\end{asy}'.
All the features of asy-mode are provided and the key binding C-c C-c of asy-mode compiles and views only the code of the picture where the cursor is.
Note that some keys binding are added to the LaTeX-mode-map in lasy-mode if the value of the variable lasy-extra-key is t (the default)
.
* C-return: compile (if the buffer/file is modified) and view the PostScript output with sequence [latex->[asy->latex]->dvips]->PSviewer
* M-return: same with pdf output and with the sequence [pdflatex->[asy->pdflatex]]->PDFviewer
* C-M-return: same with pdf output and with the sequence [latex->[asy->latex]->dvips->ps2pdf]->PSviewer
* Add the Shift key to the sequence of keys to compile even if the file is not modified.
II. To add a menu bar in current 'latex-mode' buffer and activate hot keys, use 'M-x asy-insinuate-latex <RET>'.
You can automate this feature for all the 'latex-mode' buffers by inserting the five following lines in your .emacs initialization file:
(eval-after-load \"latex\"
'(progn
;; Add here your personal features for 'latex-mode':
(asy-insinuate-latex t) ;; Asymptote globally insinuates Latex.
))
You can access this help within Emacs by the key binding C-h f asy-mode <RET>
BUGS:
This package has been tested in:
* Linux Debian Etch
- GNU Emacs 22.0.50.1
- GNU Emacs 21.4.1 (only basic errors management and basic font-lock features within lasy-mode are supported)
* WindowsXP
- GNU Emacs 22.0.990.1 (i386-mingw-nt5.1.2600)
This package seems to work with XEmacs 21.4 but not all the features are available (in particular syntax highlighting).
Report bugs to http://asymptote.sourceforge.net
Some variables can be customized: M-x customize-group <RET> asymptote <RET>."
