;;; Commentary:
|
||
|
||
;; This package defines TLA+ Major Mode to manipulate TLA+
|
||
;; specifications as invented by Leslie Lamport [1].
|
||
;;
|
||
;; Features:
|
||
;; - Syntax Highlighting for TLA+ Specification Files
|
||
;; - Running `SANY Syntactic Analyzer' on TLA+ files
|
||
;; - Exporting TLA+ Specification files with TLATeX to
|
||
;; DVI, PS or PDF files
|
||
;; - Inserting TLA+ Operators with an easy to use menu
|
||
;; or typical Emacs keystrokes.
|
||
;; - Use templates to generate Modules
|
||
;;
|
||
;; Installation:
|
||
;; To use tla+-mode, you have to load the tla+-mode.el file
|
||
;; with
|
||
;; (load "/path/to/tla+-mode.el")
|
||
;; and use it with
|
||
;; (require tla+-mode)

The parameter BUTTON is currently unused.

1. get the button at the current position of the `point'

2. get the text label of the button which is usually a line like

line XX, column YY

4. select the other-window (it is assumed that this is the *.tla

5. goto line and column.
