| 24 | ;;; Description: Run GNU Go in a buffer. |
| 25 | |
| 26 | ;;; Commentary: |
| 27 | |
| 28 | ;; This is an interface to GNU Go using the Go Text Protocol. Interaction |
| 29 | ;; with the gnugo subprocess is synchronous except for `gnugo-get-move'. This |
| 30 | ;; means you can use Emacs to do other things while gnugo is thinking about |
| 31 | ;; its move. (Actually, all interaction with the subprocess is inhibited |
| 32 | ;; during thinking time -- really, trying to distract your opponent is poor |
| 33 | ;; sportsmanship. :-) |
| 34 | ;; |
| 35 | ;; Customization is presently limited to `gnugo-animation-string', q.v. |
| 36 | ;; |
| 37 | ;; This code was tested with Emacs 20.7 on a monochrome 80x24 terminal. |
| 38 | |
| 39 | ;;; Code: |
| 40 | |
| 41 | (require 'cl) ; use the source luke! |

| 428 | ;; these properties: |
| 429 | ;; |
| 430 | ;; gnugo-full -- completely interpret the command string; the value is a |
| 431 | ;; func that takes the list of words derived from splitting the |
| 432 | ;; command string (minus the command) and handles everything. |
| 433 | ;; |
| 434 | ;; gnugo-rinse -- function taking raw output string and returning a |
| 435 | ;; (possibly filtered) replacement, the only one able |
| 436 | ;; to set the `gnugo-post-function' property (below). |
| 437 | ;; value may also be a list of such functions. |
| 438 | ;; |
| 439 | ;; gnugo-output -- symbol specifying the preferred output method. |
| 440 | ;; message -- show output in minibuffer |
| 441 | ;; discard -- sometimes you just don't care |
| 442 | ;; default is to switch to buffer "*gnugo command output*" |
| 443 | ;; if the output has a newline, otherwise use `message'. |
| 444 | ;; |
| 445 | ;; gnugo-post-function -- function or list of functions to call after the |
| 446 | ;; command (also after all output processing); only |
| 447 | ;; settable by a `gnugo-rinse' function. |
