26 | ;;; Commentary: | |
27 | ||
28 | ;; This file defines backend network communication handlers for ERC. | |
29 | ;; | |
30 | ;; How things work: | |
31 | ;; | |
32 | ;; You define a new handler with `define-erc-response-handler'. This | |
33 | ;; defines a function, a corresponding hook variable, and populates a | |
34 | ;; global hash table `erc-server-responses' with a map from response | |
35 | ;; to hook variable. See the function documentation for more | |
36 | ;; information. | |
37 | ;; | |
38 | ;; Upon receiving a line from the server, `erc-parse-server-response' | |
39 | ;; is called on it. | |
40 | ;; | |
41 | ;; A line generally looks like: | |
42 | ;; | |
43 | ;; LINE := ':' SENDER ' ' COMMAND ' ' (COMMAND-ARGS ' ')* ':' CONTENTS | |
44 | ;; SENDER := Not ':' | ' ' | |
45 | ;; COMMAND := Not ':' | ' ' | |
46 | ;; COMMAND-ARGS := Not ':' | ' ' | |
47 | ;; | |
48 | ;; This gets parsed and stuffed into an `erc-response' struct. You | |
49 | ;; can access the fields of the struct with: | |
50 | ;; | |
51 | ;; COMMAND --- `erc-response.command' | |
52 | ;; COMMAND-ARGS --- `erc-response.command-args' | |
53 | ;; CONTENTS --- `erc-response.contents' | |
54 | ;; SENDER --- `erc-response.sender' | |
55 | ;; LINE --- `erc-response.unparsed' | |
56 | ;; | |
57 | ;; WARNING, WARNING!! | |
58 | ;; It's probably not a good idea to destructively modify the list | |
59 | ;; of command-args in your handlers, since other functions down the | |
60 | ;; line may well need to access the arguments too. | |
61 | ;; | |
62 | ;; That is, unless you're /absolutely/ sure that your handler doesn't | |
63 | ;; invoke some other function that needs to use COMMAND-ARGS, don't do | |
64 | ;; something like | |
65 | ;; | |
66 | ;; (while (erc-response.command-args parsed) | |
67 | ;; (let ((a (pop (erc-response.command-args parsed)))) | |
68 | ;; ...)) | |
69 | ;; | |
70 | ;; The parsed response is handed over to | |
71 | ;; `erc-handle-parsed-server-response', which checks whether it should | |
72 | ;; carry out duplicate suppression, and then runs `erc-call-hooks'. | |
73 | ;; `erc-call-hooks' retrieves the relevant hook variable from | |
74 | ;; `erc-server-responses' and runs it. | |
75 | ;; | |
76 | ;; Most handlers then destructure the parsed response in some way | |
77 | ;; (depending on what the handler is, the arguments have different | |
78 | ;; meanings), and generally display something, usually using | |
79 | ;; `erc-display-message'. | |
80 | ||
81 | ;;; TODO: | |
82 | ||
f6b1b0a8 | 83 | ;; o Generalize the display-line code so that we can use it to |
597993cf MB |
84 | ;; display the stuff we send, as well as the stuff we receive. |
85 | ;; Then, move all display-related code into another backend-like | |
86 | ;; file, erc-display.el, say. | |
87 | ;; | |
88 | ;; o Clean up the handlers using new display code (has to be written | |
89 | ;; first). | |
90 | ||
91 | ;;; History: | |
92 | ||
93 | ;; 2004/05/10 -- Handler bodies taken out of erc.el and ported to new | |
94 | ;; interface. | |
