| 25 | ;;; Commentary: | |
| 26 | ||
| 27 | ;; This file defines backend network communication handlers for ERC. | |
| 28 | ;; | |
| 29 | ;; How things work: | |
| 30 | ;; | |
| 31 | ;; You define a new handler with `define-erc-response-handler'. This | |
| 32 | ;; defines a function, a corresponding hook variable, and populates a | |
| 33 | ;; global hash table `erc-server-responses' with a map from response | |
| 34 | ;; to hook variable. See the function documentation for more | |
| 35 | ;; information. | |
| 36 | ;; | |
| 37 | ;; Upon receiving a line from the server, `erc-parse-server-response' | |
| 38 | ;; is called on it. | |
| 39 | ;; | |
| 40 | ;; A line generally looks like: | |
| 41 | ;; | |
| 42 | ;; LINE := ':' SENDER ' ' COMMAND ' ' (COMMAND-ARGS ' ')* ':' CONTENTS | |
| 43 | ;; SENDER := Not ':' | ' ' | |
| 44 | ;; COMMAND := Not ':' | ' ' | |
| 45 | ;; COMMAND-ARGS := Not ':' | ' ' | |
| 46 | ;; | |
| 47 | ;; This gets parsed and stuffed into an `erc-response' struct. You | |
| 48 | ;; can access the fields of the struct with: | |
| 49 | ;; | |
| 50 | ;; COMMAND --- `erc-response.command' | |
| 51 | ;; COMMAND-ARGS --- `erc-response.command-args' | |
| 52 | ;; CONTENTS --- `erc-response.contents' | |
| 53 | ;; SENDER --- `erc-response.sender' | |
| 54 | ;; LINE --- `erc-response.unparsed' | |
| 55 | ;; | |
| 56 | ;; WARNING, WARNING!! | |
| 57 | ;; It's probably not a good idea to destructively modify the list | |
| 58 | ;; of command-args in your handlers, since other functions down the | |
| 59 | ;; line may well need to access the arguments too. | |
| 60 | ;; | |
| 61 | ;; That is, unless you're /absolutely/ sure that your handler doesn't | |
| 62 | ;; invoke some other function that needs to use COMMAND-ARGS, don't do | |
| 63 | ;; something like | |
| 64 | ;; | |
| 65 | ;; (while (erc-response.command-args parsed) | |
| 66 | ;; (let ((a (pop (erc-response.command-args parsed)))) | |
| 67 | ;; ...)) | |
| 68 | ;; | |
| 69 | ;; The parsed response is handed over to | |
| 70 | ;; `erc-handle-parsed-server-response', which checks whether it should | |
| 71 | ;; carry out duplicate suppression, and then runs `erc-call-hooks'. | |
| 72 | ;; `erc-call-hooks' retrieves the relevant hook variable from | |
| 73 | ;; `erc-server-responses' and runs it. | |
| 74 | ;; | |
| 75 | ;; Most handlers then destructure the parsed response in some way | |
| 76 | ;; (depending on what the handler is, the arguments have different | |
| 77 | ;; meanings), and generally display something, usually using | |
| 78 | ;; `erc-display-message'. | |
| 79 | ||
| 80 | ;;; TODO: | |
| 81 | ||
| 82 | ;; o Generalise the display-line code so that we can use it to | |
| 83 | ;; display the stuff we send, as well as the stuff we receive. | |
| 84 | ;; Then, move all display-related code into another backend-like | |
| 85 | ;; file, erc-display.el, say. | |
| 86 | ;; | |
| 87 | ;; o Clean up the handlers using new display code (has to be written | |
| 88 | ;; first). | |
