F. Jason Park	aedc8b55bf	Actually derive channel membership from PREFIX in ERC ... * lisp/erc/erc-backend.el (erc--with-isupport-data): Add comment for possibly superior alternate implementation. * lisp/erc/erc-common.el (erc--get-isupport-entry): Use helper to initialize traditional prefix slots in overridden well-known constructor. (erc--parsed-prefix): Reverse order of characters in the `letters' and `statuses' slots, in their defaults and also their definitions. (erc--strpos): New function, a utility for finding a single character in a string. * lisp/erc/erc.el (erc--define-channel-user-status-compat-getter): Modify to query advertised value for associated mode letter at runtime instead of baking it in. (erc-channel-user-voice, erc-channel-user-halfop, erc-channel-user-op, erc-channel-user-admin, erc-channel-user-owner): Supply second argument for fallback mode letter. (erc--cusr-status-p, erc--cusr-change-status): New functions for querying and modifying `erc-channel-user' statuses. (erc-send-input-line): Update speaker time in own nick's `erc-channel-member' entry. (erc-get-channel-membership-prefix): Adapt code to prefer advertised prefix for mode letter. (erc--parsed-prefix): Save "reversed" `letters' and `statuses' so that they're ordered from lowest to highest semantically. (erc--get-prefix-flag, erc--init-cusr-fallback-status, erc--compute-cusr-fallback-status): New functions for retrieving internal prefix values and massaging hard-coded traditional prefixes so they're compatible with existing `erc-channel-member' update code. (erc--partition-prefixed-names): New function, separated for testing and for conversion to a generic in the future when ERC supports extensions that list member rolls in a different format. (erc-channel-receive-names): Refactor to use new status-aware update and init workhorse functions for updating and initializing a `erc-channel-members' entry. (erc--create-current-channel-member): New "status-aware" function comprising the `addp' path of `erc-update-current-channel-member'. (erc--update-current-channel-member): New "status-aware" function comprising the "update" path of `erc-update-current-channel-member', which ran when an existing `erc-channel-members' entry for the queried nick was found. (erc-update-current-channel-member): Split code body into two constituent functions, both for readability and for usability, so callers can more explicitly request the desired operation in a "status-aware" manner. (erc--update-membership-prefix): Remove unused function, originally meant to be new in ERC 5.6. (erc--process-channel-modes): Call `erc--cusr-change-status' instead of `erc--update-membership-prefix'. (erc--shuffle-nuh-nickward): New utility function to ensure code like `erc--partition-prefixed-names' can use `erc--parse-nuh' in a practical and relatively convenient way in the near future. * test/lisp/erc/erc-scenarios-base-chan-modes.el (erc-scenarios-base-chan-modes--speaker-status): New test. * test/lisp/erc/erc-tests.el (erc--parsed-prefix): Reverse expected order of various slot values in `erc--parsed-prefix' objects. (erc--get-prefix-flag, erc--init-cusr-fallback-status, erc--compute-cusr-fallback-status, erc--cusr-status-p, erc--cusr-change-status): New tests. (erc--update-channel-modes, erc-process-input-line): Use newly available utilities imported from common library. * test/lisp/erc/resources/base/modes/speaker-status.eld: New file.

F. Jason Park	cca7956c82	Favor ISUPPORT params for MODE processing in ERC ... * etc/ERC-NEWS: Mention shift toward CHANMODES ISUPPORT parameter for dictating MODE parsing behavior. * lisp/erc/erc-backend.el (erc--init-channel-modes, erc--update-modes, erc-set-modes, erc-update-modes): Forward declarations, the last two being removals. (erc-server-MODE, erc-server-221): Use `erc--update-modes' instead of `erc-update-modes'. (erc-server-324): Use `erc--init-channel-modes' instead of `erc-set-modes'. * lisp/erc/erc-common.el (erc--channel-mode-types): New struct for stashing processed \"CHANMODES\" data for the current server. * lisp/erc/erc.el (erc-channel-modes): Fix doc string. (erc-set-initial-user-mode): Display a local notice when requesting redundant user MODE operations. (erc-set-modes, erc-parse-modes, erc-update-modes): Deprecate for reasons explained in associated ERC-NEWS entry. (erc--update-membership-prefix): New function, a helper for specifying arguments to the rather unruly `erc-update-current-channel-member'. (erc--channel-modes): New variable to record channel-mode state in a hash table. (erc--channel-mode-types): New variable and getter to stash and retrieve server-local instance of the struct of the same name. (erc--process-channel-modes): New function to parse channel-mode changes, dispatch handlers for unary modes, and update the local variables `erc-channel-modes' and `erc--channel-modes'. (erc--user-modes): New local variable for remembering user modes per server. New function of the same name, a "getter" for the variable. (erc--parse-user-modes): New function to parse user modes only. (erc--update-user-modes): New function to update and sort `erc--user-modes'. (erc--update-channel-modes): New function to replace much of `erc-update-modes', currently a thin wrapper around `erc--process-channel-modes' to ensure it updates status prefixes. (erc--update-modes): New function to call appropriate mode-updating function for the current buffer. (erc--init-channel-modes): New function to update channel mode letters without status prefixes. (erc--handle-channel-mode): New generic function, a placeholder for an eventual API to handle specific "unary" mode letters, meaning those that specify a single parameter for setting or unsetting. (erc-update-channel-limit): Update doc string and answer question posed by ancient comment. (erc-message-english-user-mode-redundant-add, erc-message-english-user-mode-redundant-drop): New English catalog messages. * test/lisp/erc/erc-scenarios-base-chan-modes.el: New file. * test/lisp/erc/erc-tests.el (erc-parse-modes, erc--update-channel-modes, erc--update-user-modes, erc--user-modes, erc--parse-user-modes): New tests. * test/lisp/erc/resources/base/modes/chan-changed.eld: New test data file.
