| | | | | | | | | | | | | | | | As explained previously, we can't simply make eldoc-documentation-function an variable alias for eldoc-documentation-strategy, because ElDoc is pre-loaded in Emacs < 28, where it holds at least one buffer-local binding. So if eldoc.el is loaded in those versions, we do the variable alias binding in reverse. We do this using a macro eldoc--documentation-strategy-defcustom to at load time in which direction to make the variable alias. * lisp/emacs-lisp/eldoc.el (eldoc--documentation-strategy-defcustom): Helper macro. (eldoc-documentation-strategy, eldoc-documentation-function): Use it. (Version): Bump to 1.5.0

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When defining the obsolete variable alias for old eldoc-documentation-function (which now points to the newer eldoc-documentation-strategy), one gets the error "don't know how to make a localized vareiable an alias". I'm not sure, but I suspect this is because Eldoc is preloaded in Emacs 26.3 and the eldoc-documentation-function variable is already set locally by some Elisp buffer. Uninterning the symbol shortly before defining the alias seems to fix it. * lisp/emacs-lisp/eldoc.el (eldoc-documentation-function): Unintern on load. (Version): Bump to 1.3.0

* | Make more parts of Emacs use new Eldoc capabilitiesJoão Távora2020-07-087-78/+92

Flymake uses the new Eldoc functionality, too, installing a global documentation function that may report on diagnostics under point. CEDET's grammar.el was left as the only user of an Eldoc-internal function. That function was moved to grammar.el. That file is still, somewhat reprehensibly, using an internal function of elisp-mode.el, but this was left unchanged. In other situations, eldoc-documentation-functions is used or recommended. The only other places where the obsolete eldoc-documentation-function is still used is in libraries which are presumably meant to remain compatible with previous Emacs versions. * lisp/progmodes/elisp-mode.el (elisp-eldoc-funcall) (elisp-eldoc-var-docstring): New functions.

* | Better handle asynchronous Eldoc sourcesJoão Távora2020-07-086-93/+325
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a backward compatible redesign of significant parts of the eldoc.el library. Previously, Eldoc clients (major/minor modes setting its documentation gathering variables) needed to directly call eldoc-message, an internal function, to display the docstring to the user. When more asynchronous sources are involved, this is hard to do or even breaks down. Now, an Eldoc backend may return any non-nil, non-string value and call a callback afterwards. This restores power to Eldoc over how (and crucially also when) to display the docstrings to the user. Among other things, this fixes so called "doc blinking", or the very short-lived display of a lower priority Eldoc message. This would happen if a particular producer of documentation finishes shortly before a higher priority one, like in the LSP engine Eglot as reported by Andrii Kolomoiets <andreyk.mad@gmail.com> and Dmitry Gutov <dgutov@yandex.ru>. Gathering docstrings is now delegated to the variable eldoc-documentation-strategy, which is the new name for the now-obsolete eldoc-documentation-function, and still accepts the so-called "old protocol". Examples of the new strategies enabled are codified in functions such as eldoc-documentation-enthusiast, eldoc-documentation-compose-eagerly, along with the existing eldoc-documentation-compose and eldoc-documentation-default. The work of displaying and formatting docstrings is shifted almost fully to Eldoc itself and is delegated to the internal function eldoc--handle-docs. Among other improvements, it handles most of eldoc-echo-area-use-multiline-p and outputs documentation to a temporary *eldoc* buffer. The manual and NEWS are updated to mention the new Eldoc features. * lisp/emacs-lisp/eldoc.el (eldoc-documentation-functions): Overhaul docstring. (eldoc-documentation-compose, eldoc-documentation-default): Handle non-nil, non-string values of elements of eldoc-documentation-functions. Use eldoc--handle-multiline. (eldoc-print-current-symbol-info): Honour non-nil, non-string values returned by eldoc-documentation-callback. (eldoc--make-callback): Now also a function.

(byte-opt--arith-reduce, byte-optimize-minus, byte-optimize-1+) (byte-optimize-1-): Simplify: any number will do, and if N is a number, then so are -N, N+1 and N-1.
* | Remove long obsolete c-looking-at-bos. Make c-at-expression-start-p obsoleteAlan Mackenzie2020-07-041-11/+1
| | | | | | | | | | * lisp/progmodes/cc-engine.el (c-looking-at-bos): Remove. (c-at-expression-start-p): Make obsolete, with no alternative function.
* | Fix filling in js-mode and mhtml-mode (js-mode parts), fixing bug #41897Alan Mackenzie2020-07-042-13/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/progmodes/js.el (js-mode): Use "\\(?:" in the value of comment-start-skip rather than "\\(", fixing the second half of bug #41952. Call c-foreign-init-lit-pos-cache and install c-foreign-truncate-lit-pos-cache on before-change-functions, to connect up correctly with CC Mode's filling mechanism. * lisp/textmodes/mhtml-mode.el (mhtml--crucial-variable-prefix): Add prefixes "adaptive-fill-", "fill-", "normal-auto-fill-function" and "paragraph-" to pull in variables crucial to filling. (mhtml-syntax-propertize): Read the current submode from the piece of text being propertized rather than one character before it, and do so before erasing the submode text-property. (mhtml-mode): Set the js-mode value of auto-fill-function to js-do-auto-fill. Correctly initialize and use CC Mode's filling facilities, as above.
