* Have Python mode cooperate asynchronously with Eldocscratch/python-eldoc-asyncJoão Távora2020-07-081-69/+119
| | | | | | | | | | | | | | | | | When combined with Flymake mode, which also adds a value to eldoc-documentation-functions, Python-mode users can now experiment with different eldoc-documentation-strategy values. Also, this shoulda allow us to write automatic tests for this particular Eldoc functionality. * lisp/progmodes/python.el (inferior-python-mode): Set coming-preoutput-filter-functions. (python--shell-output-filter-in-progress) (python--shell-output-filter-buffer): Rename from python- variant. (python-shell-output-filter): Rework to support async operation. (python-eldoc--get-doc-at-point): Rework to support async. (python-eldoc-function): Use callback.
* Shoosh warnings about obsolete eldoc-documentation-functionJoão Távora2020-07-082-17/+12
| | | | | | | * lisp/progmodes/cfengine.el (cfengine3-mode): Remove mention to obsolete eldoc-documentation-function. * lisp/progmodes/python.el (python-mode): Use with-no-warnings.
* Make more parts of Emacs use new Eldoc capabilitiesJoão Távora2020-07-084-37/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Elisp-mode was doing a lot of work that can now be delegated to Eldoc. 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. (emacs-lisp-mode): Put two elements in eldoc-documentation-functions. * lisp/emacs-lisp/eldoc.el (eldoc--eval-expression-setup): Setup new Elisp eldoc-documentation-functions. * lisp/progmodes/flymake.el (flymake-mode): Use flymake-eldoc-function. (flymake-eldoc-function): New function. (Package-Requires): Require eldoc 1.1.0 * lisp/descr-text.el (describe-char-eldoc): Recommend eldoc-documentation-functions. * lisp/progmodes/cfengine.el (cfengine3-documentation-function): Recommend eldoc-documentation-functions * lisp/progmodes/octave.el (inferior-octave-mode): Use eldoc-documentation-functions. * lisp/cedet/semantic/grammar.el (semantic--docstring-format-sym-doc): New function. (semantic-grammar-eldoc-get-macro-docstring): Adjust.
* Better handle asynchronous Eldoc sourcesJoão Távora2020-07-084-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (eldoc-documentation-default, eldoc-documentation-compose): Tweak docstring. (eldoc-documentation-enthusiast, eldoc-documentation-compose-eagerly): New functions. (eldoc-echo-area-use-multiline-p): Add new semantics. (eldoc--handle-docs): Handle some of eldoc-echo-area-use-multiline-p. (eldoc-doc-buffer): New command. (eldoc-prefer-doc-buffer): New defcustom. (eldoc--enthusiasm-curbing-timer): New variable. (eldoc-documentation-strategy): Rename from eldoc-documentation-function. (eldoc--supported-p): Use eldoc-documentation-strategy (eldoc-highlight-function-argument) (eldoc-argument-case, global-eldoc-mode) (turn-on-eldoc-mode): Mention eldoc-documentation-strategy. (eldoc-message-function): Mention eldoc--message. (eldoc-message): Made obsolete.

(eldoc-print-current-symbol-info): Rework with cl-labels. * doc/emacs/programs.texi (Lisp Doc): Mention eldoc-documentation-strategy. * doc/lispref/modes.texi (Major Mode Conventions): Mention eldoc-documentation-functions. * etc/NEWS: Mention eldoc-documentation-strategy.
