* * lisp/loadup.el: Load minibuffer after cl-genericStefan Monnier2019-10-273-10/+8
| | | | | | | | This is so minibuffer.el can make use of cl-generic * lisp/minibuffer.el (minibuffer-local-completion-map): Move switch-to-completions bindings here from... * lisp/simple.el (minibuffer-local-completion-map): ... here.
* time-stamp-time-zone: update customizationStephen Gildea2019-10-271-2/+18
| | | | | | | | | | | * time-stamp.el (time-stamp-time-zone): Support customization with an integer offset (a new possible value of the ZONE argument to format-time-string in Emacs 27). Update the safe-local-variable predicate from string-or-null-p (describing time-stamp-time-zone's domain before 2015) to new predicate time-stamp-zone-type-p (describing the current domain). * time-stamp-tests.el (time-stamp-test-helper-zone-type-p): New test.
* Fix point position after revert-buffer in tabulated-list modeEli Zaretskii2019-10-271-1/+6
| | | | | | | | | | | * lisp/emacs-lisp/tabulated-list.el (tabulated-list-print): Don't use count-screen-lines, as it is unreliable when lines are truncated and the region ends before a newline (the root cause is in vertical-motion, but is very hard to fix there). Instead, use vertical-motion directly, as the problems with counting/not counting the newline that ends the region are not relevant to what we need in this function, which is simply the number of the current window line. (Bug#37941)
* Optimize lisp/icomplete.el when default completion availableJoão Távora2019-10-271-4/+2
| | | | | | | | | | | | | | | | | | | | Often, when using icomplete with icomplete-show-matches-on-no-input and commands like C-h f, icomplete-exhibit will take a long time (like several seconds) to show all the completions. However, if there is a non-nil default value, like when the C-h f is performed exactly on a function name, the minibuffer prompt will reflect that immediately. If the user immediately presses RE (icomplete-force-complete-and-exit) we take that to mean "use the default" and avoid the long wait. As an extra performance tweak, this commit also removes an unneeded call to icomplete-exhibit in icomplete-minibuffer-setup. * lisp/icomplete.el (icomplete-force-complete-and-exit): Short-circuit possibility of non-nil minibuffer-default. (icomplete-minibuffer-setup): No need to explicitly icomplete-exhibit here since icomplete-post-command-hook will call it unconditionally.
* Expand rx definitions inside (not ...)Mattias Engdegård2019-10-271-0/+3

* Some Tramp trace improvementsMichael Albinus2019-10-271-2/+2
| | | | | | | * lisp/net/tramp.el (tramp-call-process): `result' can also be nil. * test/lisp/net/tramp-tests.el (tramp--test-timeout-handler): Improve trace format.
* Improve scoring algorithm for flex-style completionsJoão Távora2019-10-271-22/+38
| | | | | | | | | | | | | | | | | | | | The previous algorithm had two problems: it considered non-matches in the beginning and end of the string as matching "holes" and failed to penalize larger holes, making flex-score-match-tightness only effective in some corner cases. The new formula, which is described in code and in pseudo-code in the comments, fixes these problems. As a result, by default, C-h f flex now correctly bubbles up "company-search-flex-regexp" to the top, in front of "file-exists-p". With a flex-score-match-tightness smaller than 1.0, the situation is reversed. * lisp/minibuffer.el (flex-score-match-tightness): Adjust default value. Improve docstring example. (completion-pcm--hilit-commonality): Improve example. Remove unused variable. Improve algorithm.

* Restore default value of face completions-common-partJoão Távora2019-10-261-5/+6

* | Rework face hints for partial-string completion stylesJoão Távora2019-10-261-13/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't use completions-first-difference for the 'substring', 'flex' and 'partial-completion' styles, since there can be really no reasonable definition of a "first" difference there. Make completions-common-part inherit from 'underline' so that it is useful by default for all completion styles. * lisp/minibuffer.el (completions-common-part): Adjust description and change default value. (completions-first-difference): Ajust docstring. (completion-pcm--hilit-commonality): Don't use completions-first-difference.
* | Allow completion styles to adjust completion metadataJoão Távora2019-10-261-24/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit re-does the now-reverted commit with the same title. That version relied on generic functions, which cannot be used yet in files such as lisp/minibuffer.el. This version uses a symbol property completion--adjust-metadata instead. The new facility allows completion styles to have a say in metadata properties such as cycle-sort-function and display-sort-function. This is especially useful for completion styles such as 'flex', which generally produce many matches, including some potentially "obscure" ones. The default sorting strategy would often bubble the latter to the top of the list. The sorting function for 'flex' considers pre-computed matching scores and is thus much better than the default for this particular style. Additionally, it overrides the completion table's cycle-sort-function or display-sort-function properties if they exist, although it still uses them to pre-sort the result, so that they are still relevant for resolving ties. * lisp/minibuffer.el (completion--nth-completion) (completion--flex-adjust-metadata): New helper. (flex): Put completion--adjust-metadata property.
* | Revert "Allow completion styles to adjust completion metadata"João Távora2019-10-261-37/+9
| | | | | | | | | | | | | | | | | | Unbreaks the build. This reverts commit 7fc0292f5c49d11fc39853f8bc25586d54221e6a. Unfortunately, cl-defgeneric has some problems when used in lisp/minibuffer.el.
