This is like xref-goto-xref, but quits the *xref* window just before
the user jump to ref.
* lisp/progmodes/xref.el (xref--show-location): Handle 'quit
value for SELECT.
(xref-goto-xref): Take optional QUIT arg.
(xref-quit-and-goto-xref): New command.
(xref--xref-buffer-mode-map): Bind "Q" and "TAB" to
xref-quit-and-goto-xref.
* doc/emacs/maintaining.texi (Xref Commands): Describe new bindings in
*xref*.
* etc/NEWS (Xref): Describe new binding.
When there is more than one xref to jump to, and an *xref* window
appears to help the user choose, the original intent to open a
definition in another window or frame is remembered when the choice to
go to or show a reference is finally made.
* lisp/progmodes/xref.el (xref--show-pos-in-buf): Rewrite.
(xref--original-window-intent): New variable.
(xref--original-window): Rename from xref--window and move up
here for clarity.
(xref--show-pos-in-buf): Rewrite. Don't take SELECT arg here.
(xref--show-location): Handle window selection decision here.
(xref--window): Rename to xref--original-window.
(xref-show-location-at-point): Don't attempt window management here.
(xref--show-xrefs): Ensure display-action intent is saved.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
* lisp/progmodes/grep.el (grep-mode-font-lock-keywords): Allow for NUL
characters following filename in grep context lines.
(grep--regexp-alist-column, grep--regexp-alist-bin-matcher)
(grep-with-null-regexp-alist, grep-fallback-regexp-alist): Remove.
(grep-regexp-alist): Recombine their contents here.
(grep-mode):
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-parse-tool-output-one-line):
* lisp/progmodes/xref.el (xref-collect-matches): Use the variable
`grep-regexp-alist' rather than the function.
* lisp/progmodes/grep.el (grep-use-null-filename-separator): New option.
(grep--regexp-alist-column, grep--regexp-alist-bin-matcher)
(grep-with-null-regexp-alist, grep-fallback-regexp-alist): New
constants, replacing `grep-regexp-alist'.
(grep-regex-alist): Mark the variable obsolete, add a new function of
the same name to replace it.
(grep-compute-defaults): Compute default for
`grep-use-null-filename-separator'.
(grep-mode): Set compilation-error-regexp-alist (buffer locally) to the
value of `grep-with-null-regexp-alist' or `grep-fallback-regexp-alist'
according to `grep-use-null-filename-separator'.
* lisp/progmodes/xref.el (xref-collect-matches): Call
`grep-regex-alist' instead of the obsolete variable. Don't hardcode
grep-regexp-alist match groups.
* etc/NEWS: Announce new use of --null. Move 'grep-save-buffers'
item under "Grep" heading as well.
* lisp/progmodes/xref.el (xref-collect-matches): Signal error
if find-grep returns a nonzero status (bug#23451). Remove the
comment: even if some output is present, a non-zero status
means something went wrong and it can't be relied upon.
* lisp/progmodes/xref.el (xref--regexp-syntax-dependent-p):
New function.
(xref--collect-matches): Use it. Don't try to enable the
appropriate major mode and file-local variables if the regexp
does not depend on the buffer's syntax (bug#26710).
(xref--collect-matches-1): Don't syntax-propertize in that
case either.
Pcase is macros, so these should have used eval-when-compile.
Anyway, pcase entry points are autoloaded, so the compiler handles it.
* lisp/profiler.el, lisp/emacs-lisp/eieio-core.el:
* lisp/emacs-lisp/generator.el, lisp/emacs-lisp/subr-x.el:
* lisp/progmodes/xref.el: No need to require pcase.
* lisp/progmodes/project.el (project-file-completion-table):
`shell-quote-argument' DIR as well.
* lisp/progmodes/xref.el (xref--rgrep-command): Pass DIR through
`shell-quote-argument' (bug#23453). Thanks for Kaushal Modi for
pointing out the problem. Assert that DIR doesn't start with `~'.
* lisp/progmodes/xref.el (xref-query-replace-in-results): Collect
all xrefs from the buffer first, then delegate most of the
processing to the value returned by xref--buf-pairs-iterator.
(xref--buf-pairs-iterator): New function. Return an "iterator"
which partitions returned markers into buffers, and only processes
markers from one buffer at a time. When an xref is out of date,
skip it with a message instead of signaling error (bug#23284).
(xref--outdated-p): Extract from xref--buf-pairs-iterator. Trim
CR from both strings before comparing.
(xref--query-replace-1): Remove the variable current-buf, no need
to track it anymore. Simplify the filter-predicate and search
functions accordingly. Iterate over buffer-markers pairs returned
by the iterator, and call `perform-replace' for each of them. Use
multi-query-replace-map (bug#23284). Use `switch-to-buffer' every
time after the first, in order not to jump between windows.
* test/automated/xref-tests.el
(xref--buf-pairs-iterator-groups-markers-by-buffers-1)
(xref--buf-pairs-iterator-groups-markers-by-buffers-2)
(xref--buf-pairs-iterator-cleans-up-markers): New tests.
* lisp/progmodes/xref.el (xref--collect-matches-1): Stop after one
match if re-search-forward doesn't move point (bug#23426).
* test/automated/xref-tests.el
(xref-collect-matches-finds-an-empty-line-regexp-match):
Uncomment test.
* lisp/progmodes/xref.el (xref-collect-references): Instead of
calling `semantic-symref-find-references-by-name', use
`semantic-symref-instantiate' and `semantic-symref-perform-search'
directly. Ask for `line-and-text' results (bug#23223).
(xref-collect-matches): Include the line text in the "hit"
structure.
(xref--convert-hits): New function, split off from
`xref-collect-references' and `xref-collect-matches', to convert
"hits" to xref instance list. Create a temporary buffer here, to
use it for post-processing all hit lines.
(xref--collect-matches): Use a different approach for non-visited
files. Insert the line text into the temp buffer, apply the
file's major mode the best we can without reading its whole
contents, syntax-propertize, and search in the result.
(xref--collect-matches-1): Extract, to handle the common logic
between two cases.
(xref--find-buffer-visiting): New function, a wrapper around
`find-buffer-visiting' to amortize its cost.
* lisp/cedet/semantic/symref/idutils.el
(semantic-symref-idutils--line-re): New constant.
(semantic-symref-parse-tool-output-one-line): Support result type
`line-and-text'.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep--line-re)
(semantic-symref-parse-tool-output-one-line): Same.
* lisp/cedet/semantic/symref/cscope.el
(semantic-symref-cscope--line-re)
(semantic-symref-parse-tool-output-one-line): Same.
* lisp/cedet/semantic/symref/global.el
(semantic-symref-global--line-re)
(semantic-symref-parse-tool-output-one-line): Same.
Now that the core workflow keeps the xref window visible, there's
less value in storing this history. And it never was
comprehensive enough to undo scrolling changes.
* lisp/progmodes/xref.el (xref--display-history)
(xref--save-to-history, xref-quit): Remove.
(xref--show-pos-in-buf): Update accordingly.
(xref--xref-buffer-mode-map): Remove xref-quit binding.
* lisp/progmodes/xref.el (xref--pop-to-location):
Rename WINDOW argument to ACTION.
(xref--with-dedicated-window): New macro.
(xref--show-pos-in-buf): Rename from `xref--display-position'.
Add and handle new argument, SELECTED. Use the above macro.
(xref--show-location): Add SELECTED argument.
(xref-show-location-at-point): Make an effort to avoid the
original window when showing the location.
(xref-goto-xref): Don't quit the xref window (bug#20487 and
http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg01133.html).
(xref--query-replace-1): Use xref--with-dedicated-window as well.
(xref--next-error-function): Call xref--show-location instead of
xref--pop-to-location.
(xref--show-xrefs): Rename WINDOW argument to DISPLAY-ACTION.
Only pass that value to xref--pop-to-location. Pass the current
selected window to xref-show-xrefs-function as the `window'
property.
(xref--find-xrefs, xref--find-definitions): Rename WINDOW argument
to DISPLAY-ACTION as well.
* lisp/progmodes/project.el (project-file-completion-table): New.
(project-find-file, project-or-external-find-file): Default to filename
at point.
(project-file-completion-table): New, split out from
project--find-file-in.
(project-find-file-in): Renamed from project--find-file-in, use
project-file-completion-table.
* lisp/progmodes/xref.el (ede-minor-mode): New declaration.
(xref--find-ignores-arguments): Add doc string.
* lisp/dired-aux.el (dired-do-find-regexp)
(dired-do-find-regexp-and-replace): New commands.
http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg00864.html
* lisp/dired.el (dired-mode-map): Change bindings for `A' and
`Q' to the new commands.
* lisp/progmodes/xref.el (xref-query-replace)
(xref-collect-matches): Add progress reporters.
(xref--find-ignores-arguments): Return nil for zero ignores.
(xref--show-xrefs): Add an optional argument.
(xref-collect-matches): Drop the assert. 'find' accepts a
regular file in place of directory argument, too.
* lisp/minibuffer.el (completion-category-defaults):
Add `project-file' category.
* lisp/progmodes/project.el (project-find-file)
(project-or-external-find-file): New commands.
(project--find-file-in): New private function.
* lisp/progmodes/xref.el (xref-collect-matches): Use
`expand-file-name' on DIR, to expand the tildes.
(xref--find-ignores-arguments): Extract from
`xref--rgrep-command'.
* lisp/progmodes/xref.el (xref-collect-matches): Undo
ill-advised change. The hits come in the order that `find'
produces them in, which isn't alphabetical.
* lisp/progmodes/project.el (project-library-roots): Rename to
project-external-roots.
(project-library-roots-function): Rename to
project-vc-external-roots-function. Only use it in the VC
backend, for now. Update project-external-roots accordingly.
(project-vc-library-roots): Remove.
(project-or-libraries-find-regexp):
Rename to project-or-external-find-regexp.
* lisp/progmodes/elisp-mode.el (elisp-library-roots):
Rename to elisp-load-path-roots.
* lisp/progmodes/etags.el (etags-library-roots): Remove. Use
an anonymous function for the default value of
project-vc-external-roots-function.
* lisp/progmodes/xref.el (xref-backend-functions): Move the
default value into a separate `add-hook' call (bug#21964).
* lisp/progmodes/elisp-mode.el (emacs-lisp-mode):
Don't declare the xref-backend-functions variable.
It doesn't make any difference.
