* lisp/progmodes/project.el (project-async-shell-command)
(project-shell-command): New commands to run 'async-shell-command'
and 'shell-command' in project's root directory.
(project-prefix-map): Bind commands to '!' and '&'.
* doc/emacs/maintaining.texi (Project File Commands): Document the
new commands.
* etc/NEWS: Announce the new commands.
* lisp/progmodes/project.el: Depend on xref. Bump the version.
* lisp/progmodes/xref.el: Remove 'project' from the list of
dependencies. Depending on Emacs 26.3 already ensures that some
version is available. Bump the version.
(xref--process-file-region): Move from project.el with a rename.
Update the sole caller.
(xref-backend-references): Make compatible with old project.el.
Update the docstring.
assoc-delete-all is not available for users who have installed
project.el via ELPA on older Emacs versions (bug#42668).
* lisp/progmodes/project.el
(project-remember-project, project--remove-from-project-list):
Replace assoc-delete-all with equivalent alternatives.
* lisp/progmodes/project.el (project-kill-buffer-conditions):
Replace the project-kill-buffers-ignores user option.
(project--kill-buffer-check): New function.
(project--buffers-to-kill): New function.
(project-kill-buffers): Use them. Add the NO-CONFIRM argument.
* lisp/progmodes/project.el (project--other-place-command):
Bind switch-to-buffer-obey-display-actions to t, so that
project-other-window-command and friends can affect
project-switch-to-buffer.
* lisp/progmodes/project.el (project-other-window-map,
project-other-frame-map, project--other-place-command,
project-other-window-command, project-other-frame-command,
project-other-tab-command): Add these functions and maps.
* lisp/progmodes/project.el: Bind project-other-window-command to C-x
4 p, project-other-frame-command to C-x 5 p and
project-other-tab-command to C-x t p (bug#42210).
* lisp/progmodes/project.el (project--read-project-buffer): New
function extracted from project-switch-buffer.
* lisp/progmodes/project.el (project-switch-buffer): Instead of
unconditionally reading a project buffer from the user, add
buffer-or-name argument, and populate it using
project--read-project-buffer when called interactively. Update
docstring.
* lisp/progmodes/project.el:
Add a longer description of the package and how to use it.
(project-prefix-map): Add entries for
'project-or-external-find-file' and
'project-or-external-find-regexp'.
* lisp/progmodes/project.el (project-find-functions)
(project-current, project-switch-to-buffer): Doc fix.
(project-current): Rename the argument DIR to DIRECTORY.
This reverts commit 9f9ce631a2.
It's still a bottleneck, but so are mapcar (with its effect on GC) and
concat. So our limits show in several places at once.
* lisp/progmodes/project.el (project-known-project-roots):
Rename from 'project-known-roots'. Update the docstring. Make
sure the returned value is a list of strings. Update the caller
(bug#41821).
* lisp/progmodes/project.el (project-kill-buffers-ignores):
Rename from project-kill-buffers-skip-conditions (bug#41868).
Update both references.
Add a :package-version attribute.
* lisp/progmodes/project.el (project-known-roots): New autoloaded function.
* lisp/vc/vc-hooks.el (vc-known-roots): New function.
* lisp/vc/vc.el (vc-root-diff, vc-print-root-log):
* lisp/vc/vc-dir.el (vc-dir): Use 'vc-known-roots' for default
values for read-directory-name.
* lisp/progmodes/project.el (project-shell): Improve docstring to
include information about an implementation detail.
* list/progmodes/project.el (project-eshell): Modelled after
'project-shell', change default behavior such that we don't create too
many eshell buffers by default. Use universal argument to create
subsequent buffers.
* lisp/progmodes/project.el (project-shell):
Pop to an existing shell buffer by default.
If there's none, or if universal argument is used, open a subsequent
shell buffer and jump to it. Prefix shell buffer name with the base
name of project root directory. (Bug#41858)
* lisp/progmodes/project.el
(project-switch-to-buffer): Pass the "other buffer" as DEF to
read-buffer if it belongs to the current project (bug#41879).
