* lisp/progmodes/project.el (project-files):
Remove (require 'xref).
(project--files-in-directory): Add it here instead.
(project-find-regexp, project-or-external-find-regexp): And here.
For 'xref--show-xrefs'.
* lisp/progmodes/xref.el (xref-matches-in-files): Extract from
project--find-regexp-in-files.
* lisp/dired-aux.el (dired-do-find-regexp): Also use it here.
* lisp/progmodes/project.el (project-try-vc): Do not treat a Git
submodule as a project root, go up to the parent repo.
(project--git-submodules): New function.
(project--vc-list-files): Use it. Recurse into submodules.
* lisp/progmodes/project.el (project-files): New method.
Implementation for VC projects that uses 'git ls-files' or 'hg
status --all' for listing. With gratitude to Tassilo Horn who has
done most of the legwork and wrote the first version of the code
(https://lists.gnu.org/archive/html/emacs-devel/2019-10/msg00069.html).
(project--vc-list-files): New function, to be used by the above.
(project--find-regexp-in-files):
Silence warnings about nonexistent files.
* lisp/progmodes/xref.el (xref--fetcher): New variable.
(xref--xref-buffer-mode-map): Add binding for 'g'.
(xref--revert-xref-buffer): New command.
(xref--show-xref-buffer): Accept a function as the first argument.
(xref--show-xrefs): Same.
(xref--find-xrefs): Pass the above a fetcher function.
* lisp/progmodes/project.el (project-find-regexp)
(project-or-external-find-regexp): Same.
* lisp/dired-aux.el (dired-do-find-regexp): Same.
To hopefully resolve a long-running discussion
(https://lists.gnu.org/archive/html/emacs-devel/2019-05/msg00162.html).
* lisp/progmodes/project.el (project-read-file-name-function):
New variable.
(project--read-file-absolute, project--read-file-cpd-relative):
New functions, possible values for the above.
(project-find-file-in): Use the introduced variable.
(project--completing-read-strict): Retain just the logic that fits
the name.
* lisp/progmodes/project.el (project-find-regexp): Don't pass
project's ignores to project--files-in-directory. The FILES glob
should be enough, and we don't want to prohibit searching inside
ignored directories this way (it can be counter-intuitive).
* lisp/progmodes/project.el (project--find-regexp-in-files):
Add an explicit '-e' before the pattern. Fixing the ability to
search for '--'. Reported by Juri Linkov <juri@linkov.net>.
* lisp/progmodes/project.el (project-ignores): Don't append the
default ignores list, just use vc-directory-exclusion-list.
(project--dir-ignores): Use the default ignores if the dir is
outside of the current project.
(project-files): Use project--dir-ignores to support external
roots better.
* lisp/progmodes/project.el (project--files-in-directory):
New function.
(project-files, project-find-regexp): Use it.
(project--dir-ignores): New function.
(project--find-regexp-in): Remove.
(project--process-file-region): New function.
(project--find-regexp-in-files): New function.
(project-find-regexp, project-or-external-find-regexp): Use it, and
project-files as well.
* lisp/progmodes/project.el (project-files): Move the actual
command building and invocation here.
(project-file-completion-table): Delegate to 'project-files'.
The main motivation for this change was the introduction of
project-query-replace. dired's multi-file query&replace was implemented
on top of etags.el even though it did not use TAGS in any way, so I moved
this generic multifile code into its own package, with a nicer interface,
and then used that in project.el.
* lisp/progmodes/project.el (project-files): New generic function.
(project-search, project-query-replace): New commands.
* lisp/dired-aux.el (dired-do-search, dired-do-query-replace-regexp):
Use multifile.el instead of etags.el.
* lisp/progmodes/etags.el: Remove redundant :groups.
(next-file-list): Remove var.
(tags-loop-revert-buffers): Make it an obsolete alias.
(next-file): Don't autoload (it can't do anything useful before some
other etags.el function setup the multifile operation).
(tags--all-files): New function, extracted from next-file.
(tags-next-file): Rename from next-file.
Rewrite using tags--all-files and multifile-next-file.
(next-file): Keep it as an obsolete alias.
(tags-loop-operate, tags-loop-scan): Mark as obsolete.
(tags--compat-files, tags--compat-initialize): New function.
(tags-loop-continue): Rewrite using multifile-continue. Mark as obsolete.
(tags--last-search-operate-function): New var.
(tags-search, tags-query-replace): Rewrite using multifile.el.
* lisp/emacs-lisp/generator.el (iter-end-of-sequence): Use 'define-error'.
(iter-make): New macro.
(iter-empty): New iterator.
* lisp/menu-bar.el (menu-bar-search-menu, menu-bar-replace-menu):
tags-loop-continue -> multifile-continue.
* lisp/progmodes/grep.el (lgrep, rgrep, grep-read-files): Explain
how to enter whitespace when using grep-read-files. (Bug#29303)
* lisp/progmodes/project.el (project-find-regexp): Likewise.
* lisp/vc/vc-git.el (vc-git-grep): Likewise.
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/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/project.el (project-roots): Implement for the
`transient' project type (bug#23224).
(project-current): Instead of signaling an error, return a
transient project instance rooted in the chosen directory.
* lisp/progmodes/project.el (project--completing-read-strict):
New function.
(project-find-file-in): Use it.
(project-file-completion-table): Move the default
implementation inside the cl-defgeneric form.
