This makes the built-in 'eshell/cat' 5-10x faster on large files in my
(somewhat limited) tests. In addition, this change periodically
redisplays when using the Eshell buffered output so that users can see
some progress.
* lisp/eshell/esh-io.el (eshell-print-queue-size, eshell-print-queue,
eshell-print-queue-count): Make obsolete in favor of...
(eshell-buffered-print-size, eshell--buffered-print-queue)
(eshell--buffered-print-current-size): ... these.
(eshell-buffered-print-redisplay-throttle): New user option.
(eshell--buffered-print-next-redisplay): New variable.
(eshell-init-print-buffer): Make obsolete.
(eshell-flush): Add new REDISPLAY-NOW argument in favor of CLEAR (which
only 'eshell-init-print-buffer' should have used).
(eshell-buffered-print): Compare queued output length to
'eshell--buffered-print-current-size'.
(eshell-with-buffered-print): New macro.
* lisp/eshell/esh-var.el (eshell/env):
* lisp/eshell/em-dirs.el (eshell/cd):
* lisp/eshell/em-hist.el (eshell/history):
* lisp/eshell/em-unix.el (eshell/cat):
* lisp/eshell/em-ls.el (eshell/ls): Use 'eshell-with-buffered-print'.
(flush-func): Remove.
(eshell-ls--insert-directory, eshell-do-ls): Remove 'flush-func'.
* test/lisp/eshell/em-unix-tests.el (em-unix-test/compile/interactive)
(em-unix-test/compile/pipeline, em-unix-test/compile/subcommand): Fix
indentation.
(em-unix-test/cat/file-output): New test.
* etc/NEWS: Announce these improvements.
* lisp/eshell/eshell.el (eshell-read-command): Don't handle history
here.
* lisp/eshell/em-hist.el (eshell-hist-initialize): Properly set up
history for minibuffer.
(eshell-add-command-to-history): Immediately save history.
Erase all existing duplicates instead of just the last duplicate entry
when 'eshell-hist-ignoredups' is set to 'erase'. Multiple duplicates
can exist in case 'eshell-hist-ignoredups' was set to something else
than 'erase' in the past or if the history file contains duplicates
(bug#71107).
* lisp/eshell/em-hist.el (eshell-add-input-to-history): Remove all
duplicates from history ring.
* test/lisp/eshell/em-hist-tests.el
(em-hist-test/add-to-history/erase-existing-dups): New test.
* lisp/eshell/em-hist.el (eshell-history-append): New option.
(eshell--save-history): New function.
(eshell-hist-initialize):
(eshell-save-some-history): Replace eshell-write-history with
eshell--save-history, which respects the new option.
* doc/misc/eshell.texi (History): Document the change.
* etc/NEWS: Announce the change. (Bug#66700)
* lisp/eshell/em-hist.el (eshell-hist--new-items): New variable.
(eshell-hist-initialize): Initialize 'eshell-hist--new-items' to 0.
(eshell/history): Change the behavior of 'history -a' to "append new
history in current buffer to history file". Clarify the help text of
'history -r'.
(eshell-add-input-to-history): Increase counter of new history items.
(eshell-read-history): Respect 'eshell-hist-ignoredups' option.
(eshell-write-history): If the optional argument APPEND is non-nil,
appending new history items rather than the whole history.
* test/lisp/eshell/em-hist-tests.el (em-hist-test/history-append)
(em-hist-test/history-read): New tests (bug#66768).
* lisp/eshell/em-hist.el (eshell-add-input-to-history): Refactor to
use 'pcase' and correct the logic for the 'erase' case.
* test/lisp/eshell/em-hist-tests.el: Require our test helpers.
(eshell-write-readonly-history): Rename to...
(em-hist-test/write-readonly-history): ... this.
(em-hist-test/add-to-history/allow-dups)
(em-hist-test/add-to-history/no-consecutive-dups)
(em-hist-test/add-to-history/erase-dups): New tests (bug#63360).
* lisp/eshell/esh-util.el (eshell-redisplay): Make into obsolete
function alias for 'redisplay'. This removes a workaround for some
obscure bug apparently found in Emacs 21. Update all callers.
This isn't necessary and just makes unloading Eshell harder.
* lisp/eshell/em-banner.el:
* lisp/eshell/em-basic.el:
* lisp/eshell/em-cmpl.el:
* lisp/eshell/em-glob.el:
* lisp/eshell/em-prompt.el:
* lisp/eshell/em-rebind.el:
* lisp/eshell/em-smart.el:
* lisp/eshell/em-term.el:
* lisp/eshell/em-tramp.el:
* lisp/eshell/em-xtra.el:
Stop requiring 'eshell', and instead require specific subcomponents.
* lisp/eshell/em-hist.el: Stop requiring 'eshell' and 'em-pred'
(extension modules shouldn't require each other so they can be
independent).
(eshell-hist-parse-modifier): Ensure this can only be called when
'em-pred' is in use, and declare the relevant function.
* lisp/eshell/eshell.el (eshell-non-interactive-p): Move from here...
* lisp/eshell/esh-mode.el (eshell-non-interactive-p): ... to here.
Now that Eshell uses fields for its output, 'eshell-bol' is no longer
needed, and we can just use 'beginning-of-line'.
* lisp/eshell/esh-mode.el (eshell-bol): Mark obsolete.
(eshell-mode-map): Remove 'C-a' mapping.
(eshell-command-map): Use 'move-beginning-of-line'.
(eshell-move-argument, eshell-kill-input): Use 'beginning-of-line'.
(eshell-get-old-input): Remove unnecessary call to
'eshell-skip-prompt-function'.
* lisp/eshell/em-rebind.el (eshell-rebind-keys-alist): Remove 'C-a'
and '<home>' mappings; the global mapping for these
('move-beginning-of-line') does the same thing now.
* lisp/eshell/em-cmpl.el (eshell-complete-parse-arguments):
* lisp/eshell/em-elecslash.el (eshell-electric-forward-slash):
* lisp/eshell/em-hist.el (eshell-hist-word-reference)

* lisp/eshell/em-rebind.el (eshell-point-within-input-p):
* test/lisp/eshell/eshell-tests.el (eshell-test/forward-arg): Use
'beginning-of-line'.
* test/lisp/eshell/eshell-tests.el (eshell-test/run-old-command):
Rename to...
(eshell-test/get-old-input): ... this, and expand the test.
* lisp/eshell/em-hist.el (eshell/history): Use 'string-to-number'
instead of 'eshell-convert'.
* lisp/eshell/em-basic.el (eshell/umask): Simplify implementation and
be more careful about parsing numeric umasks to set.
* lisp/eshell/em-hist.el (eshell-hist--update-keymap): New function.
(eshell-hist-match-partial): Add :set property with above new
function.
(eshell-hist-mode-map): Update for eshell-hist-match-partial using
eshell-hist--update-keymap.
* lisp/emacs-lisp/seq.el (seq-subseq): Add autoload cookie.
* lisp/eshell/esh-util.el (eshell-sublist): Redefine using seq-subseq
and make obsolete. Update callers.
* lisp/wid-edit.el (widget-sublist): Redefine as obsolete function
alias for seq-subseq. Update callers.
* lisp/eshell/em-hist.el
(eshell-previous-matching-input-string-position): Both before and
within the while loop, n is always smaller than n (bug#43056).
Copyright-paperwork-exempt: yes
* lisp/eshell/esh-mode.el (eshell-mode-map, eshell-command-map): Set
up normal keymaps and prefix commands rather than re-initializing them
in each eshell buffer
* lisp/eshell/em-cmpl.el (eshell-cmpl-mode-map, eshell-cmpl-mode)
(eshell-cmpl-initialize):
* lisp/eshell/em-hist.el (eshell-hist-mode-map, eshell-hist-mode)

eshell-gather-process-output.
* lisp/eshell/esh-mode.el: Don't require esh-io nor esh-var, but
require esh-arg.
(eshell-directory-name): Move from eshell.el.
* lisp/eshell/esh-module.el: Don't require eshell.
* lisp/eshell/esh-opt.el: Don't require esh-ext at top-level.
(eshell--do-opts, eshell-show-usage): Require it here instead.

But don't require esh-mode.
(eshell-directory-name): Move to esh-mode.

file is nil.
- Prevent expansion of quick substitutions when the initial "^" is not
at start of line (Bug#29157).
- Allow spaces inside substitutions, so "^foo bar^baz" works.
- Allow trailing characters after substitution, so "^foo^bar^trailing"
works.
- Throw an error when substitution does not match.
* lisp/eshell/em-hist.el (eshell-expand-history-references): Expand
history substitution before other types of expansions, and expand them
with the whole line.
(eshell-history-substitution): New function to expand only
substitutions, taking in the entire typed line rather than individual
arguments.

History expansion is not so useful since interactive history commands
are already provided. It can produce surprising errors when the user
is not aware of the history designator syntax.
* lisp/eshell/em-hist.el (eshell-hist-initialize): Don't add
eshell-expand-history-references to eshell-expand-input-functions.
* etc/NEWS: Announce it.
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.
`eshell/clear' is implemented by sending a series of blank lines,
which is not a useful thing to have in the history.
* lisp/eshell/em-hist.el (eshell-input-filter-default): Use
`string-blank-p' which does check for newlines (even though newlines
have comment-end syntax, not whitespace syntax class).
* lisp/eshell/esh-mode.el (eshell/clear): Remove
`eshell-add-to-history' from `eshell-input-filter-functions' while
sending the blank lines. This change is needed to solve the bug if
the user customizes `eshell-input-filter' to something that doesn't
filter newlines.
