Previously, these were enabled/disabled at byte-compilation time, but
we want to control them at runtime.
* lisp/eshell/esh-cmd.el (eshell-eval-command): Call
'eshell-debug-command-start'.
(eshell-manipulate): Check 'eshell-debug-command' at runtime. Update
callers.
(eshell-debug-command): Move to "esh-util.el".
(eshell/eshell-debug, pcomplate/eshell-mode/eshell-debug): Move to
"em-basic.el".
(eshell-debug-show-parsed-args): Update implementation.
* lisp/eshell/esh-util.el (eshell-debug-command): Move from
"esh-cmd.el" and convert to a list.
(eshell-debug-command-buffer): New variable.
(eshell-condition-case): Check 'eshell-handle-errors' at runtime.
(eshell-debug-command-start): New function.
(eshell-debug-command): Move from "esh-cmd.el" and convert to a macro.
* lisp/eshell/em-basic.el (eshell/eshell-debug)
(pcomplete/eshell-mode/eshell-debug): Move from "esh-cmd.el" and
reimplement.
* lisp/eshell/eshell.el (eshell-command): Pass the original input to
'eshell-eval-command'.
* doc/misc/eshell.texi (Built-ins): Update documentation for
'eshell-debug'.
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.
* lisp/eshell/esh-var.el (eshell-get-variable):
* lisp/eshell/em-basic (eshell/echo): Don't use ':warning'; that's a
warning level, not a warning type.
* 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-basic.el (eshell/echo): Add -E option.
* lisp/eshell/esh-opt.el (eshell--process-option): Raise an error if
an unknown option is encountered, even when :external is nil.
* test/lisp/eshell/esh-opt-tests.el (esh-opt-process-args-test)
(test-eshell-eval-using-options): Add test cases for this.
* doc/misc/eshell.texi (Built-in commands): Expand on the
documentation of echo (bug#27361).
* lisp/eshell/em-basic.el (eshell-echo): Respect OUTPUT-NEWLINE even
when 'eshell-plain-echo-behavior' is non-nil.
(eshell/echo): Add "-N" option and recommend its use over "-n" in
Lisp-friendly echo.
(eshell/printnl): Simplify; 'eshell-stringify' is equivalent to
calling 'eshell-echo' here.
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.
Borrowing a trick from vc-sccs.el, wrap the defgroup in a progn
so that the whole thing ends up in the generated autoload file,
esh-groups.el.
* em-alias.el, em-banner.el, em-basic.el, em-cmpl.el, em-dirs.el:
* em-glob.el, em-hist.el, em-ls.el, em-pred.el, em-prompt.el:
* em-rebind.el, em-script.el, em-smart.el, em-term.el, em-unix.el:
* em-xtra.el: Replace eshell-defgroup with (progn (defgroup.
* eshell.el (eshell-defgroup): Remove alias.
