+ * NEWS: Added text for pcomplete.el.
+
2000-10-16 Gerd Moellmann <gerd@gnu.org>
* 3B-MAXMEM, AIX.DUMP, SUN-SUPPORT: Removed.
*** gnus-mule.el is now just a compatibility layer over the built-in
Gnus facilities.
-*** pcomplete.el ??
+*** pcomplete.el is a library that provides programmable completion
+facilities for Emacs, similar to what zsh and tcsh offer. The main
+difference is that completion functions are written in Lisp, meaning
+they can be profiled, debugged, etc.
** Withdrawn packages
+2000-10-28 John Wiegley <johnw@gnu.org>
+
+ * textmodes/flyspell.el (flyspell-maybe-correct-transposition):
+ Changed this function to operate on a temporary buffer instead of
+ the main buffer. This not only keeps flyspell from marking a
+ buffer as changed that wasn't, but it solves the jumpy cursor
+ problem when attempts are made to edit incorrect words.
+ (flyspell-maybe-correct-doubling): Same change as for
+ `flyspell-maybe-correct-transposition'.
+
+ * calendar/timeclock.el (timeclock-log): Doc fix.
+ (timeclock-last-event): Doc fix.
+ (timeclock-log): Kill the timelog buffer after appending a new
+ event.
+ (timeclock-find-discrep): Use a temp buffer to read in the
+ timelog, instead of visiting the file.
+ (timeclock-log-data): A new function, along with a host of helper
+ functions, for the purpose of making timelog data accessible to
+ programmers.
+
+ * eshell/esh-mode.el (window-height test): Make certain that
+ `eshell-stringify-t' is non-nil.
+ (eshell-password-prompt-regexp): Changed to a much simpler
+ password regexp.
+ (eshell-send-input): If `eshell-invoke-directly' returns t,
+ directly invoke the parsed command using `eval'. This improves
+ turn-around time on simple commands by a factor of three or
+ greater, such as cd, ls, pwd, etc. -- which get used very often.
+ It also conserves thousands of cons cells per call (since
+ `eshell-do-eval' consumes memory like a Cookie Monster set loose
+ in the Pacific Cookie Company).
+
+ * eshell/esh-test.el (eshell-test): Whitespace fix.
+
+ * eshell/em-ls.el (eshell-ls-insert-directory): Make
+ `eshell-ls-initial-args' nil when inserting directory contents.
+
+ * eshell/em-script.el (eshell-script-initialize): Add names to
+ `eshell-complex-commands, since `source' and `.' are complex.
+
+ * eshell/esh-cmd.el (eshell-rewrite-for-command,
+ eshell-rewrite-while-command): Use `eshell-protect' instead of
+ `eshell-copy-handles'.
+ (eshell-rewrite-if-command): Use `eshell-protect' to wrap the call
+ bodies.
+ (eshell-separate-commands): Whitespace fix.
+ (eshell-complex-commands): Added a new list of names, for
+ determining whether a given command is as simple as it looks.
+ (eshell-invoke-directly): New function. Returns t if a command
+ should be invoked directly (using `eval'), rather than indirectly
+ using `eshell-do-eval'.
+ (eshell-do-eval): Whitespace fix.
+
+ * eshell/em-unix.el (eshell-default-target-is-dot): New variable,
+ which provides an emulation of the DOS shell behavior of assuming
+ that cp/mv/ln should copy/move/link to the current directory.
+ (eshell-remove-entries): Added a doc string.
+ (eshell-shuffle-files): Removed the check for `target' being null.
+ (eshell-mvcp-template, eshell-mvcpln-template): Renamed
+ `eshell-mvcp-template' to `eshell-mvcpln-template', and extended
+ it to do a smarter check of whether a destination was provided.
+ (eshell/mv, eshell/cp): Enable `:preserve-args'.
+ (eshell/ln): Enable `:preserve-args', and use
+ `eshell-mvcpln-template' to implement the body of the function.
+ (eshell/cat, eshell/make, eshell-poor-mans-grep, eshell-grep,
+ eshell/du, eshell/diff, eshell/locate): Stringify the argument
+ list after flattening it. This makes it possible to cat files
+ with numerical names.
+ (eshell-unix-initialize): Added several names to
+ `eshell-complex-commands.
+ (eshell-unix-command-complex-p): Return t if a given command name
+ may result in external processes being invoked.
+
+ * eshell/em-glob.el (eshell-glob-show-progress): Make this
+ variable nil by default, since it slows down glob processing by a
+ factor of two or more, and increases memory consumption.
+
+ * eshell/em-smart.el: Added a note about how memory consumptive
+ smart display mode can be (at least this is true in Emacs 21).
+ (eshell-smart-initialize): Whitespace fix.
+ (eshell-refresh-windows): Use `if' instead of `when'.
+ (eshell-smart-scroll-window): Calling `save-current-buffer' was
+ not necessary.
+ (eshell-currently-handling-window): Added a missing global
+ variable.
+
+ * eshell/em-ls.el (eshell-do-ls): Code simplification.
+ (eshell-ls-sort-entries, eshell-ls-entries, eshell-ls-dir):
+ Whitespace fix.
+ (eshell-ls-exclude-hidden): Added this variable in addition to
+ `eshell-ls-exclude-regexp'. This one prevents files beginning
+ with . from even being read, which can improve memory consumption
+ quite a bit.
+ (eshell-ls-dir): If `eshell-ls-exclude-hidden' is non-nil, do not
+ read file entries beginning with a dot. In home directories with
+ lots of hidden files, fully two-thirds of the time spent in ls is
+ used to read directory entries that are immediately thrown away.
+ (eshell-ls-initial-args): Added back this configuration variable,
+ for specifying default initial arguments to every call to ls.
+ Much faster than using an alias to do the same thing.
+ (eshell-do-ls): Use `eshell-ls-initial-args', if set.
+ (eshell-ls-dir): Whitespace change.
+
+ * eshell/em-dirs.el (eshell/pwd): Small code simplification.
+
+ * eshell/esh-util.el: Don't require `ange-ftp' if it's not
+ available.
+ (eshell-stringify-t): Added a customization variable, to indicate
+ whether `t' should be rendered as a string at all. If not, one
+ can still determine if the result of an expression is true using
+ "file-exists-p FILE && echo true".
+ (eshell-stringify): If `eshell-stringify-t' is nil, don't
+ stringify t!
+
+ * eshell/esh-module.el: Whitespace fix.
+
+ * eshell/em-alias.el (eshell-alias-initialize): Added
+ `eshell-command-aliased-p' to `eshell-complex-commands'.
+ (eshell-command-aliased-p): New function that returns t if a
+ command name names an aliased.
+
2000-10-29 Michael Kifer <kifer@cs.sunysb.edu>
* viper-cmd.el (viper-preserve-cursor-color): new test that avoids
* align.el, pcomplete.el, calendar/timeclock.el,
eshell/esh-module.el, eshell/eshell.el: Removed URL reference.
- * calendar/timeclock.el (timeclock-find-discrep): A fix to same
+ * calendar/timeclock.el (timeclock-find-discrep): A fix to some
faulty math, where holiday hours were being computing as seconds.

+A timelog contains data in the form of a single entry per line.
+Each entry has the form:
+
+ CODE YYYY/MM/DD HH:MM:SS [COMMENT]
+
+CODE is one of: b, h, i, o or O. COMMENT is optional when the code is
+i, o or O. The meanings of the codes are:
+
+ b Set the current time balance, or \"time debt\". Useful when
+ archiving old log data, when a debt must be carried forward.
+ The COMMENT here is the number of seconds of debt.
+
+ h Set the required working time for the given day. This must
+ be the first entry for that day. The COMMENT in this case is
+ the number of hours that must be worked. Floating point
+ amounts are allowed.
+
+ i Clock in. The COMMENT in this case should be the name of the
+ project worked on.
+
+ o Clock out. COMMENT is unnecessary, but can be used to provide
+ a description of how the period went, for example.
+
+ O Final clock out. Whatever project was being worked on, it is
+ now finished. Useful for creating summary reports.
+
+When this function is called, it will return a data structure with the
+following format:
+
+ (DEBT ENTRIES-BY-DAY ENTRIES-BY-PROJECT)
+
+DEBT is a floating point number representing the number of seconds
+\"owed\" before any work was done. For a new file (one without a 'b'
+entry), this is always zero.
+
+The two entries lists have similar formats. They are both alists,
+where the CAR is the index, and the CDR is a list of time entries.
+For ENTRIES-BY-DAY, the CAR is a textual date string, of the form
+YYYY/MM/DD. For ENTRIES-BY-PROJECT, it is the name of the project
+worked on, or t for the default project.
+
+The CDR for ENTRIES-BY-DAY is slightly different than for
+ENTRIES-BY-PROJECT. It has the following form:
+
+ (DAY-LENGTH TIME-ENTRIES...)
+
+For ENTRIES-BY-PROJECT, there is no DAY-LENGTH member. It is simply a
+list of TIME-ENTRIES. Note that if DAY-LENGTH is nil, it means
+whatever is the default should be used.
+
+A TIME-ENTRY is a recorded time interval. It has the following format
+\(although generally one does not have to manipulate these entries
+directly; see below):
+
+ (BEGIN-TIME END-TIME PROJECT [COMMENT] [FINAL-P])
+
+Anyway, suffice it to say there are a lot of structures. Typically
+the user is expected to manipulate to the day(s) or project(s) that he
+or she wants, at which point the following helper functions may be
+used:
+
+ timeclock-day-required
+ timeclock-day-length
+ timeclock-day-debt
+ timeclock-day-begin
+ timeclock-day-end
+ timeclock-day-span
+ timeclock-day-break
+ timeclock-day-projects
+
+ timeclock-day-list-required
+ timeclock-day-list-length
+ timeclock-day-list-debt
+ timeclock-day-list-begin

+ timeclock-entry-list-begin
+ timeclock-entry-list-end
+ timeclock-entry-list-span
+ timeclock-entry-list-break
+ timeclock-entry-list-projects
+
+A few comments should make the use of the above functions obvious:
+
+ `required' is the amount of time that must be spent during a day, or
+ sequence of days, in order to have no debt.
+
+ `length' is the actual amount of time that was spent.
+
+ `debt' is the difference between required time and length. A
+ negative debt signifies overtime.
+
+ `begin' is the earliest moment at which work began.
+
+ `end' is the final moment work was done.
+
+ `span' is the difference between begin and end.
+
+ `break' is the difference between span and length.
+
+ `project' is the project that was worked on, and `projects' is a
+ list of all the projects that were worked on during a given period.
+
+ `comment', where it applies, could mean anything.
+
+There are a few more functions available, for locating day and entry
+lists:
+
+ timeclock-day-alist LOG-DATA
+ timeclock-project-alist LOG-DATA
+ timeclock-current-debt LOG-DATA

@cindex Eshell, what it is

-Emacs itself. It also means that cooperation with other Lisp code is
-natural and seamless.

+What is a command shell? To properly understand the role of a shell,
it's necessary to visualize what a computer does for you. Basically, a
computer is a tool; in order to use that tool, you must tell it what to
do---or give it ``commands''. These commands take many forms, such as
one form of command input.
By far the most versatile way to express what you want the computer to
-do is using an abbreviated language, called @dfn{a script}. In a
-script, instead
-of telling the computer, ``list my files, please'', we write just
-``list''. In fact, this command is so commonly used that we abbreviate
-it to ``ls''. Typing @kbd{ls} in a command shell is a script way of
-telling the computer to list your files. This is comparable to viewing
-the contents of a folder using a graphical display.
-
-The real flexibility is apparent only when you realize that there are
-many, many ways to list your files. Perhaps you want them sorted by
-name, or sorted by date, or in reverse order, or grouped by type. Most
-graphical browsers have simple ways to express this. But what about
-showing only a few files, or only files that meet a certain criteria?
-In very complex and specific situations, the request becomes too
-difficult to express with a mouse. It is just these kinds of requests
-that are solvable using a command shell.

-@c Script is an extremely simplified language. Oddly enough, this
-@c actually makes it look more complicated than it is. Whereas normal
-@c languages can use many different embellishments, the form of a script
-@c command is always: a command verb, following by its arguments.
+@example
+ VERB [ARGUMENTS]
+@end example
-@c A verb? Arguments?
+The verb expresses what you want your computer to do. There are a fixed
+number of verbs, although this number is usually quite large. On the
+author's computer, it reaches almost 1400 in number. But of course,
+only a handful of these are really necessary.

-@c number of verbs, although this number is quite large. On my
-@c computer, it reaches almost 1400 in number! But of course, only a
-@c handful of these are necessary most of the time.
+Sometimes, the verb is all that's written. A verb is always a single
+word, usually related to the task it will perform. @command{reboot} is
+a good example. Entering that will cause your computer to reboot,
+assuming you have sufficient privileges.

-@c single word, usually related to the task it will perform.
-@c @command{reboot} is a good example. Entering that will cause your

+Other verbs require more information. These are usually very capable of
+verbs, and must be told more specifically what to do. This extra
+information is given in the form of arguments. Arguments are also
+single words, that appear after the verb. For example, @command{echo}
+is a command verb that prints back whatever you say. @command{echo}
+requires arguments, so that it knows what to echo. A proper use of

-@c echo This is an example of using echo!

+This piece of script expresses a command that causes the computer to
+print back: ``This is an example of using echo!''.
-@c This command would result in the computer printing back to you,
-@c ``This is an example of using echo!''. Pretty easy, no?
+Although command verbs always take the form of simple words, such as
+@command{reboot} and @command{echo}, arguments have a wide vaierty of
+forms. There are textual arguments, numerical arguments---even Lisp
+arguments. Distinguishing between these different types of arguments
+requires special typing, since the computer needs to know exactly what

-@c @item problem running "less" without argument on Windows
-@c Before running telnet, I noticed that 'less' (for example) was already
-@c configured as a visual command. So I invoked it from eshell to see what
-@c would happen.
-@c
-@c Here's the result in the eshell buffer:
-@c
-@c Spawning child process: invalid argument
-@c
-@c Also a new 'less' buffer was created with nothing in it .. (presumably this
-@c holds the output of less)
-@c
-@c If I run 'less.exe' from the eshell command line, I get the output I expect
-@c simply written to the buffer.

-@c @item Make M-5 eshell -> switch to *eshell<5>*, creating it if need be
-@c @item mv DIR FILE.tar does not remove directories

-@c If a script file, somewhere in the middle, does a "> /dev/null",
-@c output from all subsequent commands will be swallowed
-@c @item split up parsing of the text after a $ in eshell-var
-@c Similar to way that eshell-arg is structured. Then add parsing of
-@c $[?\n]
-@c @item after pressing M-RET, redisplay before running the next command
-@c @item argument predicates and modifiers should work anywhere in a path
-@c /usr/local/src/editors/vim $ vi **/CVS(/)/Root(.)
-@c Invalid regexp: "Unmatched ( or \\("
-@c
-@c with zsh, the glob above expands to all files named Root in
-@c directories named CVS.
-@c @item typing "echo ${locate locate}/bin<tab>" results in a Lisp error
-@c Perhaps it should interpolate all permutations, and make that the
-@c globbing result, since otherwise hitting return here will result in
-@c "(list of filenames)/bin", which is never very valuable. Thus, one
-@c could cat only c backup files by using "ls ${identity *.c}~". In that
-@c case, having an alias command name `glob' for `identity' would be
-@c useful
-@c @item for XEmacs on Win32, fix `file-name-all-completions'
-@c Make sure it returns directory names terminated by
-@c `directory-sep-char' (which is initialized to be ?/), rather than
-@c backslash
-@c @item once symbolic mode is supported for umask, implement chmod in Lisp
-@c @item create `eshell-expand-file-name'
-@c Which uses a data table to transform things like "~+", "...", etc
-@c @item abstract `eshell-smart.el' into `smart-scroll.el'
-@c It only really needs: to be hooked onto the output filter and the
-@c pre-command hook, and to have the input-end and input-start markers.
-@c And to know whether the last output group was "successful".
-@c @item allow for fully persisting the state of Eshell
-@c vars, history, buffer, input, dir stack, etc.
-@c @item implement D in the predicate list
-@c It means that files beginning with a dot should be included in the
-@c glob match
-@c @item a comma in a predicate list means OR
-@c @item error if a glob doesn't expand due to a predicate
-@c An error should be generated only if `eshell-error-if-no-glob' is
-@c non-nil
-@c @item the following doesn't cause an indent-according-to-mode to occur
-@c (+ RET SPC TAB
-@c @item create `eshell-auto-accumulate-list'
-@c It is a list of commands for which, if the user presses RET, the text
-@c gets staged as the next Eshell command, rather than being sent to the
-@c current interactive
-@c @item display file and line number if an error occurs in a script
-@c @item wait doesn't work with process ids at the moment
-@c @item enable the direct-to-process input code in eshell-term.el
-@c @item problem with repeating "echo ${find /tmp}"
-@c With smart display active, if I hold down RET, after a while it can't
-@c keep up anymore and starts outputting blank lines. It only happens if
-@c an asynchronous process is involved...
-@c
-@c I think the problem is that `eshell-send-input' is resetting the input
-@c target location, so that if the asynchronous process is not done by
-@c the time the next RET is received, the input processor thinks that the
-@c input is meant for the process; which, because smart display is
-@c enabled, will be the text of the last command line! That is a bug in
-@c itself.
-@c
-@c In holding down RET while an asynchronous process is running, there
-@c will be a point in between termination of the process, and the running
-@c of eshell-post-command-hook, which would cause `eshell-send-input' to
-@c call `eshell-copy-old-input', and then process that text as a command
-@c to be run after the process. Perhaps there should be a way of killing
-@c pending input between the death of the process, and the
-@c post-command-hook.
-@c @item allow for a more aggressive smart display mode
-@c Perhaps toggled by a command, that makes each output block a smart
-@c display block
-@c @item create more meta variables
-@c $! -- the reason for the failure of the last disk command, or the text
-@c of the last Lisp error
-@c
-@c $= -- a special associate array, which can take references of the form
-@c $=[REGEXP]. It also indexes into the directory ring
-@c @item eshell scripts can't execute in the background
-@c @item support zsh's "Parameter Expansion" syntax, i.e. ${NAME:-VAL}
-@c @item write an `info' alias that can take arguments
-@c So that the user can enter "info chmod"
-@c @item split off more generic code from Eshell
-@c parse-args.el --- parse a list of arguments
-@c interpolate.el --- interpolate $variable $(lisp)... references
-@c interp.el --- find which interpretor to run a script with
-@c sh-ring.el --- extend ring.el for persistant, searchable history
-@c zsh-glob.el --- zsh-style globbing and predicate/modifiers
-@c smartdisp.el --- smart scrolling in input buffers
-@c egetopt.el --- `eshell-eval-using-options'
-@c prompt.el --- code for outputting and navigating prompts
-@c cmd-rebind.el --- rebind certain keys in the input text
-@c unix.el --- provides Lispish UNIX command, such as unix-rm, etc.
-@c emacs-ls.el --- implementation of ls in Emacs Lisp
-@c texidoc.el
-@c pushd.el --- implementation of pushd/popd in Lisp
-@c interface.el -- a mode for reading command-line input from the user
-@c @item create a mode `eshell-browse'
-@c It would treat the Eshell buffer as a outline. Collapsing the outline
-@c hides all of the output text. Collapsing again would show only the
-@c first command run in each directory
-@c @item look through the Korn Shell book for feature ideas
-@c @item allow other version of a file to be referenced by "file{rev}"
-@c This would be expanded by `eshell-expand-file-name'
-@c @item print "You have new mail" when the "Mail" icon gets turned on
-@c @item implement M-|
-@c @item implement input redirection
-@c If it's a lisp function, input redirection implies "xargs" (in a
-@c way..). And if input redirection is added, don't forget to update the
-@c file-name-quote-list, and the delimiter list.
-@c @item allow #<WORD ARG> to be a generic syntax
-@c With the handling of "word" specified by an `eshell-special-alist'.
-@c @item in `eval-using-options', have a :complete tag
-@c It would be used to provide completion rules for that command. Then
-@c the macro will automagically define the completion function
-@c @item for `eshell-command-on-region', redirections apply to the result
-@c So that "+ > 'blah" will cause the result of the `+' (using input from
-@c the current region) to be inserting in the symbol `blah'.
-@c
-@c If a disk command is being invoked, the input is sent as standard
-@c input, as if a "cat <region> |" were invoked.
-@c
-@c If a lisp command, or an alias, is invoked, then: if the line has no
-@c ^J characters, it is divided by whitespace and passed as arguments to
-@c the lisp function. Otherwise, it is divided at the ^J characters.
-@c Thus, invoking `+' on a series of numbers will add them; `min' would
-@c display the smallest figure.
-@c @item write `eshell-script-mode' as a minor mode
-@c It would provide syntax, abbrev, highlighting and indenting support
-@c like emacs-lisp-mode + shell-mode.
-@c @item in the history mechanism, finish bash-style support
-@c For !n, !#, !:%, and !:1- as separate from !:1*
-@c @item support the -n command line option for "history"
-@c @item implement `fc'
-@c @item specifying a frame as a redirection target implies point's buffer
-@c @item implement ">FUNC-OR-FUNC-LIST"
-@c This would allow for an "output translator", that takes a function to
-@c modify output with, and the target. Devise a syntax that words well
-@c with pipes, and can accomodate multiple functions (i.e.,">'(upcase
-@c regexp-quote)" or ">'upcase").
-@c @item allow Eshell to read/write to/from standard input and output
-@c This would be optional, rather than always using the Eshell buffer.
-@c This would allow it to be run from the command line.
-@c @item write a "help" command
-@c It could even call subcommands with "--help" (or "-h" or "/?").
-@c @item implement stty
-@c @item support rc's matching operator, "~ (list) regexp"
-@c @item implement "bg" and "fg" to edit `eshell-process-list'
-@c Using "bg" on a process that is already in the background does
-@c nothing. Specifying redirection targets replaces (or adds) to the
-@c list current being used.
-@c @item have "jobs" print only the processes for the current eshell
-@c @item how do I discover that a background process has requested input?
-@c @item support 2>&1 and >& and 2> and |&
-@c The syntax table for parsing these should be customizable, such that
-@c the user could change it to use rc syntax: >[2=1].
-@c @item allow $_[-1], which reads the last element of the array, etc.
-@c @item make $x[*] equal to listing out the full contents of x
-@c Return them as a list, so that $_[*] is all the arguments of the last
-@c command.
-@c @item move ANSI code handling from `term' into `eshell-term'
-@c And make it possible for the user to send char-by-char to the
-@c underlying process. Ultimately, I should be able to move away from
-@c using term.el altogether, since everything but the ANSI code handling
-@c is already part of Eshell. Then, things would work correctly on Win32
-@c as well (which doesn't have "/bin/sh", though term tries to use it)
-@c @item have other shell spawning commands be visual
-@c Make (su, bash, telnet, rlogin, rsh, etc.) be part of
-@c `eshell-visual-commands'. The only exception is if rsh/su/bash are
-@c simply being used to invoke a single command. Then, it should be
-@c based on what that command is.
-@c @item create an alias "open"
-@c This will search for some way to open its argument (similar to opening
-@c a file in the Windows Explorer). Perhaps using ffap...
-@c @item alias "read" to be the same as "open", except read-only
-@c @item write a "tail -f" alias which does a view-file
-@c I.e., it moves point to the end of the buffer, and then turns on
-@c auto-revert mode in that buffer at frequent intervals -- and a head
-@c alias which assums an upper limit of `eshell-maximum-line-length'
-@c characters per line.
-@c @item make dgrep load dired, mark everything, then execute the A binding
-@c @item write emsh.c
-@c It just runs Emacs with the appropriate arguments to invoke eshell.
-@c That way, it could be listed as a login shell.
-@c @item use an intangible PS2 string for multi-line input prompts
-@c @item auto-detect when a command is visual, by checking TERMCAP usage
-@c @item First keypress after M-x watson triggers `eshell-send-input'
-@c @item Emacs 20.3: Figure out why pcomplete won't make
-@c @item Make / electric
-@c So that it automatically expands and corrects pathnames. Or make
-@c pathname completion for pcomplete auto-expand "/u/i/std<TAB>" to
-@c "/usr/include/std<TAB>".
-@c @item Write pushd/popd out to disk along with last-dir-ring
-@c @item add options to eshell/cat which would cause it to sort and uniq
-@c @item implement in Lisp: wc. Also count sentences, paragraphs, pages.
-@c @item once piping is added, implement sort and uniq
-@c @item implement touch
-@c @item implement epatch
-@c Calls ediff-patch-file, or ediff-patch-buffer, depending on its
-@c argument.
-@c @item have an option for bringing up ls -l result in a dired buffer
-@c @item write a version of xargs that's based on command rewriting
-@c find X | xargs Y == Y ${find X}. Maybe I could change
-@c eshell-do-pipelines to perform this on-thy-fly rewriting.
-@c @item implement head and tail in Lisp
-@c @item write an alias for less and more that brings up a view buffer
-@c Such that they can press SPC and DEL, and then q to return to eshell.
-@c The more command would be equivalent to: X > #<buffer Y>; view-buffer
-@c #<buffer Y>
-@c @item differentiate between aliases and functions
-@c Allow for a bash-compatible syntax, such as:
-@c
-@c alias arg=blah
-@c function arg () { blah $* }
-@c @item find the various references to shell-mode within Emacs
-@c And add support for Eshell there, since now Eshell is going to be part
-@c of Emacs.
-@c @item permit umask to be set on a cp target during the cp command
-@c @item if the first thing that I do after I enter Emacs
-@c is to run eshell-command and invoke ls, and then I use M-x eshell, it
-@c doesn't show me anything.
-@c @item M-RET during a long command doesn't quite work
-@c Since it keeps the cursor up where the command was invoked.

+@item Problem running @command{less} without argument on Windows
+
+The result in the Eshell buffer is:
+
+@example
+Spawning child process: invalid argument
+@end example
+
+Also a new @command{less} buffer was created with nothing in it@dots{}
+(presumably this holds the output of @command{less}).
+
+If @command{less.exe} is invoked from the Eshell command line, the
+expected output is written to the buffer.
+
+Note that this happens on NT-Emacs 20.6.1 on Win2000. The term.el

+
+@item Implement @samp{-r}, @samp{-n} and @samp{-s} switches for @command{cp}
+
+@item Make @kbd{M-5 M-x eshell} switch to ``*eshell<5>*'', creating if need be

+@item @samp{mv DIR FILE.tar} does not remove directories
+
+This is because the tar option --remove-files doesn't do so. Should it
+be Eshell's job?
+
+@item Bind @code{standard-output} and @code{standard-error}
+
+This would be so that if a Lisp function calls @code{print}, everything

+With @command{zsh}, the glob above expands to all files named
+@file{Root} in directories named @file{CVS}.
+
+@item Typing @samp{echo ${locate locate}/bin<TAB>} results in a Lisp error
+
+Perhaps it should interpolate all permutations, and make that the
+globbing result, since otherwise hitting return here will result in
+``(list of filenames)/bin'', which is never valuable. Thus, one could
+@command{cat} only C backup files by using @samp{ls ${identity *.c}~}.
+In that case, having an alias command name @command{glob} for
+@command{identity} would be useful.
+
+@item Fix `file-name-all-completions' for XEmacs on Win32
+
+Make sure it returns directory names terminated by

+than backslash.
+
+@item Once symbolic mode is supported for @command{umask}, implement @command{chmod} in Lisp
+
+@item Create @code{eshell-expand-file-name}

+@item Abstract @file{em-smart.el} into @file{smart-scroll.el}
+
+It only really needs: to be hooked onto the output filter and the

+And to know whether the last output group was ``successful''.
+
+@item Allow for fully persisting the state of Eshell
+
+This would include: variables, history, buffer, input, dir stack, etc.
+
+@item Implement D as an argument predicate
+
+It means that files beginning with a dot should be included in the

+$@{find X@}}. Maybe @code{eshell-do-pipelines} could be changed to
+perform this on-thy-fly rewriting.
+
+@item Write an alias for @command{less} that brings up a @code{view-mode} buffer
+
+Such that the user can press @kbd{SPC} and @kbd{DEL}, and then @kbd{q}
+to return to Eshell. It would be equivalent to:
+@samp{X > #<buffer Y>; view-buffer #<buffer Y>}.
+
+@item Make @code{eshell-mode} as much a full citizen as @code{shell-mode}
+
+Everywhere in Emacs where @code{shell-mode} is specially noticed, add
+@code{eshell-mode} there.
+
+@item Permit the umask to be selectively set on a @command{cp} target
+
+@item Problem using @kbd{M-x eshell} after using @code{eshell-command}
+
+If the first thing that I do after entering Emacs is to run
+@code{eshell-command} and invoke @command{ls}, and then use @kbd{M-x
+eshell}, it doesn't display anything.
+
+@item @kbd{M-RET} during a long command (using smart display) doesn't work
+
+Since it keeps the cursor up where the command was invoked.
