   Surprised by this behavior...is this a bug?

   (Goal:  e.g.  distinguish  between  completely  numeric args/names and
   those containing non-numerics)

 % touch 1023 pex103 pex103a 104a z101 16a02 1999 2001 2001_A_Space_Odyssey
 % ls -1 *[^0-9]*
 104a
 16a02
 2001_A_Space_Odyssey
 pex103
 pex103a
 z101
 # (great, looks good to me. Got everything containing a nonnumeric, no more, n
o less.)

 % foreach p ( 1023 pex103 pex103a 104a z101 16a02 1999 2001 2001_A_Space_Odyss
ey )
 foreach? if ( $p !~ *[^0-9]* ) echo $p
 foreach? end
 # (no output. Huh?)

 % foreach p ( 1023 pex103 pex103a 104a z101 16a02 1999 2001 2001_A_Space_Odyss

 # (Huh?)

   The [MAN page description] for =~ and !~ just refer to "(see [Filename
   substitution])',  but  evidently  there is a (unexplained) difference.
   The  actual  filename  globbing  looks  correct to me, but the pattern
   matching   operator   behavior  is  unexpected,  if  I'm  not  missing
   something.

   tcsh 6.09.00

   Wish "tcsh -l" would accept other flags. At least "-c".

   Currently I can't get ssh to have the right environment unless it is a
   login  shell. The .ssh/environment doesn't work for me because I login
   to  different  machines  with  different environments. One thing to do
   would  be  to not have the different environment for login compared to
   other shells, but what I would really like is something like...

   ssh remote_application_server "tcsh -l -c application"

   The "ssh -t" doesn't work for me and I don't know why.

   Thanks Tim

   Fix limit vmemoryuse in Linux

   In  Linux  tcsh  is  unable  to  limit  vmemoryuse.  This  is  because
   RLIMIT_VMEM isn't defined, instead Linux has RLIMIT_AS which means the
   same.  On  Google  groups  I  found  patches  suggested by Komazaki at
   http://groups.google.com/groups?hl=sv&lr=&ie=UTF-8&oe=ISO-2022-JP&selm
   =m3snmczvfc.wl%40thinkpad.osk.3web.ne.jp.osk.3web.ne.jp    and   Ogawa
   Hirofumi suggests a patch at
   http://groups.google.com/groups?hl=sv&lr=&ie=UTF-8&selm=87snmba4id.fsf
   %40devron.myhome.or.jp  None  of  these  patches  seems  to  have been
   included in version 6.12 as 6.12 still has this problem.

   New  idea:  use  last  line  (or  n'th line) of output as input to new
   command.

   I often find myself typing something like:

   >locate lshort
   /usr/local/stow/share/texmf/doc/latex/general/lshort.dvi    .    .   .
   /usr/local/store/share/texmf/doc/latex/general/lshort.dvi

   >xdvi /usr/local/store/share/texmf/doc/latex/general/lshort.dvi

   Now the way I accomplish writing the last line, is by moving the mouse
   over  the  last line, and the copy paste it. It would be very nice, if
   the  shell could keep the last n lines of output in a buffer. This way
   one could avoid using the mouse by typing something like:

   >xdvi <M-1>

   which  would  insert  the  last  line of output, similarly <M-2> could
   insert  the second last line of output. (the exact commands used is of
   course configured via bindkey).

   This  could  save  me  a  couple  of  times  to  the  mouse everyday -
   di010070@diku.dk

          The shell does not capture any output from commands it runs, so
          this  is really more a feature for the terminal (be it hardware
          or software). --Kim

   Fix  memory  leak  related  to  aliasrun().  Precmd,  Cwdcmd etc. leak
   memory.

   Fix migrate -site $$... Seems to hang... (aix370)

   Fix history in loops.

   New idea: sed operations on variables.

   Lots  of  people  seem  to  like  the  idea  to be able to do sed type
   operations  on  shell variables. Maybe we can extend the syntax of the
   variable  editing  to understand string operations. So I would like to
   be able to use:

> set a="this is a STRING"
> echo $a:[3-]
is is a STRING
> echo $a:[#]
16
> echo $a:[6-7]
is
> echo $a:[-2]
ng
> echo $a:[-20]
Subscript out of bounds.
> echo $a:[2-20]
Subscript out of bounds.
> echo $a:[1-1]:u$a:[2-].
This is a string.

   Fix pipelines that contain builtins so that they behave correctly.

   I  tried  to  fix  that (most of the code is in sh.sem.c, but it works
   only  for  non  POSIX  machines  cause otherwise the setpgid() I added
   fails).

   Fix the correct code... How to do that involves A.I....

   Rewrite  the  whole  thing.  It  has  taken  to  much beating over the
   years...

   Add  another  hook  like  precmd  to  be executed after the prompt but
   before the command.

   Add instructions for using configure in the README file.

   Make manual page references links in the HTML version of the manual.

   It is possible to match the words with ([0-9]) after them. Links could
   be  using the manual page CGI at http://www.tac.eu.org/cgi-bin/man-cgi
   for content.

   Add OpenBSD?? to the Makefile, etc.

   A  Csh compatability mode would be nice: I know tcsh is supposed to be
   fully  csh  compatible,  but csh scripts containing such constructs as
   '$<'  ,  'if  ( -d $file ) cd $file' or any of a great number of other
   valid  csh commands, will produce syntax errors or the like with tcsh,
   which  is  frustrating when writing/maintaining csh scripts which have
   to  run on systems with only tcsh and systems with only csh. If such a
   thing  exists, I couldn't find it after searching the man page for two
   hours, and it should be better documented

   Add  hooks  for  command  completion  Either  for a dynamically loaded
   library,  or a callback to another program that allows another pass to
   complete the command. As a trivial example, the module could duplicate
   the  functionality of aliases. A tcsh_mud.so could define sigh, groan,
   cheer,  lol,  etc  to  produce  output  if they weren't actually valid
   commands.

   Properly deal with : in filename substitution

   Given something like

   blah.foo:*.foo

   expand it properly to something like

   blah.foo:baz.foo:bob.foo:bar.foo

   It already does this, if you have a file named like that... --Kim

   Directory  commands  don't  handle  blanks  in filenames. If I have an
   environment variable such as:

% setenv TOMCAT '/c/Program? Files/Apache? Software Foundation/Tomcat? 5.0'
and then do the following, setenv complains that it has too many arguments.
% cd /tmp
% cd "$TOMCAT"
setenv: Too many arguments
% dirs
/c/Program? Files/Apache? Software Foundation/Tomcat? 5.0 /tmp
% pushd "$TOMCAT"
/c/Program? Files/Apache? Software Foundation/Tomcat? 5.0
setenv: Too many arguments.
% pushd /tmp
/tmp /c/Program? Files/Apache? Software Foundation/Tomcat? 5.0
% pushd
/c/Program? Files/Apache? Software Foundation/Tomcat? 5.0 /tmp
setenv: Too many arguments.

   Wish  tcsh  would feature fc (fix command) as in bash !Wish tcsh would
   featuer fc (fix command) as in bash !

   i  wish  for  read-only  CVS  access  to  the  sources (as i am on the
   bleeding egde)

   Functions  would be useful! As would being able to redirect stderr (or
   other file descriptors) independently of stdout! -- Rohan Talip

   Don't  complete  commands  with non-executable files. For example if I
   have a file called README in a directory in the PATH, and I type R TAB
   tcsh will complete README as a command. But README does not have the x
   bit set, so it's kind of pointless to have that completion.

   -->  Setting the shell variable "recognize_only_executables" will give
   you this behavior. --Waz

   If  I  have  in  my  .tcshrc:  complete  {cd,pushd}  p/1/d/ and I type
   "complete cd" at the shell prompt nothing is printed. It would be nice
   if {cd,pushd} p/1/d/ was printed.

   -->  I  had programmed this feature a while ago but have not submitted
   it  because  the implementation is not robust enough to keep TCSH from
   crashing  when  special  characters  are part of the pattern. I'll get
   back to it at some point! --Waz

   It would be nice if "set autolist" would be on by default.

   Unicode  (UTF-8) doesn't seem to work. It's not even possible to "make
   catalogs"  in  unicode  environment.  Also  unicode support (and other
   multibyte   encodings)   should   depend   on   environment  variables
   (LC_CTYPE),  not  on  "set dspmbyte". On unicode terminal translations
   show empty characters instead of messages.

   In addition to message catalogs, there are more problems:
ipi:~/test/tcsh/bin> ls
tcsh  <20><><EFBFBD>
ipi:~/test/tcsh/bin> set dspmbyte utf8
ipi:~/test/tcsh/bin> ls ???
ls: No match.

   Unicode is used more and more, and is default on many environments, so
   this really should be fixed. --mpaananen
     _________________________________________________________________

   When I have a script called from complete I would like to have the the
   existing  text  from the command line passed to that script so that it
   can  look  at  all existing words to detemine what it should output as
   the completion list.

   For example:

   complete prog 'n/-x/`myscript`'

   Then when I do this:

   > prog -a A -b B -x <TAB>

   The script would get 'prog -a A -b B -x ' which would allow the script
   to  base  its -x completions on the options given for -a and -b (or if
   they  aren't  present give nothing - or a message saying that they are
   required).  Setting  a temporary environment variable before executing
   the command would also work and would probably be safer.

   Perhaps  this info is already available as a special variable that can
   be  manually  passed  to  the  script:  complete  prog 'n/-x/`myscript
   $cmd_line`'?

   Update:  I  looked  into this further by actually downloading the code
   and  looking  through  it.  It  doesn't  seem that this information is
   available  anywhere,  but  I  did  manage  to achieve what I wanted by
   adding  the  following  two lines around the call to tw_complete (line
   278, tw.parse.c 6.12.00):

   added> tsetenv(STRCURRCMDLINE, (Char *)&qline);
        looking = tw_complete(cmd_start, &wordp, &pat, looking, &suf);

   added> Unsetenv(STRCURRCMDLINE);

   And I added a definition for STRCURRCMDLINE to be "CURRCMDLINE".

   This   provides   the   environment   variable   CURRCMDLINE   to  any
   script/program running under complete. The only issue I see is picking
   a  sufficiently obscure environment variable that noone else is likely
   to  use,  but have it readable enough to understand what it is for. It
   also  shouldn't overwrite an existing ENV variable if it is already in
   use.
