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

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

# (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.

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.
|
||
|
||

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.

/Henrik??
|
||
|
||
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 -

||

|
||
|
||
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.
