rfc patch, abort rm instead of only removing the * from the cmdline

It surprised me that this isn't already what happens, what do others think?
Imagine for example the typo
% rm -rf * /tmp
Before, even if you said no to the prompt, it will remove all your
files in /tmp.

A generic function/framework/mechanism for regular polling of data?

Hi all,

I was wondering if a function existed that will use a pattern, target
variables, interval & a data source for polling & parsing information
regularly.

For example, this function could be told to poll ACPI power status
every X seconds and put the result into $foo. The same function
could also keep track of unread mail, the temperature of CPU, HDD,
etc and pretty much antything else you can get from a file or
program and put all of those values into variables.

Does any function like this exist?

Multi-Minute Startup?

It takes zsh multiple minutes (around 3) to start up on a new server I
just got access to. I have no custom .z* files at this point, so all
that's running should be the /etc files, of which only /etc/zshenv and
/etc/zshrc are actually present. Any ideas what's likely to be slowing
me down so much?

Yodl has been discontinued for 13 years... zsh still uses it for texi docs?

ZSH 4.3.6 fails to compile (module.c: 1453) on AIX 5300-08-01 (AIX 5.3 TL 8), ZSH 4.2.7 compiles

Hi. I'm trying to build zsh 4.3.6 on AIX 5300-08-01 using gcc 4.2.4
and Autoconf 2.61. Configure works fine, but the build fails after
some time with:

        gcc -c -I.  -DHAVE_CONFIG_H -Wall -Wmissing-prototypes -O2  -o
linklist.o linklist.c
        gcc -c -I.  -DHAVE_CONFIG_H -Wall -Wmissing-prototypes -O2  -o
loop.o loop.c
        gcc -c -I.  -DHAVE_CONFIG_H -Wall -Wmissing-prototypes -O2  -o
math.o math.c
        gcc -c -I.  -DHAVE_CONFIG_H -Wall -Wmissing-prototypes -O2  -o
mem.o mem.c
        gcc -c -I.  -DHAVE_CONFIG_H -Wall -Wmissing-prototypes -O2  -o
module.o module.c
module.c: In function 'load_and_bind':
module.c:1453: warning: assignment from incompatible pointer type
module.c:1454: error: 'struct module' has no member named 'flags'
module.c:1455: error: 'struct module' has no member named 'flags'
make: 1254-004 The error code from the last command is 1.

Stop.
make: 1254-004 The error code from the last command is 2.

Stop.
make: 1254-004 The error code from the last command is 2.

Stop.

That line in module.c looks like:

 if (!(m->flags & MOD_ALIAS) && m->u.handle && !(m->flags &
         MOD_LINKED)) err |= loadbind(0, m->u.handle, ret);

Like I've said, I'm happily running ZSH 4.2.7 so this is probably some
newly introduced issue.

zle widgets coolness: pipe command template

Wrote my first zle widget, thought I'll share:

# define-pipe-widget <widget-name> "template1" "template2" ....
#
# Defines "pipe widget" templates. Its hard to describe the best way
# is through an example:
#
# define-pipe-widget insert_grep  "grep \"@@@\"" "grep -i \"@@@\"" "grep @@@" 
# define-pipe-widget insert_head "head" "head\n"
#
# bindkey "\M-g" insert_grep
# bindkey "\M-h" insert_head
#
# Now pressing Alt-G will insert (| represents cursor position)
#
# On empty command line: grep "|"
#
# On non-empty command line: <old cmdline> | grep "|"
#
# Pressing Alt-G one more time cycles through choices
# ie:
#  ... |  grep "|"
#  ... | grep -i "|"
#  ... | grep
#  
# If template has \n in the end, then it will be auto-accepted:
# 
#      Alt-H does: ... | head <cursor here>
#  2nd Alt-H does  ... | head<Enter>
#

completion: highlight matching part

Hi,

is it possible for zsh to highlight (bold, change color etc.) of
matching part of available completions? E.g.

$ ls abcd[tab]
abcd123		abcd456		abcd789
abcdefg		abcdhij		abcdklm

and I'd like the 'abcd' to be lightgreen.

Now it's sometimes hard to find out what character to type next, this
solution would make it easier.

Setting the cursor position upon completion

recurse up

One can find files that live below the current directory via

	ls **/README

but how can one look for files in the parent, grand-parent, ...
directories?

For example, suppose that the file /a/README exists and the current
directory is /a/b/c/d/e. Then, I'd like

	ls .../README

to glob expand to ../../../README.

Any suggestions?

			Anthony.

approximate filename globbing

I have trouble understanding the "Approximate Matching" section
in the zsh manual.

Assume I have in my directory files cn1.pl, cn2.pl, cn3.pl, and
I use the following glob pattern:

  ls (#a2)cnx.pl

I had expected to see all my cn?.pl displayed, but instead I 
get a "zsh: no match" error.

How do I correctly use (#a...) for globbing?

PATCH: option for completion file-sort to follow symlinks

I have all my dotfiles under version control in a separate directory,
and ~/.zshrc ~/.zalias etc are symlinks to the version controlled
directory.

So even when I have: "zstyle ':completion:*:*:*:*' file-sort date"
doing vi ~/.z<Tab> sorts the files based on symlink modtime and not
the file that its pointing to.

The one line patch included into the end of this email adds one
additional option `follow' to the file-sort, which makes it follow
symlinks.

# follow symlinks when sorting
zstyle ':completion:*:*:*:*' file-sort date follow

Regards,
  Max
