For starters, you can just try an empty string (I've added default
values -- those that are mentioned in my GNU-ls manual).

Otherwise it looks termacapish: a colon-separated list of `<cap>=<val>'.
Where <val> is a number (on a vt* terminal or xterm):

  1 for bold
  4 for underlined
  7 for standout
  3[0-7] for foreground colours
  4[0-7] for background colours

...for the colours you need an xterm that can display them, of course.

The rest form the ls-manual I have:

       You can override the default colors by defining the  envi-
       ronment variable LS_COLORS (or LS_COLOURS).  The format of
       this variable is reminicent of the termcap(5) file format;
       a   colon-separated   list  of  expressions  of  the  form
       "xx=string", where "xx" is a two-character variable  name.
       The variables with their associated defaults are:

         no       0       Normal (non-filename) text
         fi       0       Regular file
         di       32      Directory
         ln       36      Symbolic link
         pi       31      Named pipe (FIFO)
         so       33      Socket
         bd       44;37   Block device
         cd       44;37   Character device
         ex       35      Executable file
         mi       (none)  Missing file (defaults to fi)
         or       (none)  Orphanned symbolic link (defaults to ln)
         lc       \e[    Left code
         rc       m       Right code
         ec       (none)  End code (replaces lc+no+rc)

       You  only need to include the variables you want to change
       from the default.

       File names can also be colorized based on filename  exten-
       sion.   This  is specified in the LS_COLORS variable using
       the syntax "*ext=string".  For  example,  using  ISO  6429
       codes, to color all C-language source files blue you would
       specify "*.c=34".  This would color all files ending in .c
       in blue (34) color.

       Control  characters  can  be  written  either  in  C-style
       \-escaped notation, or in stty-like  ^-notation.   The  C-
       style  notation  adds \e for Escape, \_ for a normal space
       characer, and \? for Delete.  In addition,  the  \  escape
       character  can be used to override the default interpreta-
       tion of \, ^, : and =.

       Each file will be written as <lc> <color code> <rc> <file-
       name>  <ec>.   If the <ec> code is undefined, the sequence
       <lc> <no> <rc> will be used instead.   This  is  generally
       more convenient to use, but less general.  The left, right
       and end codes are provided so you don't have to type  com-
       mon  parts over and over again and to support weird termi-
       nals; you will generally not need to change  them  at  all
       unless your terminal does not use ISO 6429 color sequences
       but a different system.

       If your terminal does use ISO 6429 color  codes,  you  can
       compose the type codes (i.e. all except the lc, rc, and ec

       codes) from numerical commands  separated  by  semicolons.
       The most common commands are:

          0     to restore default color
          1     for brighter colors
          4     for underlined text
          5     for flashing text
         30     for black foreground
         31     for red foreground
         32     for green foreground
         33     for yellow (or brown) foreground
         34     for blue foreground
         35     for purple foreground
         36     for cyan foreground
         37     for white (or gray) foreground
         40     for black background
         41     for red background
         42     for green background
         43     for yellow (or brown) background
         44     for blue background
         45     for purple background
         46     for cyan background
         47     for white (or gray) background

       Not  all  commands  will  work  on  all systems or display
       devices.

       A few terminal programs do not recognize the  default  end
       code  properly.  If all text gets colorized after you do a
       directory listing, try changing the no and fi codes from 0
       to  the  numerical codes for your standard fore- and back-
       ground colors.

I, at least, am. That's why I'm not planning to give this real support.

Switching on menu-select instead of menu-complete: no. This was at
least half-intentional because menu-select takes over control
completely. You can, however, go from normal menu completion to
menu-select and back again (if you have it bound to a key).
And of course you can use menu-select as one of the styles to use for
the new completion system (after loading collist).

Doing this with an option or configuration key is currently not
possible because zle/comp1/compctl don't know about collist. And I
would like to have some more feedback before I start thinking about
ways to support this. Ok?

Wow! I was tempted to ask for it long long time ... but I always had a feeling,
that zsh-workers are more of the old Unix teletype guys :-)

Is it possible to transparently use menu-select instead of menu-complete? I
mean, I currently have TAB bound to complete-word with additional stuff like
menu et al governed by configuration keys. Can I still use menu-select in this
case? Some configuration key to use menu-select instead of menu-complete
transparently ...

> [ ... collist ... ]

This one is even weirder... (if memory serves, Peter once talked about 
this).

It adds:
- the `ma' capability to collist; it is used during menucompletion to
  highlight the match inserted (note that you still have to set
  `ZLS_COLO(|U)RS' to see this -- an empty string will suffice)
- the `menu-select' widget which is a bit like `menu-complete' but
  displays the list and then lets you use cursor-movement keys to
  navigate in the list; to return to line editing, you can use
  `accept-line' or `send-break'; `accept-and-hold' leaves the match
  inserted in place and continues selecting matches from the list
  (i.e. it's like `accept-and-menu-complete')

Dunno if this is interesting to anyone, so I haven't written a manual
for this. (sorry :-}

Ahem ... I've never used GNU ls, so, what should I put in there? I believe, it
is better be described in Zsh doc.

I just looked fileutils-4.0. Man page for ls says nothing; info has entry for
dircolors that just tells, that it's output should be assigned to LS_COLORS
variables and suggests running dircolors --print-database for more info :-) I
don't have fileutils (and won't have on this system)

So - what should I put in ZLS_COLORS to get colored listing?

Errr... since you had announced that you wanted to work on the widget
stuff I had to find something else to work on at the weekend whenever
I was fed up with real work, so:

This adds the `collist' module (there may be a better name). If you
load/link it and set `ZLS_COLORS' or `ZLS_COLOURS' to a string as the
one used by the colour ls, you get colourised completion lists.

Some comments:
- I haven't checked if this behaves exactly like the colour-ls
  thing. Greg, could you test/modify this? One thing I know is
  different is that I didn't use the `or' capability (orphaned
  links). Also, I made the colour-codes be used for the filling-
  spaces after the names, too (looks better with coloured backgrounds, 
  I think).
- I haven't bothered to explain the parameters in the docs. Anyone who 
  will use this (I won't) is invited to improve the manual (it's in
  mod_collist.yo).
- we could enhance in several ways, of course...
- oh, and there is no GNU code used here (that's part of the reason
  why I'm not sure if it behaves like GNU-ls)

That was the uninteresting part. Here's the interesting one:

For this I had to keep zle_tricky.c from calling listmatches()
directly. The simple solution would be to add a function pointer
variable which is used for that, obviously. But this is an invitation
to module programmers, so there might be multiple modules that
save/set/restore this pointer and combinations of loading/unloading
modules that leave the pointer in an invalid state.
So I added support for (C-)hooks in module.c. This is currently very
simple (i.e. not very powerful), but it's enough for this purpose. See 
the description in zsh-development-guide if you are interested.

Bye
 Sven

I will put this in if I can get it and the permission to do so.

Wayne points out that the diff is missing the patch for Src/version.h.
I've noted that problem in ftp://ftp.brasslantern.com/pub/zsh/README;
there's no point in sending a diff for a one-character change.

Sorry about that.

Patch available for 3.0.6-pre-5

[Bart Schaefer]

I've made up another pre-patch for 3.0.6, which carries the version number
3.0.6-pre-5.  The set is now:
        ftp://ftp.brasslantern.com/pub/zsh/zsh-3.0.5-3.0.6-pre-0.diff
        ftp://ftp.brasslantern.com/pub/zsh/zsh-3.0.6-pre-0-pre-1.diff
        ftp://ftp.brasslantern.com/pub/zsh/zsh-3.0.6-pre-1-pre-2.diff
        ftp://ftp.brasslantern.com/pub/zsh/zsh-3.0.6-pre-2-pre-3.diff
        ftp://ftp.brasslantern.com/pub/zsh/zsh-3.0.6-pre-3-pre-4.diff
        ftp://ftp.brasslantern.com/pub/zsh/zsh-3.0.6-pre-4-pre-5.diff

Remember that after applying patches to 3.0.5, you must "touch stamp-h.in"
before running configure to prevent make from attempting to rerun autoconf
and autoheader.

Checksums on the latest diff:

(BSD)  61167   137
(SYSV) 60127 273 zsh-3.0.6-pre-4-pre-5.diff

The big change here is the 64-bit and large file support (thanks, Peter).
If you have a system where this is useful, please check this if you can.

This is the last "pre" release.  I plan to make a test release through
the official FTP site before the end of the month; if all goes well with
that, the final release will be in mid-July.

Remarks about this patch:

* After much consideration, taking into account the commentary elicited on
  the zsh-users list, I have decided that Greg Badros's ZLS_COLORS patches
  will have to wait for Peter to include them in 3.1.x.  Sorry, Greg; it
  did seem that there's enough support for it to be worth getting a GPL
  exemption from the FSF, but I'm swayed by the argument that fewer new
  features is better in the case of 3.0, so I've tried to pick up only bug
  fixes (including compatibility ones) since -pre-4.

* For the same reasons, I did not adapt Sven's PS4-promptpercent patch,
  though I waffled a lot about it.

* This patch is a unified diff (previously I've been doing context diffs)
  because it's 40% smaller that way.  It's still the largest patch in the
  set so far ....

* There are two primary reasons the patch is so big:
  1. 64-bit support makes many small changes in lots of files.
  2. I upgraded to autoconf 2.13, which exaggerates the configure diff.

* I haven't updated the META-FAQ, but will before the final release.  I'm
  also expecting Sven to fix the bug I reported in 6722.  Otherwise I do
  not plan on making any more changes before the test release, and of
  course only bugfixes after.

* Have I forgotten anything?
