PATCH: prompt theme system improvements

PATCH: prompt theme system improvements

[Adam Spiers]

OK, finally here's a patch to the prompt system which vastly improves
it.  After applying the patch, you should remove the following from
Functions/Prompts:

  prompt_{white,red,green,yellow,blue,cyan,magenta,combo}_setup

if the patch didn't succeed in getting rid of them.  (The patch was
made for copies of Tanaka's CVS archive, by the way.)

To get a very quick feeling of the changes, fire up a black background
terminal, preferably with the `nexus' or `vga' font or similar, type
`prompt -p' and gasp in horror at the tasteless colour combinations.


Changes in full gory detail:
----------------------------

  - Colours are now all in assoc arrays.

  - `prompt -c' shows current theme (with parameters if any).

  - All the {red,green,blue,...} themes merged into one fully
    colour-scheme-able `fade' theme.

  - `combo' theme converted to colour-scheme-able `bigfade' theme.

  - `adam1', `fire', `elite' and `elite2' made colour-scheme-able.

  - Added some more help texts for individual themes.

  - Mentioned that dark backgrounds work best in help texts.
  
  - If a theme defines a prompt_$themename_preview function, when that
    theme is being previewed, that function gets invoked rather than
    the normal previewing, which allows a colour-scheme-able theme to
    show more than one colour scheme for its preview.

  - Previewing semantics changed:
      + If no words specified after `-p', preview all themes.
      + If words specified after `-p', treat each word as a theme plus
        its arguments, and preview it accordingly.

  - Use of $'' instead of $(echo -n "") hack wherever possible.

  - Needless use of $(echo "") elsewhere removed.

  - Added zefram's prompt.

  - Fixed bug in Oliver's prompt; it doesn't work if you don't set up
    anything relating to it.  The guilty line is:

      local pcol="$'\e['${1:-${pcolour[${HOST:=`hostname`}]:-33}}m"

    If pcolour is non-existent or not declared as associative, the
    ${pcolour}[${HOST:=`hostname`}] bit barfs if ${HOST:=`hostname`}
    contains a `.' in it, which is quite likely.  So you need check
    the value of ${(t)pcolour} before doing this assignment.  This
    applies to tcolour too, of course.

  - There is now a pseudo-theme called `random'.  It defaults to
    picking randomly from all available themes (but without any
    supplied parameters to any), but if you give it arguments, each
    argument word will be treated as a theme with arguments.  For
    example:

      % prompt random "elite2 green" "elite2 blue" fire

    The `random' theme does not work in preview mode.

  - Other improvements I can't remember.


Known bugs:
-----------

  - I notice that the _prompt completion function no longer works,
    presumably through one of the many changes to arguments.  I'll try
    to fix this unless someone gets there first.

  - Some of the colours are tasteless.  Beauty is in the eye of the
    beholder ...  Contributions from graphic designers/artists welcome :-)

  - It would be nice to be able control the `bold-ness' of the colours
    provided as theme provided.

  - precmd and preexec still get stomped on.  I think the solution to
    this is to use Bart's addprecmd to add a hook to them both which
    calls prompt_pre{cmd,exec} respectively the first time promptinit
    is run, and then subsequent theme changes can alter these hook
    functions without messing up the original pre{cmd,exec}.  Does
    that sound reasonable?


Unknown bugs: 
-------------

  - There are many changes here, so there may be a few problems
    created.  Please test!

I was just fooling with this, and after running

and I'm left with the "adam1 theme" prompt, which happens to be the last

Doh.  The

    p) if (( ! $+prompt_theme )); then
         print "Cannot preview; current prompt is non-themeable and would"
         print "be destroyed."
         return
       fi

bit should have caught this, but I'd already declared prompt_theme so
the test went wrong.

However, it's pretty bad that you can't preview any themes until
you're using one, so this patch changes that, and restores PS[1-4],
RPS1 and pre{cmd,exec} to their original values after the preview if
$prompt_theme wasn't set.

It also fixes some other bugs I found.

N.B. I forgot to mention that that last patch added the following files:

Usually, my script adds new files automatically.  So I don't need such
notices.  However, file removing/moving/reverting requires some manual
work and sometimes I forget them...

In reality, I have a directory which contains latest zsh and is *not*
maintained by cvs.  The directory is updated by patches from
zsh-workers and zsh-users and the repository is updated by `cvs
import' for each patch.  So, new files are automatically appeared on
main trunc when a patch create these files.  When some files are
removed, `cvs rm' is needed.  When some files are moved, these files
must be moved manually and `cvs import' is needed.  Sometimes I omit
the `cvs import' because it'll be executed with next patch, though.
When some files are reverted, `cvs add' and `cvs admin -b1.1.1' is
needed.

This is much better. We should maybe add the 'gray' spelling aswell as 'grey' to the associative arrays so people have the choice. I'd also put the other attributes in an associative array so instead of $boldcolor, we have $color_attr[reset, bold, underline, standout] etc.

I've patched the 'oliver' prompt to use the colour names aswell patch follows.

I suppose that we should allow the different prompts to specify completion for their parameters. Only trouble is that we can't get at any functions in the prompt until they have been setup.

I'd also say that it isn't exactly wise that the majority of the example prompts require a strange font.

I've done this with the 'oliver' prompt in the patch below - precede the colours with the word 'bold'.

That sounds like the best solution.

I also think it would be sensible for promptinit to save the original PS2 and PS3 and set them back to the originals before changing prompt. This means that any prompts which don't set them will use the original settings instead of those set by the last theme. 

The patch below makes a few of your prompts use prompt_opts insead of precmd. I've added 'true' to the end of the prompt function because it was returning an exit code of one half the time. It should probably return set_prompt's return code and set_prompt should return sensible exit codes and send its error messages to stderr but I haven't done this.
The typeset -g prompt_theme line echos the value of prompt_theme if it is set so I redirected it to /dev/null. I also updated my prompt with some other changes.

With respect to colour themes. It would be good to have a single way for defining colours across zsh. ZLS_COLOURS may be compatible with GNU ls but it isn't exactly the most readable way. One possible way would be to use an associative array for colours where the keys specify the context and the values specify the attributes. So for example, you might define:
zsh_colours[ls_directories]="bold blue on white"
zsh_colours[prompt_currentdir]="underlined green"
If different prompt themes use the same context words, you could share colour selections across prompts. It might also lead to a mechanism for defining the colours for different types of completion matches in the lists - not just for files.

Ah. See? I suggested then when I first started participating in the
coloured-completion-lists discussion.

> One possible way would be to use an associative array for colours where the keys specify the context and the values specify the attributes. So for example, you might define:

Ick. Maybe we should keep the parameter side more standard and just
use `bold:blue:white' or `bold:fg=blue:bg=white' or something. And
then add a function that uses a mini-language... err, wait, where have 
I heard that before.

I have almost given up dreaming about it, but: stuff like this always
reminds how nice it would be to generalise some of the completion-setup 
stuff to a more general package system. And then allow something like: 
`zstyle 'prompt:...:foreground' bold blue'.

> If different prompt themes use the same context words, you could share colour selections across prompts. It might also lead to a mechanism for defining the colours for different types of completion matches in the lists - not just for files.

...which complist currently can't do because it uses ZLS_* only for
files. But I have already asked: should we change it to allow using
pattern-capabilities for normal matches, too? The only problem I have
with that is that I would like to be able to give such specs per group 
of matches added. And that would require changes to compadd which
doesn't (and, in my opinion, shouldn't) know about complist. Hrm.

I see... I hope I remember that in the future.

.distfiles are handled as usual files.  So it is not updated
automatically.  I don't plan automatic update for .distfiles.  But if
patches for .distfiles are posted as well as for other files, it is
useful to check consistency of the repository.  Also, package makers
need up-to-date .distfiles, I think.

And this is my consistency checker between .distfiles and CVS/Entries.
Currently, this reports only one problem: _funcall is forgotten.

while we're at it... does the automatic updating of .distfiles work?
Or do you need patches like the one below which Sven constantly keeps
forgetting to build?
