Subject: 8-bit parameter names?
Date: Mon, 09 May 2005 17:24:50 +0000 [thread overview]
Message-ID: <1050509172451.ZM11220@candle.brasslantern.com> (raw)
Is it intentional that 8-bit characters can be used in parameter name
identifiers, or is it a bug?
I was just looking at prompt_elite2_setup again, which has this comment:
Recommended fonts for this theme: nexus or vga or similar. If you
don't have any of these, the 8-bit characters will probably look stupid.
In fact, the 8-bit characters don't look like anything at all, because
they're never displayed. They're never displayed because the assingment
to PS1 is full of stuff like "$punctuation_colorU$textA..." where I've
replaced an 8-bit U-with-acute and A-with-umlaut with ascii U and A for
mailing list sanity.
The parameter code is treating e.g. U-with-acute as a valid part of the
identifier and finding no such parameter, so large parts of the elite2
prompt have simply been disappearing. (If set_prompt didn't execute
"emulate -L zsh" (which turns off the "nounset" option) this would have
been much easier to catch.)
The prompt_elite2_setup function, meanwhile, was apparently meant all
along to be as follows; not sent as a patch because again I'm avoiding
sending 8-bit characters to the mailing list.
prompt_elite2_setup () {
local text_col=${1:-'cyan'}
local parens_col=${2:-$text_col}
for code in 332 304 300; do
local varname=char_$code
: ${(P)varname=$(echo -n "\\0$code")}
done
local text="%{$fg_no_bold[$text_col]%}"
local parens="%{$fg_bold[$parens_col]%}"
local punct="%{$fg_bold[grey]%}"
local reset="%{$reset_color%}"
local lpar="$parens($text"
local rpar="$parens)$text"
PS1="$punct$char_332$text$char_304$lpar%n$punct@$text%m$rpar$char_304$lpar%!$punct/$text%y$rpar$char_304$lpar%D{%I:%M%P}$punct:$text%D{%m/%d/%y}$rpar$char_304$punct-$reset$prompt_newline$punct$char_300$text$char_304$lpar%#$punct:$text%~$rpar$char_304$punct-$reset "
PS2="$parens$char_304$text$char_304$punct-$reset "
precmd () { setopt promptsubst }
preexec () { }
}
