Subject: Escape characters in $psvar[]
Date: Fri, 19 Nov 2010 14:04:35 +0100 [thread overview]
Message-ID: <871v6h79cs.fsf@ft.bewatermyfriend.org> (raw)
Hey list,
The following came up on IRC.
A user uses the `clint' prompt, which uses `psvar' to include results
from `vcs_info'. He wanted to include colour codes in the vcs_info
formats for proper eye candy. Which resulted in literal "^[[35m" strings
in the actual prompt instead of colours.
It seems using $psvar[] replaces escape characters (ascii 0x1b) with two
characters: `^' and `[':
[snip]
% autoload -Uz colors
% colors
% psvar[9]=$fg[red]foo
% print ${psvar[9]} | hd -c
00000000 1b 5b 33 31 6d 66 6f 6f 0a |.[31mfoo.|
0000000 033 [ 3 1 m f o o \n
0000009
% print -P '%9v' | hd -c
00000000 5e 5b 5b 33 31 6d 66 6f 6f 0a |^[[31mfoo.|
0000000 ^ [ [ 3 1 m f o o \n
000000a
[snap]
Is that indented behaviour or a bug? A quick skim through the docs
didn't turn up an answer.
Regards, Frank
