I'm running Vim 7.4.1152 in an xterm on a Red Hat Enterprise Linux
7.1 system and using Dr. Chip's AnsiEsc plugin (v13i) to make ANSI
color escape sequences in some files readable.
I noticed some odd behavior and simplified the conditions down to
this (one line).
$ vim -N -u NONE -o2 --cmd 'so plugin/cecutil.vim' --cmd 'so
plugin/AnsiEscPlugin.vim' --cmd 'au BufWinEnter * AnsiEsc' --cmd 'au
ColorScheme * AnsiEsc!'
I used "-o2" to make the current-window and not-current-window
status lines visible.
The initial appearance of the screen is as expected: the status
lines are in inverse video with "[No Name]" on the left and no other
characters in them, and the empty buffer lines are indicated by a
blue tilde in the first column. Now execute
:colorscheme default
(The name of the color scheme doesn't seem to matter.) All
highlighting disappears: the status lines and the tildes are white
on black. In addition, the "empty" space on the current-window
status line is filled with carats (^) and the space on the
not-current-window is filled with equal signs (=). The screen looks
like this (with redundant lines and columns removed for clarity):
~
~
~
~
[No Name]^^^^^^^^^^^^^^^^^^^^
~
~
~
~
[No Name]====================
Executing ":hi" shows almost all the highlights have been cleared,
e.g.,
SpecialKey xxx cleared
The corruption of the highlighting occurs when "AnsiEsc!" is
executed by the ColorScheme event. If I remove that autocommand and
execute ":AnsiEsc" from the command line, nothing odd happens.
I don't know whether this is a bug in the AnsiEsc plugin or in the
processing of the ColorScheme autocommand event, or perhaps in some
command the AnsiEsc plugin is executing, so I thought I'd post this
here rather than send it just to Dr. Chip.
Regards,
Gary
