* Marker does not point anywhere
Executing the following:
#+begin_src sh :session NoSuchSessionYet
cd ~
ls *.txt
#+end_src
outputs this in *Messages*:
: executing Sh code block...
: think it is Cygwin...
: ~
: ansi-color-process-output: Marker does not point anywhere
when executed for the *first* time. All subsequent executions don't exhibit
this error (currently, they hang, but that's another story).
My prompt is colored -- I need it, really! *None* of the =ls= results are
colored, though (in this above case: =ls ~/*.txt=).
Can we fix this somehow?
Test the following, and you'll see you need a colored prompt as well, if not
yet convinced:
#+begin_src sh :tangle .sva-bashrc
#*** Controlling the Prompt
# define some colors
RED='\e[1;31m'
GREEN='\e[1;32m'
NO_COLOR='\e[0m'
# my format of the prompt
function my_prompt_command ()
{
# colorful prompt, based on whether the previous command succeeded or not
if [[ $? -eq 0 ]]; then
HILIT=${GREEN}
else
HILIT=${RED}
fi
# replace the $HOME prefix by ~ in the current directory
if [[ $HOME == ${PWD:0:${#HOME}} ]]; then
NEWPWD="~${PWD:${#HOME}}"
else
NEWPWD=$PWD
fi
# how many characters of the $PWD should be kept
local pwd_max_length=15
if [[ ${#NEWPWD} -gt $pwd_max_length ]]; then
local pwd_offset=$(( ${#NEWPWD} - $pwd_max_length ))
NEWPWD="...${NEWPWD:$pwd_offset:$pwd_max_length}"
fi
# prompt character
if [[ $(whoami) = "root" ]]; then
local PROMPTCHAR="#"
else
local PROMPTCHAR=">"
fi
case $TERM in
dumb) # for Tramp?
setenv PS1 "[...@\h] ${NEWPWD}${PROMPTCHAR}"
;;
*)
setenv PS1 "\n\[${hilit}\]...@\h]
${NEWPWD}${PROMPTCHAR}\[${NO_COLOR}\]"
;;
esac
}
# shell prompt
setenv PROMPT_COMMAND my_prompt_command
echo ""
#+end_src
