Hello list,
There's one situation in which I prefer zsh's behaviour over bash's...
Can anyone help me to make bash behave like zsh in this case? The fix
doesn't need to be a pure shell thing, there's no problem if I need
to patch the C source locally, I can keep a patched bash in ~/bin/, as
this is just for interactive use...
Here it is: when "verbose" mode is on (i.e., after "set -v") then
"source"ing (a.k.a. "."-ing) a script in zsh outputs all the script
lines and, as they are executed, also their output; doing the same in
bash outputs the script lines _minus the ones that belong to
here-documents_, plus their outputs. Here's an example:
/home/edrx(zsh)$ # Prepare the temporary script
/home/edrx(zsh)$ cat > /tmp/ee.sh <<'%%%'
> cd /tmp/
> rev <<'---'
> foo
> bar
> ---
> echo $[1+2]
> %%%
/home/edrx(zsh)$
/home/edrx(zsh)$ # Make 'ee' run it in verbose mode
/home/edrx(zsh)$ function ee () { set -v; . /tmp/ee.sh; set +v; }
/home/edrx(zsh)$
/home/edrx(zsh)$ # Run it - note how in zsh the here-doc lines
/home/edrx(zsh)$ # ARE echoed
/home/edrx(zsh)$ ee
cd /tmp/
rev <<'---'
foo
bar
---
oof
rab
echo $[1+2]
3
/tmp(zsh)$
/home/edrx(bash)$ # Prepare the temporary script
/home/edrx(bash)$ cat > /tmp/ee.sh <<'%%%'
> cd /tmp/
> rev <<'---'
> foo
> bar
> ---
> echo $[1+2]
> %%%
/home/edrx(bash)$
/home/edrx(bash)$ # Make 'ee' run it in verbose mode
/home/edrx(bash)$ function ee () { set -v; . /tmp/ee.sh; set +v; }
/home/edrx(bash)$
/home/edrx(bash)$ # Run it - note how in bash the here-doc lines
/home/edrx(bash)$ # are NOT echoed
/home/edrx(bash)$ ee
cd /tmp/
rev <<'---'
oof
rab
echo $[1+2]
3
/tmp(bash)$
Thanks in advance,

P.S.: here are some links that explain why I need to source
temporary scripts in verbose mode...
