[gentoo-user] Bash completion annoyance: escapes directory variables.

[gentoo-user] Bash completion annoyance: escapes directory variables.

[Jean-Baptiste Mestelan]

Hello all.


Now, I am unsure whether this is a feature, but:
when I tab-complete 'cd ' followed  an environment variable, bash
insists on escaping this variable.

ex: cd $<TAB> -> cd \$
Which means I end up typing for example
# cd \$DOC
and this is not resolved right.

If the variable path is not preceded by 'cd ' , bash completes it OK,
without escaping them.


Is there any way I can fix this behaviour ?
Thanks for your tips.

A system here does the same thing, another across town behaves  
"correctly".

(I don't actually have $DOC set on either, but `cd /` and then use  
autocomplete to `cd $HOME`, which is set.)

I don't know much about this, but I wonder if it may be related to  
some of Gentoo's 3rd-party Bash-completion features?

I have the same problem, and it also won't tab complete file names
inside back quotes as it used to.  If I have /tmp/fix-me-now, this
will simply beep.  It used to work.  I have gotten so used to gentoo
enhancements screwing up things like this that I won't waste time
filing bug reports or whining on the mailing liost until it has gone
several weeks without being fixed.  I figure sooner or later some dev
will notice it without haviung to ignore my whinings in the mean time.

$ emacs `cat /tmp/fix[TAB]

I have unmerged gentoo-bashcomp, but the problem remains. So, this
would put the blame on bash-completion.

I am using bash-completion-20060301. Following your message, I have
upgraded to latest (unstable) bash-completion-20081218
*and this solved the original problem* : tab-completion now does not
escape variables after 'cd' !

BUT (there had to be a 'but') ...
gentoo-bashcomp does not play well with this latest version, meaning
that after re-installing bashcomp, completion does not work after
gentoo commands (emerge, ebuild ...).


So, I think I will get back to bash-completion-20060301, and use cdb
instead of path variables.

Thanks for attention and suggestions.

Did you try using unstable gentoo-bashcomp too?

Yes, exact same result, meaning gentoo specific completion is disabled.
Does it work for you folks ?
