The command-line completion for the :echo command does not find
functions whose names begin with g:.
To demonstrate this, first start vim like this,
$ vim -N -u NONE -i NONE
then source a file containing the following.
let FooVar = "foo"
let g:BarVar = "bar"
function! FooFunc()
echo "foo"
endfunction
function! g:BarFunc()
echo "bar"
endfunction
Now, try completing each of those symbols after :echo with ^D
(Ctr-D).
:echo g:
g:BarVar g:FooVar
:echo Bar
BarFunc() BarVar
:echo Foo
FooFunc() FooVar
Note that the global variables are expanded following g: even if
they were not defined with g:, but that neither global function is
expanded following g: even if g: was in its name when defined.
I know the problem can be worked around, but when I see a function
defined with g: in its name, I'd like to be able to echo its return
value by typing the first few characters of its name as I see them
without having to think very much about it, as I can with global
variables.
I'm using vim 8.2.2340 in a terminal on an Ubuntu 20.04 system.
The problem also exists with vim 8.1.497. This works differently on
7.2.330, more as I would expect it to.
:echo g:
g:BarFunc() g:BarVar g:FooVar
:echo Bar
BarVar
:echo Foo
FooFunc() FooVar
I understand the desirability of expanding global symbols with or
without using the g: prefix, but I think including the g: prefix
should expand global function names as well as global variables.
I have not performed a git bisect to find the offending commit.
Regards,
Gary
