Do I have missed a non quoting version of <f-args> ?
Consider this example:
function! T(...)
for a in a:000
echom 'arg:'.string(a)
endfor
endfunction
------ 8< ------ 8< start test.vim < ------ 8< ------ 8< ------ 8<
command! -nargs=* -buffer TestAddSeven :call T(7,<f-args>)
command! -nargs=* -buffer Test2 :exec "call
T(7,".join([<f-args>],',').')'
TestAddSeven 4 'abc'
echo "Test 2"
Test2 3 'abc'

arg:7
arg:'4' << here you can see that all arguments get extra
extra quotes
arg:'''abc'''
Test 2
arg:7
arg:3
arg:'abc'
------ 8< ------ 8< ------ 8< ------ 8< ------ 8< ------ 8< ------ 8<
So is there a non quoting version of <f-args> which behaves like the
join([<f-args>],', ') part?
Marc
Here are the various ways in which a user-command may pass arguments:
:command arg1 arg2 arg3 arg4 arg5
<args> passes
arg1 arg2 arg3 arg4 arg5
<q-args> passes
"arg1 arg2 arg3 arg4 arg5"
<f-args> passes
"arg1","arg2","arg3","arg4","arg5"
I did my mistake here:
:command 'arg1 arg2'
<f-args> will pass
'''arg1' 'arg2'''
, not 'arg1 arg2'
So <f-args> works the way you'd expect but I have to pass the values
without quotes which don't bother vim here in no way..
Marc
In
:Command arg1 arg2
there are two arguments, and if the command expands to call Function(<f-args>)
you get
call Function('arg1','arg2')
In
:Command 'arg1 arg2'
there is one argument (whose _value_ contains quotes at beginning and end, and
a space in the middle) and the result (with the same command expansion as
above) is
call Function('''arg1 arg2''')
which is the same as
call Function("'arg1 arg2'")
Finally, in
:Command arg1\ arg2
there is one argument with a space in the middle, and it would invoke
call Function('arg1 arg2')
You can test it (IIUC) with
command Command -bar -nargs=* call Function(<f-args>)
function Function(...)
let n = a:0
echomsg "Number of arguments:" n
let i=1
while i <= n
echomsg "Argument" i . ": «" . a:{i} . "»"
i = i + 1
endwhile
endfunction
