Problem: command-line auto-completion hard with wildmenu
Solution: implement "noselect" wildoption value (Girish Palya)
When `noselect` is present in `wildmode` and 'wildmenu' is enabled, the
completion menu appears without pre-selecting the first item.
This change makes it easier to implement command-line auto-completion,
where the menu dynamically appears as characters are typed, and `<Tab>`
can be used to manually select an item. This can be achieved by
leveraging the `CmdlineChanged` event to insert `wildchar(m)`,
triggering completion menu.
Without this change, auto-completion using the 'wildmenu' mechanism is
not feasible, as it automatically inserts the first match, preventing
dynamic selection.
The following Vimscript snippet demonstrates how to configure
auto-completion using `noselect`:
```vim
vim9script
set wim=noselect:lastused,full wop=pum wcm=<C-@> wmnu
autocmd CmdlineChanged : timer_start(0, function(CmdComplete, [getcmdline()]))
def CmdComplete(cur_cmdline: string, timer: number)
var [cmdline, curpos] = [getcmdline(), getcmdpos()]
if cur_cmdline ==# cmdline # Avoid completing each character in keymaps and pasted text
&& !pumvisible() && curpos == cmdline->len() + 1
if cmdline[curpos - 2] =~ '[\w*/:]' # Reduce noise by completing only selected characters
feedkeys("\<C-@>", "ti")
set eventignore+=CmdlineChanged # Suppress redundant completion attempts
timer_start(0, (_) => {
getcmdline()->substitute('\%x00$', '', '')->setcmdline() # Remove <C-@> if no completion items exist
set eventignore-=CmdlineChanged
})
endif
endif
enddef
```
