After enable ivy-mode, when do (dired-do-copy), ivy candidate can not ignore ignored file

[zw963]

I expect ivy can ignore all files which i set in counsel-find-file-ignore-regexp, follwing is value.

"\\(?:#\\$\\|/\\\\\\.\\(?:\\(?:\\\\\\.\\)?\\$\\)\\|TAGS\\$\\|\\\\\\.elc\\$\\|\\^/\\(?:ssh:\\|tmp/\\\\\\?\\)\\|\\(?:locate\\\\\\.db\\|~\\)\\$\\)"

But it not work, when i do (dired-do-copy) on dired-mode, get following screenshot. ( i expect to ignore *.~undo-tree~)

counsel-find-file-ignore-regexp is specific to counsel-find-file, not dired-do-copy (or any other file-reading function that doesn't go through counsel-find-file).

I see, thank you, so, how to resolve it? I use helm too, it have a variable helm-boring-file-regexp-list, can take effect on any helm file buffer.

so, how to resolve it?

In vanilla Emacs there's completion-ignored-extensions, but I don't know whether Dired respects that, and I'm pretty sure Ivy doesn't.

So there are three possible and related resolutions:

1. Make file name reading more customisable in vanilla Emacs
2. Make file name reading more customisable in Ivy
3. Both 1 and 2 (e.g. by respecting upstream user options in Ivy)

Either way this sounds like the same underlying limitation / feature request as #2877.

I guess dired don't respect it. following is my completion-ignored_extensions config:

(".hi" ".o" "~" ".bin" ".lbin" ".so" ".a" ".ln" ".blg" ".bbl" ".elc" ".lof" ".glo" ".idx" ".lot" ".svn/" ".hg/" ".git/" ".bzr/" "CVS/" "_darcs/" "_MTN/" ".fmt" ".tfm" ".class" ".fas" ".lib" ".mem" ".x86f" ".sparcf" ".dfsl" ".pfsl" ".d64fsl" ".p64fsl" ".lx64fsl" ".lx32fsl" ".dx64fsl" ".dx32fsl" ".fx64fsl" ".fx32fsl" ".sx64fsl" ".sx32fsl" ".wx64fsl" ".wx32fsl" ".fasl" ".ufsl" ".fsl" ".dxl" ".lo" ".la" ".gmo" ".mo" ".toc" ".aux" ".cp" ".fn" ".ky" ".pg" ".tp" ".vr" ".cps" ".fns" ".kys" ".pgs" ".tps" ".vrs" ".pyc" ".pyo")

my ~undo-tree~ file ending with ~, it matched in this list, but not hidden.
