Unexpected reordering when using --scheme=history

[romkatv]

• I have read through the manual page (man fzf)
• I have the latest version of fzf
• I have searched through the existing issues

  • Linux
  • Mac OS X
  • Windows
  • Etc.
• Shell
  • bash
  • zsh
  • fish

Problem / Steps to reproduce

Run:

printf '%s\n' '/a/b' '/b' | fzf --scheme=history --query='/b'

Expected: no reordering of elements:

  /b
> /a/b
  2/2 ─────────────────
> /b

Actual: the elements are reordered:

  /a/b
> /b
  2/2 ─────────────────
> /b

Output of fzf --version: 0.46.1 (3c0a630).

Alternative reproduction steps:

1. Run: HISTFILE= FZF_DEFAULT_OPTS= bash --norc
2. Run: source shell/key-bindings.bash
3. Run: /b
4. Run: /a/b
5. Press: Ctrl-R

Expected: history entries are ordered by their number: 1 2 3.

Actual: history entries are out of order: 1 3 2.

Thanks for the report. Should be fixed now.

fzf was giving a higher score on / of /b because it is on the boundary, but it was giving zero bonus point to the second / of /a/b, which caused fzf to prefer the first /, resulting in a lower score in total. But this was a bug. / should be given the bonus point for non-word characters.

Thanks for the quick fix!

Do I understand correctly that --scheme=history is sufficient to disable reordering in all circumstances? If not, what is the right combination of commandline options to disable reordering?

No, if you do not want fzf to sort the list at all, you should use --no-sort option.

When you use the CTRL-R binding, you can press CTRL-R again to toggle sorting.

If you want to see the commands in chronological order, press CTRL-R again which toggles sorting by relevance

Thank you for the helpful answers.
