0.47.0
|
||||
------
|
||||
- Replaced ["the default find command"][find] with a built-in directory traversal to simplify the code and to achieve better performance and consistent behavior across platforms.
|
||||
This doesn't affect you if you have `$FZF_DEFAULT_COMMAND` set.
|
||||
- Breaking changes:
|
||||
- Unlike [the previous "find" command][find], the new traversal code will list hidden files, but hidden directories will still be ignored
|
||||
- No filtering of `devtmpfs` or `proc` types
|
||||
- Traversal is parallelized, so the order of the entries will be different each time
|
||||
- You would wonder why fzf implements directory traversal anyway when it's a filter program following the Unix philosophy.
|
||||
But fzf has had [the traversal code for years][walker] to tackle the performance problem on Windows. And I decided to use the same approach on different platforms as well for the benefits listed above.
