 Key bindings for git objects
 ----------------------------

-I have [blogged](https://junegunn.kr/2016/07/fzf-git) about my fzf+git key
-bindings a few years ago. I'm going to show them here again, because they are
-seriously useful.
+Oftentimes, you want to put the identifiers of various Git object to the
+command-line. For example, it is common to write commands like these:
+
+```sh
+git checkout [SOME_COMMIT_HASH or BRANCH or TAG]
+git diff [SOME_COMMIT_HASH or BRANCH or TAG] [SOME_COMMIT_HASH or BRANCH or TAG]
+```
+
+[fzf-git.sh](https://github.com/junegunn/fzf-git.sh) project defines a set of
+fzf-based key bindings for Git objects. I strongly recommend that you check
+them out because they are seriously useful.

 CHANGELOG
 =========

+0.33.0
+------
+- Added `--scheme=[default|path|history]` option to choose scoring scheme
+    - (Experimental)
+    - We updated the scoring algorithm in 0.32.0, however we have learned that
+      this new scheme (`default`) is not always giving the optimal result
+    - `path`: Additional bonus point is only given the the characters after
+      path separator. You might want to choose this scheme if you have many
+      files with spaces in their paths.
+    - `history`: No additional bonus points are given so that we give more
+      weight to the chronological ordering. This is equivalent to the scoring
+      scheme before 0.32.0. This also sets `--tiebreak=index`.
+- ANSI color sequences with colon delimiters are now supported.
+  ```sh
+  printf "\e[38;5;208mOption 1\e[m\nOption 2" | fzf --ansi
+  printf "\e[38:5:208mOption 1\e[m\nOption 2" | fzf --ansi
+  ```
+- Support `border-{up,down}` as the synonyms for `border-{top,bottom}` in
+  `--preview-window`
+- Added support for ANSI `strikethrough`
+  ```sh
+  printf "\e[9mdeleted" | fzf --ansi
+  fzf --color fg+:strikethrough
+  ```
+
+0.32.1
+------
+- Fixed incorrect ordering of `--tiebreak=chunk`
+- fzf-tmux will show fzf border instead of tmux popup border (requires tmux 3.3)
+  ```sh
+  fzf-tmux -p70%
+  fzf-tmux -p70% --color=border:bright-red
+  fzf-tmux -p100%,60% --color=border:bright-yellow --border=horizontal --padding 1,5 --margin 1,0
+  fzf-tmux -p70%,100% --color=border:bright-green --border=vertical
+
+  # Key bindings (CTRL-T, CTRL-R, ALT-C) will use these options
+  export FZF_TMUX_OPTS='-p100%,60% --color=border:green --border=horizontal --padding 1,5 --margin 1,0'
+  ```
+
+0.32.0
+------
+- Updated the scoring algorithm
+    - Different bonus points to different categories of word boundaries
+      (listed higher to lower bonus point)
+        - Word after whitespace characters or beginning of the string
+        - Word after common delimiter characters (`/,:;|`)
+        - Word after other non-word characters
+      ```sh
+      # foo/bar.sh` is preferred over `foo-bar.sh` on `bar`
+      fzf --query=bar --height=4 << EOF
+      foo-bar.sh
+      foo/bar.sh
+      EOF
+      ```
+- Added a new tiebreak `chunk`
+    - Favors the line with shorter matched chunk. A chunk is a set of
+      consecutive non-whitespace characters.
+    - Unlike the default `length`, this scheme works well with tabular input
+      ```sh
+      # length prefers item #1, because the whole line is shorter,
+      # chunk prefers item #2, because the matched chunk ("foo") is shorter
+      fzf --height=6 --header-lines=2 --tiebreak=chunk --reverse --query=fo << "EOF"
+      N | Field1 | Field2 | Field3
+      - | ------ | ------ | ------
+      1 | hello  | foobar | baz
+      2 | world  | foo    | bazbaz
+      EOF
+      ```
+    - If the input does not contain any spaces, `chunk` is equivalent to
+      `length`. But we're not going to set it as the default because it is
+      computationally more expensive.
+- Bug fixes and improvements

Junegunn Choi	f0bfeba733	Add new tiebreak: 'chunk' Favors the line with shorter matched chunk. A chunk is a set of consecutive non-whitespace characters. Unlike the default `length`, this new scheme works well with tabular input. # length prefers item #1, because the whole line is shorter, # chunk prefers item #2, because the matched chunk ("foo") is shorter fzf --height=6 --header-lines=2 --tiebreak=chunk --reverse --query=fo << "EOF" N \| Field1 \| Field2 \| Field3 - \| ------ \| ------ \| ------ 1 \| hello \| foobar \| baz 2 \| world \| foo \| bazbaz EOF If the input does not contain any spaces, `chunk` is equivalent to `length`. But we're not going to set it as the default because it is computationally more expensive. Close #2285 Close #2537 - Not the exact solution to --tiebreak=length not taking --nth into account, but this should work. And the added benefit is that it works well even when --nth is not provided. - Adding a bonus point to the last character of a word didn't turn out great. The order of the result suddenly changes when you type in the last character in the word producing a jarring effect.	2022-08-02 21:48:19 +09:00
