For example, - -```sh -export FZF_DEFAULT_OPTS='--height 40% --layout=reverse --border' -``` - -### Search syntax - -Unless otherwise specified, fzf starts in "extended-search mode" where you can -type in multiple search terms delimited by spaces. e.g. `^music .mp3$ sbtrkt -!fire` - - - -If you don't prefer fuzzy matching and do not wish to "quote" every word, -start fzf with `-e` or `--exact` option. Note that when `--exact` is set, -`'`-prefix "unquotes" the term. - -A single bar character term acts as an OR operator. For example, the following -query matches entries that start with `core` and end with either `go`, `rb`, -or `py`. - -``` -^core go$ | rb$ | py$ -``` - -### Environment variables - -- `FZF_DEFAULT_COMMAND` -

-It will still work even when you're not on tmux, silently ignoring `-[pudlr]` -options, so you can invariably use `fzf-tmux` in your scripts. - -Alternatively, you can use `--height HEIGHT[%]` option not to start fzf in -fullscreen mode. - -```sh -fzf --height 40% -``` - -Key bindings for command-line ------------------------------ - -The install script will setup the following key bindings for bash, zsh, and -fish. - -- `CTRL-T` - Paste the selected files and directories onto the command-line - - The list is generated using `--walker file,dir,follow,hidden` option - - You can override the behavior by setting `FZF_CTRL_T_COMMAND` to a custom command that generates the desired list - - Or you can set `--walker*` options in `FZF_CTRL_T_OPTS` - - Set `FZF_CTRL_T_OPTS` to pass additional options to fzf - ```sh - # Preview file content using bat (https://github.com/sharkdp/bat) - export FZF_CTRL_T_OPTS=" - --walker-skip .git,node_modules,target - --preview 'bat -n --color=always {}' - --bind 'ctrl-/:change-preview-window(down|hidden|)'" - ``` - - Can be disabled by setting `FZF_CTRL_T_COMMAND` to an empty string when - sourcing the script -- `CTRL-R` - Paste the selected command from history onto the command-line - - If you want to see the commands in chronological order, press `CTRL-R` - again which toggles sorting by relevance - - Set `FZF_CTRL_R_OPTS` to pass additional options to fzf - ```sh - # CTRL-/ to toggle small preview window to see the full command - # CTRL-Y to copy the command into clipboard using pbcopy - export FZF_CTRL_R_OPTS=" - --preview 'echo {}' --preview-window up:3:hidden:wrap -

- The list is generated using `--walker dir,follow,hidden` option - - Set `FZF_ALT_C_COMMAND` to override the default command - - Or you can set `--walker-*` options in `FZF_ALT_C_OPTS` - - Set `FZF_ALT_C_OPTS` to pass additional options to fzf - ```sh - # Print tree structure in the preview window - export FZF_ALT_C_OPTS=" - --walker-skip .git,node_modules,target - --preview 'tree -C {}'" - ``` - - Can be disabled by setting `FZF_ALT_C_COMMAND` to an empty string when - sourcing the script - -If you're on a tmux session, you can start fzf in a tmux split-pane or in -a tmux popup window by setting `FZF_TMUX_OPTS` (e.g. `export FZF_TMUX_OPTS='-p80%,60%'`). -See `fzf-tmux --help` for available options. -

-Fuzzy completion for files and directories can be triggered if the word before -the cursor ends with the trigger sequence, which is by default `**`. - -- `COMMAND [DIRECTORY/][FUZZY_PATTERN]**` - -```sh -# Files under the current directory -# - You can select multiple items with TAB key -vim ** - -# Files under parent directory -vim ../** - -# Files under parent directory that match `fzf` -vim ../fzf** - -# Files under your home directory -vim ~/** - - -# Directories under current directory (single-selection) -cd ** - -# Directories under ~/github that match `fzf` -cd ~/github/fzf** -``` - -### Process IDs - -Fuzzy completion for PIDs is provided for kill command. - -```sh -# Can select multiple processes with or keys -kill -9 ** -``` - -### Host names - -For ssh and telnet commands, fuzzy completion for hostnames is provided. The -names are extracted from /etc/hosts and ~/.ssh/config. - -```sh -ssh ** -telnet ** -``` - -### Environment variables / Aliases - -```sh -unset ** -export ** -unalias ** -``` - -### Settings - -```sh -# Use ~~ as the trigger sequence instead of the default ** -export FZF_COMPLETION_TRIGGER='~~' - -# Options to fzf command -export FZF_COMPLETION_OPTS='--border --info=inline' - -# Use fd (https://github.com/sharkdp/fd) for listing path candidates. -# - The first argument to the function ($1) is the base path to start traversal -# - See the source code (completion.{bash,zsh}) for the details. -_fzf_compgen_path() { - fd --hidden --follow --exclude ".git" .

But you can enable it for other -commands as well by using `_fzf_setup_completion` helper function. - -```sh -# usage: _fzf_setup_completion path|dir|var|alias|host COMMANDS... -_fzf_setup_completion path ag git kubectl -_fzf_setup_completion dir tree -``` - -### Custom fuzzy completion - -_**(Custom completion API is experimental and subject to change)**_ - -For a command named _"COMMAND"_, define `_fzf_complete_COMMAND` function using -`_fzf_complete` helper. - -```sh -# Custom fuzzy completion for "doge" command -# e.g. doge ** -_fzf_complete_doge() { - _fzf_complete --multi --reverse --prompt="doge> " -- "$@" < <( - echo very - echo wow - echo such - echo doge - ) -} -``` - -- The arguments before `--` are the options to fzf. -- After `--`, simply pass the original completion arguments unchanged (`"$@"`). -- Then, write a set of commands that generates the completion candidates and - feed its output to the function using process substitution (`< <(...)`). - -zsh will automatically pick up the function using the naming convention but in -bash you have to manually associate the function with the command using the -`complete` command. - -```sh -[ -n "$BASH" ] && complete -F _fzf_complete_doge -o default -o bashdefault doge -``` - -If you need to post-process the output from fzf, define -`_fzf_complete_COMMAND_post` as follows. - -```sh -_fzf_complete_foo() { - _fzf_complete --multi --reverse --header-lines=3 -- "$@" < <( - ls -al - ) -} - -_fzf_complete_foo_post() { - awk '{print $NF}' -} - -[ -n "$BASH" ] && complete -F _fzf_complete_foo -o default -o bashdefault foo -``` - -Vim plugin ----------- - -See [README-VIM.md](README-VIM.md). - -Advanced topics ---------------- - -### Performance - -fzf is fast. Performance should not be a problem in most use cases. However, -you might want to be aware of the options that can affect performance. - -- `--ansi` tells fzf to extract and parse ANSI color codes in the input, and it - makes the initial scanning slower. So it's not recommended that you add it - to your `$FZF_DEFAULT_OPTS`. -- `--nth` makes fzf slower because it has to tokenize each line. -- `--with-nth` makes fzf slower as fzf has to tokenize and reassemble each - line. - -### Executing external programs - -You can set up key bindings for starting external processes without leaving -fzf (`execute`, `execute-silent`). - -```bash -# Press F1 to open the file with less without leaving fzf -# Press CTRL-Y to copy the line to clipboard and aborts fzf (requires pbcopy) -fzf --bind 'f1:execute(less -f {}),ctrl-y:execute-silent(echo {} | pbcopy)+abort' -``` - -See *KEY BINDINGS* section of the man page for details. - -### Turning into a different process - -`become(...)` is similar to `execute(...)`/`execute-silent(...)` described -above, but instead of executing the command and coming back to fzf on -complete, it turns fzf into a new process for the command. - -```sh -fzf --bind 'enter:become(vim {})' -``` - -Compared to the seemingly equivalent command substitution `vim "$(fzf)"`, this -approach has several advantages: - -* Vim will not open an empty file when you terminate fzf with - CTRL-C -* Vim will not open an empty file when you press ENTER on an empty - result -* Can handle multiple selections even when they have whitespaces - ```sh - fzf --multi --bind 'enter:become(vim {+})' - ``` - -To be fair, running `fzf --print0 | xargs -0 -o vim` instead of `vim "$(fzf)"` -resolves all of the issues mentioned. Nonetheless, `become(...)` still offers -additional benefits in different scenarios. - -* You can set up multiple bindings to handle the result in different ways - without any wrapping script - ```sh - fzf --bind 'enter:become(vim {}),ctrl-e:become(emacs {})' - ``` - * Previously, you would have to use `--expect=ctrl-e` and check the first - line of the output of fzf -* You can easily build the subsequent command using the field index - expressions of fzf - ```sh - # Open the file in Vim and go to the line - git grep --line-number . | - fzf --delimiter : --nth 3.. --bind 'enter:become(vim {1} +{2})' - ``` - -### Reloading the candidate list - -By binding `reload` action to a key or an event, you can make fzf dynamically -reload the candidate list. See https://github.com/junegunn/fzf/issues/1750 for -more details. - -#### 1. Update the list of processes by pressing CTRL-R - -```sh -ps -ef | - fzf --bind 'ctrl-r:reload(ps -ef)' \ - --header 'Press CTRL-R to reload' --header-lines=1 \ - --height=50% --layout=reverse -``` - -#### 2. Switch between sources by pressing CTRL-D or CTRL-F - -```sh -FZF_DEFAULT_COMMAND='find . -type f' \ - fzf --bind 'ctrl-d:reload(find . -type d),ctrl-f:reload(eval "$FZF_DEFAULT_COMMAND")' \ - --height=50% --layout=reverse -``` - -#### 3. Interactive ripgrep integration - -The following example uses fzf as the selector interface for ripgrep. We bound -`reload` action to `change` event, so every time you type on fzf, the ripgrep -process will restart with the updated query string denoted by the placeholder -expression `{q}`. Also, note that we used `--disabled` option so that fzf -doesn't perform any secondary filtering. - -```sh -: | rg_prefix='rg --column --line-number --no-heading --color=always --smart-case' \ - fzf --bind 'start:reload:$rg_prefix ""' \ - --bind 'change:reload:$rg_prefix {q} || true' \ - --bind 'enter:become(vim {1} +{2})' \ - --ansi --disabled \ - --height=50% --layout=reverse -``` - -If ripgrep doesn't find any matches, it will exit with a non-zero exit status, -and fzf will warn you about it. To suppress the warning message, we added -`|| true` to the command, so that it always exits with 0. - -See ["Using fzf as interactive Ripgrep launcher"](https://github.com/junegunn/fzf/blob/master/ADVANCED.md#using-fzf-as-interactive-ripgrep-launcher) -for more sophisticated examples. - -### Preview window - -When the `--preview` option is set, fzf automatically starts an external process -with the current line as the argument and shows the result in the split window. -Your `$SHELL` is used to execute the command with `$SHELL -c COMMAND`. -The window can be scrolled using the mouse or custom key bindings. - -```bash -# {} is replaced with the single-quoted string of the focused line -fzf --preview 'cat {}' -``` - -Preview window supports ANSI colors, so you can use any program that -syntax-highlights the content of a file, such as -[Bat](https://github.com/sharkdp/bat) or -[Highlight](https://gitlab.com/saalen/highlight): - -```bash -fzf --preview 'bat --color=always {}' --preview-window '~3' -``` - -You can customize the size, position, and border of the preview window using -`--preview-window` option, and the foreground and background color of it with -`--color` option. For example, - -```bash -fzf --height 40% --layout reverse --info inline --border \ -See the man page (`man fzf`) for the full list of options. - -More advanced examples can be found [here](https://github.com/junegunn/fzf/blob/master/ADVANCED.md). - -> [!WARNING] -> Since fzf is a general-purpose text filter rather than a file finder, **it is -> not a good idea to add `--preview` option to your `$FZF_DEFAULT_OPTS`**. -> -> ```sh -> # ********************* -> # ** DO NOT DO THIS! ** -> # ********************* -> export FZF_DEFAULT_OPTS='--preview "bat --style=numbers --color=always --line-range :500 {}"' -> -> # bat doesn't work with any input other than the list of files -> ps -ef | fzf -> seq 100 | fzf -> history | fzf -> ``` - -### Previewing an image - -fzf can display images in the preview window using one of the following protocols: - -* [Kitty graphics protocol](https://sw.kovidgoyal.net/kitty/graphics-protocol/) -* [iTerm2 inline images protocol](https://iterm2.com/documentation-images.html) -* [Sixel](https://en.wikipedia.org/wiki/Sixel) - -See [bin/fzf-preview.sh](bin/fzf-preview.sh) script for more information. - -```sh -fzf --preview 'fzf-preview.sh {}' -``` - -### Respecting `.gitignore` - -You can use [fd](https://github.com/sharkdp/fd), -[ripgrep](https://github.com/BurntSushi/ripgrep), or [the silver -searcher](https://github.com/ggreer/the_silver_searcher) to traverse the file -system while respecting `.gitignore`. - -```sh -# Feed the output of fd into fzf -fd --type f --strip-cwd-prefix | fzf - -# Setting fd as the default source for fzf -export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix' - -# Now fzf (w/o pipe) will use the fd command to generate the list -fzf - -# To apply the command to CTRL-T as well -export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND" -``` - -If you want the command to follow symbolic links and don't want it to exclude -hidden files, use the following command: - -```sh -export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix --hidden --follow --exclude .git' -``` - -### Fish shell - -`CTRL-T` key binding of fish, unlike those of bash and zsh, will use the last -token on the command-line as the root directory for the recursive search. For -instance, hitting `CTRL-T` at the end of the following command-line - -```sh -ls /var/ -``` - -will list all files and directories under `/var/`. - -When using a custom `FZF_CTRL_T_COMMAND`, use the unexpanded `$dir` variable to -make use of this feature. `$dir` defaults to `.` when the last token is not a -valid directory. Example: - -```sh -set -g FZF_CTRL_T_COMMAND "command find -L \$dir -type f 2> /dev/null | sed '1d; s#^\./##'" -``` - -### fzf Theme Playground - -[fzf Theme Playground](https://vitormv.github.io/fzf-themes/) created by -[Vitor Mello](https://github.com/vitormv) is a webpage where you can -interactively create fzf themes. - diff --git a/testdata/replace02.md b/testdata/replace02.md new file mode 100644 index 0000000..b725774 --- /dev/null +++ b/testdata/replace02.md @@ -0,0 +1,18 @@ +# Title + +```bash +echo 'foobar' \ +∙ | grep \ +∙ -E \ +∙ --color 'foo' +``` + +| foo | bar | +| --- | --- | +| baz | bim | + +```bash +echo 'foobar' \ +∙ | grep \ +∙ --color 'foo' +``` diff --git a/testdata/replace_want02.md b/testdata/replace_want02.md new file mode 100644 index 0000000..9dd9359 --- /dev/null +++ b/testdata/replace_want02.md @@ -0,0 +1,17 @@ +# Title + +```bash +echo 'foobar' \ +∙ | grep \ +∙ --color 'foo' +``` + +| foo | bar | +| ----- | --- | +| bazoo | bim | + +```bash +echo 'foobar' \ +∙ | grep \ +∙ --color 'foo' +```
