tmux-fingers

tmux-fingers: copy pasting with vimium/vimperator like hints.

Usage

Press ( prefix + F ) to enter [fingers] mode, it will highlight relevant stuff in the current pane along with letter hints. By pressing those letters, the highlighted match will be yanked. Less keystrokes == profit!

Relevant stuff:

• File paths
• git SHAs
• numbers ( 4+ digits )
• urls
• ip addresses

It also works on copy mode, but requires tmux 2.2 or newer to properly take the scroll position into account.

Additionally, you can install tmux-yank for system clipboard integration.

Key shortcuts

While in [fingers] mode, you can use the following shortcuts:

• a-z: yank a highlighted hint.
• SPACE: toggle compact hints ( see @fingers-compact-hints ).
• CTRL + c: exit [fingers] mode
• ESC: exit help or [fingers] mode
• ?: show help.

Requirements

• tmux 2.1+ ( 2.2 recommended )
• bash 4+
• gawk

Installation

Using Tmux Plugin Manager

Add the following to your list of TPM plugins in .tmux.conf:

set -g @plugin 'Morantron/tmux-fingers'

@fingers-key

default: F

Customize how to enter fingers mode. Always preceded by prefix: prefix + @fingers-key

For example:

set -g @fingers-key F

@fingers-patterns-N

You can also add additional patterns if you want more stuff to be highlighted:

set -g @fingers-pattern-0 'git rebase --(abort|continue)'
set -g @fingers-pattern-1 'yolo'
.
.
.
set -g @fingers-pattern-50 'whatever'

Patterns are case insensitive, and grep's extended syntax ( ERE ) should be used. man grep for more info.

If the introduced regexp contains an error, an error will be shown when invoking the plugin.

@fingers-copy-command

default: NONE

By default tmux-fingers will just yank matches using tmux clipboard ( or tmux-yank if present ).

If you still want to set your own custom command you can do so like this:

set -g @fingers-copy-command 'xclip -selection clipboard'

This command will also receive the following:

• IS_UPPERCASE: environment variable set to 1 or 0 depending on how the hint was introduced.
• HINT: environment variable the selected letter hint itself ( ex: q, as, etc... ).
• stdin: copied text will be piped to @fingers-copy-command.

@fingers-copy-command-uppercase

default: NONE

Same as @fingers-copy-command but it's only triggered when input is introduced in uppercase letters.

For example, this open links in browser when holding SHIFT while selecting the hint:

set -g @fingers-copy-command-uppercase 'xargs xdg-open'

@fingers-compact-hints

default: 1

By default tmux-fingers will show hints in a compact format. For example:

/path/to/foo/bar/lol

with @fingers-compact-hints set to 1:

awath/to/foo/bar/lol

with @fingers-compact-hints set to 0:

/path/to/foo/bar/lol [aw]

( pressing aw would yank /path/to/foo/bar/lol )

While in [fingers] mode you can press SPACE to toggle compact mode on/off.

Compact mode is preferred because it preserves the length of lines and doesn't cause line wraps, making it easier to follow.

However for small hints this can be troublesome: a path as small as /a/b would have half of its original content concealed. If that's the case you can quickly toggle off compact mode by pressing SPACE.

@fingers-hint-position

default: "left"

Control the position where the hint is rendered. Possible values are "left" and "right".

@fingers-hint-position-nocompact

default: "right"

Same as above, used when @fingers-compact-hints is set to 0.

@fingers-hint-format

default: "#[fg=yellow,bold]%s"

You can customize the colors using the same syntax used in .tmux.conf for styling the status bar. You'll need to include the %s placeholder in your custom format, that's where the content will be rendered.

Check all supported features here.

@fingers-hint-format-nocompact

default: "#[fg=yellow,bold][%s]"

Same as above, used when @fingers-compact-hints is set to 0.

@fingers-highlight-format

default: "#[fg=yellow,bold,dim]%s"

Custom format for the highlighted match. See @fingers-hint-format for more details.

@fingers-highlight-format-nocompact

default: "#[fg=yellow,bold,dim]%s"

Same as above, used when @fingers-compact-hints is set to 0.

Acknowledgements and inspiration

This plugin is heavily inspired by tmux-copycat ( tmux-fingers predefined search are copycatted :trollface: from tmux-copycat ).

Kudos to bruno- for paving the way to tmux plugins! 👏 👏
