📺 television

A blazingly fast general purpose fuzzy finder TUI.

The revolution will (not) be televised.

About

Television is a blazingly fast general purpose fuzzy finder TUI.

It is inspired by the neovim telescope plugin and is designed to be fast, efficient, simple to use and easily extensible. It is built on top of tokio, ratatui and the nucleo matcher used by the helix editor.

Installation

brew install television

pacman -S television

curl -LO https://github.com/alexpasmantier/television/releases/download/0.6.2/television_0.6.2-1_amd64.deb
sudo dpkg -i television_0.6.2-1_amd64.deb

pixi global install television

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup update

cargo install --locked television

Usage

tv [channel] #[default: files] [possible values: env, files, git-repos, text, alias]

By default, television will launch with the files channel on.

Matcher behavior

television uses a fuzzy matching algorithm to filter the list of entries. The algorithm that is used depends on the input pattern that you provide.

For more information on the matcher behavior, see the nucleo-matcher documentation.

Keybindings

Default keybindings are as follows:

These keybindings are all configurable (see Configuration).

📺 Built-in Channels

The following built-in channels are currently available:

• Files: search through files in a directory tree.
• Text: search through textual content in a directory tree.
• GitRepos: search through git repositories anywhere on the file system.
• Env: search through environment variables and their values.
• Alias: search through shell aliases and their values.
• Stdin: search through lines of text from stdin.

🍿 Cable channels

Tired of broadcast television? Want to watch your favorite shows on demand? television has you covered with cable channels. Cable channels are channels that are not built-in to television but are instead provided by the community.

You can find a list of available cable channels on the wiki and even contribute your own!

Installing cable channels

Installing cable channels is as simple as creating provider files in your configuration folder.

A provider file is a *channels.toml file that contains cable channel prototypes defined as follows:

my-custom-channels.toml

[[cable_channel]]
name = "Git log"
source_command = 'git log --oneline --date=short --pretty="format:%h %s %an %cd" "$@"'
preview_command = 'git show -p --stat --pretty=fuller --color=always {0}'

[[cable_channel]]
name = "My dotfiles"
source_command = 'fd -t f . $HOME/.config'
preview_command = 'bat -n --color=always {0}'

This would add two new cable channels to television available using the remote control mode:

[[cable_channel]]
name = "Disney channel"
source_command = 'echo "one:two:three:four" && echo "five:six:seven:eight"'
preview_command = 'echo {2}'
preview_delimiter = ':'
# which will pass "three" and "seven" to the preview command

Design (high-level)

Channels

Television's design is primarily based on the concept of Channels. Channels are just structs that implement the OnAir trait.

As such, channels can virtually be anything that can respond to a user query and return a result under the form of a list of entries. This means channels can be anything from conventional data sources you might want to search through (like files, git repositories, remote filesystems, environment variables etc.) to more exotic implementations that might inclue a REPL, a calculator, a web browser, search through your spotify library, your email, etc.

Television provides a set of built-in Channels that can be used out of the box (see Built-in Channels). The list of available channels will grow over time as new channels are implemented to satisfy different use cases.

Transitions

When it makes sense, Television allows for transitions between different channels. For example, you might want to start searching through git repositories, then refine your search to a specific set of files in that shortlist of repositories and then finally search through the textual content of those files.

This can easily be achieved using transitions.

Previewers

Entries returned by different channels can be previewed in a separate pane. This is useful when you want to see the contents of a file, the value of an environment variable, etc. Because entries returned by different channels may represent different types of data, Television allows for channels to declare the type of previewer that should be used. Television comes with a set of built-in previewers that can be used out of the box and will grow over time.

Recipes

Here are some examples of how you can use television to make your life easier, more productive and fun. You may want to add some of these examples as aliases to your shell configuration file so that you can easily access them.

NOTE: most of the following examples are meant for macOS. Most of the commands should work on Linux as well, but you may need to adjust them slightly.

CDing into git repo

cd `tv git-repos`

Opening file in default editor

open `tv`

VSCode:

code --goto `tv`

Vim

vim `tv`

at a specific line using the text channel

tv text | xargs -oI {} sh -c 'vim "$(echo {} | cut -d ":" -f 1)" +$(echo {} | cut -d ":" -f 2)'

Inspecting the current directory

ls -1a | tv

Terminal Emulators Compatibility

Here is a list of terminal emulators that have currently been tested with television and their compatibility status.

Configuration

You may wish to customize the behavior of television by providing your own configuration file. The configuration file is a simple TOML file that allows you to customize the behavior of television in a number of ways.

Here are default locations where television expect the configuration files to be located for each platform:

NOTE: on either platform, XDG_CONFIG_HOME will always take precedence over default locations if set, in which case television will expect the configuration file to be in $XDG_CONFIG_HOME/television/config.toml.

You may also override these default paths by setting the TELEVISION_CONFIG environment variable to the path of your desired configuration folder.

export TELEVISION_CONFIG=$HOME/.config/television
touch $TELEVISION_CONFIG/config.toml

Default Configuration

The default configuration file can be found in the repository's ./.config/config.toml.
