📺 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
MacOS
brew install alexpasmantier/television/television
Debian-based (Debian, Ubuntu, Pop!_OS, Linux Mint, etc.)
curl -LO https://github.com/alexpasmantier/television/releases/download/0.5.2/television_0.5.2-1_amd64.deb
sudo dpkg -i television_0.5.2-1_amd64.deb
Arch Linux
pacman -S television
Binary (latest release)
- Download the latest release asset for your platform (e.g.
tv-vX.X.X-linux-x86_64.tar.gz
if you're on a linux x86 machine) - Unpack and copy to the relevant location on your system (e.g.
/usr/local/bin
on macos and linux for a global installation)
From source using cargo
:
Setup the latest stable Rust toolchain via rustup:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup update
Install television
:
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.
Matcher | Pattern |
---|---|
Fuzzy | foo |
Substring | 'foo / !foo to negate |
Prefix | ^foo / !^foo to negate |
Suffix | foo$ / !foo$ to negate |
Exact | ^foo$ / !^foo$ to negate |
For more information on the matcher behavior, see the nucleo-matcher documentation.
Keybindings
Default keybindings are as follows:
Key | Description |
---|---|
↑ / ↓ or Ctrl + n / p | Navigate through the list of entries |
Ctrl + u / d | Scroll the preview pane up / down |
Enter | Select the current entry |
Ctrl + y | Copy the selected entry to the clipboard |
Ctrl + r | Toggle remote control mode |
Ctrl + s | Toggle send to channel mode |
Esc | Quit the application |
These keybindings can be customized in the configuration file (see Customization).
Built-in Channels
The following 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.
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.
Terminal Emulator | Tested Platforms | Compatibility |
---|---|---|
Alacritty | macOS, Linux | ✅ |

Customization
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.
Platform | Value |
---|---|
Linux | $HOME/.config/television/config.toml |
macOS | $HOME/Library/Application Support/com.television/config.toml |
Windows | {FOLDERID_LocalAppData}\television\config |
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 $XDG_CONFIG_HOME/television/config.toml
.
You may also override these default paths by setting the TELEVISION_CONFIG
environment variable to the path of your desired configuration folder.
Example:
export TELEVISION_CONFIG=$HOME/.config/television
touch $TELEVISION_CONFIG/config.toml
Default Configuration
The default configuration file can be found in the repository's ./.config/config.toml.
