📺 television

A blazingly fast general purpose fuzzy finder for your terminal written in Rust.

The revolution will (not) be televised.

Television is a blazingly fast general purpose fuzzy finder TUI written in Rust.

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.

brew install alexpasmantier/television/television

curl -LO https://github.com/alexpasmantier/television/releases/download/0.5.0/television_0.5.0-1_amd64.deb
sudo dpkg -i television_0.5.0-1_amd64.deb

pacman -S television

• 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)

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

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

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

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.

Default keybindings are as follows:

These keybindings can be customized in the configuration file (see Customization).

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.

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.

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.

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.

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.

cd `tv git-repos`

open `tv`

code --goto `tv`

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)'

ls -1a | tv

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

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.

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

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