** Features
- Search and play videos with one command
- Interactively select a video from a list
- Download a video to the current working directory
- Search and play videos with one command
- Interactively select a video from a list
- Download a video to the current working directory
There is a =--music= flag, so you can substitute /video/ with /song/ in the above list.
There is a =--music= flag, so you can substitute /video/ with /song/ in the above list.
** Execution
This project is a [[https://nixos.wiki/wiki/Flakes][Nix flake]].
If you have a recent *Nix* version and *flakes* are enabled, you can execute the script via:
This project is a [[https://nixos.wiki/wiki/Flakes][Nix flake]].
If you have a recent [[https://nixos.org/][Nix]] version and *Flakes* are enabled, you can execute the script via:
#+begin_example sh
nix run github:Deleh/tyt -- --help
#+end_example
: nix run github:Deleh/tyt -- --help
If you are not running the [[https://nixos.org/][Nix]] package manager, you should definitely try it out.
If not you can clone the repo, make sure the dependencies listed below are fulfilled and execute /tyt/ manually:
Anyway, this is just a shell script so clone the repo, make sure the dependencies listed below are fulfilled and there you go:
#+begin_example sh
./tyt --help
#+end_example
: ./tyt --help
** Dependencies
If you are running tyt as *Nix flake* you don't have to care about dependencies.
A mpv version with scripts is used by default, this enables *MPRIS support* while playback and *skipping sponsored segments* of videos.

** Usage
#+begin_example text
Usage:
tyt [options] "<quoted_query>"
#+begin_example
Usage: tyt [OPTIONS] QUERIES ... [OPTIONS]
Options:
-a* --alternative Play an alternative video (e.g. -aaa for third alternative)
-h --help Show this help message
-i --interactive Interactive mode (overrides --alternative)
-m --music Play only the audio track
-s --save Save video (or audio if -m is provided) to the current directory
Play YouTube videos from the command line in a convenient way.
Examples:
OPTIONS
-h, --help Show this help message
-a*, --alternative Play an alternative video (e.g. -aaa for third
alternative)
-d, --download Download video (or audio if -m is provided) to the current
directory
-i, --interactive Interactive mode (overrides --alternative)
-m, --music Play only the audio track
Search for "Elephants Dream" and play the video:
tyt "Elephants Dream"
Search for "The Beatles - Yellow Submarine" and play only the music:
tyt -m "The Beatles - Yellow Submarine"
Search for "Elephants Dream" interactively and download the selected video:
tyt -i -s "Elephants Dream"
#+end_example
** Script
*** Dependencies
On the start of the script, it is checked if the dependencies are fulfilled.
#+begin_src bash
missing_dependencies=false
if ! command -v jq &> /dev/null
then
echo -ne "\e[1mjq\e[0m was not found, please install it\n"
missing_dependencies=true
fi
if ! command -v mpv &> /dev/null
then
echo -ne "\e[1mmpv\e[0m was not found, please install it\n"
missing_dependencies=true
fi
if ! command -v youtube-dl &> /dev/null
then
echo -ne "\e[1myoutube-dl\e[0m was not found, please install it\n"
missing_dependencies=true
fi
if [ "$missing_dependencies" = true ]
then
exit 1
fi
#+end_src
*** Usage
This function prints the usage of the script.
#+begin_src bash
function print_usage {
echo "Usage:"
echo " tyt [options] \"<quoted_query>\""
echo ""
echo "Options:"
echo " -a* --alternative Play an alternative video (e.g. -aaa for third alternative)"

*** Arguments
At first we parse the arguments.
We have the following flags:
- =-a* | --alternative= :: Alternative video; You can parse any amount of alternatives (e.g. =-aaa=)
- =-h | --help= :: Show a help message
- =-i | --interactive= :: Interactive mode; Shows the first 10 results and queries for a selection; If this flag is set, =-a= is ignored
- =-m | --music= :: Play only the audio track of the video
- =-s | --save= :: Save the video (or audio if =-m= is set) to the current directory
Additionally we have exacly one mandatory quoted string as query.
#+begin_src bash
alternative=0
format="flac"
interactive=false
music=false
save=false
help=false
for arg in "$@"

case $arg in

#+end_src
*** Greeter
If the arguments match, print a greeter.
Another greeter is printed if the flag =-m= is set.
Make sure your terminal emulator supports Unicode to see the notes.
#+begin_src bash
if [ "$music" = false ]
then
echo -ne "\n \e[1m\ /\e[0m\n"

*** Get URL and other data
To play a video, we need to get a valid URL.
Since there are sometimes parsing errors of the JSON response, we use an endless loop to try until we get a valid response.
The first /n/ URLs are saved if an alternative download is requested.
#+begin_src bash

*** Interactive selection
If the interactive flag is present, show the first ten results and query for a video to play.

*** Play or save video
Finally the video is played via mpv or saved via youtube-dl.
If the =-m= flag is set, only the audio track is played or saved.
In interaction mode, another video is queried to be played.
