# What



One theme script to rule them all.



# Features



 - 400+ precompiled themes

 - [Terminal agnostic](#supported-terminals) (works on any terminal with OSC 4/11 support (e.g st, kitty, iterm))

 - Keeps history

 - [Script](#scripting-examples) friendly

 - Portable (a single <130k file with all 400 themes included)

 - Dark/Light filters so you can decide when you want to burn your retinas.

 - [Interactive](#demo) (requires [fzf](https://github.com/junegunn/fzf))

 - [Self modifying](#adding-themes) (can ingest kitty themes).

 - Small, self contained and POSIX compliant 



# Demo

# Why?



 - So you can easily switch themes inside of an open terminal.

 - So you can keep your shell's init file as the single source of truth.

 - So you can configure different themes for all your boxen (see [scripting](#scripting-examples)).

 - So you can configure st without recompiling it :P.

 - ~~So you can liberate your mind from the drudgery of the cubicle.~~.



# Installation



Simply put `theme.sh` somewhere in your path.



E.G



```

sudo curl -Lo /usr/bin/theme.sh 'https://git.io/JM70M' && sudo chmod +x /usr/bin/theme.sh

```



or (OSX)



```

sudo curl -Lo /usr/local/bin/theme.sh 'https://git.io/JM70M' && sudo chmod +x /usr/local/bin/theme.sh

```



# Examples



See `theme.sh -h` for a full list of options.



```

> theme.sh --dark --list



  zenburn

  gruvbox

  solarized-dark

  ...



> theme.sh zenburn

```



```

> theme.sh -i #Interactive theme selection (requires fzf)

```



Once you find something you like simply put



```

theme.sh 

```



in your `~/.bashrc`.



# Configuration



## Recommended `~/.bashrc`



To load the most recently selected theme automatically you can put



```

if command -v theme.sh > /dev/null; then

	[ -e ~/.theme_history ] && theme.sh "$(theme.sh -l|tail -n1)"



	# Optional



	#Binds C-o to the previously active theme.

	bind -x '"\C-o":"theme.sh $(theme.sh -l|tail -n2|head -n1)"'



	alias th='theme.sh -i'



	# Interactively load a light theme

	alias thl='theme.sh --light -i'



	# Interactively load a dark theme

	alias thd='theme.sh --dark -i'

fi

```



in your `~/.bashrc`.



## `~/.zshrc`

```

if command -v theme.sh > /dev/null; then

	[ -e ~/.theme_history ] && theme.sh "$(theme.sh -l|tail -n1)"



	# Optional



	# Bind C-o to the last theme.

	last_theme() {

		theme.sh "$(theme.sh -l|tail -n2|head -n1)"

	}



	zle -N last_theme

	bindkey '^O' last_theme



	alias th='theme.sh -i'



	# Interactively load a light theme

	alias thl='theme.sh --light -i'



	# Interactively load a dark theme

	alias thd='theme.sh --dark -i'

fi

```



## `~/.config/fish/config.fish`



```

if type -q theme.sh

	if test -e ~/.theme_history

	theme.sh (theme.sh -l|tail -n1)

	end



	# Optional

	# Bind C-o to the last theme.

	function last_theme

		theme.sh (theme.sh -l|tail -n2|head -n1)

	end



	bind \co last_theme



	alias th='theme.sh -i'



	# Interactively load a light theme

	alias thl='theme.sh --light -i'



	# Interactively load a dark theme

	alias thd='theme.sh --dark -i'

end

```



## Recommended `~/.vimrc`



```

colorscheme default

set notermguicolors

highlight Search ctermfg=0

```



The above makes vim play nicely with the stock terminal theme.



# Scripting Examples



## Example sudo/su wrapper.



The following shellrc snippet will set the theme to 'red-alert' when

su is used or sudo is run with a long running (> .2s) command. It assumes 

theme.sh has been used to set the current theme (as in the recommended

`~/.bashrc`).



```

su() {

	(

		INHIBIT_THEME_HIST=1 theme.sh red-alert

		trap 'theme.sh "$(theme.sh -l|tail -n1)"' INT

		env su "$@"

		theme.sh "$(theme.sh -l|tail -n1)"

	)

}



sudo() {

	(

		pid=$(exec sh -c 'echo "$PPID"')



		# If the command takes less than .2s, don't change the theme.

		# We could also just match on 'su' and ignore everything else,

		# but this also accomodates other long running commands

		# like 'sudo sleep 5s'. Modify to taste.



		(

				sleep .2s

				ps -p "$pid" > /dev/null && INHIBIT_THEME_HIST=1 theme.sh red-alert

		) &



		trap 'theme.sh "$(theme.sh -l|tail -n1)"' INT

		env sudo "$@"

		theme.sh "$(theme.sh -l|tail -n1)"

	)

}

```



## SSH Integration



Put the snippet in your shellrc:



and then



`~/.ssh_themes`:



```

host1: zenburn

host2: red-alert

...

```



```

ssh() {

	# A tiny ssh wrapper which extracts a theme from ~/.ssh_themes

	# and applies it for the duration of the current ssh command.

	# Each line in ~/.ssh_themes has the format:

	#     : .



	# Restoration relies on the fact that you are using theme.sh to manage

	# the current theme.  (that is, you set the theme in your bashrc.)



	# This can probably be made more robust. It is just a small demo

	# of what is possible.



	touch ~/.ssh_themes



	host="$(echo "$@"|awk '{gsub(".*@","",$NF);print $NF}')"

	theme="$(awk -vhost="$host" -F': *' 'index($0, host":") == 1 {print $2}' < ~/.ssh_themes)"



	if [ -z "$theme" ]; then

		env ssh "$@"

		return

	fi



	INHIBIT_THEME_HIST=1 theme.sh "$theme"

	trap 'theme.sh "$(theme.sh -l|tail -n1)"' INT

	env ssh "$@"

	theme.sh "$(theme.sh -l|tail -n1)"

}

```



You could also do something on the server side using `-p` for restoration, but

it requires a terminal which supports OSC query sequences and is less widely

supported.



## Adding Themes



If theme.sh is writable by the user executing it, kitty style theme configs can

be annexed directly to the script with `--add`. This allows you to grow your

own self contained theme file which you can scp to all your boxen. Just don't

forget to upstream your changes :P. See [CONTRIBUTING](CONTRIBUTING.md) for instructions

on adding themes to this repo.



E.G



```

curl -O 'https://raw.githubusercontent.com/dexpota/kitty-themes/master/themes/Solarized_Darcula.conf'

theme.sh --add Solarized_Darcula.conf

theme.sh Solarized_Darcula

```



If a theme with the same name already exists it will be overwritten.



Note that adding themes requires write access to the script and may require `sudo` for system-wide installations.



If you find a theme that is already not included in the script you are encouraged to submit a PR (see [CONTRIBUTING](CONTRIBUTING.md)).



# Supported Terminals



Below is a list of terminals on which theme.sh is known to work:

	

 - [kitty](https://github.com/kovidgoyal/kitty) (not KiTTY)

 - gnome-terminal

 - terminator

 - st

 - Terminal.app (osx)

 - iTerm2

 - alacritty

 - urxvt (non interactively unless the truecolor patch is applied)

 - any libvte based terminal



# Caveats



 - Requires a terminal that properly implements OSC 4/11.

 - Interactive mode also requires TRUECOLOR support (though the theme can still be set without it.)

 - May cause an imperceptible flash when you start your terminal.

 - Will not help you achieve enlightenment or improve your marriage.

 - May cause epilepsy.



# Known issues



 - Will not work in screen (tmux uses the same TERM variable)



# Acknowledgements

 A debt of gratitude is owed to these projects as well as well as those who

 contributed directly to the repo, and of course the theme authors themselves.
