Terminal screen saver for Zshell. Implements morphogenesis and Mandelbrot images. Written in pure Zshell (possible thanks to floating point numbers and to zsh/mathfunc module). Supports running external commands, for example cmatrix.

Screen saver will start after configured time, in last terminal in which a command has been executed.

Video – view on asciinema. You can resize the video by pressing Ctrl-+ or Cmd-+.

There are 4 zstyles:

zstyle ":morpho" screen-saver "zmorpho" # select screen saver "zmorpho"; available: zmorpho, zmandelbrot, zblank, pmorpho
                                        # this  can also be a command, e.g. "cmatrix"
zstyle ":morpho" arguments "-s"         # arguments given to screen saver program; -s - every key press ends
zstyle ":morpho" delay "290"            # 5 minutes before screen saver starts
zstyle ":morpho" check-interval "60"    # check every 1 minute if to run screen saver

To test screen savers run them directly from command line, e.g. issue "pmorpho".

The plugin is "standalone", which means that only sourcing it is needed. So to install, unpack zsh-morpho somewhere and add source {where-zsh-morpho-is}/zsh-morpho.plugin.zsh to zshrc.

If using a plugin manager, then Zplugin is recommended, but you can use any other too, and also install with Oh My Zsh (by copying directory to ~/.oh-my-zsh/custom/plugins).

Add zplugin load psprint/zsh-morpho to .zshrc. The plugin will be loaded next time you start Zsh. To update issue zplugin update psprint/zsh-morpho from command line.

Add zgen load psprint/zsh-morpho to .zshrc and issue a zgen reset (this assumes that there is a proper zgen save construct in .zshrc).

Add antigen bundle psprint/zsh-morpho to .zshrc. There also should be antigen apply.

1. cd ~/.oh-my-zsh/custom/plugins
2. git clone https://github.com/psprint/zsh-morpho.git
3. Add zsh-morpho to your plugin list
