tbonsai

Ansipixels based reinterpretation of cbonsai (without looking at that program's source)

Using -leaves and regular terminal half block resolution

Same with -kitty using the Kitty Image protocol for high resolution image directly in the terminal background:

With optional -pot and -lines only and random colors:

You can also save high resolution images, for instance

tbonsai -trunk-width 6.25 -depth 7 -seed 42 -trunk-height 35 -save out80_7_35_mono.png

Produces

Use -kitty to see the high resolution image in your terminal that supports the Kitty Image protocol (kitty, ghostty, etc...)

Install

You can get the binary from releases

Or just run

CGO_ENABLED=0 go install fortio.org/tbonsai@latest  # to install (in ~/go/bin typically) or just
CGO_ENABLED=0 go run fortio.org/tbonsai@latest  # to run without install

or

brew install fortio/tap/tbonsai

or

docker run -ti fortio/tbonsai

Usage

Use -leaves to show leaves (winter tree otherwise)

Use -pot to show the pot for instance,

Use -auto 1s for a new tree every 1s without needing to press "T"

Use -rainbow for rainbow colors.

Use -exit and optionally redirect stdout (eg tbonsai -exit > tree.ansi) to render immediately one tree and exit without putting the terminal in raw mode.

Etc,... See help for other flags/options

tbonsai help

tbonsai 1.0.0 usage:
        tbonsai [flags]
or 1 of the special arguments
        tbonsai {help|envhelp|version|buildinfo}
flags:
  -auto interval
        If >0, automatically redraw a new tree at this interval and no user input is needed
  -color hex color
        Trunk base color as hex color (default with leaves: #654321 dark brown, branches gradually lighten with depth).
  -depth int
        Tree depth (number of branch levels) (default 6)
  -exit
        Exit immediately after drawing the tree once and saving ansi/kitty image if applicable
  -fps float
        Frames per second (ansipixels rendering) (default 60)
  -height int
        Height of the generated tree image when using Kitty mode or saving to PNG (default 720)
  -kitty
        Use Kitty graphics protocol for high-res images (resizable, regeneratable)
  -leaf-size float
        Leaf size multiplier (default 1)
  -leaves
        Draw leaves at branch endpoints
  -lines
        Use simple line drawing instead of polygon mode (default is polygon)
  -pot
        Draw the pot
  -rainbow
        Use random colors for each branch instead of depth-based brown gradient
  -save file name
        If set to a file name, saves one generated tree as a PNG image to that file and exits
  -seed uint
        Seed for random number generation. 0 means different random each run
  -spread float
        Branch angle spread multiplier (< 1.0 narrower, > 1.0 wider) (default 1)
  -truecolor
        Use true color (24-bit RGB) instead of 8-bit ANSI colors (default is true if COLORTERM is set)
  -trunk-height percentage
        Trunk height as percentage of available height (default 35)
  -trunk-width percentage
        Starting width of the trunk as percentage of image width (default 7)
  -width int
        Width of the generated tree image when using Kitty mode or saving to PNG (default 1280)
