Logo2PNG

This is a program that converts logo(UCBLogo / Berkeley Logo) files to PNG images.

Usage

go run . logo_commands.txt 
# or `go build` and run `logo2png logo_commands.txt`

Then, you will get a PNG file named logo_commands.png under the same directory.

Example

setpencolor [255 0 0]
setpentype circle
setpensize [16 5]
fd 200
rt 90
fd 50
rt 90
fd 200
rt 90
fd 50
rt 90
pu
rt 45
fd 60
fill [55 35 45]

Output:

Supported Commands

• setpencolor
• setpensize
• fd
• bk
• rt
• pu
• pd
• fill

Customized Commands

• setpencolor is now supporting RGBA values. Alpha value is the forth value in the list. For example, [255 0 0 255] is red with full opacity.
• setpentype (New). You can do setpentype circle or setpentype square. The default is square(same as traditional logo).

Unsupported Commands (TODO)

• repeat, repcount
• setscreencolor
• setxy
• home
• to, end (define a procedure)
• cs (clearscreen, probably not needed)
• label (I will want it)

They are not supported yet, just because I didn't need them. I may add them if I need them.

Architectual Todo

• Make use of a lexer and token parser

Why I made this

I fill so lazy to draw images in mspaint or Photoshop when I am making a game. So I wanted to have a simple tool to draw images with code. I found that Logo is a good tool for this purpose instead of other very complex syntaxes like Processing, SVG, etc. So I made this tool to convert Logo commands to PNG images.
