vglue@ ( – rtyp rsub radd  ) minos2 “vglue-fetch”

xywh ( – rx0 ry0 rw rh  ) minos2

xywhd ( – rx ry rw rh rd  ) minos2

widget bounding box, starting at the left baseline point 

!resize ( rx ry rw rh rd –  ) minos2 “store-resize”

resize a widget 

!size ( –  ) minos2 “store-size”

let the widget self-determine its size 

dispose-widget ( –  ) minos2

get rid of a widget 

.widget ( –  ) minos2 “print-widget”

debugging: Print informations about the widget 

par-split ( rw –  ) minos2

split a paragraph by width rw 

resized ( –  ) minos2

Components are composed using a boxes&glue model similar to LaTeX, including paragraph breaking. For the sake of simplicity and portability, MINOS2 only supports a single window, and uses OpenGL for rendering.

MINOS2 furthermore supports animations with the animation class. A color index texture is used for different color schemes, and transition between neighboring schemes can also be animated. 

>animate ( rdelta addr xt –  ) minos2 “to-animate”

create a new animation, calling xt with stack effect ( addr r0..1 -- ) repeatedly, until the rdelta timeout expired; last call is always with argument 1e for the time.

You can create named color indexes and assign them color values for the currently active color scheme. 

color: ( rgba "name" –  ) minos2 “color-colon”

Create a (possibly shared) color index initialized with rgba 

new-color: ( rgba "name" –  ) minos2 “new-color-colon”

Create a unique color index initialized with rgba 

text-color: ( rgba "name" –  ) minos2 “text-color-colon”

Create a unique text color index initialized with rgba, the corresponding emoji color is set to white. 

text-emoji-color: ( rgbatext rgbaemoji "name" –  ) minos2 “text-emoji-color-colon”

Create a unique text color index initialized with rgbatext, the corresponding emoji color is set to rgbaemoji. 

fade-color: ( rgba1 rgba2 "name" –  ) minos2 “fade-color-colon”

Create a unique pair of text color index initialized with rgba1 and rgba2, the corresponding emoji color is set to white. By slowly shifting the index from one to the next index, the object will shift its color using a linear interpolation when redrawn. 

text-emoji-fade-color: ( rgbatext1 ~2 rgbaemoji1 ~2 "name" –  ) minos2 “text-emoji-fade-color-colon”

Create a unique pair of text color index initialized with rgbatext1 and ~2, the corresponding emoji color pair is set to rgbaemoji1 to ~2. By slowly shifting the index from one to the next index, the object will shift its color using a linear interpolation when redrawn. 

re-color ( rgba "name" –  ) minos2

assign the named color index "name" in the current color scheme with the value rgba. 

re-text-color ( rgba "name" –  ) minos2

assign the named text color index "name" in the current color scheme with the value rgba. 

re-emoji-color ( rgbatext rgbaemoji "name" –  ) minos2

assign the named text and emoji color index "name" in the current color scheme with the value rgbatext and rgbaemoji. 

re-fade-color ( rgba1 rgba2 "name" –  ) minos2

assign the named color index pair "name" in the current color scheme with the value rgba1 and rgba2. 

re-text-emoji-fade-color ( rgbatext1 ~2 rgbaemoji1 ~2 "name" –  ) minos2

assign the named color index pair "name" in the current color scheme with the value rgbatext1 and ~2 resp. rgbaemoji1 and ~2.

For a number of specific objects, there are early bound methods, that only work on these objects
