Basic: buffer

buffer​

The key features

  • Memory control and always safe with array limits
  • Common component to multiple purposes

The buffer is one of the key primitives of AnimationCPU. It is used to store and manipulate data and text. Everything uses a buffer. A buffer is always a 2D table with rows and columns, allowing you to store multiline text, easily attach any kind of data, and solve 80% of tasks more efficiently with 2D structures. If you're used to working with 1D arrays in other languages, you'll be pleasantly surprised by the possibilities a 2D buffer unlocks for vibe coding.

import​

_ @sys.obj;

buffer.new - create buffer​

 lines0=buffer.new(u0, 100,1000);

buffer.set.size - buffer resize​

buffer.set.size(u0, buf0,i, size);

buffer.dma - attach to dma​

buffer.dma(u0, dma0, buf,i);

buffer.clone - text clone​

text0=buffer.clone(u0, strings0,i);

str.clone - clone string to buffer​

str.clone(buf,i); -> buf

buffer get/set​

buffer.set - set value​

buffer.set(u0, buf,i,offs, v0);
buffer.set2(u0, buf,i,offs, v0,v1);
buffer.set3(u0, buf,i,offs, v0,v1,v2);
buffer.set4(u0, buf,i,offs, v0,v1,v2,v3);

buffer.get - get value​

v0:=buffer.get(u0, buf,i,offs);

buffer strings​

buffer.print.v0 - print value0​

 buffer.print.v(u0, lines0,0, date.start);

buffer.trim.left.eol - text trim​

query0 = buffer.trim.left.eol(text0);

buffer util​

buffer.shr - shift right​

buffer.shr(u0, buffer,i);

buffer geometry​

buffer.new.rect0 - new v2rect array​

buffer.new.rect0(dma, id, x,y, w,h);

buffer.add.rect0 - add to v2rect array​

buffer.add.rect0(dma, id, x,y, w,h);

to review​

buffer clear​

Buffer clear

  buffer.dma(u0, dma0, buf0,0);
  dma.strip.size(u0, dma0, 0);

buffer resize​

Buffer resize

  buffer.dma(u0, dma0, buf0,0);
  dma.strip.size(u0, dma0, 10);
