a small update for parser: it is now possible to parse so-called
"scripts" (only from 'string' type for now). sample script can
look like this one, which centers two buttons inside the panel,
keepeng equal button sizes:
===[cutline]===
var(stay)
panel.left = 0,
panel.top = 0,
panel.width = 80,
panel.height = 20;
// this is just a simple constants,
// use 'define' to avoid introducing new vars
define
button.hpadding = 4,
button.defheight = 10+6; // simple math
var
bt0.left, // default is 0
bt0.top,
<stay> bt0.width = 30,
<stay> bt0.height = button.defheight;
// oh, yeah, this will be calculated in-place
var
bt1.left,
bt1.top,
bt1.width,
bt1.height;
// some useful macros
define
panel.right = (panel.left+panel.width),
panel.bottom = (panel.top+panel.height),
bt0.right = (bt0.left+bt0.width),
bt0.bottom = (bt0.top+bt0.height),
bt1.right = (bt1.left+bt1.width),
bt1.bottom = (bt1.top+bt1.height);
// button-button placement and sizes
// default strength is <required>
bt1.left >= bt0.right+button.hpadding; // buttons padding
bt1.height == bt0.height; // same height
bt1.width == bt0.width; // same width
bt1.top == bt0.top; // same vertical position
// button-panel placement (this should center buttons)
// horizontal
bt0.left-panel.left == panel.right-bt1.right;
// vertical
bt0.top-panel.top == panel.bottom-bt0.bottom;
// print values (for debug mode)
print panel.left;
print panel.top;
print panel.width;
print panel.height;
print bt0.left;
print bt0.top;
print bt0.width;
print bt0.height;
print bt1.left;
print bt1.top;
print bt1.width;
print bt1.height;
===[cutline]===
there is no support for any kind of 'autobinding' variables to
class/struct properties yet, and parser code is awful. but the
whole thing is slowly growing…
anyway, it's really fun to play with various layout scripts. try
it yourself!
