GSS Engine ChangeLog

1.0.3-beta (May 24th 2014)

• Selectors other than id, class & tag can now be used in CCSS when surrounded by parans:

    (.section > article:not(.featured))[font-size] == 100;

• Support for plural selectors on either side of a constraint operator:

    .article[font-size] == .header[font-size];    
    
    @h |[.a][.b]| in(.cont) chain-width;
    
    .container {
      @h |[.itemA][.itemB]| in(::) chain-width;
    }

• 2D sugar props: size, position, center, intrinsic-size, top-left, top-right, bottom-left, bottom-right

1.0.2-beta (April 14th 2014)

• VGL: @grid-template empty zones can be defined with .
• VGL: added in() to @grid-template
• VGL: added h/v/top/right/bottom/left-gap() to @grid-template

VGL is still undocumented & under heavy dev.

1.0.1-beta (April 7th 2014)

• VFL: Point support
• VFL: shorthands @h & @v for @horizontal & @vertical
• VFL: outer-gap()
• VFL: Default containing element selector to ::this

New VFL Sugar

With the new VFL API sugar, the following:

    #container {
      @h |-[#a]-[#b]-| gap(10) outer-gap(20);
    }

is equivalent too:

    @horizontal |-20-[#a]-10-[#b]-20-| in(#container);    

VFL Points

Elements can be aligned relative to arbitrary positioned points using < Number | Constraint Variable | Element Property >

To horizontally align two buttons, each 8px from the center of the window:

/* VFL */
@h [#btn1]-<::window[center-x]>-[#btn2] gap(8);

/* Equivalent CCSS */
#btn1[right] + 8 == ::window[center-x];
::window[center-x] + 8 == #btn2[left];

Alignments can be positioned within points:

/* VFL */
@h <#wall[center-x]>-[#poster]-[#clock]-<::window[right])> gap(7);

/* Equivalent CCSS */
#wall[center-x] + 7 == #poster[left];
#poster[right] + 7 == #clock[left];
::window[right] - 7 == #clock[right];

Numbers, variables and arithmetic can be used:

/* VFL */
@v <100>[#box]<[row2]>;

/* Equivalent CCSS */
100 == #box[top];
#box[bottom] == [row2];
