reSTYLE is an eyeglass
framework for authoring configurable, composable UI patterns.
$ npm install --save-dev eyeglass-restyle
reSTYLE depends on eyeglass
being installed, so check out the eyeglass
installation docs
@import "restyle";
// optional configuration
@include restyle-config(...);
Take the following button styles...
.btn {
display: inline-block;
padding: 5px 10px;
font-weight: bold;
text-align: center;
vertical-align: middle;
border: 1px solid #3079ed;
border-radius: 2px;
background-color: #4787ed;
color: #fff;
cursor: pointer;
}
.btn:hover {
background-color: #357ae8;
border-color: #2f5bb7;
}
.btn[disabled] {
border-color: #3079ed;
background-color: #4787ed;
color: #fff;
opacity: 0.8;
cursor: default;
}
.btn.secondary {
border: 1px solid rgba(0, 0, 0, 0.1);
background-color: #f5f5f5;
color: #444444;
}
.btn.secondary:hover {
background-color: #e0e0e0;
color: #333333;
}
.btn.secondary[disabled] {
border-color: rgba(0, 0, 0, 0.1);
background-color: #f5f5f5;
color: #444444;
}
We can convert this to a reSTYLE definition as follows:
@import "restyle";
// define our UI pattern...
@include restyle-define(button, (
// Note that this is different from a Sass $variable. The Sass $variable will
// be evaluated at definition time, whereas the special restyle variable is
// evaluated at invocation time. This is important for the cascading
// behavior of modifiers/states
restyle-var(border-color): #3079ed,
display: inline-block,
padding: 5px 10px,
font-weight: bold,
text-align: center,
vertical-align: middle,
border: 1px solid restyle-var(border-color),
border-radius: 2px,
background-color: #4787ed,
color: #fff,
cursor: pointer,
restyle-states: (
hover: (
background-color: #357ae8,
border-color: #2f5bb7
),
disabled: (
border-color: restyle-var(border-color),
// note that we can reference other values within the definition
background-color: root(background-color),
color: root(color),
opacity: 0.8,
cursor: default
)
),
restyle-modifiers: (
secondary: (
restyle-var(border-color): rgba(0, 0, 0, 0.1),
border: 1px solid restyle-var(border-color),
background-color: #f5f5f5,
color: #444,
restyle-states: (
hover: (
background-color: #e0e0e0,
border-color: null,
color: #333
)
)
)
)
));
// register the states (note that this would be a "per app" configuration)
@include restyle-add-state((
hover: '&:hover',
disabled: '&[disabled]'
));
// ...
// now invoke it...
.btn {
@include restyle(button);
&.secondary {
@include restyle(secondary button);
}
}
This is probably a bit complex for everyone, so stay tuned for some additional elaboration.
