Configure

Include/exclude
You can more finely control which HTML files are processed by specifying a regex for the include & exclude keys.
If a file matches both include and exclude the include will take precedence.
exports.plugins = {
preval:{
exclude: /thing.html$/,
, include: /something.html$/,
}
};Tokens
Tokens can be specified in your Brunch config.
Tokens may be static values or the results of a function. Dynamic tokens will be generated once per compile pass, and will have the same value for all files processed in each pass.
Tokens in templates can be accessed on the _ object.
<html><body>{{ _.BUILD_TIME }}</body></html>exports.plugins = {
preval:{
tokens: {
STATIC_VAL: 'Some value',
BUILD_TIME: ()=>(new Date).getTime() / 1000,
}
}
};Suppress Logging
Set log to false in your Brunch config to stop BrunchPreval from logging to the console during compilation.
exports.plugins = {
preval:{
log: false
}
};
