Class JsMessageExtractor
java.lang.Object
com.google.javascript.jscomp.JsMessageExtractor
Extracts messages and message comments from JS code.
Uses a special prefix (e.g. MSG_) to determine which variables
are messages. Here are the recognized formats:
var MSG_FOO = "foo";
var MSG_FOO_HELP = "this message is used for foo";
var MSG_BAR = function(a, b) {
return a + " bar " + b;
}
var MSG_BAR_HELP = "the bar message";
This class enforces the policy that message variable names must be unique across all JS files.
