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