## Writing message filter
-Message filter consists of arbitrary JavaScript code which must provide function with prototype `function filterMessage() { }`. This function must be fast and must return integer values which belong to enumeration [`FilteringAction`](https://github.com/martinrotter/rssguard/blob/master/src/librssguard/core/message.h#L83). For example, your function must return `2` to block the message which is subsequently NOT saved into database. For easier usage, RSS Guard 3.7.1+ offers named variables for this, which are called `MSG_ACCEPT` and `MSG_IGNORE`.

-Each message is accessible in your script via global variable named `msg` of type [`MessageObject`](https://github.com/martinrotter/rssguard/blob/master/src/librssguard/core/message.h#L118). Some properties are writable, thus allowing you to change contents of the message before it is written to DB. You can mark message important, parse its description or perhaps change author name!!!

The property is called `assignedLabels` and is array of `Label` objects. Each `Label` in the array offers these properties: `title` (title of the label), `color` (color of the label) and `customId` (account-specific ID of the label).
