Limit tokenized replacement to max length

Hi,

First of all thanks for all the good work on this module. The changes in the new version are great. I started to use tokens to create custom pages meta tags, in particular descriptions. On the nodewords settings page (admin/content/nodewords/settings) you can set a maximum length for the meta tag form fields.

Would it be useful to use the same length limit for token replacements or have a separate setting for that? If you use tokens based on CCK fields, the fields might allow longer text, e.g. I have a summary field for certain content types that I use in views for result pages. These fields are longer than the standard 350 character limit for the form fields. I would still like to use this CCK field as the metatag description. Right now it gets used in full length though. Maybe it would be good to implement an absolute maximum as well per metatag so that users do not accidentally include full text into the metatags. The logic would be:
- if no length limit is provided, shorten to the absolute maximum if the cck field length is longer than the maximum
- if length limit is provided that is shorter than the maximum, shorten to that limit if cck field length is longer than the provided limit.

Or am I supposed to create a custom token that does limit the content of the token to a desired length?

Thanks, J.
