/** |
|
Phrase view which trims the 'input:name' and uses ALL BUT the last token. |
|
|
|
eg. if the input was "100 foo str", then 'input:name' would only be '100 foo' |
|
note: it is assumed that the rest of the input is matched using another view. |
|
|
|
code notes: this view makes a copy of the $vs object in order to change their |
|
values without mutating the original values, which may be expected in their |
|
unaltered form by other views. |
