[stringtemplate-interest] Output string lengths..

[John Snyders]

So,  We could do the following $name; format="%50s"$, right? then
someone would have to make a string renderer, but that is easy.

Ter

The trouble is that for a single type there is one renderer so it must
handle all needed formats.
$name;format="pad,20"$ then later $name;format="upperCase"$ A renderer for
the format option can do whatever it wants with the argument but in some
cases it would pass it to String.format and other times it will do something
else. Trouble? Is this not a user/ system implementers problem?
  [John Snyders] Yes user implementation issue. Not a problem from the
desing of format option point of view.
  One could use a hash table to look up the operator names
  and default to String.format. Perhaps the implementor wants to support the
  following: pad(20,'x') or remove('abc')... or whatever...  they will do
that if
  the want to.


BTW String.format/Formater is new in Java 1.5. Yes I noted that. There are
other open source libraries available for doing something similar
  for earlier versions.... again that is a system implementers problem is it
not?
  [John Snyders] Yes

The renderer must be
able to distinguish one argument value from another. If you wanted to use
the format argument as the argument to String.format I guess you could check
to see that it contains a '%'.

The other issues I raised about where format applies Surely to the
attributes and the result of templates expansion?
  I may have missed the point.


and why can't options
take multiple parameters are still unanswered.
  I think I missed that... Can you point it out again.
