=46rom the TODOs on the knop_user type:

Add ->removedata to remove specific user data

I added this a while back to see if I could speed up my (very slow) users sessions: there were a lot of redundant fields been carried around. It didn't actually speed things up (still have to solve that, the speed issue may be inherent to Lasso 8 sessions), but I think it might be useful nonetheless to implement, comes just after 'getdata' tag. Seems to work and hasn't caused any problems so far.

// This is the standard getdata tag on about line 7700 of knop.lasso

define_tag: 'getdata', -description='Get field data from the data map',
-required='field';
if: (self -> 'data') >> #field;
return: (self -> 'data') -> (find: #field);
else;
(self -> '_debug_trace') -> insert(tag_name + ': ' + #field + ' not known');
/if;
/define_tag;

// This is the new removedata tag

define_tag: 'removedata', -description='Remove field from the data map',
-required='field';
if: (self -> 'data') >> #field;
(self -> 'data') -> (remove: #field);
else;
(self -> '_debug_trace') -> insert(tag_name + ': ' + #field + ' not known');
/if;
/define_tag;
