xtext formatter questions, including linewraping, keywords replacing -

i have few questions formatter of xtext. i'm dealing sql-like language.

• i'm using 3 default setlinewrap() commands comments. insert space after sl_comment,

like

update plays set scores = scores - [ 12, 21 ] id = '123-afde'; // removes occurences of 12 , 21 scores  select * mytable t = now();  

become

update plays set scores = scores - [ 12, 21 ] id = '123-afde'; // removes occurences of 12 , 21 scores  select * mytable t = ( ); 

could remove space?

• how wrap @ specific place only if line long? tried setlinewrap(0, 1, 1) doesn't work.

for example

update table set = + 1 > 0;  update tablelongna set c = c + 1 c in (1, 2, 3, 4, 4, 5, 6, 7, 0, 7, 8); 

become

update table set = + 1 > 0;  update tablelongna set c = c + 1  c in (1, 2, 3, 4, 4, 5, 6, 7, 0, 7, 8); 

• i use setlinewrap(2).after(t_semicolon); , works fine usual case. batch query

like

begin batch     update ......;      update ......;  apply batch;  next query..... 

i try use setlinewrap(1).before(k_apply); overwrite doesn't work. can't use setnospace() or setnolinewrap() otherwise apply batch not have it's own line.

• can replace keyword upper case in formatter? ex. select * foo; select * foo;. looks apis can manipulating whitespaces/newlines?

• not sure it's problem or not, can't hot swap formatter in debug mode. such have quit eclipse instance , run again see change.
