"""Return list of 'kanj.txt' strings of those 'kanj' items
without a matching item in 'restrs'. "Maching" means two
items with the same value in the attribute named by 'key'.
if there are no items in 'restrs', and empty list is returned
(rather than a list of all 'kanji.txt' values). If every item
in 'kanj' has a matching item in 'restrs', a one-item list is
returned containing the string 'noXXX' where XXX is a derived
from the value of 'key'.
Each restr item will be passed to function 'quote_func' and
the string returned from that function is actually uwed top
build the return list.
This function is convenient for getting restriction text from
an entry for display. Assuming 'entr' is a jdb entry with a
non-empty list of kanji items in entr._kanj and rdng has been
set to a reading from entr._rdng:
restrtxt = ''
if hasattr (rdng, '_restr'):
restrtxt = ','.join (restrtxts (rdng._restr, 'kanj', entr._kanj))
if restrtxt: restrtxt = " (%s)" % restrtxt
print rdng.txt + restrtxt
It can also be used for stagr or stagk restrictions (although
one would not normally expect the ['noXXX'] form of output to
occur in these cases):
if hasattr (sens, '_stagr'):
restrtxt = ','.join (restrtxts (sens._stagr, 'rdng', entr._rdng))
If the "noXXX" case does not occur (as it would be expected not
to), the above is equivalent to:
if getattr (s,'_stagr', None): #Use getattr to filter out empty list case.
restrtxt = ','.join ([x.txt for x in
jdb.filt (rdng, ["rdng"], s._stagr, ["rdng"])])
