[SR-Users] Parameters list transformations comma and semi column conflict

[Seudin Kasumovic]

Hi Peter,

I tried transformation {pram.value,name['delimiter']} for 4.1.0-pre0:

$(*avp*(my_var){param.value, a, ';'})

and got parsing error:

0(32237) ERROR: pv [pv_trans.c:2386]: tr_parse_paramlist(): invalid
separator in transformation: value,a,';'}
0(32237) ERROR: <core> [pvapi.c:1586]: tr_lookup(): error parsing
[{param.value,a,';'}]
0(32237) ERROR: <core> [pvapi.c:972]: pv_parse_spec2(): bad tr in pvar name
"avp"
0(32237) ERROR: <core> [pvapi.c:998]: pv_parse_spec2(): invalid parsing in
[$(avp(my_var){param.value,a,';'})] at (4)

If set delimiter without quotes (documentation isn't clear for this), e.g.

$(*avp*(my_var){param.value, a, ;})

then no parsing complain. But, get same wrong results, for parameter value
not quoted if contains ','.

Is this expected behavior?

Regards,
Seudin
