[librecat-dev] bind for appending repeating MARC fields

[Jason Loeffler]

Just following up with my own (potential) solution:

Where list.csv is:

_id,value
1234,"item.1,item.2,item.3"

and the fix is:

# 952
lookup(somefield,list.csv)
split_field(somefield,",")

do list(path:somefield,var:c)
  marc_add('952',ind1,' ',ind2,' ',o,$.c)
end

Seems to do the trick.

Unfortunately, when trying to create a hashmap where the fix is:

catmandu convert CSV to Null --fix 'do
hashmap(exporter:CSV,join:",");nothing();end' < lookup.csv

and the lookup.csv is:

key,value
1234,"item.1"
1234,"item.2"
1234,"item.3"

I get:

Oops! Syntax error in your fixes...

Expected end of input on line 1 at:
do hashmap(exporter:CSV,join:",");nothing();end
^

Opening an issue on Github.
