# JPMarc
A library for using JPMARC in Elixir
## Installation
Add `jpmarc` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:jpmarc, github: "zuki/jpmarc"}]
end
```
## Usage
````elixir
alias JPMarc.Record
alias JPMarc.Leader
alias JPMarc.ControlField, as: CF
alias JPMarc.DataField, as: DF
alias JPMarc.SubField, as: SF
import JPMarc.MarkSigil
# Read MARC file and process every MARC record
for record <- JPMarc.parse_file("marc.dat") do
# Print a value of field 245, subfield a
IO.puts Record.subfield_value(record, "245", "a")
end
# Construct a JPMarc.Record
leader = %Leader{}
t001 = %CF{tag: "001", value: "1234"}
t003 = %CF{tag: "003", value: "JTNDL"}
t245a = %SF{code: "a", value: "Book title /"}
t245c = %SF{code: "c", value: "Yamada, Taro."}
t245 = %DF{tag: "245", ind1: "0", ind2: "0", subfields: [t245a, t245c]}
record = %Record{leader: leader, fields: [t001, t003, t245]}
# Construct a JPMarc.Record with ~m sigil
record = %Record{leader: %Leader{}, fields: [~m"001 1234", ~m"003 JTNDL", ~m"245 00 $a Book title / $b Yamada, Taro."]}
# Write records in MARC format
File.write("marc.dat", JPMarc.to_marc(record))
# Write records in MARCXML format
File.write("marc.xml", JPMarc.to_xml(record))
# Write records in Mark-in-json format
File.write("marc.json", JPMarc.to_json(record))
# Write records in Text format
File.write("marc.txt", Record.to_text(record))
````
## ~m Sigil
Covert string in Text MARC format to JPMarc.Record.
