An iso message bulk parser

Genat Iso Parser

An iso message bulk editor and parsor.

Usage:

ISO STREAMING

import the library
from genat_iso_parser.Iso import IsoDict, IsoFile, IsoStream

instantiate an instance of IsoStream
iso = IsoStream()

get current version
iso.iso_version

get supported versions
iso.supported_versions()

change any field value of your choice
iso.changed_fields = IsoDict({3: '001100'})
iso.changed_fields[2] = '9999999999999999999'

remove any number of fields of your choice
iso.removed_fields.add(7)
iso.removed_fields.update({3, 4})

add a field alomg with value
iso.added_fields.update({100: 'rywiujfbw8efhsdjkb'})
iso.added_fields[99] = 'isuhgghioadhfgioahdnf'

allow length of fields(if there is any) tobe printed to the output
iso.include_length = True

turn off fields length to be printed
iso.include_length = False

capture iso messages that come through stdin (default is 'json' the other one is 'iso') and output to stdout
iso.stream('iso')

stop streaming
iso.stop_stream()

ISO FILE

instantiate an instance of IsoFile, default version is 93
iso = IsoFile("your file here")

get current version
iso.iso_version

get supported versions
iso.supported_versions()

change any field value of your choice
iso.changed_fields = IsoDict({3: '001100'})
iso.changed_fields[2] = '1999999999999999999'

remove any number of fields of your choice
iso.removed_fields.add(5)
iso.removed_fields.update({3, 4})

add a field alomg with value
iso.added_fields = {100: 'rewayhfgiojsed'}
iso.added_fields[99] = 'isuhgghifgiosdjfoiaknoadhfgioahdnf'

allow length of fields(if there is any) tobe printed to the output
iso.include_length = True

turn off fields length to be printed
iso.include_length = False

produce csv file from the iso
csv_file = iso.to_csv()

produce iso file from the iso (might be useful for inspection of the iso)
iso_file = iso.to_iso()

produce json file from the iso
json_file = iso.to_json()

Iso format JSON file (ISO.json)

This part is only needed if there is a need to define your own ISO format file (Ex: defining your own ISO like ISO 20022)
This can be achieved using iso.custom_iso_version_file(file="your ISO format file", version="ISO version(Ex: 2)")
Additionally you can use the librariy's default ISO format as a sample by dowloading it using iso.download_iso_format_file()

Layout:

{
"A": {
"long": "B",
"short": "C",
"len": D,
"pad": E
},
.
.
.
}

• A -> field number
• B -> field long name
• C -> field short name
• D -> field length
• E -> length/size of leading field length for variable field lengths (Ex: field2 PAN has a pad of 2)

Sample:

{
"1": {
"long": "Secondary Bit Map",
"short": "BITMAP2",
"len": 16,
"pad": 0
},
"2": {
"long": "Primary Account Number",
"short": "PAN",
"len": 19,
"pad": 2
},
