iris-dataset-countries

iris-dataset-countries

This repository contains a class and data of countries. The data is represented by countries.csv

Motivation

Even it’s relatively easy to import csv file in IRIS there could be errors.
This project helps to install with one ZPM command, that will create and compile a class and imports the data.

Sources and Licenses

The countries datataset is taken from the repo
It is licensed under the BSD 3-Clause “New” or “Revised” License

All other files of the repository are licensed under MIT License

Prerequisites

Make sure you have git and Docker desktop installed.

Installation

zpm “install dataset-countries”

Development

Clone/git pull the repo into any local directory

$ git clone https://github.com/intersystems-community/objectscript-docker-template.git

Open the terminal in this directory and run:

$ docker-compose up -d

If you want to change csv and update the class along with the data in the global uncomment the following lines in iris.script:

//zpm "install csvgen"
//d ##class(community.csvgen).GenerateFromURL("https://raw.githubusercontent.com/google/dspl/master/samples/google/canonical/countries.csv",",","dc.data.Country")

and comment the zpm module import line:

zpm "load /opt/irisbuild/ -v":1:1

csvgen will generate a new class and import the data.
you can export the class manually (right-click/Export in Server code view) - make sure then to move the generated file to a proper place in the directory (replace the previous dc/data/Country.cls)
and export globals with the following line:

d $System.OBJ.Export("dc.data.CountryD.GBL","/irisrun/repo/data/dc.data.CountryD.xml")

Comment csvgen and GenerateFromURL lines and uncomment the zpm line and rebuild the image to test (see below)whether the new data is in place with the package. If yes - well done, you’ve updated the package successfully!
