Integrate Python into CL and RPG on IBM i

python trainingPython has been gaining momentum for building utility applications on IBM i, such as creating/reading Excel files, data transfer, process automation, calling REST APIs such as Salesforce and ServiceNow, and application monitoring.

Although some have said that Python would become the “new CL,” one limitation remains. While Python can easily call CL, RPG, and COBOL programs, calls in the other direction—from CL, RPG or COBOL to Python—required extra effort.

In this post we will introduce you to the PYRUN command, from Richard Schoen’s open source PythonOniLibrary (https://github.com/richardschoen/PythonOniLibrary), which makes it easy for traditional CL and RPG programs to call Python utilities and use their output. Read more

Free encryption for Node.js on IBM i

Let's EncryptWhen you browse a secure web site or API whose address starts with “https,” what makes the site secure? The site uses a special certificate, provided by a trusted Certificate Authority (CA), to prove that it is legitimate. Until recently, IT shops had to pay for these certificates and generate them manually.

In the last few years, Let’s Encrypt has earned the thanks of technology professionals. Let’s Encrypt, a CA run for the public’s benefit, offers certificates at no charge, along with scripts to generate and regenerate certificates as needed, reducing the effort of keeping certificates up to date, and keeping sites secure.

Sneak Peek at Plans for ILEditor 2

worksofbarryI’ve been eagerly watching Liam Allan’s open source ILEditor mature into a very convenient tool that I can turn to whenever I have a quick development task to perform and I don’t have an active RDi session open. So I was thrilled to learn about his plans for the next major release!

The beauty of ILEditor is that it starts up quickly, performs quickly, and lets me return to whatever else I was doing. For example, I recently used it to copy and send some CL code to a client while I was on vacation. So fast!

Installing Composer on IBM i

Composer, a tool to manage dependencies in PHP applicationsThe open source Composer tool, which manages PHP project dependencies, has become standard equipment for modern PHP. New to this tool? I recommend this introduction to Composer.

Composer automatically installs or updates required components, known as dependencies, and any others required by those initial components. The required components are defined by the developer in an easy-to-read JSON-formatted text file.

Add apachectl to IBM i for Controlling Apache Web Instances

sobo.redHere at Seiden Group, we seek ways to make IBM i systems more congenial for developers accustomed to other platforms, such as Linux.

Developers coming from a non-IBM i background know how to run the apachectl command to start, restart, and end an Apache web server instance. Instead of apachectl, however, IBM i provides a web-based graphical interface and the commands STRTCPSVR and ENDTCPSVR (be sure to prompt those for parameters using F4).

To supply the “missing” apachectl command for IBM i, I have written a BASH shell script that simulates apachectl on IBM i.
