IBM Rational Developer (RDi) is good but bloody expensive!

If you are reading this blog then chances are you are (a) an RPG Programmer and (b) using SEU to edit your code and (c) you are frustrated that SEU wont syntax check new RPG anymore! It’s time to leap into an RPG EDITOR or be pushed… RDi is a nice tool but its a bit bloaty and also a very expensive code editor. It cost me $800 a few years back! #YIKES

For freelance programmers like me – the thought of having to pay nearly a thousand dollars just for a source code editor really grinds my gears. But, I still hope that one day, IBM will release a lightweight, desktop Free RPG Editor?

But until that glorious day, this begs the question of “Which RPG Code Editor should a RPG developer use?” or

Updated 2021 – Code Editors come and go and get updated all the time.

This blog from 2015 is old, not as old as SEU but it’s pretty bloody old. So check out the latest blog update with current RPG Code Editors and the best free and commercial IBM i Software IDE’s today

What is the best free alternative to RDi (Rational Developer)?

Free rpg editor

SEU’s syntax checking has been frozen at IBM V6 level and, sadly, this means that good old green screen SEU will not recognize any of the 7.1 RPG enhancements and will flag all these new features as errors.

As far as I know SEU has been stabilized by IBM. This is also known as “declared dead and will be given no future updates”. IBM clearly want people to adopt their flagship code editor for IBM i Software Developers — RDi is Rational Developer for i

RDi is an Eclipse based code editor for IBM i Developers used for writing modern RPG, CL, XML, JAVA, PHP etc code. Ten years back we used it’s predecessor called WDSC “WebSphere Development Studio Client”. If you are not using a code editor then your developers are probably stuck with the twenty year old text based code editor SEU “Stoneage Editing Utility” 😉

There are other code editing tools out there ranging from older opensource and freeware solutions to modern commercial products, but IBM’s RDi is by far the best. IMHO

Free RPG Editors in 2015

What's the best free rpg editor? 1

ORION – The latest FREE offering from IBM. It’s a very simple web based RPG editor. Basic syntax checking but (at time of writing) only accesses source code that is stored in the IFS – which might be a game stopper for you?

ILEditor – ILEditor V1 is an editor for development of ILE applications on IBM i. ILEditor will support development with any ILE language, be it CL, RPG, COBOL, C or C++. Error listing and syntax highlighting is available for all ILE languages. NOTE: ILEditor V2 is no longer free, it’s now a paid COMMERCIAL editor!

Websphere Development Tools – although its free it’s also very old, doesnt support new RPG code and replaced by RDi

RPG Next Gen – I really liked this and used it after WDSC and before moving to RDi. The author has moved to a commercial route, checked out it’s replacement (Mi Workplace)

Paid Alternatives

Mi Workplace – it’s not free but it’s cheap! Consider that Rdi is close to $900 and MiWorkplace is close to $40 – but it’s a full featured editor and priced correctly. If you cant get RDi this is your best best
