Modelling contained-in relationships with compositions in CDS
A short study of the features of CDS for modelling classic contained-in relationships, with a focus on the details, and a lean towards anonymous aspects.

Neovim configuration for file and module navigation in CDS models
In this post I describe how I extended my Lua-based Neovim configuration for CDS filetypes to improve navigation to referenced files and modules.

A reCAP intro to the cds REPL
Here's a summary of my talk on the cds REPL at this year's reCAP event.

A modern and clean Neovim setup for CAP Node.js - configuration and diagnostics
In this post I describe my re-worked basic setup for working with CAP Node.js in Neovim, focusing on the configuration and digging into the LSP based diagnostic facilities.

Point free coding and function composition
In this post I explore and show examples of the concepts of point free coding, of chains of functions through which data flows, and of function composition.

FP, function chains and CAP model loading
Understanding functional programming approaches, no matter how trivial, can help in other areas. Here I explain how being comfortable with function chains helped in working out why a required (but unused) service was being loaded into the overall CDS model in a CAP project.

Level up your CAP skills by learning how to use the cds REPL
These are notes I wrote for my talk at SAP Inside Track Madrid on 20 March 2025. I wrote them partly to think about what I wanted to say, and partly to share the info in written form too. Note that the idea is to introduce the concepts and show some basic examples for cds REPL "initiates". Nothing too exotic.

CAP Node.js plugins - part 3 - writing our own
This blog post accompanies part 3 of a three part series where we explore the CDS Plugin mechanism in CAP Node.js to find out how it works. In part 1 we looked at the plugin mechanism itself and how it worked. In part 2 we used the cds REPL to start our CAP service running and to introspect it. In this part we'll use what we learned and discovered in the first two parts to write our own plugin.

CAP Node.js plugins - part 2 - using the REPL
This blog post accompanies part 2 of a three part video series where we explore the CDS Plugin mechanism in CAP Node.js to find out how it works. In part 1 we looked at the plugin mechanism itself and how it worked. In this part we use the cds REPL to start our CAP service running and to explore it - to introspect it.
