  1. Some ramblings on simple CDS modelling with CDL

    A brief note-to-self after digging in to some simple constructs in CDS modelling.

  2. Hands-on domain modelling with CAP's CDS at UKISUG Connect

    A quick overview of the hands-on workshop I'll be running at UKISUG Connect this year.

  3. Quiet cds test output - two ways

    Reducing CAP server log output during tests, in two different ways, via a profile encapsulated set of log level configurations, or via the new cds test command.

  4. 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.

  5. Using @capire modules from GitHub Packages

    Here's how to access and use the @capire namespaced modules that reside in the NPM registry which is part of GitHub Packages.

  6. CDS source formatting and readability

    Embracing a modern approach to source code formatting for human-centric modelling in CAP

  7. Upcoming talks in autumn 2025

    I'm writing this mostly to organise myself and get my preparations in order!

  8. 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.

  9. A reCAP intro to the cds REPL

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

  10. 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.

  11. 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.

  12. 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.

  13. 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.

  14. TASC Notes - Part 9

    These are the notes summarising what was covered in The Art and Science of CAP part 9, one episode in a mini series with Daniel Hutzel to explore the philosophy, the background, the technology history and layers that support and inform the SAP Cloud Application Programming Model.

  17. 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.

  18. 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.
