How to enable JSON or YAML validation with JSON Schemas in IntelliJ

Sat, 03 Jan 2026 00:00:00 +0000

This is another article about plugin development for IntelliJ-based IDEs. In this article, I am describing how to implement some support for JSON or YAML files using a JSON Schema. While the JSON support is expected, the YAML support is a bit more surprising. It is possible because JSON and YAML are very similar formats, YAML 1.2 even being a superset of JSON.

I recently implemented that trick in my plugin FHIR® and SUSHI Support to provide a better experience while working with a specific YAML file (the sushi-config.yaml file). I discovered that neat feature in the YAML documentation, but I had to use the IntelliJ Platform Explorer to discover how a plugin could register a new JSON Schema in the IDE. That topic isn't covered by the IntelliJ Platform SDK Documentation documentation, so I am sharing my findings here.

How I migrated my emails from Infomaniak to Fastmail

Sun, 28 Dec 2025 00:00:00 +0000

The reason for migrating is that I’ve been a bit disappointed by Infomaniak’s email service lately. While parts of the service have improved, like the Android app that used to have really frequent updates, which would log you out of your account on each update at the time. But the webmail interface is still quite clunky, with some unnecessary nagging to set it as the default mailbox in the browser (I haven’t seen such nagging in Gmail, for example).

Beginner's guide to Apache Camel and IPF for the Swiss EPR

Sun, 29 Sep 2024 00:00:00 +0000

Introduction#

In this article, I will focus on using these libraries with the Spring Boot integration. While it is not mandatory to use Spring Boot, it is a good choice, as it makes configuring the application much easier. IPF provides starters dependencies that will automatically configure the Camel context and the IPF components for you. I will present the manual configuration of the Camel context and the IPF components, as it is useful to understand how everything works.

How to implement highlighted inline code blocks in Hugo

Thu, 05 Sep 2024 00:00:00 +0000

I have written multiple documentation websites using Material for MkDocs, and got used to the highlighted inline code blocks. It allows adding code snippets inlined with the text, while keeping the syntax highlighted (for known languages). The syntax chosen by the plugin that introduced this feature, InlineHilite, uses a shebang to specify the language: #!python print(“Hello, World!”) (surrounded with backticks) would be rendered as #!python print("Hello, World!").

Implement syntax highlighting of a new language in JetBrains IDEs

Mon, 18 Mar 2024 00:00:00 +0000

I regularly spend time working on FHIR ImplementationGuides, and I use the Visual Studio Code IDE to develop them. It is an IDE I used to work with, but as of lately, my preference goes to the Jetbrains IDEs.

The FHIR ImplementationGuides are written in a mix of Markdown, HTML, XML, JSON, INI and a specific language called FHIR Shorthand (FSH). While the former languages are properly supported in many IDEs, the latest is only supported in Visual Studio Code through a dedicated extension.

Improving performance of the IG Publisher: I/O operations

Thu, 11 Jan 2024 00:00:00 +0000

The IG Publisher is the reference tool to build FHIR implementation guides. It is a Java application built upon the FHIR Core library, that reads the implementation guide sources and generates a FHIR package and a web documentation. It is a quite complex application, and new versions are released quite regularly.

I recently had to build a large implementation guide, and it took the IG Publisher around 3 hours to complete. The memory usage was quite high (around 20 GiB at peak) and the result was a 2.57 GiB directory. While waiting for the completion, I was wondering if there was a way to reduce the completion time.
