cfgcmp

1 3 6.1 JavaScript

Compare configuration files.

Project mention: Show HN: A diff tool for ini config files | news.ycombinator.com | 2024-03-26

I've been handling lots of configuration files at work lately and I needed to compare some of them but diff kinda sucks for this use case.
I whipped up something real quick and it helped quite nicely.
I might need to compare some configuration in JSON next so I'll probably add support for it.

ADO-History-Diff

1 0 8.9 JavaScript

Azure DevOps extension to show the history of work item fields and comments with proper diffs.

Project mention: Show HN: Azure DevOps History Diff | news.ycombinator.com | 2024-04-21

The standard history tab of work items in Azure DevOps shows only the old and new values of each field, without highlighting the actual changes within it. This makes spotting the difference very hard for fields that usually contain a lot of text; most prominently, the standard "Description" and "Repro Steps" fields and the comments. This extension adds a new tab to work items that shows the full history of every field, while computing an appropriate diff for each one.
