I need a simple heap visualization for debugging purposes. I'm using GHC 8.0.2 to compile a large and complex yesod-based web app. What's the quickest and easiest way? Vacuum looks simple and nice. But it has some long-outstanding PRs against it to support GHC 7.10 and GHC 8.0 that were never applied. https://github.com/thoughtpolice/vacuum/issues/9 Getting ghc-vis to compile looks hopeless, for a number of reasons. The dependencies on gtk and cairo are huge. It hasn't been updated on Hackage for a year and a half. It requires base < 4.9. I need to run the visualizer either on a headless Ubuntu 16.04 server, or locally on Windows. And anyway, the fancy GUI in ghc-vis is way overkill for me. The heap scraper backend for ghc-vis, ghc-heap-view, looks usable, and better supported than vacuum. But is there a quick and simple visualizer for its output, without ghc-vis? Is there anything else? Is the best option to fork vacuum and and try to apply the PRs?
