JSON operator allows to compare the JSON representation of data against expectedJSON . expectedJSON can be a: expectedJSON JSON value can contain placeholders. The params are for any placeholder parameters in expectedJSON . params can contain TestDeep operators as well as raw values. A placeholder can be numeric like $2 or named like $name and always references an item in params . params can also contains [encoding/json/v2.Options] when [encoding/json/v2] must be used, see jsonv2 example. Numeric placeholders reference the n’th “operators” item (starting at 1). Named placeholders are used with Tag operator as follows: It makes no difference whatever the underlying type of…from go-testdeep.zetta.rocks

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT▲688

  I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
