Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Frawk: An efficient Awk-like programming language. (2021)
gron (https://github.com/tomnomnom/gron) to transform it and query and then invert the transformation?
- Show HN: Flatito, grep for YAML and JSON files
- Gron: Make JSON greppable
-
Make JSON Greppable
It buffers all of its output statements in memory before writing to stdout:
https://github.com/tomnomnom/gron/blob/master/main.go#L204
- Ask HN: What are some unpopular technologies you wish people knew more about?

Jaq – A jq clone focused on correctness, speed, and simplicity
Have you tried `gron`?
It converts your nested json into a line by line format which plays better with tools like `grep`
From the project's README:
▶ gron "https://api.github.com/repos/tomnomnom/gron/commits?per_page..." | fgrep "commit.author"
json[0].commit.author = {};
json[0].commit.author.date = "2016-07-02T10:51:21Z";
json[0].commit.author.email = "[email protected]";
json[0].commit.author.name = "Tom Hudson";
https://github.com/tomnomnom/gron
It was suggested to me in HN comments on an article I wrote about `jq`, and I have found myself using it a lot in my day to day workflow

Interactive Examples for Learning Jq
> So all I want is a tool to go from json => line oriented and I will do the rest with the vast library of experience I already have at transformations on the command line.*
The tool for that is likely https://github.com/tomnomnom/gron

Modern Linux Tools vs. Unix Classics: Which Would I Choose?
If JQ is too much, see GRON &| Miller
gron transforms JSON into discrete assignments to make it easier to grep for what you want https://github.com/tomnomnom/gron
Miller is like awk, sed, cut, join, and sort for data formats such as CSV, TSV, JSON, JSON https://github.com/johnkerl/miller
- XML is better than YAML
-
jq 1.7 Released
And jless [1] and gron [2].
This is the first I'm hearing of gron, but adding here for completeness sake. Meanwhile, JSON seems to be becoming a standard for CLI tools. Ideal scenario would be if every CLI tool has a --json flag or something similar, so that jc is not needed anymore.

JsonPath
-
Refactoring Toward Configurability
For this example, we will use JSON files to encode the application's behavior and query it using JSONPath.
- Ask HN: What is something you built but never marketed?
-
Running Jenkins on PR in Azure DevOps
As shown above in order to access the root element of a JSON payload we can create variable (data) and assign the $ (using Json Path convention) in the expression tab.
-
what's the best way to search all child objects in java?
You certainly could implement a recursive traversal, as /u/raevnos suggested, but it might be easier to use something like JsonPath to do it for you.
-
Query with jsonpath
If you work with REST interfaces for any amount of time, you'll run into "json path". You can extract and manipulate the json received with an API call.
-
How would experienced devs handle checking JSON objects for specific property condition?
Look into JSONPath and its one Java implementation.
-
Like JQ, but for HTML
is anyone else using the https://github.com/json-path/JsonPath over the jq route?
I hope we standardize on some jq query language, like we have with a base set of SQL syntax
-
Which JSON parsers do not require me to duplicate the document model?
I use JsonPath for this. This fits my use case of picking apart JSON responses from APIs in Cucumber tests, which is based on textual descriptions and I'm not using Java classes for the mapping.
-
Serverless Complex Event Processing with Apache Flink
flatMap — A Map function (can be of Rich type if need be) that extracts data from the input event which is a stringified JSON object. Of the three flapMaps, two of them extract & parse the relevant data into a defined model (the data modelling is based on POJO — plain old java object classes.) using JsonPath, the third flapMap is a RichCoFlatMapFunction that determines after correlating events from the two sources whether it should be forwarded to the sink or not.
-
Traversing nested data-structures in various languages
JSONPath confers pretty much the same concept onto JSON too with much the same syntax. There are JPath implementations for most languages now.
