Taken from this amazing answer and condensed to a one-line grep:

grep -Po '(?(DEFINE)(?<ws>[\t\n\r ]*)(?<number>-?(?:0|[1-9]\d*)(?:\.\d+)?(?:[Ee][+-]?\d++)?)(?<boolean>true|false|null)(?<string>"(?:[^\\"\x00-\x1f]|\\["\\bfnrt\/]|\\u[0-9A-Fa-f]{4})*")(?<pair>(?&ws)(?&string)(?&ws):(?&value))(?<array>\[(?:(?&value)(?:,(?&value))*)?(?&ws)\])(?<object>\{(?:(?&pair)(?:,(?&pair))*)?(?&ws)\})(?<value>(?&ws)(?:(?&number)|(?&boolean)|(?&string)|(?&array)|(?&object))(?&ws)))(?&object)'

Useful for grepping mixed logs, extrating JSON and then processing it with jq

let's say you have a C++ project in Nix that you want to work on with CLion so that the nix dependencies are available.

1. create a .nix utility directory in your project directory.
2. put the below nix-run.sh and nix-cmake.sh in the .nix directory.
3. in the .nix directory create symlinks for make, gcc, g++ - and maybe more tools, that need to have the nix dependencies and build tools available - and point them to nix-run.sh
4. then, in Settings -> Build, Execution, Deployment -> Toolchains set CMake to the path to nix-cmake.sh and point all other build tools to the symlinks you've created.
