kras - Detect, highlight and pretty print structured data

This tool can find structured data of any kind inside of plain string, parse it and pretty-print it:

It can detect and parse almost any kind of data:

  • json
  • python
  • rust

and probably many more. Don't hesitate to open an issue if your data wasn't processed correctly

Installation

cargo install kras-rs

Usage

Usage: kras [OPTIONS] [INPUT]...

Arguments:
  [INPUT]...  Input files or stdin

Options:
  -i, --indent <INDENT>  identation. 0 to disable (colorization is still performed) [default: 2]
  -c, --color <COLOR>    colorize output [default: auto] [possible values: auto, yes, no]
  -C, --force-color      alias for --color yes
  -s, --sort             sort keys
  -r, --recursive        try to parse nested strings
  -j, --jobs <JOBS>      number of parallel jobs. Default is num_cpus
  -w, --width <WIDTH>    maximum width of output [default: 80]
  -m, --multiline        look for data spannding several lines. This will read wholle input to memory
      --robust           use more robust, but slower method to detect structured data
      --debug            debut mode
  -h, --help             Print help
  -V, --version          Print version

Using with pgcli

kras really shines when used for reading jsons stored in database. For pgcli add to your .config/pgcli/config

pager = kras -Csw120 | less -iRXF

Now your jsons will be pretty-printed! Hint: use \x

Acknowledgement

This tool is powered by these amazing libs: pom for parsing and pretty for pretty-printing

Trivia

The name kras comes from russian root крас- - a beginning of words such as красивый (pretty), красный (red) and красить (to paint). That's what this app does: makes data pretty and paints it red (but not only red)
