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

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)
