quai

Interactive Quarb — a session REPL where every line becomes a reusable query.

pip install quai
quai data.json

quai opens a session over one or more sources and holds it. Each line you run is labelled &1, &2, … — and every label is a reusable macro: not the printed value, but the query that produced it, ready to continue through the pipe. It is the notebook loop, cell by cell, except a cell is a path into your data.

&1  /teams/*/members/*
    /teams/0/members/0  ⋮  (every member, across all teams, one path)
&2  &1 | [/langs/*:: = 'Go'] | /name::
    ada
    eu
&3  &1 @| count
    6
  • &N re-runs line N; continue with a pipe (&N | /key::, &N | [pred], &N @| count).
  • &N# replays line N's output frozen, as it was when it ran.
  • def &x: … ; adds a named fragment; :history, :reset, :help, :quit are the commands.

The engine rides in on the quarb dependency, so quai reaches every local source quarb does — JSON, YAML, TOML, CSV, XML, HTML, Markdown, SQLite, kaiv, the filesystem, git, archives, XLSX, and source code — and several at once mount under one root for cross-source <=> joins.

Try it in the browser at demo.quarb.org/quai (no install), and read the graph cookbook for the recipes.
