xtbb>

A simple XTDB querying CLI.

• Queries can be written at the command line or in your preferred editor.
• Results can be printed in a few formats: tabular, as zipped maps, raw.
• Error contents in EDN are pretty printed.

Usage

Run xtbb! Interactively query XTDB like a repl.

$ xtbb
xtbb - {:url http://localhost:9999/_xtdb/query, :query nil, :editor nil, :dir /tmp/xtbb, :format tabular}

xtbb> {:find [?e ?n] :where [[?e :xt/id][?e :name ?n][?e :active true]] :order-by [[?n :asc]] :limit 5}
"Elapsed time: 21.521875 msecs"

|                          ?e |      ?n |

Editor mode

Write queries with your preferred editor. This is my favorite way to use it.

$ xtbb --editor vim
xtbb - {:url http://localhost:9999/_xtdb/query, :query nil, :editor vim, :dir /tmp/xtbb, :format tabular}

[Enter] to write query in editor, [Ctrl-C] to quit

{:find [?e ?n]
 :where [[?e :xt/id][?e :name ?n][?e :active true]]
 :order-by [[?n :asc]]
 :limit 5}
"Elapsed time: 17.101709 msecs"

Example query file:

;; xtbb - A simple XTDB querying CLI
;; Save a query edn map in this file to run it
;; -----------------------------------------------------------------------------
;;
;; ;; Provide just the query map...
;; {:find [?e]
;;  :where [[?e :xt/id]]
;;  :limit 10}
;;
;; ;; ... Or provide a map with :query, :in-args, :valid-time, :tx-time, :tx-id
;; ;; This format emulates the HTTP API
;; {:query {:find [?e]
;;          :in [?n]
;;          :where [[?e :xt/id] [?e :name ?n]]
;;          :limit 5}
;;  :in-args ["Amelia"]
;;  :valid-time "2023-11-01T21:23:00Z"}

{:find [?e ?n],
 :where
 [[?e :xt/id]
  [?e :name ?n]
  [?e :active true]],
 :order-by [[?n :asc]],
 :limit 5}

Non-interactive mode

Just execute a single query.

$ xtbb --query "{:find [?e], :where [[?e :xt/id]], :limit 10}"

Flags

• --url: XTDB REST API URL. Defaults to the xtdb-in-a-box default URL.
• --query: If a query is provided, just execute that query and exit. This disables default interactive mode.
• --editor: If editor is provided (e.g. "vim"), it will be opened to edit the query as a file.
• --history: If enabled, save a history of queries to a directory. Defaults to "<--dir>/history".
• --dir: Dir to save app data to like the working query and query history. Defaults to "/tmp/xtbb".
• --format: Result print formatting. Options: "tabular", "maps", "raw". Defaults to "tabular".

Installation

The only dependency is Babashka.

1. Install with bbin

bbin install https://raw.githubusercontent.com/elh/xtbb/main/xtbb.clj

xtbb

2. Install manually

# download file or clone repo

./xtbb.clj

Motivation. Why not use the query GUI?

1. CLIs are fun. Why not both?
2. The GUI seems crash on some valid expressions used in the :find.
3. The GUI can be hard to read for verbose errors.

Querying from the clojure REPL is nice too, but I like having an opinionated tool that I can distribute as a CLI.
