Eq

A simple CLI tool for processing EDN data.

Basic usage

$ eq -h

Usage: eq [OPTIONS]

  -c, --compact              Compact output, don't pretty-print
  -d, --dissoc K         []  Apply #(dissoc % K) to each parsed edn object.
      --apply-dissoc KS  []  Apply #(apply dissoc % KS) to each parsed edn object.
  -g, --get K            []  Apply #(get % K) to each parsed edn object.
      --get-in KS        []  Apply #(get-in % KS) to each parsed edn object.
  -s, --select-keys KS   []  Apply #(select-keys % KS) to each parsed edn object.
  -v, --version              Prints the eq version
  -h, --help

Multiple --dissoc, --apply-dissoc, --get, --get-in, --select-keys options may be passed,
in which case the output of each will be on a separate line.

Pretty printing

$ echo '{:id 1 :name "foo" :geo {:country "US" :region "CA"} :date "2000-01-01T00:00:00Z"}' | eq

{:date "2000-01-01T00:00:00Z",
 :name "foo",
 :geo {:region "CA", :country "US"},
 :id 1}

Field extraction

$ echo '{:id 1 :name "foo" :geo {:country "US"}}{:id 2 :name "bar" :geo {:country "FR"}}' \
  | eq --get :id --get-in '[:geo :country]' | xargs -n2

1 US
2 FR

Map manipulation

$ echo '{:id 1 :name "foo" :geo {:country "US"}}{:id 2 :name "bar" :geo {:country "FR"}}' \
  | eq --dissoc :geo

{:name "foo", :id 1}
{:name "bar", :id 2}

$ echo '{:id 1 :name "foo" :geo {:country "US"}}{:id 2 :name "bar" :geo {:country "FR"}}' \
  | eq --apply-dissoc '[:name :geo]'

{:id 1}
{:id 2}

$ echo '{:id 1 :name "foo" :geo {:country "US"}}{:id 2 :name "bar" :geo {:country "FR"}}' \
  | eq --select-keys '[:id :geo]'

{:id 1, :geo {:country "US"}}
{:id 2, :geo {:country "FR"}}

Install

npm install -g edn-eq

Requirements

eq is written in ClojureScript targeting node.js. Therefore it requires a reasonably recent version of node.js (>=0.10) and expects the node executable to be on your PATH.

On Ubuntu, the node.js binary is nodejs instead of node. Installing the nodejs-legacy package will add the appropriate symlink.
