Eq

A simple CLI tool for processing EDN data.

Basic usage

$ eq --help

Process EDN data (https://github.com/edn-format/edn) from stdin and
write it to stdout.

Usage: eq [OPTIONS]

  -h, --help             Display this message.
  -c, --compact          Compact output, don't pretty print.
  -r, --readable         Print readable EDN data.
  -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.

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}}
