# eql-cli

A command line script for executing [EQL](https://github.com/edn-query-language/eql)

queries on [EDN](https://github.com/edn-format/edn) data.

Powered by [pyramid](https://github.com/lilactown/pyramid) and [babashka](https://github.com/babashka/babashka).

## Install

### Homebrew

```bash

brew install lilactown/brew/eql

```

### Scoop

See https://github.com/littleli/scoop-clojure#tools

### Manual

* Install [babashka](https://github.com/babashka/babashka)

* Download the [eql](./eql) script and place it on your `PATH`.

## Usage

```bash

eql --query '[:foo]' '{:foo 123 :bar 456}'

```

Returns `{:foo 123}` as the result.

Data is also accepted over STDIN, so you can do the following

```bash

echo '{:foo 123 :bar 456}' | eql --query '[:foo]'

```

## Usecases

EQL over arbitrary data can be useful as a "`select-keys` on steroids" for deep

nested data.

```bash

curl -s https://pokeapi.co/api/v2/pokemon/ditto | # fetch some data

jet --from json --to edn --keywordize | # convert it from JSON to EDN

eql --query "[:id :name :height :weight \

             {:abilities [{:ability [:name]}]}]" | # select just the keys we want

jet # pretty print

```

Outputs

```clojure

{:abilities [{:ability {:name "limber"}} {:ability {:name "imposter"}}],

 :height 3,

 :id 132,

 :name "ditto",

 :weight 40}

```
