pipeLion

Pipelion is a simple, extensible, one-line expression language to pipe data through processing and transform functions. Pipelion stems from the guts of timelion and kable extending their caged potential to other projects and use-cases.

• status: experimental, unstable

pipeLion Expressions

Pipelion functions are chained to each other, just like streams.

Data Input

Pipelion accepts 'strings',json objects, arrays of json objects

Strings will be modified into an object inside an array with key "data":"string" Objects will be modified into array with an object inside

[{"cpu_percent": 100, "time":123}, {"cpu_percent": 80, "time":124}, {"cpu_percent":30, "time":125}]

Pipelion

.average(cpu_percent=true)

Data Output

[
  { cpu_percent: 100, time: 123, cpu_percent_average: 70 },
  { cpu_percent: 80, time: 124, cpu_percent_average: 70 },
  { cpu_percent: 30, time: 125, cpu_percent_average: 70 }
]

Installation

npm install -g pipelion

Usage

pipelion {expression} {input}

Examples

Pipelion has a few small examples

Consuming a string

pipelion ".file(string.json)"

Consuming objects

pipelion ".file(loki.json).parseLoki().flatten()"

pipelion ".fetch('https://api.crossref.org/works?query.author=terry_pratchett').flatten()"

pipelion ".fetch(https://jsonplaceholder.typicode.com/posts).filter(userId=10)"
