Input and Output

bake has built in tasks for reading input and writing output in different formats. While this can be useful for general processing, there are some limitations, notably that rich object representations like json and yaml often don't support stream processing.

Input

The input task reads from stdin or a specified --file path. It handles a number of different --format arguments including json and yaml.

> bake input --file data.json --format json output
[{"name"=>"Alice", "age"=>30}, {"name"=>"Bob", "age"=>40}]

Text

Instead of using a file, you can parse a string argument.

> bin/bake input:parse "[1,2,3]" output
[1, 2, 3]

Output

The output task takes the return value from the previous command and outputs it to stdout or the specified --file path. It also handles a number of differnt --format arguments including json, yaml, raw and the default pp.

> bin/bake input --file data.json output --format yaml
---
- name: Alice
  age: 30
- name: Bob
  age: 40
