Object builder

Build objects from your console! This tool allows you to create JSON, YAML, TOML (and potentially more) formatted strings from console.

Installation

From crates.io

cargo install object-builder

From source

git clone https://gitlab.com/Yannik_Sc/object-builder.git
cd object-builder
cargo install --path .

Example

Basics

After its installation the Object Builder can be called using the ob command.

ob test=true
# Results in:
# {"test": true}

# The same is possible with yaml
ob test=true -o yaml
# test: true

# or toml
ob test=true -o toml
# test = true

Currently Yaml, Toml and Json are supported as output format. Json is used as default though. In future there might be more formats. For the most up-to-date list of formats check ob --help.

Nested calls

To make more complex structures you can use the output of ob as an input for it using command substitution.

ob value="$(ob -a some array)"
# {"value":["some","array"]}

The same, of cause, can be done with toml and yaml as output format. This however should only be set on the most outer ob call otherwise the input value may result in an error.

Array implication

ob generates an array when you pass the -a flag. This however can be implied as well when none of the inputs contain an equal sign =.

ob value1 value2 value3
# ["value1","value2","value3"]

ob value1 value2= value3
# {"value1":null,"value2":"","value3":null}

Passing an = without value will result in an empty string for the given key. All keys that don't even contain the sign will be assumed null.

Converting with stdin

Since 1.1.0 the object builder can get yaml and json strings piped in to the stdin. Those files can be outputted/ effectively converted by this using a different -o output type.

# Input: {"test" true}
cat my.json | ob -o yaml
# Output: test: true
