germinate

This crate provides a method of injecting variables from multiple external sources into a template string. Sources can be anything as long as they implement the Loader trait which handles the loading of the variables in a standard way.

Features

• default - ["aws"]
• aws - Enable the AWS value sources

Sources

Built In

These are the currently implemented sources and their associated template keys

Example

let mut seed = Seed::new("Hi %env:NAME%!");
let output = seed.germinate().await?;

assert_eq!("Hi John!", output);

Custom Sources

You can also include your own sources using the Seed::add_custom_loader method. The only requirement is that the custom loader must implement the Loader trait

Example

let mut seed = Seed::new("Hi %name:name%");

// Add a custom loader for the name key. This is the loader that will be used whenever
// germinate finds %name:...% in the template string
seed.add_custom_loader("name".to_string(), Box::new(NameLoader {}));

let output = seed.germinate().await?;

assert_eq!("Hi John", output);

Binary

Germinate provides a CLI for templating files, available from the Github releases. To run the CLI, cimply download the binary for your system and check the usage with germinate --help

Example

The CLI can be used to parse an template file and output it either to stdout or optionally, an output file

# To print the parsed result to stdout
germinate myfile.txt.tmpl

# To write the output to a file
germinate myfile.txt.tmpl -o myfile.txt
