## Supported helpers

### `from`

Searches for the prefix and starts with it if it is found. Otherwise, the entire string is returned.

    {{ from "begin" "prefix begin text end" }}

renders to:

    begin text end

### `to`

Searches for the prefix and starts with it if it is found. Otherwise, the entire string is returned.

    {{ to ")" "hello)" }}

renders to:

    hello

### `render`

Processes an argument as `handlebars`'s template.

    {{ render "some handlebars template" }}

renders to:

    some handlebars template

This does not look useful until we use it in conjuction with other helper such as `read_to_str` from [handlebars_misc_helpers](https://crates.io/crates/handlebars_misc_helpers):

    {{ render ( read_to_str "templates/README.md" ) }}

### `codeblock`

Allows to insert markdown's fenced code block. Content would be trimmed.

    {{ codeblock "bash" "echo test" }}

renders to:

    ```bash
    echo test
    ```

### `exec`

Allows to include output of command.

    {{ exec "echo test" }}

renders to:

    test

### `handlebars_misc_helpers`

All helpers from [handlebars_misc_helpers](https://crates.io/crates/handlebars_misc_helpers).
