Overview

Jackson (Java) data format module that supports reading and writing TOML files.

Support exists both at streaming and databinding level.

Note that while both reading (parsing) and writing (generation) are supported, writing will currently (2.13) produce less than optimal formatting -- content is valid and retains information but is typically not "pretty". This may be improved in future.

Status

Jackson 2.12.3 was the first beta release; 2.13.0 the official introduction. 2.13 version is still considered somewhat experimental module.

Maven dependency

To use this extension on Maven-based projects, use following dependency:

<dependency>
  <groupId>com.fasterxml.jackson.dataformat</groupId>
  <artifactId>jackson-dataformat-toml</artifactId>
  <version>2.13.0</version>
</dependency>

Usage

The typical usage is by using TomlMapper in places where you would usually use JsonMapper (and other ObjectMappers) -- but if you want to, it is also possible to use low-level streaming TomlFactory (instead of JsonFactory)

TomlMapper mapper = new TomlMapper();
// and then read/write data as usual
SomeType value = ...;
String doc = mapper.writeValueAsBytes(value);
// or
mapper.writeValue(new File("stuff.properties", value);
SomeType otherValue = mapper.readValue(props, SomeType.class);

For reading and writing, you most commonly use ObjectReader and ObjectWriter, created using mapper object you have; for example:

String props = mapper.writerFor(Pojo.class)
    .writeValueAsString(pojo);
Pojo result = mapper.readerFor(Pojo.class)
    .with(schema) // if customization needed
    .readValue(propsFile);
