What is TOML?

TOML is the new file format to configure Flyway using configuration files, replacing the old .conf format.

How to use TOML

Structure of TOML files

  • Every key/value pair should be on a new line, unless they are in an inline table.
  • There is no need for semicolons or any other character to end a line.
  • There should be spaces around every key pair and the equals sign.
  • TOML is case-sensitive, so keys must be written exactly as they are in the documentation.

Strings

Strings are defined by the key followed by the value in double quotes.

string1 = "Hello World" 

Integers

Integers are defined by the key followed by the number.

integer1 = 42 

Booleans

Booleans are defined by the key followed by true or false.

bool1 = true
bool2 = false 

Arrays

Arrays are defined by the key followed by values in square brackets.

A terminating comma is allowed inside the array.

array1 = ["value1", "value2", "value3",] 

Maps

Maps are enclosed in curly brackets and include the key being equal to the value.

Terminating commas are not allowed at the end of maps.

map1 = { key1 = "value1", key2 = "value2" }

Tables

Tables are the collection of key/value pairs. They have their title in square brackets followed by a list of the key pairs.

Different tables can have the same keys.

[table1]
key1 = "value1"
key2 = 5

[table2]
key1 = "value2"
key3 = true

Inline Tables

Inline tables are similar to tables but are contained inside curly braces on a single line. They use a comma between elements, and do not allow terminating commas.

The formatting of the key/value pairs is the same as for tables.

table1 = { key1 = "value1", key2 = "value2" }

Tables can also be inlined inside other tables.

table1 = { table2 = { key1 = "value1" }, table3 = { key1 = "value2" } }
