cfg

is a spartan fast configuration language.

It has numbers, strings, lists, and sections.

The reference implementation is WIP. There will most certainly be memory leaks.

You’re not alone: I also wish the code were documented.

Example

cfg has no comments, but let’s pretend we had # comments.

# lists start with a name, then an indent, then a hyphen, a space,
# and then a value
my_list
  - "value"
  - 12

# strings are quoted
my_string "this is a string"

# all numbers are doubles
my_num 42.0

# sections have names, and are indented by 2
my_section
  my_inner_string "inner"
  my_second_numer 23.0

Keys cannot contain spaces. Indents are always two spaces. There is one space between the hyphen and the value in an array, unless there is a linebreak immediately after. This is all.

It is a simple format, some might think it is too simple. It is, however, possible, to write a simple, fast implementation in a few hundred lines of C (QED), and that might be worth a bit of reduction.

See the examples/ directory for an example of how to use the pretty printer and parser APIs.
