List of external textual DSLs

See also: External textual DSLs.

This note is a list of all external DSLs (human-editable yet computer-readable textual files) that I know of. For a textual file format to be included in this list, it needs to meet the following requirements:

• A file in this format can be reasonably expected to be edited by a human.
• It needs nothing but a text editor to edit.
• It needs to be difficult to introduce errors.
• It is not based on another file format (this rules out formats based on XML).
