Congratulations to releasing. :)

For the record, I think using a D parser in dfmt is a dead end. Surely,
for certain cases the additional information is necessary. However, it
restricts dfmt to only format syntactically valid snippets. This means
you cannot (in general) format parts of a file, e.g. within a diff or

Example where parsing helps: "foo : bar" or "foo: bar" depending on the
context. The former within import statements, the latter within switch

Example for a snippet you cannot parse: The body of a switch statement
without the switch. The 'case' keyword would be an error.

It depends on how the parser is implemented. For example, the Eclipse Java parser is very flexible when it comes to this. You can choose to either parse a complete file or just a fragment of code.

Effectively, you want to parse, but not with a normal parser. Great
formatting seems to require a special (more flexible, less correct)
parser. This is what clang-format does.

clang-format uses the lexer with the help of the parser. It only changes whitespace. At least according to the talk I watched, which is a couple of years old.
