This is kinda rough right now, since it involves actually pulling in the old kdl v1. Not ideal, but workable as a stepping stone while a real v1 parser gets written.
Fixes: https://github.com/kdl-org/kdl-rs/issues/32
This implements a proposed draft of a KQL engine,
allowing CSS selector-style querying of KDL documents (and nodes)
in a variety of different ways.
This necessitates passing the input around through all the sub-parsers so they
can compute their own sub-spans, which in turn necessitates making most of the
subparsers into nom-style 'function builders' by wrapping them in closures and
returning the closures.
The current impl hides this functionality behind an on-by-default "span" feature.
Some fallout of this change:
There is now a private parser::KdlParser type that must be constructed with the
full input for all span computation. The parser::parser method has been moved to
a method of this to make sure the full_input used for span computation is the
same one passed to parsing. In doing this a bug where the span of errors would
be incorrectly computed for non-ascii strings has been fixed.
Types now manually implement PartialEq and Hash to avoid incorporating the span
of the item into those computations.
All parser combinators must first have the KdlParser applied before using them,
making their signatures far more complex. Unfortunately KdlParser::parse can't
apply that for you because I don't think it's possible to express that complex
of a signature and not have the lifetimes get messed up.
Fixes#46
When comparing two different `KdlNode` or `KdlDocument`, it's useful to
have a "canonical" representation where formatting differences do not
matter.
`clear_fmt` removes all formatting from a `KdlNode`, but does not apply
recursively, as a result, it doesn't create a canonical representation.
`clear_fmt_recursive` solves this by applying `clear_fmt` recursively to
the contents of the node.
While the type of entries was parsed, there was no way for the library
user to access it. This commit let the user access the `ty` field of the
`KdlEntry` struct. It mirrors the accessors on the `value` field.
This commit includes a whole bunch of fixes, some of which are significant changes to the parser and some related functionality. But I consider all changes to be bugfixes because they were compliance failures.
This new version of kdl-rs is a complete rewrite that introduces
a formatting-aware-and-preserving parser, much like toml_edit et al.
BREAKING CHANGE: Completely new API and bumped MSRV to 1.56.0.
