You can now specify `$` as the position to apply an edit, signifying the
end of the file. (That prevents you from having to calculate the size
of the file yourself.)
This patch updates the CLI to use anyhow and thiserror for error
management. The main feature that our custom `Error` type was providing
was a _list_ of messages, which would allow us to annotate "lower-level"
errors with more contextual information. This is exactly what's
provided by anyhow's `Context` trait.
(This is setup work for a future PR that will pull the `config` and
`loader` modules out into separate crates; by using `anyhow` we wouldn't
have to deal with a circular dependency between with the new crates.)
* Requery parse table after breaking down parse stack due to invalid lookahead
* Include Ruby parser in randomized test suite
Ruby and PHP are our only two languages that use non-terminal extras.
Adding Ruby uncovered some bugs.
* Print edited source code when running parse --edit w/ debug flag
* Recompute lookahead when breaking down stack on invalid lookahead
* Fix stack summary leak when there are two discontinuities on a stack version
* Rename parse_str to parse and make it polymorphic.
* Rename parse_utf8 to parse_with, since it is now the callback-based
version of parse
* Add a parse_utf16 method analogous to parse
* Rename existing parse_utf16 method to parse_utf16_with
This brings in the changes from tree-sitter/rust-tree-sitter#5
