3dc68bcd38 Combine NamespacedKeyword and Keyword. (#689) r=nalexander
* Make properties on NamespacedKeyword/NamespacedSymbol private

* Use only a single String for NamespacedKeyword/NamespacedSymbol

* Review comments.

* Remove unsafe code in namespaced_name.

Benchmarking shows approximately zero change.

* Allow the types of ns and name to differ when constructing a NamespacedName.

* Make symbol namespaces optional.

* Normalize names of keyword/symbol constructors.

This will make the subsequent refactor much less painful.

* Use expect not unwrap.

* Merge Keyword and NamespacedKeyword.

c8f74fa41b [edn] Round-trip instants. (#686) (#687) r=rnewman
First, the parser had a small grouping bug where-by it wouldn't parse
Z as timezone correctly.  Second, we weren't printing instants in the format
that we parse.

Speed up EDN parser (fixes #445) (#581) r=nalexander
Fixes from @kevinmehall.

* Prefer character sets over backtracking in the EDN parser.
* Avoid duplicate effort when parsing floats in the EDN parser.
* Clean up duplicate position tracking code.

This turns out to have little performance impact, but makes the grammar
much cleaner.

* Fix EDN work to pass tests with correct numeric precedence.

85f3b79f75 Support a limited set of '.'-prefixed non-keyword symbols. (#352) r=nalexander
This commit allows `.` and `...` to parse correctly as `PlainSymbol`.

Tests in edn, query-translator, and the top level have been added.

81af295948 Start installing SQL schema. (#171) r=rnewman
* Start installing the SQLite store and bootstrapping the datom store.

* Review comment: Decomplect V2_IDENTS.

* Review comment: Decomplect V2_PARTS.

* Review comment: Pre: Expose Clojure's merge on Value instances.

* Review comment: Decomplect V2_SYMBOLIC_SCHEMA.

* Review comment: Decomplect V1_STATEMENTS.

* Review comment: Prefer ? to try!.

* Review comment: Fix typos; format; add TODOs.

* Review comment: Assert that Mentat `Schema` is valid upon creation.

* Review comment: Improve conversion to and from SQL values.

This patch factors the fundamental SQL conversion maps
between (rusqlite::Value, value_type_tag) and (edn::Value, ValueType)
through a new Mentat TypedValue.  (A future patch might rename this
fundamental type mentat::Value.)

To make certain conversion functions infallible, I removed
placeholders for :db.type/{instant,uuid,uri}.  (We could panic
instead, but there's no need to do that right now.)

* Review comment: Always uses bundled SQLite in rusqlite.

This avoids (runtime) failures in Travis CI due to old SQLite
versions.  See 432966ac77.

* Review comment: Move semantics in `from_sql_value_pair`.

* Review comment: DB_EXCISE_BEFORE_T instead of ...BEFORET (no underscore).

* Review comment: Move overview notes to the Wiki.

c4735119c4 Implement a basic EDN parser. (#149) r=rnewman,bgrins,nalexander
The parser mostly works and has a decent test suite. It parses all the
queries issued by the Tofino UAS, with some caveats. Known flaws:

* No support for tagged elements, comments, discarded elements or "'".
* Incomplete support for escaped characters in strings and the range of
  characters that are allowed in keywords and symbols.
* Possible whitespace handling problems.
