* Pre: use debugcli in VSCode.
* Pre: wrap subqueries in parentheses in output SQL.
* Pre: add ExistingColumn.
This lets us make reference to columns by name, rather than only
pointing to qualified aliases.
* Pre: add Into for &str to TypedValue.
* Pre: add Store.transact.
* Pre: cleanup.
* Parse and algebrize simple aggregates. (#312)
* Follow-up: print aggregate columns more neatly in the CLI.
* Useful ValueTypeSet helpers.
* Allow for entity inequalities.
* Add 'differ', which is a ref-specialized not-equals.
* Add 'unpermute', a function for getting unique, distinct pairs from bindings.
* Review comments.
* Add 'the' pseudo-aggregation operator.
This allows for a corresponding value to be returned when a query
includes one 'min' or 'max' aggregate.
* Use fixed-size arrays for bootstrap datoms, not vecs.
* Wide-ranging cleanup.
This commit:
- Deletes some dead code.
- Marks some functions only used by tests as cfg(test).
- Adds pub(crate) to a bunch of functions.
- Cleans up a few other nits.
* Use the cache to make constant queries super fast.
* Fix translate tests to match: we no longer generate SQL for many of them!
* Accumulate additions and removals into the cache.
* Make attribute cache clone-on-write; store it in Metadata.
* Allow caching of fulltext attributes, interning strings.
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.
* Add a prepared query command to CLI.
* Print nanoseconds in the REPL. This is a good problem to have.
* Better CLI timing.
* Use release for 'cargo cli', debug for 'cargo debugcli'.
* Don't enable debug symbols in release builds.
* Clean up CLI code. Fixed order for help.
* Column-align help output.
This puts caching in mentat_db, adds a reverse lookup capability for
unique attributes, and populates bidirectional caches with a single
SQL cursor walk.
Differentiate between begin_read and begin_uncached_read.
Note that we still allow toggling within InProgress, because there might be
transient local state that makes starting a new transaction impossible.
* Add EntityBuilder.add_kw.
This allows you to skip your own attribute lookups, at the cost of
potentially doing the work more than once.
Also does value type checking.
* Add basic coloring of CLI output.
* Add a timer to the CLI.
Toggle it on or off with 'timer on' and 'timer off'.
Output is colorized.
* Add VSCode configuration files.
These allow you to build and run the CLI, build Mentat, or run all tests.
You can use this in conjunction with setting SQLITE3_LIB_DIR to control which SQLite is used.

* Nit: Alphabetical ordering of imports
* Create Cache and provide functions for calling it
* Get tests working. Move to using NamespacedKeyword over KnownEntid in function signature
* Add is_cached check to caching tests
* Move lazy and add/remove boolean flags to enums
* Move function definitions into generic trait and implement trait for AttributeCache
* Remove lazy cache and generalize cache
* Update tests
* Eager cache becomes simple key value store. AttributeMap handles attribute storing specifics
* Update tests to test presence of correct values in cache
* Move EagerCache, AttributeValueProvider and ValueProvider into mentat_db
* Add test for get_for_entid
* Add test for lookup attribute
* Make caches cloneable. Add value_for alongside values_for
* Use cache in attribute lookups
* Split test for values and value and add cardinality
* address review feedback r=rnewman
* Define Store, which is a simple container for a SQLite connection and a Conn.
This is a breaking change.
* Return the FindSpec as part of QueryOutput, not just results.
* Switch to using stderr in appropriate places in CLI.
* Print columns in CLI output.
* Add TypedValue::instant(micros).
* Add From<f64> for TypedValue.
* Add lookup_values_for_attribute to Conn.
* Add q_explain to Queryable.
* Expose an iterator over FindSpec's columns.
* Export edn from mentat crate. Export QueryExecutionResult.
* Implement Display for Variable and Element.
* Introduce a `kw` macro.
This allows you to write:
```rust
kw!(:foo/bar)
```
instead of
```rust
NamespacedKeyword::new("foo", "bar")
```
… and it's more efficient, too.
Add `mentat::open`, eliminate use of `mentat_db` in some places.
Also move `now` into core, implement microsecond truncation.
This is so we don't return a more granular -- and thus subtly different --
timestamp in a `TxReport` than we put into the store.
This includes two other changes:
* Split transact to expose an interface for TermWithTempIds.
* Return TxReport from each InProgress operation, not from commit.
Improve naming of read-only transactions.
Implement entid_for_type.
Simplify get_attribute.
Name ignored var in algebrizer.
Comment attribute_for_ident.
Make KnownEntid a core concept.
Expose lookup_value_for_attribute.
Implement HasSchema and a new query encapsulation on Conn.
Pre: export Queryable.
