This commit adds an RPC service to the dicebot, allowing external
applications to control it. The project was converted to a cargo
workspace to house the protobuf definitions in a common crate
(tenebrous-rpc), so that clients and servers can make use of these
protobuf definitions.
Adds fuzzy room search that can also set by exact ID, and refactors
the code to get room list for user into a common function and struct
for use by both commands.

- Fix constraint violations when recording users in rooms (migration fix).
- Switched to tracing_subscriber to get log events from matrix SDK.
- Remove "Applying migration" messages, and rely on refinery to log instead.
- Log when an outgoing error is encountered.

- Adds migrations for the necessary tables.
- Implements the user variables database functions.
- Adds sqlx metadata for 'offline' use so we can build without a database.

Instead of relying on all parts of the application to construct both
HTML and plain-text responses, we now construct only HTML responses,
and convert the HTML to plain text right before sending the message to
Matrix.
This is a first iteration, because the plain text has a few extra
newlines than it should, created by use of nested <p> tags.

This upgrade introduces a handful of breaking changes in the Rust
Matrix SDK.
- Some types have disappeared and changed name.
- Some functions are no longer async.
- Room display name now has a Result type instead of just returning
the value.
- Client state store has breaking changes (not really a big deal).
This required introduction of a new type to store room information
that we are interested in on the context struct. This new RoomContext
is required mostly due to unit tests, because it is no longer possible
to instantiate the Room type in the Matrix SDK.
By using rev instead of branch, we were somehow stuck on a very old
version of the SDK. The dependency has now been switched to branch
instead of rev, and the SDK updates properly to latest master when
carg update is called.
The database API for user variables has changed somewhat again, this
time closer to the proper vision. There are now two separate sled
Trees in the Variables struct, one for user-defined variables, and one
for counts. Keys have been changed to be username-first, then room ID.
The signatures of the functions now also use a strongly-typed struct,
UserAndRoom.
As part of this, the Context object now once again avoids allocating
new strings.
Other random changes included here:
- Remove tempfile crate in favor of sled temporary db config.
- Add bincode crate in anticipation of future (de)serializing.
This is a bit of a large commit that adds basic database migration
support. It also alters the way user variables are stored in a way
requiring manual migration of existing data. The first automated
migration adds variable count in a new place.
This commit introduces the Sled embedded key-value store for keeping
track of user variables on a per-room basis. Extensive changes were
made to the command module to separate concerns and also pass the
database "connection" down the line.
- A new "Context" object was created to hold information and state
needed for command execution (namely the database).
- Database is very simple for now, storing only user variables.
Refactoring later for storing more complicated types.
- State actor moved into Actors struct, in preparation for either
more actors, or ripping the whole thing out entirely.
- Other modules are also more properly separated, notably
the config module is entirely self-contained.
This commit refactors the parsing and rolling for the dice pool system
to prepare for support of user variables. The nom parser was dropped
in favor of the easier-to-understand combine parser in most parts of
the code.
A breaking change was introduced into the dice pool syntax to allow
for proper expressions and variables. The syntax is now
"modifiers:pool-amount", e.g. "n:gnosis+8". The simple single-number
syntax with no modifiers is also still understood.
Dice pool expressions are translated into a Vec of "Amount" objects,
stored by the DicePool struct. They have an operator (+ or -) and
either a number or variable name. When the dice pool is rolled, this
list of Amonuts are is collapsed into a single number that is rolled,
as it was before the refactor.
The following changes were made to the dice rolling code:
- Store Vec<Amount> on DicePool instead of single number to roll.
- New struct RolledDicePool to store result of a dice pool roll.
- Remove Display trait from DicePool, move it over to RolledDicePool.
- Separate extra dice pool info into DicePoolModifiers.
- DicePoolModifiers is shared between DicePool and RolledDicePool.
- Dice parsing and rolling now return standard Result objects.
This commit does NOT enable support of actually using variables. Any
dice pool roll containing a variable will result in an eror.
The command parser was also rewritten to use combine and rely on the
standard Result pattern.
Instead of using an Arc Mutex for state management embedded directly
into the bot, utilize actor pattern, with the idea that this will be
much more useful than simply logging a message once in the future.
This also refactors the bot code so that instead of a single run_bot
function, the DiceBot struct now has a run() method attached to it.
This also necessitated changes and cleanup to the dicebot main, which
is for the better anyhow.
The error and config types are also now in their own files, and
implemented for more in-depth use cases.
Updates to the latest matrix SDK, which has a new version of olm-sys
(must be dynamically linked at the moment). Also cleans up the
Dockerfile to remove rustup because Void has reached Rust 1.46.0, for
a faster build.
This gives us many things for free, like automated state management,
no need to declare special API structs and use HTTP requests directly,
and most importantly: ENCRYPTION!
