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.

The number of failing commands are now printed out when at least one
command in a multi-command execution fails. This commit does not
introduce printing out WHICH commands failed, nor their error
messages.
There was also some minor refactoring to move command response
handling into their own functions (one for single response, one for
multiple) so that the code is more readable.

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.

Add get/insert functions for RoomInfo in the rooms db.
Move 'bot joins room' code to single method, so we can also record a
RoomInfo struct into the database.
Adds a new function `should_process` to rooms impl that determines if
calling could should proceed with processing an event ID. Event IDs
are recorded (along with room ID) as a key pointing to the
system-local timestamp of when the event was received. If the key was
not originally present, we instruct calling code to process the event.
Events are also asychronously recorded by timestamp using a sled event
watcher that listens to inserts in the main tree (described above).
This secondary tree will allow easy cleanup of old events in the
future.
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.
This gives it parity with the other systems: cofd and cthulhu. More
refactoring and a rewrite later as we trend towards more
system-specific implementations.
Also comes with reorganization of the dice rolling code to centralize
the variable -> dice amount logic, and changes the way the results of
those rolls are displayed.
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.
Only expose config settings via methods on the Config struct. This
allows default value handling to live entirely inside the config code,
solves various borrowing issues with the "create default bot config
value" solution, and allows us to avoid cloning the bot config values.
The downside is that the config must now be in an Arc since its
ownership is shared in multiple places and the matrix SDK requires
thread-safe types (perhaps in the future we re-compose traits and use
Rc for config instead).
This commit also further cleans up and splits up the bot code for the
matrix connection, notably making the main message event handler
smaller by splitting out the "should we process the message" checks
into a separate function.
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.
This commit lays the groundwork for a stateful dicebot, instead of one
that only responds to commands. It now maintains a simple state
machine, used to store the current state of the bot. Currently, it
only cares about whether or not the message about skipping old
messages was logged.
This makes the oldest message age setting optional, in additon to the
entire bot config (for now). If the oldest message age is not
specified (or if the entire bot config is missing), it will default to
15 minutes.
This behavior became broken again after switching away from the
macro-based command parsing. The bot would return any non !command
message as an error, which would cause it to read more messages, and
return those as errors, until finally the matrix SDK would throw up.
Command parser now more properly handles empty messages and
non-commands, but we also simply abort processing if the incoming
message doesn't start with an exclamation point.
