642932a403 * Implemented a non-persistent cache in src/cache.py. The cache is lost when restarting the server but it has the advantage of not hitting the database, and so is useful for implementing things that should be remembered over time but does not need to be persistently saved in the database at every point, like fast-updating combat systems, timers etc. Using the cache can substantially cut down on database access at the cost of memory comsumption. It is easiest accessed through the object model using normal dot notation. So to store a variable in volatile memory e.g. from your script parent, you can do things like self.scripted_obj.cache.myvariable = variable and be sure that later (unless there was a reboot) doing self.scripted_obj.cache.myvariable will return the value you stored there.
* OBS - doing e.g. self.scripted_obj.myvariable = variable was always iffy and since a few revisions back this will NOT work - this is because the objects are now consistently synced with the database (in the past this was not done consistently which caused strange behaviour).
* Fixed some bugs in the multi-word command handler. It can handle multi-word exits as well now.

af19724bb2 Make sure player input is valid unicode. If an un-decodable character is encountered, replace it with question marks. We'll need to test this with a more unicode capable client than I have. 2009-10-27 20:18:01 +00:00

a711e07b80 Added the capability of evennia commands to consist of more than one word. So the examples.red_button parent can now be pressed with the command 'push button' instead of 'pushbutton' as before. The variable COMMAND_MAXLEN in the config defines how many words your commands may maximum contain (don't set it higher than needed for efficiency reasons).
The main drawback of multi-word commands are that they can not have any switches; they are intended for in-game use (in states and on objects). Use normal one-word commands for administration and more complex commands with many options.

84aeabb272 Some cleanup. Fixed all examples to match the changes in the states and help systems, also
ran them through pylint to pretty them up.

8074617285 Largely rewrote and refactored the help system.
The help entry database structure has changed! You have to resync or purge
your database or your will get problems!

New features:
* Help entry access now fully controlled by evennia permissions
* Categories for each help entry
* All entries are created dynamically, with a See also: footer calculated
  after the current state of the database.
* Indexes and topic list calculated on the fly (alphabetically/after category)
* Added auto-help help entries for all default commands.
* Only shows commands _actually implemented_ - MUX help db moved into 'MUX' category
  which is not shown by default.
* More powerful auto-help markup - supports categories and permissions (and inheritance).
* Global on/off switch for auto-help, when entering production
* Auto_help_override switch for selectively activating auto-help when developing
  new commands (like the old system).
* Refactored State help system; no more risk of overwriting global help entries.
* State help now defers to main help db when no match found; makes system more transparent.
* State help entries also support categories/permissions (state categories are not
  used much though).

Other updates:
* Added more commands to the batch processor
* Many bug-fixes.

66095a0b16 Implemented locks.
The main command to use is @lock, which accept three types of locks at the moment, and three types of keys:
 Locks: DefaultLock, UseLock, EnterLock
 Keys: ObjectIDs, Groups, Permissions
This offers the most useful functionality - stopping people from picking up things, blocking exits and stopping
anyone from using an object.
If the attributes lock_msg, use_lock_msg and enter_lock_msg are defined on the locked object, these will be used
as error messages instead of a standard one (so "the door is locked" instead of "you cannot traverse that exit").

Behind the scenes, there is a new module, src/locks.py that defines Keys and Locks. A Locks object is a collection
of Lock types. This is stored in the LOCKS attribute on objects. Each Lock contains a set of Keys that might be
of mixed type and which the player must match in order to pass the lock.

cdd4770330 Implemented clearcom as per MUX specifications (Issue 48).
Added a 'clear' argument to addcom as a shortcut to clearcom.
Changed addcom to now change the alias to a new one if giving the command on an already subscribed channel.
Added the exception in command handler so that giving the channel alias without argument gives an error instead
of sending None to the channel.

1d4f075ca7 * Updated and expanded the State system; the API changed a bit. You now have to first *create* the state using
GLOBAL_STATE_TABLE.add_state() before adding commands to it. The state can now be much more configured by including as much or as
little of the normal default commands into it as wanted (so you can now have states which are almost as normal, except some
commands are missing or change their behaviour ... illness or darkness comes to mind). The possibilities here are limitless.
* States now also optionally allow traversing exits as well as using command tables defined on objects.
* States now better handle error messages (so if you try 'look' in a state which does not contain a look command you will no
longer get the 'Huh?' but will be told that the command is not available at the moment).
* All examples in commands/examples/ have been updated to use the new State system. Also added a @test_state function for trying out
the functionality.
* Added hooks at_before_move() and at_after_move(), useful for character based move-restrictions and checks (e.g. movement speed)
* Minor tweaks to the event system; avoiding the counters to go negative should they hit an uncaught traceback.
* Small fixes of typos and minor extra safety checks.

ffa03309fc Local object command tables are now in. See game/gamesrc/parents/examples/red_button.py for example. Note that local command matches will override global matches. Command handler short circuits on the first command match. This will typically be the object with the lowest ID. 2009-04-25 06:11:42 +00:00

b3c386a2c3 Clean up some of the methods on the script parent system. I have no idea why I was being silly and passing things around through dictionaries. Yick. Also added a at_player_creation method to basicplayer.py that is triggered after player objects are created and ready to go, but before they are logged in. 2009-03-30 00:54:05 +00:00

9407eb0ee4 Huge overhaul in the way objects and sessions are used with commands. We now pass all commands through objects (aside from unlogged commands), which means session.msg() is now deprecated for any use other than unlogged out.
As a side-effect of all of this, logging in more than once acts as behaves now. Also, this will allow things/rooms/exits (IE: not players) or un-logged in players to run commands or be forced to run them via @fo. All of this will bring us more in-line with MUX behavior.

This should work as expected without the "finally", as the exception will raise after the log message.

66a529ba84 The command handler has been completely overhauled and is actually readable now. It -might- be a little faster as well. It's not really that point in development to start micro-optimizing, so I haven't ran any benchmarks.
Our command evaluation now mirrors MUX2's. It was kind of weird before now, I'm not really sure how it got so out of order. In any case, I'm no longer ashamed of our command handler code. Hooray.

d58f4eb517 Looking through our command code after a long hiatus, I realized that it was pretty much awful. So here's part 1 of the command interpreter overhaul.
- The command handler has been drastically simplified. We were doing way too much processing in the handler that should have been done in the individual command functions themselves.
- The 'cdat' dict we were previously passing around has been replaced with a Command object that has useful methods for performing some of the parsing command functions will probably want to do from time to time.
- All commands were updated to use the new Command object, tested, and cleaned up in general.
- A lot of formatting was cleaned up.
- A lot of previously un-found bugs and limitations were fixed.
- The 'page' command has been broken out into its own file, since it's going to have a number of functions that would otherwise clutter commands/general.py.

Expect a commit (probably later today) that will clean up the second half of cmdhandler.py.

37d66093cc Addition of a re-usable CommandTable class. We still have two global command tables that are now instances of this class. Game developers will use methods on CommandTable to add their own commands without modifying the base server code.
This is also in preparation of allowing commands to be present on objects via their script parents.
