1.1 ABOUT THIS MANUAL
------------------------
The point of this manual is to describe how the plugin technically works so
it's easier for other developers to make modifications or join the development.
1.2 BRIEFING
---------------
The entire plugin is based on events in the game. It has a lot of features and
each feature is separated in its own module. Events are then forwarded to those
modules.
There are core modules and optional modules. Core modules is features and stuff
that cannot be disabled and is required for the plugin to function. Optional
modules like respawning, sound effects or weapon restrictions can be disabled.
Each module takes care of its own task. But modules have dependency, and events
should be forwarded in correct order. Usually only core modules depends on other
core modules. Optional modules should be independent.
2.0 PLUGIN CORE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.0 LOG MODULE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.1 DESCRIPTION
------------------
A plugin with a lots of modules and events needs a good logging system. The
user should be able to decide what's logged with logging flags.
3.2 LOGGING FLAGS AND FILTERS
--------------------------------
The log system decides what to log based on some generic log flags. Those flags
are stored in a bid field (http://en.wikipedia.org/wiki/Bit_field).
An optional module filter can be enabled to only allow log events from user
specified modules.
For performance reasons there should be a single function that tells whether it
should log or not, based on the specified module and generic event. The logging
function itself should not do such check and always log a message when called.
(incomplete)
How to store module flags? Key/values? Reading those flags MUST be cheap, so
the overall plugin performance isn't affected.
3.3 FORMATTED LOG MESSAGES
-----------------------------
Each log message should tell the module and what part of it that fired the
log event. Also it must be possible to supply additional info as parameters
(the "any:..." parameter) to be used in the log message. These are easily'
parsed with VFormat.
3.4 THE LOG FUNCTION
-----------------------
Syntax:
LogMessageFormatted(client,
const String:module[],
const String:block[],
const String:message[],
type = LOG_FORMAT_TYPE_FULL,
any:...)
Parameter: Description:
---------------------------------------------------------------------------
client Specifies what client that triggered the event. Use -1 for
core events.
module What module the event was triggered in.
block What function or block that triggered the event.
message The log message. Can be formatted.
type Optional. Specifies what log type to use. Defaults to full.
any:... Formatting parameters for the log message.
Example usage with flag check:
if (LogCheckFlag(LOG_CORE_EVENTS, LOG_MODULE_CLASSES))
{
LogMessageFormatted(-1, "Classes", "Load", "Warning: Maximum classes reached (%d). Skipping other classes.", _, ZR_CLASS_MAX + 1);
}
The module check will be replaced with something other than defined constants.
