Short description for EVPlugBase 1.0 Beta (Palm): Manage hacks&plugins for PalmOS.EVPlugBase is a replacement of hackmaster. And it's a open platform for third-party developers to develop a Plugin for Palm OS. Plam OS is very succinct os system, but it's a little inconvenient. Many programers develop patchs for the system, some of them are based with Hack Master, a great platform for patchs, others are not. That was the internal reason that might crash the pilot.After we finished EVEdit, a Hack extension, we find it is necessary to develop a new mechanism to the programers who want to add some of the system patch trap in their applications. We name these applications "Plugin", different with "hack". What is lack of the Hack Master? 1.Not solve the hack conflict with the no-hack application problem. 2.Strictly resources requirement: Strictly resources ID requirement, for example, patch code ID must start from 'code' resource 1000, config panel resource ID must be 2000 etc. Strictly require 'TRAP' resource, it is very difficult for Code warrior programer. 3.Waste of code, for example, when a patch want to replace several system trap, normally a piece of init code needed in sereral place, that will waste a lot code. 4.Inflexible programing, for example, in different versioin of OS, SysKeyboardDialog trap is different, if you want to replace it in Palm OS 1.0, you must replace the SysKeyboardDialogV10 trap, but when you try in Palm OS 2.0, you must replace SysKeyboardDialog trap, so you must provide two version for these two OS. When we are developing EVEdit (A HackMaster extention), we feel these inconvenient deeply, so we develop EVPlugBase, to manage Plugins for Palm OS. The enhancement list below: 1.EVPlugBase can manage all Plugin written according EVPlugBase rule. No conflict each other. 2.EVPlugBase can manage all other no-hack applications that replace system traps. 3.Provide delete-protection. This prevent some users to delete Plugin or Hackextention which is actived, that will mostly cased a system crash. 4.Provide SoftPenStroke function for Plugin. It will save many time of patch programer. 5.Solve all problem that list in the lack of Hack Master.
