Instances is the repository that contains all externs Xcode project. These projects generate plugins that are used by MacMap. Externs are plugins that have various functions :

• Calc : functions that return a result (lenght, area...)
• Geog : functions that deals with geographic query (inside, containing...)
• Tool : functions that manage mouse and user interface with the main mapping window (select, zoom, scroll...)
• UserExt : umbrella functions that allows the user to create its own function (calc, macro, script...)
• Var : functions that return a result (π, current date...)
• XBox : functions for palettes windows managment
• XMap : generic functions (spreadsheet, undo/redo...)
• vDef : functions to define the graphical representation of objects

Compilation : You can open each project with Xcode then compile, or use xcodebuild in a terminal window. As plugins are linked to MacMap frameworks, you have to build MacMapSuite.framework, MacMapStats.framework, and internal MacMap frameworks (mox_intf.framework, std_ext.framework...) before building components.

Note: MacMap projects are currently built with Xcode 11 against Mac OS X 10.12 SDK.

Installation location : Plugins are installed in the standard MacMap plugins directory.
