Debugger v0 supported breakpoints, call-stack inspection and stepping through the program. Version 1 added object inspection and watch expressions. Also it has special support for strings and limited support for arrays. This version is available in binary distribution. 1. Installation…
In the first version of the Debugger : So far debugger is available only in Argentum compiler built from sources. This is the way to build *.ag application with debug info (and with no optimizations): This debug info is lldb/dwarf…

Argentum can call C/C++ functions and pass parameters of primitive data types and objects. On Argentum side: Create a module io.ag and declare there a number of functions with “;” in place of body: On C/C++ side: Create a library:…
Module source file contains three parts (order matters): Dependencies In this example moduleA is used without name imports, thus all names of that module can be referred using long names: moduleA_functionfromModuleA For example: sys_getParent. While moduleB is used with imports.…
General program structure Argentum program consists on modules. All module sources are placed in the same directory in text files having “.ag” extension. File name matches module name. One module is passed to the compiler as starting module name. Compiler…
