Here I Am!

This is an Ada wrapper applied to the Where Am I? library by Gregory Pakosz. As with the original C, this allows for easily locating where the running executable or module is stored in the filesystem.

Note that this functionality is not something you can do with the Ada standard library!

The Command_Name subprogram in Ada.Command_Line will only get you the command used to invoke the executable, which might be a symlink and/or might have had a platform-specific $PATH used to find it. The Current_Directory and Containing_Directory subprograms in Ada.Directories will only get you the current working directory. That may be completely different from where the executable is located if an absolute or relative path was supplied with the command or, again, a platform-specific $PATH was involved.

Of the options in the standard library the most reliable one would be to use Ada.Environment_Variables and process each possible platform-specific $PATH manually. But that still wouldn't resolve any symlinks or other shortcut files.

Building and Installation

If this was a dynamic library then the function to locate the current module would always return the location of that shared object. On the other hand if this was a static library then it wouldn't be possible to compile as part of a dynamic libary.

Thus, to use this you should instead just copy the contents of src wholesale to a suitable spot in your own project.

The tests.gpr project file can be used to build some very basic sanity checks if desired.
