Compileroption: output of list of global variables

[langinagel]

Hi,

since global variables are seen as the big satan we have to control them.

One supporting attempt can be the output of a list of global variables by the compiler.

This option should also be possible to choose by the editor.

Global variables are not "the big satan", but the effort to maintain a program grows as the number of global variables grows.
This is always the case, regardless whether or not the compiler is able to generate such a list. So it's generally recommendable to use global variables rarely, and to use them with care.
When you need such a list, there are likely far too much global variables in your program(s). Using global variables rarely in the first place is possible, and just a question of coding style. And with only half a dozen or less global variables in a program, no such list is needed.

1) avoid global vars
2) use "Define" on global scope, and "shared" on local Scope, so you need global vars only in very special cases

Define gvarname

Procedure test()
Shared gvarname

ProcedureReturn gvarname
endprocedure

3A) use modules and use only "modulwide" Variables, so you protect the other code from this vars
3B) generally make "modulewide" variables only public if this is realy needed

4) use a special polish notation for your globals (e.g. use "gvarname" instead of "varname", or in a module use "_varname", "m_varname2 or "myvarname" instead of "varname"

Personally I use global variables quite extensively, but I have them all defined in a single include file, and the name of every global variable starts with "g".

Today I learned I must prefix all my Global vars/strucs/constants/arrays/maps with 'evil_myVar'.

Fine,

we all learned now how to deal with global variables on an operational point of view (care for this, do that,..).

Maybe the requested function might as well be useful for those beginners or hobby-programmers who are not full aware what kind of variables are treated as global by the compiler and what are not.

Second attempt.
